Mineral profile and histopathological findings in the liver of white-lipped frog (Leptodactylidae) from the morphoclimatic domain of the Caatingas, Brazil.

This study aimed to investigate the mineral profile and histopathological findings in the liver of Leptodactylus macrosternum (white-lipped frog) and to assess the association between melanomacrophage areas and hepatic fungal granuloma with several factors such as weight, snout-cloacal length, sex, hepatosomatic index, season (dry and rainy), and condition factor K. A total of 135 frogs of different ages were collected from three areas in the city of Petrolina, Pernambuco, with varying land use (conventional agriculture, organic agriculture, and Caatinga stricto sensu). The liver of all specimens exhibited changes such as granulomatous lesions, inflammatory cell infiltrate, blood vessel congestion, and sinusoid dilation. The melanomacrophage areas were influenced by weight, snout-cloacal length, and hepatosomatic index. Our findings revealed a positive correlation between body size (weight and snout-cloacal length) and melanomacrophage/hepatic granuloma, while the hepatosomatic index showed a negative relationship. For the condition factor K, only age presents relationship. Eleven elements were quantified for the mineral profile, with aluminum (Al), iron (Fe), and zinc (Zn) being the most abundant in both liver and muscle. Although the histopathological findings and mineral profile of the liver and muscle in this study indicate an effect on the health of L. macrosternum in different collection areas, confirming the relationship between environmental characteristics and these findings requires future studies. Furthermore, long-term studies would be necessary to allow the monitoring of all stages of development of these populations, from tadpoles to adults, for a better evaluation of these effects in L. macrosternum.

Sepsis sensitizes behavioural amphetamine responses while inducing inflammatory and neurotrophic vulnerability in the cecal ligation and puncture model.

The present study aimed to evaluate if sepsis sensitizes behavioural and biochemical responses induced by m-amphetamine. For this, Wistar rats were submitted to the cecal ligation and puncture. After 30 days of cecal ligation and puncture procedure, the animals were submitted to a single intraperitoneal injection of saline or m-amphetamine (.25, .50, or 1.0 mg/kg). Locomotor behaviour was assessed 2 h after the administration. Interleukin (IL)-1ß, IL-6, IL-10, tumour necrosis factor-α, dopamine-cAMP-regulated phosphoprotein of 32,000 kDa (DARPP-32) and neuronal calcium sensor (NCS-1) levels were evaluated in the frontal cortex, hippocampus and striatum. Also, brain-derived neurotrophic factor (BDNF), neuronal growth factor and glial-derived neurotrophic factor levels were assessed in the hippocampus. M-amphetamine alone (.25 and 1.0 mg/kg) increased rats' locomotion and exploratory behaviour compared with the Sham + Sal. Animals from the cecal ligation and puncture + m-amphetamine (.5 and/or 1.0 mg/kg) group showed an increase in locomotion, exploratory and risk-like behaviour when compared with the Sham + Saline group and with its respective Sham groups. Cecal ligation and puncture increased interleukin levels compared with the Sham + Sal. However, cecal ligation and puncture animals that received m-amphetamine (1 mg/kg) increased even more, these inflammatory parameters compared with the Sham + Sal and the cecal ligation and puncture + saline group. M-amphetamine at lower doses increased neurotrophic factors, but higher doses decreased these parameters in the brain of cecal ligation and puncture rats. M-amphetamine dose-dependently increased DARPP-32 and NCS-1 levels in cecal ligation and puncture rats in some structures. In conclusion, these results demonstrate that sepsis sensitizes behavioural amphetamine responses while inducing inflammatory and neurotrophic vulnerability in the cecal ligation and puncture model.

Potential mechanisms of action of resveratrol in prevention and therapy for mental disorders.

There is a growing body of evidence about the potential of diet and nutrients to improve the population's mental health and the treatment of psychiatric disorders. Some studies have suggested that resveratrol has therapeutic properties in mental disorders, such as major depressive disorder, bipolar disorder, Alzheimer's disease, and autism. In addition, resveratrol is known to induce several benefits modulated by multiple synergistic pathways, which control oxidative stress, inflammation, and cell death. This review collects the currently available data from animal and human studies and discusses the potential mechanisms of action of resveratrol in prevention and therapy for psychiatric disorders.

