How wildlife respond to tropical cyclones: short‐term tactics and long‐term impacts

Biological Reviews, EarlyView.
ABSTRACT From butterflies to lizards and from sharks to seabirds, wildlife exhibit tactics to survive the impacts of tropical cyclones, also known as hurricanes, cyclones, or typhoons depending on where they occur. Some species seek refuge during the storm by moving, some remain in place and ride it out, and others move longer distances, avoiding the ...

Removal of sorghum stover from feed choices has no confounding effect on the quantity and quality of diets selected by group or individually fed sheep

Journal of Applied Animal Research, 2023
The study determined the effect of reducing dietary ingredients and group feeding on diet selection, nutrient intake and digestibility in choice-fed sheep. Three feeds comprising of veld hay (VH), sorghum stover (SS) and maize stover (MS) were offered ad-

Developing a macroecology for human‐altered ecosystems

Ecography, EarlyView.
Although anthropogenically‐induced ecological disruptions are fundamentally important in defining ecosystem properties, they are largely overlooked by macroecological theory. Anthropogenic disruptions and their effects are generally not comparable to one another, nor to disturbances that are part of natural disturbance regimes.

Bridging Cross‐Scale Science–Policy Interfaces for Coherent Land‐Use Governance: Knowledge Co‐Production and Uptake in Kenya's Polycentric System

Environmental Policy and Governance, EarlyView.
ABSTRACT Land is fundamental to livelihoods and ecosystem health but faces mounting pressure from human activities, climate change, and competing development demands. Science–policy interfaces (SPIs)—platforms that connect experts and policymakers—are vital for co‐producing knowledge to inform coherent, sustainable land‐use governance.

Evaluating Several Vegetation Indices Derived from Sentinel-2 Imagery for Quantifying Localized Overgrazing in a Semi-Arid Region of South Africa

Remote Sensing, 2022
Rangeland monitoring aims to determine whether grazing management strategies meet the goals of sustainable resource utilization. The development of sustainable grazing management strategies requires an understanding of the manner in which grazing animals

Letting People in: Redefining Collaboration in Wildland–Urban Interface Governance

Environmental Policy and Governance, EarlyView.
ABSTRACT Intensifying wildfire regimes and expanding human settlements into wilderness areas have heightened concerns about the wildland–urban interface (WUI) due to the associated increase in fire risk. However, the WUI presents broader social‐ecological challenges that go beyond wildfire risk and remain understudied.
