Distance sampling: comparing walked transects and road transects for rock ptarmigan densities and population trends

Wildlife Biology, EarlyView.
We compared population trends for rock ptarmigan Lagopus muta densities (2003‒2019) derived from walked transects and driven road transects in Mosfellsheiði and Slétta in southwest and northeast Iceland, respectively. The walked transects were laid out according to a random rule.

Use of Natural Springs by Raptors: Insights from Camera Traps in the Baja California Peninsula, Mexico

Diversity
Freshwater availability is one of the most pressing environmental concerns in arid ecosystems. The use of free-standing water by raptors has been little studied, and in the context of climate change has become increasingly important as extended droughts ...

Wildlife temporal behaviors in response to human activity changes during and following COVID‐19 park closures

Wildlife Biology, EarlyView.
With urbanization reducing the amount of available wildlife habitat, and outdoor recreation increasing the human activity within wildlife habitats, it is important to understand the effects of human activity on animal behavior. This study examined how the reduction in human presence in urban parks in Gainesville, Florida, affected the temporal ...

High migratory potential of fall armyworm in West Africa despite stable temperatures and widely available year‐round habitats

Insect Science, EarlyView.
Despite the minimal annual temperature variation and the widespread distribution of potential year‐round habitats in Ghana, the migratory potential of the local fall armyworm remains strong and is indistinguishable from that of the fall armyworm in China, which undergo seasonal migration.

Using multiple data sources to investigate foraging niche partitioning in sympatric obligate avian scavengers

Ecosphere, 2019
As carrion feeders competing for a limited and ephemeral resource, avian scavengers are ideal model organisms to study mechanisms of niche partitioning.

Body Size Regulates Niche Overlap Asymmetry in the Subtropical Andes Rain Shadow: Isotopic Paleoecology of Oligocene South American Ungulates

Integrative Zoology, EarlyView.
This study provides the first isotopic analysis of Oligocene mammals from Quebrada Fiera, Mendoza, Argentina, filling a major gap in South American paleontology. It reveals a latitudinal gradient in aridity due to the Andean rain shadow and highlights the role of (semi)permanent water bodies in sustaining diverse herbivore communities. Additionally, it

Two new reports of leucistic birds from Mexico

Huitzil
We present two new records of leucism in two bird species from two locations in Mexico. First, we report one leucistic Barn Swallow (Hirundo rustica); the individual was a nestling observed between 15 July and 6 August 2010, in a suburban area of ...

Weaponizing Nature, Naturalizing Violence: Anthropologies of Ecofascism

American Anthropologist, EarlyView.
ABSTRACT After decades of denial and obstruction, the global Right is increasingly willing to acknowledge that climate change is a threat to lives and lifeways everywhere. Moreover, some seize on the specter of ecological collapse to advance fascistic politics.

Multilocus sequence typing of Ornithobacterium rhinotracheale isolated from pigeons and birds of prey revealed new insights into its population structure

Veterinary and Animal Science, 2016
The sudden emergence of Ornithobacterium rhinotracheale (ORT) in commercially raised poultry species and its presence in non-galliform birds raise important epidemiological issues about the role of interspecies transmission.

Use of species’ responses to cryptic anthropogenic disturbances for monitoring biodiversity outcomes in tropical forests

Conservation Biology, EarlyView.
Abstract Measuring area‐based conservation outcomes in tropical forests is challenging due to cryptic human disturbances (e.g., hunting). As a result, comparative studies of management strategies providing quantitative outcomes remain scarce, especially in the Neotropics.