Prenatal Stress Induces Long-Term Behavioral Sex-Dependent Changes in Rats Offspring: the Role of the HPA Axis and Epigenetics.

Preclinical genetic studies have related stress early exposures with changes in gene regulatory mechanisms, including epigenetic alterations, such as modifications of DNA methylation, histone deacetylation, and histones acetylation. This study evaluates the effects of prenatal stress on the behavior, hypothalamus-pituitary-adrenal (HPA)-axis, and epigenetic parameters in stressed dams and their offspring. The rats were subjected to a protocol of chronic unpredictable mild stress on the fourteenth day of pregnancy until the birth of offspring. After birth, maternal care was evaluated for six days. Following weaning, the locomotor and depressive-like behaviors of the dams and their offspring (60 days old) were assessed. The HPA axis parameters were evaluated in serum from dams and offspring, and epigenetic parameters (histone acetyltransferase (HAT), histone deacetylase (HDAC), DNA methyltransferase (DNMT) activities, and the levels of histone H3 acetylated at lysine residue 9 (H3K9ac) and histone 3 acetylated at lysine residue 14 (H3K14ac)) were assessed in dams' and offspring' brains. Prenatal stress did not significantly influence maternal care; however, it induced manic behavior in female offspring. These behavioral alterations in the offspring were accompanied by hyperactivity of the HPA-axis, epigenetic adaptations in the activity of HDAC and DNMT, and acetylation in the histones H3K9 and H3K14. In addition, the prenatal stressed female offspring showed increased levels of ACTH compared to their male counterpart. Our findings reinforce the impact of prenatal stress on behavior, stress response, and epigenetic profile of offspring.

Folic acid does not have an anti-manic effect but protect the brain against oxidative stress in an animal model of mania induced by ouabain.

BACKGROUND: Bipolar disorder (BD) is a complex and severe mental disorder that affects 1-3 % of the world population. Studies have suggested the involvement of oxidative stress in the physiopathology of this psychiatry disorder. Folic acid (FA), a vitamin from the B complex, is a nutraceutical that has recently been researched as a possible treatment for BD since folate is reduced in patients with the disorder. The present study aimed to evaluate the effects of lithium (Li) and FA on behavioral changes and oxidative stress parameters in an animal model of mania induced by ouabain (OUA). METHODS: Wistar rats received a single intracerebroventricular (ICV) injection of OUA or artificial cerebrospinal fluid (aCSF). From the day following ICV injection, the rats were treated for seven days with gavage injections of Li (47.5 mg/kg/mL), FA (50 mg/kg/mL), or water (1 mL/kg). On the 7th day after OUA injection, locomotor activity was measured using the open-field test. In addition, the oxidative stress parameters were evaluated in rats' frontal cortex, striatum, and hippocampus. RESULTS: OUA induced mania-like behavior and oxidative stress in rats' brains, but Li could reverse these alterations. FA did not affect behavior parameters; however, it presents an antioxidant effect on the brain structures evaluated. LIMITATIONS: The study was only evaluated male rats and ICV injection is an invasive procedure. CONCLUSION: These results indicate that even though FA has an effect against the oxidative stress induced by OUA, this effect was not strong enough to interfere with behavior parameters.

Evaluation of metal exposure through the composition of essential and toxic micro-minerals in freshwater turtles (Phrynops geoffroanus) from a Brazilian river.

