RESUMO
Resumen En este trabajo se presenta una lista actualizada de los anfibios distribuidos en el departamento de Loreto, Perú, incluyendo información sobre el estado de conservación a nivel internacional y nacional, el endemismo y zonas con vacíos de información. Se utilizó literatura herpetológica, bases de datos y especímenes de la colección del Departamento de Herpetología del Museo de Historia Natural de la Universidad Nacional Mayor de San Marcos para la elaboración de esta lista. Se registraron un total de 232 especies, con los anuros (sapos y ranas) representando el 96% del total de anfibios en Loreto. Dieciocho especies son endémicas de Loreto mientras que la gran mayoría (208 especies) tienen una distribución altitudinal por debajo de los 500 m. Diez especies están en categorías de amenaza y cuatro son consideradas casi amenazadas según criterios internacionales, mientras que cuatro están consideradas como amenazadas y seis como casi amenazadas en el listado nacional. Se observa mayor vacío de información en áreas cercanas a las fronteras con Brasil y Colombia.
Abstract This paper presents an updated list of the amphibians occurring in the department of Loreto, Peru, including information on conservation status, endemic species and areas with information gaps. Herpetological literature, databases and the collection of the Department of Herpetology of the Natural History Museum of the National University of San Marcos were used to update the species list. A total of 232 species were recorded, with anurans (toads and frogs) representing 96% of amphibians in Loreto. eighteen species are endemic to Loreto while the vast majority (208 species) have an altitudinal distribution below 500 m. Ten species are in threatened categories and four are near threatened according to international criteria; while four are considered as threatened and six as near threatened according the national list. Mayor information gaps are observed in areas near the borders with Brazil and Colombia.
RESUMO
BACKGROUND: A central aspect of professional identity is occupational commitment, which has a significant relationship with motivation and positive mental states in healthcare environments. However, it is not clear how occupational commitment is related to teaching practices in universities. AIM: To apply the Occupational Commitment Questionnaire (OCQ) to university teachers and relate its results with the Teaching Practices Questionnaire. MATERIAL AND METHODS: OCQ and Teaching Practices Questionnaire were answered by 319 university teachers from 13 Chilean regions, who were selected through a non-probabilistic volunteer sampling. Data collection was done after informed consent. An exploratory factor analysis was performed for OCQ. The internal consistency of each factor was calculated with Cronbach's Alpha. Spearman correlations were used to explore the relationship between the two questionnaires. RESULTS: Two factors were identified in OCQ, namely Teacher Commitment and Ethical-Professional Commitment. Cronbach's Alpha was 0.85 for both factors. A moderate direct relationship between teacher commitment, ethical-professional commitment, and the Teaching Practices Questionnaire was found. CONCLUSIONS: OCQ showed an adequate internal consistency, and it was directly related with teaching practices. Committed teachers had better teaching practices. This confirms the importance of teachers' values and perceptions on their professional performance.

Resumen En este estudio se investigó la dieta de la lagartija neotropical Liolaemus polystictus en la región Huancavelica en los Andes centrales del Perú. Los ítems de la dieta fueron identificados en los contenidos estomacales de 54 muestras. El porcentaje de contenido volumétrico vegetal fue mayor al animal (V% contenido animal= 22.97 y V% contenido vegetal= 77.03), siendo el contenido animal representado por los artrópodos y con diez ítems alimentarios. Considerando solo el contenido animal, los coleópteros fueron los más representativos (N%= 32.05, FO=59.26 y V%= 41.36). Ninguna categoría animal mostró valores de IRI altos para ser considerados fundamentales, asimismo la selección de presas no mostro diferencias significativas entre machos, hembras y juveniles, ni entre los contenidos volumétricos vegetales entre adultos y juveniles, pero sí en los contenidos volumétricos vegetales entre machos y hembras. Se encontraron diferencias significativas entre la longitud, ancho y volumen de la presa y el ancho de la cabeza (AC) en machos de L. polystictus. Finalmente, proponemos la categoría de herbívoro para la especie L. polystictus, lo cual elevaría a ocho las especies del grupo L. montanus que se alimentan principalmente de vegetación.
