Reproductive declines in an endangered seabird: cause for concern or signs of conservation success? [PDF]

PLoS ONE, 2011
Collection and analysis of demographic data play a critical role in monitoring and management of endangered taxa. I analyzed long-term clutch size and fledgling productivity data for California least tern (Sternula antillarum browni), a federally ...

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 ...

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).

Lessons from the Tōhoku tsunami: A model for island avifauna conservation prioritization. [PDF]

Ecol Evol, 2017
We describe tsunami inundation of four islands within the largest conservation area in the United States following the 11 March 2011 earthquake off the Tōhoku coast of Japan. The extent of sudden flooding ranged from 21% to 100% of island area, occurred at night during the peak of nesting for 14 species.

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.
