Ecology and Evolution, Volume 16, Issue 9, September 2026.We investigated ontogenetic variation in diet composition of the Amur softshell turtle (Pelodiscus maackii) from a temperate large‐river system using stomach content analyses of field‐collected individuals. Dietary composition differed markedly across body‐size classes, indicating pronounced ontogenetic trophic differentiation and shifts in resource ...

Dietary partitioning mediates species coexistence in the high seas area of northwest Pacific
Ecography, Volume 2026, Issue 9, September 2026.Niche partitioning, manifesting along various axes of the ecological niche, is a fundamental mechanism mediating species coexistence in a system. However, the emergence of many species in marine ecosystems would face considerable constraints in achieving coexistence through spatiotemporal differentiation mechanisms under the framework of niche ...

Invasive mammals disrupt sea–land nutrient inputs over 169 years on subtropical oceanic islands
Ecosphere, Volume 17, Issue 9, September 2026.Abstract Invasive mammals have severely impacted oceanic islands, reducing or extirpating seabird populations and driving the collapse of nutrient flows with lasting ecosystem effects. We investigated these dynamics on contrasting subtropical oceanic islands in the South Pacific: Rangitāhua, a large island where goats, cats, and rats caused the ...

Knowledge gaps and areas for synthesis in experimental studies of context‐dependent predation risk
Ecology, Volume 107, Issue 9, September 2026.Abstract A growing number of experimental studies address whether the anti‐predator trait responses of prey are associated with costs to prey fitness (non‐consumptive effects) or to the fitness of other species (trait‐mediated indirect effects). Because ecologists remain keen to determine when these risk effects matter, there is a need to know how much

First Report on the Diet of the Angolan Flying Squid (Todarodes angolensis) in New Zealand Waters
New Zealand Journal of Zoology, Volume 53, Issue 3, September 2026.The Angolan flying squid (Todarodes angolensis) is a southerly distributed, large‐bodied ommastrephid preyed upon by many large marine vertebrates such as the southern elephant seal and deep‐sea squalid sharks. Here, we report its diet in New Zealand waters for the first time, identifying prey items from the stomach contents of 58 adults using ...

Thermal Preference and Performance in the Marine Amphipod Melita inaequistylis
New Zealand Journal of Zoology, Volume 53, Issue 3, September 2026.Climate‐induced warming can impose thermal stress on organisms, impacting their physiology in addition to ecosystem structure and functioning. In most species the response to warming is poorly understood; the majority of thermal physiology research focuses on single performance measures and fails to predict overall functioning with respect to future ...

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.This study provides the first global systematic synthesis of Cryptosporidium spp. infection in snakes. A pooled prevalence of 12.6% was identified, with higher occurrence in captive‐associated populations than in wild snakes. Eight Cryptosporidium species, including multiple zoonotic taxa, were reported, underscoring the potential role of snakes within
