Livro Vermelho dos Mamíferos de Portugal Continental

A publicação deste Livro Vermelho, o primeiro inteiramente dedicado aos mamíferos, teve a ambição de ir bastante além do seu objetivo central – avaliar o risco de extinção das espécies de Portugal Continental. Entre os objetivos suplementares deste projeto incluem-se: (i) compilar toda a informação existente sobre a ocorrência de mamíferos no território nacional, como dados museológicos, resultados de censos e ...

The importance of including spatial autocorrelation when modelling species rich...

One of the aims of island biogeography theory is to explain the number of species in an archipelago. Traditionally, the variables used to explain the species richness on an island are its area and distance to the mainland. However, increasing evidence suggests that accounting for other variables is essential for better estimates. In particular, the distance between islands should play a role in determining spec...

How to map potential mesovoid shallow substratum (MSS) habitats? A case study ...

Understanding habitat extension that limits species distribution is a crucial tool for management and conservation, in which habitat mapping plays a pivotal role. The mesovoid shallow substratum (MSS) is a type of shallow subterranean habitat with an important conservation value for invertebrate communities, functioning as climatic/reproductive refuge, biogeographic corridor and/or permanent habitat. Methodolog...

The Influence of the Interaction between Climate and Competition on the Distrib...

It is known that species’ distributions are influenced by several ecological factors. Nonetheless, the geographical scale upon which the influence of these factors is perceived is largely undefined. We assessed the importance of competition in regulating the distributional limits of species at large geographical scales. We focus on species with similar diets, the European Soricidae shrews, and how interspecific...

Behavioral responses of rural and urban greater white-toothed shrews (Crocidura...

The development of urban areas imposes challenges that wildlife must adapt to in order to persist in these new habitats. One of the greatest changes brought by urbanization has been an increase in anthropogenic noise, with negative consequences for the natural behavior of animals. Small mammals are particularly vulnerable to urbanization and noise, despite some species having successfully occupied urban environ...

Deep mitochondrial introgression and hybridization among ecologically divergent...

The completion of speciation is typically difficult to ascertain in rapidly diverging taxa but the amount of hybridization and gene flow in sympatry or parapatry contains important information about the level of reproductive isolation achieved. Here, we examined the progress in speciation between the Mediterranean (Microtus duodecimco- status) and the Lusitanian pine vole (M. lusitanicus), which are part of the m...

Mapping the Impact of Digitisation for Poorly Documented Countries: Mozambique ...

Sharing the Decision Process Framework to Identify Well-supported Records of Ma...

Mapping Knowledge Gaps of Mozambique’s Terrestrial Mammals

A valuable strategy to support conservation planning is to assess knowledge gaps regarding primary species occurrence data to identify and select areas for future biodiversity surveys. Currently, increasing accessibility to these data allows a cost-effective method for boosting knowledge about a country's biodiversity. For understudied countries where the lack of resources for conservation is more pronounced to...

Predation risk modulates diet-induced obesity in male C57BL/6 mice

Objective In this study, the behavioral and physiological changes induced by experimentally varying the risk of predation in male mice fed a high-fat diet were examined. In particular, the study aimed to assess whether the risk of being predated modulates the body weight gain, providing an ecological context for the obesity resistance observed in many species of small mammals. Methods Body weight, food intake, ...
