Minimal Sample, Maximum Insight: DNA Metabarcoding Uncovers the Diet of Endangered Dholes in Central India

open access: yesEnvironmental DNA, Volume 8, Issue 3, May–June 2026.
We evaluated the efficiency of a minimal sampling approach for DNA metabarcoding and developed a novel single‐amplicon workflow. Using fecal DNA, we identified vertebrate prey and characterized spatio‐temporal variation in the diet of the endangered dhole (also known as Asiatic wild dog, Cuon alpinus) in central India.

Individual variation in perceived density of conspecifics and its impacts on the realization of ecological niches

open access: yesOikos, Volume 2026, Issue 5, May 2026.
Animals gather information about their surroundings, including their social environment, using a wide range of sensory modalities. Variation in reception, processing and interpretation of information (cues or signals) can lead to differences in how individuals perceive their local environment. Yet, how individual differences in environmental perception

Kick Out The Ants: A Novel and Striking Behavior in Ant-Wasp Interactions

open access: yesSociobiology, 2017
Trophobiosis between ants and homopterans is widely known. Nevertheless, this interaction can also happen between treehoppers and other animals in a non-mutualistic way.

Intercolony and Intra‐Annual Variations in Isotopic Niche of Red‐Footed Boobies Sula sula in the Tropical Indian Ocean

open access: yesEcological Research, Volume 41, Issue 3, May 2026.
We compared the diet and assessed geographic and seasonal variations in the isotopic niches of red‐footed boobies across three Indian Ocean atolls. Our results demonstrate plasticity in both diet and trophic niche, likely driven by local environmental conditions, breeding stages, and colony‐specific factors.

Scent Deterrence to Reduce Southern Flying Squirrel Kleptoparasitism of Red-Cockaded Woodpecker Cavities

open access: yesHuman-Wildlife Interactions, 2017
When establishing new populations of endangered red-cockaded woodpeckers (RCW; Picoides borealis), cavity kleptoparasites can pose a considerable obstacle to successful restoration.

Severe Population Decline of Great Skua Stercorarius skua Following a HPAI Outbreak Reflected in Migration Counts

open access: yesMarine Ecology, Volume 47, Issue 3, May/June 2026.
ABSTRACT The H5N1 avian influenza (HPAI) outbreak that began in 2021 has led to widespread mortality in birds and mammals globally, significantly impacting seabird populations. This study examines the changes in the number of migratory great skuas (Stercorarius skua), a species particularly vulnerable due to its kleptoparasitic behavior and reliance on

ETHOGRAM OF THE COMMON BEHAVIOR OF Quiscalus mexicanus (PASSERIFORMES: ICTERIDAE) IN THE REPUBLIC OF PANAMA

open access: yesTecnociencia, 2022
In this study, the behavior of Q. mexicanus was recorded through observations from July to October 2020. The observations period was from 7:00 to 10:00 a.m. and from 2:00 a.m. at 5:00 p.m. Eastern Time (ET). During this study we were able to describe 29

Intraspecific kleptoparasitism in the Cattle Egret

open access: yesJournal of Field Ornithology, 2002
Abstract Optimal foraging theory predicts that individuals should resort to kleptoparasitizing food when the net energy obtained from this behavior is greater than that gained from searching for food conventionally. We studied kleptoparasitism in the Cattle Egret (Bubulcus ibis) in southwestern Spain. Intraspecific kleptoparasitism in Cattle Egrets was

Dynamical Behavior of Two Predators–One Prey Model with Kleptoparasitism and Anti-Predator

open access: yesJournal of Physics, Conference Series
This research aims to build a mathematical model equation between one prey and two predators by combining the effects of biological phenomena such as predator strategies in obtaining food from other animals and the prey’s self-defence efforts through ...

Potential kleptoparasitism-scavenging interactions between crabs and shell-boring gastropods feeding on bivalve prey: a global survey

open access: yes, 2020
Shell-boring gastropod molluscs and crabs are important predators of many bivalve molluscs, and impact bivalve populations and food webs. When gastropods and crabs target the same bivalve prey, complex interactions between them arise that mediate their ...
