Habitat variables influencing bird assemblage patterns across maize and legume fields before and after harvest in West Africa

Wildlife Biology, EarlyView.
Though agriculture has been linked to the decline in bird populations due to the associated changes in vegetation structure and composition, its potential to sustain birds has been explored over time. A sustainable agricultural landscape should be one that has the capacity to support bird species all year.

Variation in population size, nest distribution, colony extent, and timing of movements at the largest known parrot colony

Wildlife Biology, EarlyView.
Psittaciformes are among the most threatened birds, and population size and trend estimates are needed to aid conservation. The burrowing parrot Cyanoliseus patagonus is undergoing substantial changes in its population size, due to habitat degradation, trapping for the pet trade, and persecution as crop pest.

Host species and age‐specific variation on Hepatozoon prevalence and its effect on body condition in two Neotropical crocodiles

Wildlife Biology, EarlyView.
Many populations of species belonging to the order Crocodilia are threatened due to illegal trafficking, indiscriminate hunting, and habitat loss and degradation affecting crocodilian health and parasitic load. Although several studies have revealed that crocodiles, caimans, and alligators are frequently infected by Hepatozoon spp., the results from ...

Results of the global conservation assessment of the freshwater crabs (Brachyura, Pseudothelphusidae and Trichodactylidae): The Neotropical region, with an update on diversity

ZooKeys, 2014
The freshwater crabs of the Neotropics comprise 311 species in two families (Pseudothelphusidae and Trichodactylidae) and one or both of these families are found in all of the countries in the Neotropical region (except for Chile and some of the ...

Assessing the current distribution and potential habitat availability for Kaempfer's tody‐tyrant: a restricted‐range and threatened species from the Atlantic Rainforest

Wildlife Biology, EarlyView.
Human disturbances are threatening biodiversity worldwide, and species with restricted geographic distribution or small population sizes are more likely to become extinct. The prevention of extinctions is an urgent matter and knowledge on the ecology and distribution of threatened species is required to outline conservation strategies.

Big Cat Mortality in Subsistence Hunts in Amazonia 亚马孙雨林地区生计狩猎中的大型猫科动物致死情况研究

Wildlife Letters, EarlyView.
We use data from a participatory biodiversity monitoring program to estimate the annual mortality of jaguars and pumas resulting from subsistence hunts in two Amazonian Extractive Reserves. We estimate that around 50 big cats are killed annually in the study area, which is consistent with an independent estimate for the same area and within the same ...

First record of Neoempheria Osten Sacken (Diptera, Mycetophilidae) biology in the Neotropical region, with associations between its larvae and fungi

Biodiversity Data Journal, 2015
Background Members of the family Mycetophilidae (Diptera) have life cycles that are typically associated with fungus. Their biology is relatively well known in the Palaearctic, though other regions are poorly known, and there are no associations recorded