This study aimed to evaluate metal exposure through the concentration of essential and toxic micro-minerals in biological samples of Phrynops geoffroanus from an anthropized river. The work was carried out in four areas with different flow characteristics and uses of the river, where individuals of both sexes were captured during the dry and rainy seasons. The elements Al, Cd, Co, Cr, Cu, Fe, Mn, Mo, Ni, Pb, and Zn were quantified in samples of serum (168), muscle (62), liver (61), and kidney (61) by inductively coupled plasma optical emission spectrometry. The concentration of the elements varied according to the sample type, being higher in the liver and the kidney. In the serum, many elements were below the limit of quantification, but it was possible to determine Al, Cu, Fe, Mn, Pb, and Zn. The liver showed high levels of Cu, Fe, Pb, and Zn, and muscle for Fe, Ni, Pb, and Zn, with most of the elements accumulated in the kidney (Al, Cd, Co, Cr, Mn, Mo, and Ni) relative to other tissues. There was no significant difference between the sexes in the accumulation of elements. Between seasons, Cu was higher in serum and Mn in muscle and liver in the dry period, while in the kidney, almost all the elements were higher in the rainy period. The concentrations of the elements in the samples indicated a high degree of environmental contamination, representing risk in the use of the river and consumption of food from local fisheries.

Profile of judicialization in access to antineoplastic drugs and their costs: a cross-sectional, descriptive study based on a set of all lawsuits filed between 2016 and 2018 in a state in the Northeast Region of Brazil.

BACKGROUND: The judicialization of the acquisition of medication for healthcare is not restricted to Brazil but can also be found in other Latin American countries, despite the existence of a universal health system in the case of Brazil, the Unified Health System (known as the SUS). Right-to-medicines litigation has existed ever since the emergence of a high demand for treatment of Acquired Immuno-deficiency Syndrome (AIDS) but the current focus is on cancer. Pharmaceutical Assistance (PA) is the area within the SUS that is responsible for ensuring access to medication and the aim of this article is thus to draw up a profile of litigation related to PA in one economically significant state in the Northeast Region of Brazil, in terms of the following characteristics of lawsuits: the plaintiff filing the lawsuit; medical and health information; the cost of acquiring the requested medications; and the proportion accounted for by spending on antineoplastic drugs. METHODS: A cross-sectional, descriptive study was conducted of lawsuits filed between 2016 and 2018 at the Litigation Center of the State of Pernambuco Department of Health. RESULTS: A total of 2,947 lawsuits containing at least one requested medication were analyzed. The majority of the plaintiffs were male (51.7%); 49.8% of the requests originated in the Unified Health System (SUS), and plaintiffs were primarily patients in the Metropolitan region of the State capital, Recife. The most frequent cancers involved were those classified by the ICD as C61, C71 and C50. The median general expense on medications for the actions was U$1,734.94. Considering antineoplastic drugs alone, the cost exceeded U$7,500 per lawsuit over the three years, given that the median unit price for antineoplastic drugs is approximately US$65 compared to US$4 for non-antineoplastic drugs. CONCLUSION: The present study is of relevance to the field of public health and examines how a profile of such healthcare litigation can be used as a tool for managing and improving decision-making in times of economic austerity.

Imipramine Can Be Effective on Depressive-Like Behaviors, but Not on Neurotrophic Factor Levels in an Animal Model for Bipolar Disorder Induced by Ouabain.

INTRODUCTION: Despite possible risks of mania switching with the long-term use of antidepressants in patients with bipolar disorder (BD), these drugs may help in depressive episodes. Alterations in neurotrophic factor levels seem to be involved in the pathophysiology of BD. The present study aimed to evaluate the effect of acute treatment of imipramine on behavior and neurotrophic levels in rats submitted to the animal model for BD induced by ouabain. METHODS: Wistar rats received a single intracerebroventricular (ICV) injection of artificial cerebrospinal fluid or ouabain (10-3 M). Following the ICV administration, the rats were treated for 14 days with saline (NaCl 0.9%, i.p.), lithium (47.5 mg/kg, i.p.), or valproate (200 mg/kg, i.p.). On the 13th and 14th days of treatment, the animals received an additional injection of saline or imipramine (10 mg/kg, i.p.). Behavior tests were evaluated 7 and 14 days after ICV injection. Adrenal gland weight and concentrations of ACTH were evaluated. Levels of neurotrophins BDNF, NGF, NT-3, and GDNF were measured in the frontal cortex and hippocampus by ELISA test. RESULTS: The administration of ouabain induced mania- and depressive-like behavior in the animals 7 and 14 days after ICV, respectively. The treatment with lithium and valproate reversed the mania-like behavior. All treatments were able to reverse most of the depressive-like behaviors induced by ouabain. Moreover, ouabain increased HPA-axis parameters in serum and decreased the neurotrophin levels in the frontal cortex and hippocampus. All treatments, except imipramine, reversed these alterations. CONCLUSION: It can be suggested that acute administration of imipramine alone can be effective on depressive-like symptoms but not on neurotrophic factor alterations present in BD.

