Large‐scale characterization of horizontal forest structure from remote sensing optical images

Remote Sensing in Ecology and Conservation, EarlyView.
Sub‐meter resolution remote sensing data and tree crown segmentation techniques hold promise in offering detailed information that can support the characterization of forest structure from a horizontal perspective, offering new insights in the tree crown structure at scale.

Can Environmental Markets Pay for More Sustainable Farm Dams? A Cost–Benefit Analysis

Sustainable Development, EarlyView.
ABSTRACT Farm dams are widespread artificial waterbodies that play a critical role in agricultural water security. Enhancing these systems through sustainable interventions such as fencing, hardened access points, and revegetation can improve water quality and deliver carbon and biodiversity co‐benefits.

Home range and core area characteristics of urban and rural coyotes and red foxes in southern Wisconsin

Wildlife Biology, EarlyView.
Second‐order habitat selection is influenced by a variety of factors, including individual‐ and species‐specific traits and resource requirements, as well as landscape characteristics. By comparing home range characteristics across individuals, species, and landscapes, we can draw conclusions regarding whether and how different factors influence home ...

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

Wildlife 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 ...

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

Wildlife 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 ...

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

Legume 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 ...

Climate‐induced shifts in long‐term tropical tree reproductive phenology: Insights from species dependent on and independent of biotic pollination

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The dependence on biotic pollination may constrain plant phenological responses because flowering time ultimately defines reproductive success. We proposed a local‐scale study combining long‐term phenology and experimental data to evaluate how a key functional trait—the

Mammalian herbivory indirectly shapes savanna arthropod communities but only at very low or high levels

Journal of Animal Ecology, EarlyView.
This study investigates how large mammalian herbivores shape arthropod communities in African savannas, using a broad gradient of herbivory types and intensities to assess these effects under real‐world, non‐experimental conditions. Abstract Savanna ecosystems support unique biodiversity and provide livelihoods for millions of people.
