New records of odontocete and mysticete predation by orcas in the Humboldt current system, South Pacific Ocean

Frontiers in Marine Science
Orcas (Orcinus orca) are the top marine predators of the ocean, targeting multiple taxa including teleost fishes, elasmobranchs, seabirds, sea turtles, pinnipeds, odontocetes and other large cetaceans.

The late-Quaternary megafauna extinctions: Patterns, causes, ecological consequences and implications for ecosystem management in the Anthropocene

Cambridge Prisms: Extinction
Across the last ~50,000 years (the late Quaternary) terrestrial vertebrate faunas have experienced severe losses of large species (megafauna), with most extinctions occurring in the Late Pleistocene and Early to Middle Holocene.

Comparative species distribution model framework for marine conservation and its application to loggerhead turtles in the Mediterranean

Conservation Biology, EarlyView.
Abstract Modeling species distributions in dynamic pelagic environments remains challenging, particularly for wide‐ranging and highly mobile species when there is limited guidance on model performance. This limitation constrains the effective use of species distribution models (SDMs) in marine conservation, where robust and transferable predictions are

Animal Teachers: Nonhuman Pedagogy and the Question of Deceit

Educational Theory, EarlyView.
Abstract Animals as “teachers” of human children and adults is a recurring theme in children's literature, in anthropological accounts of “feral children,” as well as in contemporary practices of animal‐assisted pedagogy, philosophical research, wildlife documentaries, and popular culture.

Lack of Compliance in Gillnet Fisheries Regulations Increases Risk to a Vulnerable Species

Fisheries Management and Ecology, EarlyView.
ABSTRACT This article presents an analysis of regulatory compliance in a Brazilian gillnet fishery, based on Vessel Monitoring System (VMS) tracking data. Satellite transmissions records, interpreted as proxies for gillnet haulings events, were analyzed and classified using a neural network to assess the level of compliance of the gillnet fleet.

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

Journal 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

Understanding marine biodiversity patterns and drivers: The fall of Icarus

Marine Ecology, EarlyView.
Abstract Biodiversity patterns are fundamental in our understanding of the distribution of life, ecosystem function, and conservation. In this concept analysis, A survey of the existing knowledge on marine biodiversity patterns and drivers across latitudes, longitudes, and depths indicates that none of the postulated patterns represent a rule.

The Formosan Black Bear and Taiwanese Nationalism

Nations and Nationalism, EarlyView.
ABSTRACT Building on scholarship that situates nations and nationalism within colonial relations, this article examines nationalism in settler‐colonial Taiwan amid China's colonial claim to sovereignty. Drawing on interviews, conservation documents and popular representations, we show how the Formosan black bear became a national symbol of resistance ...

The complex interaction between mammalian herbivores, climate, soil and fire has shaped the evolution and distribution of plant spinescence across biogeographical realms

New Phytologist, EarlyView.
Evolution of spinescence in mimosoid legumes. Summary The evolutionary arms race between plants and herbivores led to numerous plant adaptations, including spinescence. However, the balance between herbivory and abiotic conditions in the evolution of spinescence remains unclear. We integrated phylogenetic, geographic, and trait data for 2686 species of

Shifts in benthic megafauna communities after glacial retreat in an Antarctic fjord

Communications Earth & Environment
Underwater imagery survey was conducted to address changes in Antarctic benthic megafauna communities by recent glacial retreat in Marian Cove, where distance from the glacier was proportional to retreat period.
