‘Using anuran community diversity and Pseudacris crucifer to predict landscape quality across a land use gradient'

open access: yesWildlife Biology, EarlyView.
As human‐modified landscape and climate changes proliferate, maintaining biodiversity and understanding the function and quality of available habitat is imperative. As anurans (frogs/toads) such as Pseudacris crucifer, can be an indicator species of habitat quality and ecosystem productivity, studying the anuran community in a mixed‐land use region ...

Leafspot Disease Progression and Components of Resistance Among Selected Peanut Genotypes in Ghana

open access: yesLegume Science
Early and late leafspot diseases are major constraints in peanut production, causing up to 70% yield losses in combined occurrences. Phenotyping has focused mainly on disease incidence and severity with little attention on disease progression and ...

Evaluating machine learning models for multi‐species wildlife detection and identification on remote sensed nadir imagery in South African savanna

open access: yesWildlife Biology, EarlyView.
This research paper investigates the efficacy of leading machine learning (ML) models for detecting and identifying ungulate species in African savanna using nadir imagery from unmanned aerial vehicles (UAVs). Traditional aerial counting methods, while widely used, suffer from significant limitations in accuracy and precision, in part due to human ...

Selective foraging by aardvarks Orycteropus afer on termite mounds: influence of mound structure, spatial distribution, and geology in a savanna landscape

open access: yesWildlife Biology, EarlyView.
Predator foraging patterns reflect how animals interact with spatially heterogeneous resources, yet how these patterns manifest across complex landscapes remains poorly understood. We investigated selective excavation of termite mounds by aardvarks Orycteropus afer in Gonarezhou National Park, examining how mound structural characteristics, size ...

Interannual dynamic resource selection patterns of the northern bobwhite in a region with poor edaphic conditions

open access: yesWildlife Biology, EarlyView.
Understanding an organism's shifting resource needs throughout its life cycle is crucial for developing effective conservation strategies. Northern bobwhite Colinus virginianus populations have been declining for nearly a century due largely to habitat loss/degradation.

Local Ecological Knowledge Reveals the Distribution of Cryptic Nocturnal Wildlife 局域生态知识揭示隐秘夜行野生动物的分布

open access: yesWildlife Letters, EarlyView.
Many nocturnal animals are difficult to study because they are rarely seen, including nocturnal primates, galagos and pottos, in West Africa. Working with over 600 people in 52 villages in southern Guinea‐Bissau, we found that communities frequently recognized galagos by their red eyeshine and distinctive calls, while pottos were not known.

The singing phenology of Bachman's sparrow: implications for monitoring programs

open access: yesWildlife Society Bulletin, EarlyView.
We used automated recording units, weather data, and multiple logistic regression with generalized estimating equations to determine the annual singing period and influences on singing behavior of Bachman's sparrow in Texas, USA, surveying daily for 2 years.

Long‐term changes in functional diversity and its implications for mammalian conservation and ecological restoration in a grassland ecosystem

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Paleontological data provide information on natural environments prior to human influence, which are useful for tracking changes in ecosystem functioning through time. During the Late Pleistocene, about 10% of terrestrial mammalian species were extinct in South America.
