A Trophic and Non‐Trophic Seasonal Interaction Network Reveals Potential Management Units and Functionally Important Species

open access: yesGlobal Ecology and Biogeography, Volume 34, Issue 1, January 2025.
ABSTRACT Aim Understanding the organisation of the wide variety of ecological interactions is crucial to advancing our understanding and management of real ecosystems. We aimed to compile a ‘complete’ network of tetrapod trophic and non‐trophic interactions for the entire North American boreal forest biome that could be analysed to gain insights into ...

Montado’s ecosystem functions and services: the case study of Alentejo Central – Portugal [PDF]

open access: yes, 2017
Although the concept of ecosystem services is well defined and centred on human use of natural systems, it is not yet consensual. The ecosystem services connect ecology and economy; they allow to integrate ecology into policies and to bring a monetary ...

Migration mortality in birds

open access: yesIbis, Volume 167, Issue 1, Page 106-123, January 2025.
Bird migration is one of the greatest wildlife spectacles, producing massive global changes in the distributions of birds twice each year. To understand the evolution of this phenomenon, it is important to know the costs of these journeys in terms of the mortality they impose.

A systematic literature review investigating the association between biodiversity and beaver lodges

open access: yesMammal Review, Volume 55, Issue 1, January 2025.
Bar graph categorised into the animal groups, with each icon representing a species that was recorded interacting with beaver lodges from the final dataset of articles (n = 35). Abstract The positive relationship between biodiversity and beaver‐modified habitats such as ponds, dams, and canals has been demonstrated; however, the association between ...

Shorebird Habitat Use and Nest-site Selection in the Playa Lakes Region [PDF]

open access: yes, 2005
Wetlands in the Playa Lakes Region (PLR) provide important habitats for wintering waterfowl, cranes, and both migrant and breeding shorebirds. Playa Lakes Region wetlands experience naturally fluctuating hydroperiods but are exposed to anthropogenic ...

A Tool for Rapid Assessment of Hydrological Connectivity Patterns in Texas Coastal Wetlands: Linkages between Tidal Creeks and Coastal Ponds

open access: yesTexas Water Journal, 2019
Coastal salt marshes are heterogeneous, spatially complex ecosystems. The degree of hydrological connectivity in these systems can be a significant driver in the flux of energy, organisms, and nutrients across the marsh landscape.

Regional evolutionary distinctiveness and endangerment as a means of prioritizing protection of endangered species [PDF]

open access: yes, 2015
Conservation is costly, and choices must be made about where to best allocate limited resources. I propose a regional evolutionary diversity and endangerment (RED-E) approach to prioritization of endangered species.

Isotopic ordering in eggshells reflects body temperatures and suggests differing thermophysiology in two Cretaceous dinosaurs [PDF]

open access: yes, 2015
Our understanding of the evolutionary transitions leading to the modern endothermic state of birds and mammals is incomplete, partly because tools available to study the thermophysiology of extinct vertebrates are limited.
