ROSSI, J-P. 2011. rich: an R package to analyse species richness. Diversity 3(1):112-120. doi: 10.3390/d3010112.
Abstract. The paper describes rich, a new R package to perform species richness estimation and comparison. Species richness is the simplest surrogate for the more complex concept of species biodiversity. It is relatively easy to assess although estimations strongly depend on sampling intensity with the consequence that richness estimations should be standardized to perform valid comparisons. The R package rich allows such corrections as well as the computation of various statistics and implements different randomization tests to compare cumulative and average species richness of two communities. These tests are useful for ranking sites or communities which is a classical goal in restoration ecology and conservation biology.

Modeling impacts of climate change on giant panda habitat
SONGER, M.; DELION, M.; BIGGS, A.; HUANG, Q. 2012. Modeling impacts of climate change on giant panda habitat. International Journal of Ecology, v 2012, Article ID 108752, 12 pages. doi: 10.1155/2012/108752.
Abstract. Giant pandas (Ailuropoda melanoleuca) are one of the most widely recognized endangered species globally. Habitat loss and fragmentation are the main threats, and climate change could significantly impact giant panda survival.We integrated giant panda habitat information with general climate models (GCMs) to predict future geographic distribution and fragmentation of giant panda habitat. Results support a major general prediction of climate change—a shift of habitats towards higher elevation and higher latitudes. Our models predict climate change could reduce giant panda habitat by nearly 60% over 70 years. New areas may become suitable outside the current geographic range but much of these areas is far from the current giant panda range and only 15% fall within the current protected area system. Long-term survival of giant pandas will require the creation of new protected areas that are likely to support suitable habitat even if the climate changes.

Journals - Conheça os periódicos
Dia desses, enquanto procurava por periódicos
científicos nos quais eu poderia publicar meus artigos, descobri alguns
periódicos que nunca havia ouvido falar. A opção de periódicos disponíveis para
publicação científica é enorme, variando em termos de assuntos abordados,
acesso aos artigos da revista, Taxa de Publicação, abrangência do
público-alvo... Todos estes fatores (entre outros) determinam o que é chamado
de “fator de impacto” da revista, e permitem determina a qualidade da revista.
A CAPES (Coordenação de Aperfeiçoamento de
Pessoal de Nível Superior) usa estes fatores para determinar uma categorização
de qualidade dos periódicos – sendo A1, o mais elevado, seguidos de A2, B1, B2,
B3, B4, B5, e C, a qualificação mais baixa. Esta qualificação varia de acordo
com a área de conhecimento; p.e., o periódico Journal of Mammalogy é categorizado pela CAPES como B1 para as
áreas de Biodiversidade, mas para Administração ela é categorizada como C. Para
Ciências Biológicas, as áreas de Conhecimento da CAPES são: Ciências Biológicas
I (biologia geral, genética), Ciências Biológicas II (morfologia, fisiologia,
bioquímica, biofísica, farmacologia), Ciências Biológicas III (imunologia,
microbiologia, parasitologia), Biodiversidade (ecologia, oceanografia,
botânica, zoologia). Mais informações em:
As opções para publicação de artigos sobre
mamíferos é grande. Há periódicos especializados em mamíferos, como o Journal of Mammalogy e a Mastozoología Neotropical, e há
periódicos especializados em áreas de conhecimento específicas que também
publicam estudos com mamíferos. Pensando nestas várias opções, decidi criar
aqui no blog um tipo de “série”, apresentando alguns dos vários periódicos
científicos onde é possível publicar artigos sobre mamíferos. A princípio,
serão dois periódicos por mês, nos dias 15 e 30 (ou 28, em fevereiro). De cada
periódico serão apresentadas as seguintes informações: home page (link direto
para o site do periódico), Qualis da CAPES (considerando as áreas Ciências
Biológicas I – CBI, Ciências Biológicas II – CBII, Ciências Biológicas III –
CBIII e Biodiversidade – BDIV), se há ou não Taxa de Publicação (o autor
precisa pagar para publicar o artigo), os idiomas aceitos para publicação, a
disponibilidade de acesso aos artigos (se o periódico disponibiliza os artigos
gratuitamente ou se são pagos), a forma de submissão de artigo, e uma breve
descrição do escopo do periódico, baseado na descrição que encontra-se no site
do mesmo. Com relação ao Qualis da CAPES, colocarei apenas o Qualis atualizado;
aqueles marcados com “*” ainda estão em atualização. Para maiores informações
veja o site do WebQualis da CAPES (http://qualis.capes.gov.br/webqualis/principal.seam). O termo "Journals" será usado como marcador para todas as postagens deste tipo, além de assuntos relacionados ao periódico.
O objetivo é apresentar os frequentadores do
blog algumas opções para publicação de seus próprios artigos, ou locais onde
procurar pesquisas relacionadas. Acredito que será de especial ajuda aos
iniciantes na área de pesquisa com mamíferos.

