Interactive effects of body mass changes and species‐specific morphology on flight behavior of chick‐rearing Antarctic fulmarine petrels under diurnal wind patterns

Ecology and Evolution, 2021
For procellariiform seabirds, wind and morphology are crucial determinants of flight costs and flight speeds. During chick‐rearing, parental seabirds commute frequently to provision their chicks, and their body mass typically changes between outbound and

Stabilizing effects of group formation by Serengeti herbivores on predator-prey dynamics

Frontiers in Ecology and Evolution, 2022
Predator-prey theory often assumes that potential prey individuals are solitary and evenly distributed in space. This assumption is violated in social, mobile prey, such as many ungulates.

Productive foraging grounds enhance maternal condition and offspring quality in a capital breeding species

Ecology and Evolution
Feeding ecology is an essential component of an organism's life, but foraging comes with risks and energetic costs. Species in which populations exhibit more than one feeding strategy, such as sea turtles, are good systems for investigating how feeding ...

Habitat change at a multi-species goose breeding area on Southampton Island, Nunavut, Canada, 1979–2010

Arctic Science, 2020
Foraging by hyperabundant Arctic-nesting geese has significant impacts on vegetation of Arctic and subarctic coastal lowlands, but long-term data sets documenting these changes are rare. We undertook intensive surveys of plant communities at East Bay and

Connection of mobility and foraging - A cross-cultural analysis

Etnoantropološki Problemi, 2007
The goal of this inquiry is to explore the existence and severity of the liaison in-between mobility and cattle breeding. The author has decided to test the hypothesis of a relation between mobility and cattle breading through quantitative analysis of a

Fueling Defense: Effects of Resources on the Ecology and Evolution of Tolerance to Parasite Infection

Frontiers in Immunology, 2018
Resource availability is a key environmental constraint affecting the ecology and evolution of species. Resources have strong effects on disease resistance, but they can also affect the other main parasite defense strategy, tolerance. A small but growing

High Ambient Temperatures Are Associated With Reduced Foraging Capacity in an Equatorial Mammal, the Banded Mongoose (Mungos mungo)

Ecology and Evolution
Due to anthropogenic climate change, there is substantial interest in how temperature variation impacts reproduction and survival in animal populations; however, the underlying mechanisms are often poorly understood.

Feeding Behavior and Host Plant Preferences of Episyrphus balteatus‎ (DeGeer) ‎ and Ischiodon scutellaris ‎(Fabricius) ‎ in Southern Punjab, Pakistan

Kufa Journal for Agricultural Sciences
During the present study, 300 adults along with 30 larvae of Episyrphus balteatus and 212 adults along with 25 larvae of Ischiodon scutellaris were collected from 15 and 13 host plants, respectively from Bahawalpur, Southern Punjab, Pakistan. The adults

Ray bioturbation rates suggest they shape estuary processes

Remote Sensing in Ecology and Conservation
Bioturbation of sediments is a key ecosystem service in estuarine and marine ecosystems, and rays (superorder Batoidea: skates, stingrays, electric rays and shovelnose rays) are among the largest bioturbators, modifying their habitat through foraging and

The Use of Sound Recorders to Remotely Measure Grass Intake Behaviour in Horses

Animals
Visual observation to record grass intake is time-consuming and labour-intensive. Technological methods, such as activity monitors, have been used but only record head position.