Abstract This study assessed the diet of the Neotropical lizard Liolaemus polystictus from Huancavelica region in the Peruvian central Andes. The diet composition was identified from 54 sample stomach contents. Percentage of vegetable content was higher than the animal one (V% animal content= 22.97 and V% vegetable content= 77.03), and arthropods were the highest animal content with ten foods items. Within the animal content, Coleoptera were the most representative (N%= 32.05, FO= 59.26 and V%= 41.36%). No animal category showed high IRI values to be considered fundamental. There were not significant differences on prey selection between males, females and juveniles, and on vegetal volumetric contents between adults and juveniles. However, vegetal volumetric contents were significantly different between males and females. Significant differences were found between prey length, width and volume and L. polystictus male head width (AC). Finally, we pro-pose L. polystictus to be considered an herbivorous species, which bring to eight the number of species in the L. montanus group that feed mainly on vegetation.
RESUMO
BACKGROUND: Occupational identity is defined as the perception of occupational interests, abilities, goals, and values, and the structure of the meanings that link these self-perceptions to career role. We developed an occupational identity questionnaire suitable to be used with university teachers. AIM: To evaluate the psychometric properties of the Occupational Identity Questionnaire (OIQ) and relate its results with those of the Teaching Practices questionnaire. MATERIAL AND METHODS: The OIQ and Teaching Practices Questionnaire were answered by 311 university teachers along Chile, who were selected through a non-probabilistic volunteer sampling. An exploratory factor analysis was performed and the internal consistency of each factor was calculated with Cronbach's Alpha. Spearman correlations were used to explore the relationship between the two questionnaires. RESULTS: Two factors were identified in OIQ: Teaching Vocation and Sense of Competence. Cronbach's Alpha was 0.75 for teaching vocation and 0.82 for the sense of competence. There was a moderate direct relationship between teaching vocation, sense of competence and the results of the Teaching Practices Questionnaire. CONCLUSIONS: OIS has an adequate internal consistency, its factorial structure showed two different types of identities and it is directly related to the results of the Teaching Practices Questionnaire.

Three new species of Rock Geckos Cnemaspis lineogularis sp. nov., C. phangngaensis sp. nov., and C. thachanaensis sp. nov. of the chanthaburiensis and siamensis groups are described from the Thai portion of the Thai-Malay Peninsula. These new species are distinguished from all other species in their two respective groups based on a unique combination of morphological characteristics, which is further supported by mitochondrial DNA (mtDNA) from the NADH dehydrogenase subunit 2 gene (ND2). Cnemaspis lineogularis sp. nov. is differentiated from all other species in the chanthaburiensis group by having a smaller maximum SVL 38 mm, 13 paravertebral tubercles, enlarged femoral scales, no caudal bands, and a 19.5-23.0% pairwise sequence divergence (ND2). Cnemaspis phangngaensis sp. nov. is differentiated from all other species in the siamensis group by having the unique combination of 10 infralabial scales, four continuous pore-bearing precloacal scales, paravertebral tubercles linearly arranged, lacking tubercles on the lower flanks, having ventrolateral caudal tubercles anteriorly present, caudal tubercles restricted to a single paraveterbral row on each side, a single median row of keeled subcaudals, and a 8.8-25.2% pairwise sequence divergence (ND2). Cnemaspis thachanaensis sp. nov. is distinguished from all other species in the siamensis group by having 10 or 11 supralabial scales 9-11 infralabial scales, paravertebral tubercles linearly arranged, ventrolateral caudal tubercles anteriorly, caudal tubercles restricted to a single paravertebral row on each side, a single median row of keeled subcaudal scales, lacking a single enlarged subcaudal scale row, lacking postcloaclal tubercles in males, the presence of an enlarged submetatarsal scale at the base if the 1st toe, and a 13.4-28.8% pairwise sequence divergence (ND2). The new phylogenetic analyses place C. punctatonuchalis and C. vandeventeri in the siamensis group with C. punctatonuchalis as the sister species to C. huaseesom and C. vandeventeri as the sister species to C. siamensis, corroborating previous hypotheses based on morphology. The discovery of three new karst-dwelling endemics brings the total number of nominal Thai Cnemaspis species to 15 and underscores the need for continued field research in poorly known areas of the Thai-Malay Peninsula, especially those that are threatened and often overlooked as biodiversity hot spots.