Conservation strategy for brown bear and its habitat in Nepal
ARYAL, A.; RAUBENHEIMER, D.; SATHYAKUMAR, S.; POUDEL, B.S.; JI, W.; KUNWAR, K.J.; KOK, J.; KOHSHIMA, S.; BRUNTON, D. 2012. Conservation strategy for brown bear and its habitat in Nepal. Diversity 4(3):301-317. doi: 10.3390/d4030301.
Abstract. The Himalaya region of Nepal encompasses significant habitats for several endangered species, among them the brown bear (Ursus arctos pruinosus). However, owing to the remoteness of the region and a dearth of research, knowledge on the conservation status, habitat and population size of this species is lacking. Our aim in this paper is to report a habitat survey designed to assess the distribution and habitat characteristics of the brown bear in the Nepalese Himalaya, and to summarize a conservation action plan for the species devised at a pair of recent workshops held in Nepal. Results of our survey showed that brown bear were potentially distributed between 3800 m and 5500 m in the high mountainous region of Nepal, across an area of 4037 km2 between the eastern border of Shey Phoksundo National Park (SPNP) and the Manasalu Conservation Area (MCA). Of that area, 2066 km2 lie inside the protected area (350 km2 in the MCA; 1716 km2 in the Annapurna Conservation Area) and 48% (1917 km2) lies outside the protected area in the Dolpa district. Furthermore, 37% of brown bear habitat also forms a potential habitat for blue sheep (or bharal, Pseudois nayaur), and 17% of these habitats is used by livestock, suggesting a significant potential for resource competition. Several plant species continue to be uprooted by local people for fuel wood. Based on the results of our field survey combined with consultations with local communities and scientists, we propose that government and non-government organizations should implement a three-stage program of conservation activities for the brown bear. This program should: (a) Detail research activities in and outside the protected area of Nepal; (b) support livelihood and conservation awareness at local and national levels; and (c) strengthen local capacity and reduce human-wildlife conflict in the region.

Composição e abundância relativa dos mamíferos de médio e grande porte no Parque Estadual do Turvo, Rio Grande do Sul, Brasil
KASPER, C.B.; MAZIM, F.D.; SOARES, J.B.G.; OLIVEIRA, T.G.; FABIÁN, M.E. 2007. Composição e abundância relativa dos mamíferos de médio e grande porte no Parque Estadual do Turvo, Rio Grande do Sul, Brasil. Revista Brasileira de Zoologia 24(4):1087-1100.
Abstract. Composition and relative abundance of the medium-large sized mammals of Turvo State Park, Rio Grande do Sul, Brazil. Between January of 2005 and December of 2006, studies on the composition and relative abundance of medium and large sized mammals were carried out in Turvo State Park. Records came from camera-trapping, in addition to visualization and presence and absence data from track surveys along pre determined transects. At total, 29 species of medium-large sized mammals were listed. Of these, Dasyprocta azarae Lichtenstein, 1823 and Sylvilagus brasiliensis (Linnaeus, 1758) were the most frequently found. For carnivores, the majority of records were for Nasua nasua (Linnaeus, 1766) and Leopardus pardalis (Linnaeus, 1758), whereas Leopardus tigrinus (Schreber, 1775), Leopardus wiedii (Schinz, 1782) and Galictis cuja (Molina 1782), had the least. Among the ungulates, only Pecari tajacu (Linnaeus, 1758) showed frequent records, ranking fourth overall. Some species, common to other environments, showed few records at Turvo State Park, such as Dasypus novemcinctus Linnaeus, 1758 and Didelphis albiventris Lund, 1840. Data was suggestive of the probable local extinction of Tayassu pecari (Link, 1795) in the Park. The conservation of the medium and large sized mammals of this conservation area is strongly associated with the conservation of the “Misiones Green Corridor”, which probably represents a source area for many species.
