Mapping area of habitat for inland wetland species. [PDF]

Conserv Biol
Abstract Area of habitat (AOH) maps provide a high‐resolution representation of the habitat available in a species’ range and can support conservation policy and planning processes. However, until recently, there was insufficient knowledge on the distribution of inland wetlands and freshwater biodiversity to develop AOH mapping methods specifically ...

Mapping the density of giant trees in the Amazon. [PDF]

New Phytol
Summary Tall trees (height ≥ 60 m) are keystone elements of tropical forests, strongly influencing biodiversity, carbon storage, and ecosystem resilience. Yet, their density and spatial distribution remain poorly quantified, especially in remote Amazonian regions, limiting our understanding of their ecological roles and contribution to forest–climate ...

Evaluating past and future contributions of conservation programs to species recovery. [PDF]

Conserv Biol
Abstract Impact evaluation of conservation actions is a crucial step in global efforts to curb the biodiversity crisis. Through robust impact evaluation, practitioners can assess the effectiveness of conservation strategies and optimize the use of limited resources.

Ecology of declining populations of gray foxes (Urocyon cinereoargenteus) in Indiana, USA Ecología de las poblaciones en declive de zorros grises (Urocyon cinereoargenteus) en Indiana, EE.UU.

Wildlife Monographs, EarlyView.
We estimated seasonal space use, cover selection, and resource selection; evaluated gene flow and potential genetic barriers; and assessed cause‐specific survival rates and reproduction of radiomarked gray foxes in Indiana, USA. Our results provide evidence that gray foxes in Indiana are an edge species with relatively large home ranges, relatively low

Identifying hotspots of faunal data deficiency to direct urgent research and monitoring

Conservation Biology, EarlyView.
Abstract Data deficiency is a substantial challenge for extinction risk assessments because incomplete data means we cannot accurately identify priority protected areas for conservation. Here, we use the International Union for Conservation of Nature (IUCN) distributions of amphibians, sharks and rays, fish, mammals, birds, and reptiles to identify ...

Improving efficiency in conservation planning by modeling species‐specific responses to threat abatement

Conservation Biology, EarlyView.
Abstract Reversing ongoing biodiversity loss requires effectively managing anthropogenic threats. Although conservation actions can mitigate these threats, prioritizing and targeting such actions remain challenging because species respond differently depending on the nature of the threats and their biological traits.

External structures at the nest‐site predict asymmetric architecture of nests in a mud‐building bird

Ibis, EarlyView.
In the animal kingdom, nests are essential structures and textbook examples of extended phenotypes. However, the relationship between builders, nest traits and the nest‐site remains poorly understood. We indirectly examine whether structures in the nest‐site influence nest‐building behaviour, specifically focusing on their effect on nest architecture ...
