Foraging and scavenging behaviour of the prairie rattlesnake (Crotalus viridis): no evidence that envenomation cues facilitate kleptoparasitism of struck prey

Amphibia-Reptilia, 2021
Most viperids are ambush predators that primarily use venom to subdue prey, employing a strike-release-trail hunting strategy whereby snakes follow the unique scent of envenomated prey to locate carcasses they have bitten and released.

Ecological implications and lessons from high pathogenicity avian influenza H5N1 2.3.4.4b in Antarctica

Ecological Solutions and Evidence, Volume 7, Issue 3, July–September 2026.
HPAI H5N1 was confirmed in 22 South Polar Skuas and one Kelp Gull on Dismal and Horseshoe Islands, Marguerite Bay, Western Antarctic Peninsula in early 2025, with high mortalities consistent with global trends. Rapid antigen tests showed 90% agreement with rRT‐PCR, supporting their utility for early detection in remote environments.

The stochastic modelling of kleptoparasitism using a Markov process [PDF]

Journal of Theoretical Biology, 2010
Kleptoparasitism, the stealing of food items from other animals, is a common behaviour observed across a huge variety of species, and has been subjected to significant modelling effort. Most such modelling has been deterministic, effectively assuming an infinite population, although recently some important stochastic models have been developed.

Use of an Honest Signal by Red-footed Boobies Sula sula in Response to Kleptoparasitism by Great Frigatebirds Fregata minor

Marine Ornithology
On Genovesa Island (00.3°N, 089.9°W) in the Galápagos Islands, Ecuador, Great Frigatebirds Fregata minor kleptoparasitize (i.e., steal food from) Red-footed Boobies Sula sula.

Seasonal Dynamics of Resource Availability and Human Presence Shape Habitat Use of Large Carnivores in Chad

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Seasonal variation in resource availability and human activity can strongly influence large carnivore space use, yet these dynamics remain poorly documented in Central African savannas. Using dry and wet season camera‐trap surveys in Zakouma National Park, Chad, we show that prey availability drives carnivore space use in the dry season, and that ...

Diversity and Spatiotemporal Activity Patterns of Medium and Large Mammals in the Niokolo‐Koba National Park, Senegal

Ecology and Evolution, Volume 16, Issue 7, July 2026.
The Niokolo‐Koba National Park in southeastern Senegal, a mosaic of savannah and forest habitats, supports a diverse assemblage of medium‐ and large‐sized mammals. Our camera‐trap survey revealed comparable species richness across habitats, higher evenness in savannahs and during the wet season, and generally consistent sighting rates across habitats ...

Quantitative targets for leopard conservation in sub‐Saharan Africa

Journal of Applied Ecology, Volume 63, Issue 7, July 2026.
By integrating density modelling with habitat suitability, we provide a decision‐support framework for leopard conservation across sub‐Saharan Africa. The results identify where conservation investment is most likely to yield demographic gains, support the re‐evaluation of national hunting quotas against sustainable offtake thresholds and offer an ...

Museomics and phylogenomics with protein-encoding ultraconserved elements illuminate the evolution of life history and phallic morphology of flesh flies (Diptera: Sarcophagidae)

BMC Ecology and Evolution, 2021
Background The common name of the Flesh flies (Sarcophagidae) usually relates them with organisms feeding on decomposing organic matter, although the biology of one of the largest radiations among insects also includes predation, coprophagy, and even ...

Nest‐box supplementation can amplify intraspecific exploitation: RFID reveals frequent nest switching and lower fledging success in barn owls

Journal of Applied Ecology, Volume 63, Issue 7, July 2026.
High breeding density in nest box‐based biological control programs can unintentionally increase intraspecific exploitation, reducing fledging success even when apparent reproductive output remains high. Management evaluations should move beyond occupancy and fledgling counts to include individual‐level performance metrics, such as fledging success ...

Avian Infrastructures: Urban Experiments and the Makings of a Seabird ‘Hotel’

The Geographical Journal, Volume 192, Issue 2, June 2026.
Short Abstract The paper focuses on the relationship between infrastructure, animal architectures and avian geographies to explore the development of ‘kittiwake hotels’—artificial nesting structures for black‐legged kittiwakes. Drawing on a collaboration between cultural geography and marine ecology that moves between the United Kingdom and Norway, the