Evaluation of Physical Symptoms in Brazilian Conductors Through NMQ and DASH Instruments.

Few studies have investigated populations of conductors concerning their activity in general or work-related health aspects, although these individuals also face important work demands with the potential for develop¬ing hearing, physical, and vocal problems. This study was designed to assess physical symptoms (pain, tingling, numbness) in Brazilian conductors by applying the Nordic Musculoskeletal Questionnaire (NMQ) and the Disabilities of the Arm, Shoulder and Hand (DASH) Questionnaire. The data were collected online from 166 Brazilian conductors who were actively working for at least 1 year. The NMQ results indicated a high prevalence of symptoms in the shoulder, neck, and lumbar and upper back regions. Participants also complained of pain in the upper limbs, especially on the right side, and spinal regions associated with conducting. Bivariate statistical tests indicated significant relationships between the presence of symptoms in the upper limbs and higher disability scores in the DASH instrument. The body regions mentioned by the participants are similar to those reported in the few studies of conductors in the literature, highlighting that conducting has a specific physical impact and the potential to affect the function of the upper limb in the conductors' daily activities.

Chest binding and respiratory complaints in transgender men / Uso de binder e queixas respiratórias em homens transexuais

Abstract Introduction: Chest binders are an important resource for building masculinity in transgender men without mastectomy, although they can cause respiratory and thoracic damage if misused. Objective: To analyze the association between chest binding and chest complaints in transgender men. Methods: This was a quantitative cross-sectional study conducted at the Trans Space of the Hospital das Clínicas de Pernambuco and the LGBTQI Patrícia Gomes outpatient clinic of the Lessa de Andrade polyclinic in Recife (Pernambuco State, northeastern Brazil). Sixty transgender men aged >18 years were included, and data on sociodemographics, general health, chest binding, and respiratory complaints in the thoracic region were collected. Descriptive analysis was performed, and prevalence ratios (PR) were estimated with a confidence interval (CI) of 95% to associate between binder use and complaints in the chest region. Results: The average was 27.25 years, of which 81.7% did not undergo mastectomy and 53.3% used chest binders. The use of chest binders was significantly associated with complaints in the chest region (PR = 2.73), difficulty breathing (PR = 2.27), and chest pain (PR = 1.82). Conclusion: This study demonstrated a higher prevalence of complaints in the chest and respiratory region in transgender men who use chest binders. This reinforces the need to broaden the view on the health of this population. Gender construction strategies are essential for the quality of life and mental health of transgender men, and binders are an important ally in this process.

Resumo Introdução: O uso de binder é um importante recurso para a construção da masculinidade nos homens transexuais não mastectomizados, contudo, pode acarretar danos respiratórios e torácicos se usado de forma inadequada. Objetivo: Analisar a associação entre o uso de binder e as queixas torácicas em homens transexuais. Métodos: Estudo transversal quantitativo realizado no Espaço Trans do Hospital das Clínicas de Pernambuco e no ambulatório LGBTQI Patrícia Gomes da Policlínica Lessa de Andrade, em Recife, PE. Foram incluídos 60 homens transexuais, com idade acima de 18 anos, e foram coletadas informações sociodemográficas, de saúde geral, uso de binder e queixas na região torácica. Foi realizada a análise descritiva e estimadas as razões de prevalência (RP) com intervalo de confiança (IC) de 95% para a associação entre o uso de binder e queixas na região do tórax. Resultados: A média foi de 27,25 anos; destes, 81,7% não realizaram mastectomia e 53,3% faziam uso de binder. O uso de binder teve associação significativa com queixas na região do tórax (RP = 2,73), dificuldade para respirar (RP = 2,27) e dor no tórax (RP = 1,82). Conclusão: Este estudo demonstrou que há prevalência maior de queixas na região do tórax e queixas respiratórias nos homens transexuais que fazem uso de binder. Isto reforça a necessidade de ampliar o olhar sobre a saúde dessa população. Estratégias de construção de gênero são essenciais para a qualidade de vida e saúde mental de homens transexuais, sendo o uso de binder um importante aliado neste processo.

