Machine and deep learning approaches to understand and predict habitat suitability for seabird breeding. [PDF]

Ecol Evol, 2023
Understanding seabird breeding habitat selection and suitability is often complex due to the integration of land and sea features across multiple spatial scales. A complementarity approach between convolutional neural network (CNN) and random forest (RF) models was applied to predict and explain the selection pattern of tropical larids breeding ...

Characterizing Diet of the Least Tern <i>Sternula antillarum</i> using DNA Metabarcoding

Marine Ornithology
A complete picture of diet composition is an essential element to understanding the ecological role of organisms. Moreover, diet studies can serve as an important tool for monitoring species and changes to the food web. One method to provide resolution when studying the diet of avian species is DNA metabarcoding of fecal samples. As such, we used DNA

Avian eggshell thickness in relation to egg morphometrics, embryonic development, and mercury contamination. [PDF]

Ecol Evol, 2020
We measured eggshell thickness at the egg equator and the egg poles for 12 avian species, and related eggshell thickness to egg morphometrics, embryonic development, egg status, and mercury contamination. Our study also provides a review of all existing eggshell thickness data for these 12 species.

Applying cumulative effects to strategically advance large-scale ecosystem restoration. [PDF]

Front Ecol Environ, 2020
International efforts to restore degraded ecosystems will continue to expand over the coming decades, yet the factors contributing to the effectiveness of long‐term restoration across large areas remain largely unexplored. At large scales, outcomes are more complex and synergistic than the additive impacts of individual restoration projects.

Interspecies conflict, precarious reasoning, and the gull problem in the Gulf of Maine. [PDF]

Conserv Biol
Abstract Contemporary conservation science requires mediating conflicts among nonhuman species, but the grounds for favoring one species over another can be unclear. We examined the premises through which wildlife managers picked sides in an interspecies conflict: seabird conservation in the Gulf of Maine (GOM).

A case study of sea and shorebird breeding recovery following goat and cat eradication on Klein Curaçao, southern Caribbean

Journal of Field Ornithology, 2023
Here, we document major seabird breeding recovery on a satellite island of Curaçao in the southern Caribbean following the removal of goats in 1997, significant reforestation from 2000–2005, and the extermination of cats in 2001. The only seabird to have

The need for constructing endangered fish habitats that conform to climate‐driven flow changes in a western U.S. river

JAWRA Journal of the American Water Resources Association, Volume 59, Issue 5, Page 1084-1098, October 2023., 2023
Abstract Warmwater fish habitat in the San Juan River of the southwestern United States has been reduced by over 30% as a result of water depletion, reservoir inundation, and cold‐water dam releases combined with drought‐related changes in hydrology.

Conspecific density and habitat quality affect breeding habitat selection: Support for the social attraction hypothesis

Ecosphere, Volume 14, Issue 5, May 2023., 2023
Abstract Breeding habitat selection is a critical component of the annual cycle because of its effect on fitness. Multiple theories of habitat selection can be differentiated by their responses to the quantity of habitat, conspecific density, and habitat quality.

Sound‐Side Inundation and Seaward Erosion of a Barrier Island During Hurricane Landfall

Journal of Geophysical Research: Earth Surface, Volume 128, Issue 1, January 2023., 2023
Abstract Barrier islands are especially vulnerable to hurricanes and other large storms, owing to their mobile composition, low elevations, and detachment from the mainland. Conceptual models of barrier‐island evolution emphasize ocean‐side processes that drive landward migration through overwash, inlet migration, and aeolian transport. In contrast, we
