ABSTRACT
Abstract: The Spiny Red Lobster has an important commercial role in Brazil. However, a downward trend in the production of lobsters due to overfishing has been observed and there is also a devaluation of the product in the international market due to the instability in the size pattern of lobsters commercialized. Here in Brazil we detected two issues regarding the Spiny Red Lobster: (1) According to recent studies, there are genetic and morphological differences between Caribbean and Brazilian populations, which may be considered different species and; (2) Current legislation, such as seasonal closures, does not consider the multiple probable stocks of the species, which have direct implications in management and conservation. Thus, the recognition of the Spiny Red Lobster from Brazil as Panulirus meripurpuratus and investments on population and biological research are essential to improve its management considering regional stock differences.
Resumo: A lagosta vermelha tem um importante papel comercial no Brasil, porém, uma tendência de queda na produção de lagostas devido a sobrepesca tem sido observada e há também uma desvalorização do produto no mercado internacional devido à instabilidade no comprimento das lagostas comercializadas. Aqui no Brasil, detectamos dois problemas em relação à lagosta vermelha: (1) De acordo com estudos recentes, existem diferenças genéticas e morfológicas entre as populações caribenha e brasileira e; (2) Atualmente a legislação não considera os múltiplos estoques prováveis da espécie. Desta forma, os períodos de defeso sazonais não consideram os diferentes estoques, o que tem implicações diretas no manejo e na conservação. Logo, o reconhecimento da lagosta vermelha do Brasil como Panulirus meripurpuratus e investimentos em pesquisas biológicas e populacionais são fundamentais pra facilitar seu manejo considerando diferenças regionais nos seus estoques.
ABSTRACT
Genuine medicinal materials-Fritillariae Cirrhosae Bulbus and its active components are widely used in clinical medicine in China and even in many countries in the world because of their good medicinal effect. However, with the increase of the demand for the resources of Fritillariae Cirrhosae Bulbus, and the low yield of itself, the small number of seeds under natural conditions, the extremely low germination rate and survival rate and so on, the wild resources of Fritillariae Cirrhosae Bulbus are endangered. This paper summarized researches of several aspects like herbal research of Fritillariae Cirrhosae Bulbus, distribution of wild source plant resources and its influencing factors, conservation measures, and using endophyte to extract Fritillaria alkaloids, based on the articles published by China National Knowledge Internet and Web of Science. Hoping to provide some development ideas for the protection of wild source plant resources of Fritillariae Cirrhosae Bulbus from the perspectives of traditional conservation measures and active products extracted by microbial vigorously developed at this stage, so as to realize the balance of supply and demand of Fritillariae Cirrhosae Bulbus as soon as possible.
ABSTRACT
The present study was carried out to assess food and foraging niches of carnivorous bird species in mixed fruit orchard selecting two transects I and II at Punjab Agricultural University campus from March 2015 to February 2016. There were observed 12 and 11 carnivorous bird species out of total 52 and 38 bird species recorded in transect I and II respectively. Habitat features (hedgerows, un-cemented water channel), irrigation schedules and fruit developmental stages seemed to determine the bird composition, especially carnivorous bird species in mixed fruit orchard
ABSTRACT
El presente trabajo constituye una investigación referencial sobre los efectos que las acciones humanas causan a la tierra al utilizar inadecuadamente los recursos y las medidas que se deben tomar, con el objetivo de crear conciencia para evitar la venganza del planeta si colapsara como medio de sustento de los seres vivientes en ese proceso de acción antropogénica y reacción física del planeta Gaia (metáfora de Lovelock). Se describen las características físicas de Gaia. Se discuten los tres impactos ambientales globales: Efecto Invernadero, Calentamiento y Cambio Climático y Ruptura de la Capa de Ozono; y se esbozan las principales acciones institucionales e individuales para evitar/retardar la venganza de la tierra.
The present paper aims to describe the results of human actions on Planet Earth, due mainly to inadequate use of natural resources and discuss eventual measures that should be applied as to generate cousciousness and avoid theplanet´s revenge as a collapse of its capabilities for human sustenance within the process of anthropogenic and physical reaction of the planet: Gaia (Lovelock´s metaphor). Physical characteristics of Gaia are described. The three main environnental global impacts are discussed: green house effect, global warning, climate change and ozone layer hole. Institutional and individual actions aimed to avoid/delay earth´s revenge are outlined.
