Conservation Management Strategies Shape Glucocorticoid Levels in African Elephant Populations More Than Parasite Load

open access: yesJournal of Zoology, EarlyView.
Understanding the factors influencing physiological stress is essential for interpreting how wildlife responds to contrasting environmental and management conditions. Across 19 South African elephant populations, we found that smaller reserves, self‐drive tourism, and high elephant density under low vegetation productivity were associated with elevated

Temporal Responses and Direct Encounters Among Native and Invasive Carnivores: Behavioral Evaluation Using Artificial Bait Sites

open access: yesJournal of Zoology, EarlyView.
At artificial bait sites, raccoon dogs (Nyctereutes procyonoides) exhibited delayed temporal responses to red foxes (Vulpes vulpes) despite dominating direct encounters. In contrast, the invasive masked palm civet (Paguma larvata) showed no significant temporal responses toward either native species (raccoon dogs and red foxes), despite consistently ...

Dam Management in the Era of Climate Change

open access: yesMathematical Finance, EarlyView.
ABSTRACT Climate change has a dramatic impact, particularly by concentrating rainfall into a few short periods, interspersed with long dry spells. In this context, the role of dams is crucial. We consider the optimal control of a dam, where the water level must neither exceed a designated safety threshold nor fall below a minimum level to ensure ...

Changes in food‐web pathways and ecosystem functions after sidearm re‐connection in a large river (Danube, Austria)

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction River regulation schemes generally led to changes in riverine assemblage composition and their trophic status, which often is reflected in a general loss or decrease of characteristic species and a concomitant increase or dominance of generalist species.