Helminth fauna and histopathology associated with parasitic infections in Phrynops geoffroanus (Schweigger, 1812) (Testudines, Chelidae) in a Brazilian river subjected to anthropogenic activities.

The objective of this study was to determine the structure of the helminth fauna and identify the macroscopic and histopathological alterations associated with parasitic infections in Phrynops geoffroanus. Freshwater turtles of both sexes were captured during the dry and rainy seasons in four municipalities along the Capibaribe River. The study included 63 animals, of which 79.37% (50/63) were parasitized by one or more helminths. In total, 933 helminths of seven taxa were recovered: Serpinema monospiculatus, Spiroxys figueiredoi, Nematophila grandis, Polystomoides brasiliensis, Cheloniodiplostomum testudinis, Telorchis birabeni, and Prionosomoides scalaris. Monogeneans and digenetic trematodes were more sensitive to environmental pressures, since the prevalences varied significantly between areas. Nematodes proved to be more resistant to environmental pressure and caused severe injuries to their hosts: nodules in the stomach and small intestine, adhesions in the liver capsule, and pulmonary emphysema. Parasitic granulomas were recorded at the infection sites and in the lungs and liver, the latter caused by migration of S. figueiredoi larvae. This is the first record of P. brasiliensis, N. grandis, C. testudinis, and T. birabeni parasitizing P. geoffroanus in the state of Pernambuco. Histopathology proved to be an important tool for studies on the impact of parasites at the individual, population, and ecosystem levels. Considering the use of the Capibaribe River for public water supply, fishing, and other activities, within the One Health perspective, this study demonstrates that the anthropogenic impact affects parasites and their hosts, in addition to the human population that uses this ecosystem.

A new species of the Dendropsophus decipiens Group (Anura: Hylidae) from Northeastern Brazil.

We describe a new species of the Dendropsophus decipiens Group, morphologically most resembling D. haddadi but genetically more closely related to D. oliveirai and likely endemic from the Atlantic Forest biome, northeastern Brazil. The new species can be distinguished from all species of the D. decipiens Group based on the combination of morphological features, advertisement call and phylogenetic position based on mitochondrial DNA gene sequences. The new species emits simple calls in series of 3-9 notes, each with 9-29 pulses, and dominant frequency varying from 5578-6422 Hz, and exhibit a minimum of 8% genetic distance (16S mitochondrial gene) in comparison to its congeners. The new taxa represent the sixth species of the D. decipiens Group, which likely harbors more undescribed taxa, corroborating the view that Neotropical species richness is fairly underestimated.

Two new species of Cosmocercidae (Nematoda: Cosmocercoidea) of Leptodactylus macrosternum Miranda-Ribeiro (Anura: Leptodactylidae) from Caatinga Biome, Brazil.

