Estimating large carnivore populations in an arid fenced reserve using spatial capture–recapture modelling

Wildlife Biology, EarlyView.
In fenced protected areas where large carnivore populations persist or have been restored through reintroduction, population monitoring is essential to inform management. Robust density estimates are particularly important given the strong influence of large carnivores on ecosystem processes, yet such data remain scarce for arid systems where ...

Challenges in the conservation and management of legal reserve areas in Brazilian grassland and savanna ecosystems in the face of global climate change [PDF]

Pesquisa Agropecuária Brasileira
Legal reserve areas (LRAs) are a fundamental part of the Brazilian conservation strategy, together with permanent preservation areas. The LRAs are intended to maintain biodiversity and can be managed sustainably.

Nutrients in an African Savanna: the consequences of supply heterogeneity for plants and animals [PDF]

, 2010
In savannas, trees and grasses co-exist and share resources such as water and nutrients. The ratio between the tree and grass components (i.e., vegetation structure) importantly controls productivity, animal assemblages and earth-atmosphere feedbacks.

Livestock grazing and geodiversity modulate wild herbivore distributions in an African community conservation area

Wildlife Biology, EarlyView.
The rapid decline of African wildlife populations demands immediate action to mitigate further losses and restore ecosystems. A key factor influencing wildlife distribution is the relationship between the energetic needs of species and the availability of forage, both in terms of quality and quantity.

First insights into the movement patterns of maned wolf with sarcoptic mange

Wildlife Biology, EarlyView.
Understanding how infectious diseases influence wildlife behavior, particularly in habitats undergoing modification, is crucial for predicting disease outbreaks, assessing impacts on population fitness, and mitigating human health risks. Sarcoptic mange can alter wildlife movement and space use, yet its effects on threatened carnivores remain unclear ...

Mapping Vegetation Morphology Types in Southern Africa Savanna Using MODIS Time-Series Metrics: A Case Study of Central Kalahari, Botswana

Land, 2015
Savanna ecosystems are geographically extensive and both ecologically and economically important; they therefore require monitoring over large spatial extents.

Integrating large mammalian herbivores into Dynamic Global Vegetation Models: Status and next steps

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Zoogeochemistry, the study of how animals influence elemental cycling within ecosystems, bridges the fields of zoology, ecology and biogeochemistry. Yet, most terrestrial ecosystem models, especially Dynamic Global Vegetation Models (DGVMs), remain largely plant‐centric

Goose herbivory alters soil microbial community functional potential in a sub‐Arctic wetland

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Herbivory alters below‐ground resource dynamics via direct and indirect mechanisms, yet its effects on microbial functional potential remain poorly understood. This limits our understanding of the mechanisms that link animal, plant and microbial functional roles in ...

Cenozoic Tectonics Ignite Mitochondrial Codon Innovations Propelling Canid Body Size Evolution and Transcontinental Radiations

Integrative Zoology, EarlyView.
We decode mitochondrial genomes across all extant canids, revealing lineage‐specific codon optimization driven by altitude, predation, and body size. A tripartite framework integrates geological events, metabolic constraints, and adaptive radiation to explain carnivore evolution.
