Spatial distribution patterns and movements of Holothuria arguinensis in the Ria Formosa (Portugal) [PDF]

open access: yes, 2015
Holothurian populations are under pressure worldwide because of increasing demand for beche-de-mer, mainly for Asian consumption. Importations to this area from new temperate fishing grounds provide economic opportunities but also raise concerns ...

Energy Landscapes and the Landscape of Fear [PDF]

open access: yes, 2016
Animals are not distributed randomly in space and time because their movement ecology is influenced by a variety of factors. Energy landscapes and the landscape of fear have recently emerged as largely independent paradigms, both reshaping our ...

Temperature and microclimate refugia use influence migratory timings of a threatened grassland bird

open access: yesMovement Ecology, 2023
Background Seasonal changes in resource availability are known to influence the migratory behaviour of animals, including both timing and distance. While the influence of environmental cues on migratory behaviour has been widely studied at the population

Apparent competition drives community-wide parasitism rates and changes in host abundance across ecosystem boundaries [PDF]

open access: yes, 2016
Species have strong indirect effects on others, and predicting these effects is a central challenge in ecology. Prey species sharing an enemy (predator or parasitoid) can be linked by apparent competition, but it is unknown whether this process is strong

Key Questions in Marine Megafauna Movement Ecology. [PDF]

open access: yesTrends in Ecology & Evolution, 2016
It is a golden age for animal movement studies and so an opportune time to assess priorities for future work. We assembled 40 experts to identify key questions in this field, focussing on marine megafauna, which include a broad range of birds, mammals, reptiles, and fish.

Inferring the rules of social interaction in migrating caribou [PDF]

open access: yes, 2018
Social interactions are a significant factor that influence the decision-making of species ranging from humans to bacteria. In the context of animal migration, social interactions may lead to improved decision-making, greater ability to respond to ...

Ecohydraulics exemplifies the emerging “paradigm of the interdisciplines” [PDF]

open access: yes, 2016
The basic premise underlying ecohydraulics is deceptively simple: create a new discipline focused on the effects of water movement in aquatic ecosystems by melding principles of aquatic ecology (including aspects of fluvial geomorphology) and engineering

Radionuclide movement in an ecological chain

open access: yesEcotoxicology and Environmental Safety, 1978
Abstract Radioactive substances create a considerable hazard, as they move through the environment of man and form an ecological chain. The first link of this chain is atmosphere; the next links are formed by water, soil, plants and animals. At the end of the chain is man.

Acoustic evaluation of behavioral states predicted from GPS tracking: a case study of a marine fishing bat

open access: yesMovement Ecology, 2019
Background Multiple methods have been developed to infer behavioral states from animal movement data, but rarely has their accuracy been assessed from independent evidence, especially for location data sampled with high temporal resolution.