In the current study, two new species of Cosmocercidae nematodes parasitizing the anuran Leptodactylus macrosternum (Leptodactylidae) from two localities in the municipality of Petrolina, sub-middle São Francisco river, state of Pernambuco, Brazil, were described. Oxysomatium petrolinensis n. sp. differs from all congeneric species for having the male caudal papillae distribution pattern unique in this genus, in which the last three pairs of pre-cloacal papillae are located lateroventrally on the anterior border of the cloacal aperture. Additionally, the new species has an unpaired medial precloacal papilla, seven pairs of postcloacal papillae, and a relatively unique spicule size. Oxyascaris caatingae n. sp. differs from all congeneric species mainly for having males with a medial unpaired precloacal papilla and a distribution pattern of caudal papillae unique to this species, being the only species of the genus with adcloacal papillae. The current study proposes the description of Oxysomatium petrolinensis n. sp., fourth species and the first report of this genus in hosts from the Neotropical region. In addition, it describes Oxyascaris caatingae n. sp., which is the fifth species of the genus.

Efficacy of folic acid as an adjunct to lithium therapy on manic-like behaviors, oxidative stress and inflammatory parameters in an animal model of mania.

Evaluate the efficacy of folic acid (FA) as a therapeutic adjunct to lithium (Li) on the manic-like behaviors as well as parameters of oxidative stress and inflammation in an animal model of mania induced by m-amphetamine (m-AMPH). Wistar rats first received m-AMPH or saline (NaCl 0.9%, Sal) for 14 days. Between the 8th and 14th day, rats were treated with water, Li, FA or a combination of thereof drugs (Li + FA). Manic-like behaviors were assessed in the open-field test. Oxidative stress and inflammation parameters were assessed in the frontal cortex, striatum, and hippocampus. Administration of m-AMPH in rats significantly enhanced the exploratory and locomotor behaviors, as well as the risk-taking and stereotypic behaviors. Li + FA reversed these behavioral alterations elicited by m-AMPH. Administration of this psychostimulant also increased oxidative damage to lipids and proteins, whereas Li + FA reversed these oxidative damages. m-AMPH also induced an increase in the glutathione peroxidase (GPx) activity and a decrease in the glutathione reductase (GR) activity. Li + FA reversed the alteration in GR activity, but not in GPx activity. In addition, m-AMPH increased the IL-1ß and TNF-α levels in the rat brain; Li + FA combined therapy reversed the alterations on these inflammatory parameters. FA administration per se reduced the increased TNF-α content induced by m-AMPH. Present study provides evidence that FA is effective as an adjunct to Li standard therapy on manic-like behaviors, oxidative stress and inflammatory parameters in a model of mania induced by m-AMPH.

Effects of lithium and valproate on behavioral parameters and neurotrophic factor levels in an animal model of mania induced by paradoxical sleep deprivation.

The present study aimed to evaluate the effects of treatment with lithium (Li) and valproate (VPA) on behaviors and brain BDNF, NGF, NT-3, NT-4 and GDNF levels in mice submitted to paradoxical sleep deprivation (PSD), which induces an animal model of mania. Male C57BL/6J mice received an intraperitoneal (i.p.) injection of saline solution (NaCl 0.09%, 1 ml/kg), Li (47.3 mg/kg, 1 ml/kg) or VPA (200 mg/kg, 1 ml/kg) once a day for seven days. Animals were randomly distributed into six groups (n = 10 per group): (1) Control + Sal; (2) Control + Li; (3) Control + VPA; (4) PSD + Sal; (5) PSD + Li; or (6) PSD + VPA. Animals were submitted to 36 h of PSD, and then, they were submitted to the open field test. The frontal cortex and hippocampus were dissected from the brain. The manic-like behaviors in the mice were analyzed. Treatment with Li and VPA reversed the behavioral alterations induced by PSD. PSD decreased BDNF, NGF, and GDNF levels in the frontal cortex and hippocampus of mice. The administration of Li and VPA protected the brain against the damage induced by PSD. However, PSD and the administration of Li and VPA did not affect the levels of NT-3 and NT-4 in either brain structure evaluated. In conclusion, the PSD protocol induced manic-like behavior in rats and induced alterations in neurotrophic factor levels. It seems that neurotrophic factors and sleep are essential targets to treat BD.

Parasites of Gymnodactylus darwinii Gray, 1845 (Squamata, Phyllodactylidae) from an Atlantic Rainforest fragment.

Gymnodactylus darwinii is an endemic lizard from Atlantic Rainforest. Ecological aspects of your parasitic fauna are still unknown. Therefore, the goal of the present study was to know the composition of parasitic fauna of G. darwinii in an Atlantic Rainforest fragment, as well to test the influence of the size, sex and seasonality on parasitological indices. The study was carried out in two conservation units: Mata do Camucim and Mata do Tapacurá, both located in the municipality of São Lourenço da Mata, Pernambuco state, northeast region of Brazil. Sixty-five specimens were collected, of which 39 (569%) were parasitized by cystacanths of Acanthocephala (prevalence 43%; mean intensity 4 ± 9.9; mean abundance 3.82 ± 7.87), Geckobia sp. (Acari, Pterygosomatidae) (prevalence 30.7%; mean intensity 4 ± 15.0; mean abundance 3.74 ± 9.54), Physaloptera sp. larvae (Nematoda, Physalopteridae) (prevalence 4.6%; mean intensity 1 ± 0.47; mean abundance 0.06 ± 0.47) and Paradistomum rabusculum (Trematoda, Dicrocoeliidae) (prevalence 1.2%; mean intensity 1; mean abundance 0.02). Acanthocephalans presented a significant relation with the animal length (r² = 0.31, p = 0.006, n = 28). Infestation by Geckobia sp. was more frequent during the dry season (BLM: p = 0.001), while the infection by Acanthocephalans was frequent in dry and rainy seasons, with no significant variation (BLM: p = 0.78). In addition, the most prevalent parasites showed no significant difference in relation to sex: males and females showed similar infestation intensity by Geckobia sp. (BLM: p = 0.31) and infection by Acanthocephala (BLM: p = 0.34). This is the first study about the parasitic ecology of G. darwinii, representing a significant contribution to the conservation of this species and the ecosystem in which they inhabit.

Herpetofauna of five "Brejos de Altitude" of the interior of the state of Pernambuco, Northeastern Brazil

Brejos de altitude are found at high altitudes, generally over 600 meters above sea level, in mountainous and plateau regions throughout the Brazilian Northeast. These relict altitudinal forests display unique biota evolutionary characteristics, due to, mainly, the geological time they have spent isolated, where they serve as islands for biological specialization, with many registered endemisms. Studies that provide basic data on herpetofauna are important to understand the structure and composition of these communities. In this context, the present study aimed to compile an inventory of the herpetofauna of five brejos de altitude in the state of Pernambuco, Brazil, and compare its snake taxocenosis with that of other Caatinga localities in Northeastern Brazil. The areas were inventoried through different time, sampling and methodologies number of people and the use or not of traps. Literature data and scientific collections were used to complement the species list. A total of 88 species were recorded in all five study areas,: 32 amphibians (two orders, 8 families and 15 genera) and 56 reptiles (2 orders, 18 families and 44 genera). Four species of lizards found in the present study are endangered, and one tortoise and snake species are data deficient (DD).

Herpetofauna of the Northwest Amazon forest in the state of Maranhão, Brazil, with remarks on the Gurupi Biological Reserve.

Understanding the biodiversity of an area is the first step for establishing effective interventions for conservation, especially when it comes to herpetofauna, since 4.1% and 9.2%, respectively, of Brazilian amphibians and reptiles are endangered. The aim of this study is to identify the composition of the herpetofauna occurring in the Northwest Amazonian state of Maranhão, with a focus on the Gurupi Biological Reserve and surrounding areas. Samples were collected between May 2012 and October 2013 (18 months), through pitfall traps, time constrained active search, and opportunistic encounters, and these records were supplemented by specimens collected by third parties and by bibliographic records. A total of 131 species were recorded: 31 species of amphibians and 100 species of reptiles (six testudines, 30 lizards, two amphisbaenas, 60 snakes and two alligators), including some species new to the state of Maranhão and the northeast region of Brazil. This inventory contributes to the knowledge of the herpetofauna for the Belém Endemism Center, the most devastated region of the Brazilian Amazon, and considered poorly sampled.
