The collective application of shorebird tracking data to conservation

open access: yesConservation Biology, EarlyView.
Abstract Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership

Structured machine learning modeling to support conservation of deep‐sea benthic biodiversity

open access: yesConservation Biology, EarlyView.
Abstract Biodiversity monitoring programs need to deliver accurate, timely, and actionable predictions. To establish a predictive monitoring program for deep‐sea benthos of the Santos Basin, Brazil, we developed a two‐stage structured model that allowed comparison of biodiversity predictions obtained from environmental simulations (2M‐Sim).

New Antarctic stenothoids sensu lato (Amphipoda, Crustacea)

open access: yes, 2011
Three stenothoid species are reported from recent Antarctic collections. Two of these are new to science (Prometopa cedrici sp. nov. and Antatelson claudei sp. nov.). A few character states of Antatelson walkeri are discussed.

Overlap of nonbreeding wandering albatrosses with fisheries and implications for colony‐specific population trajectories at South Georgia

open access: yesConservation Biology, EarlyView.
Abstract Bycatch in fisheries is one of the most serious threats to pelagic seabirds, causing major population declines. Mitigation measures can reduce bycatch substantially, but many fisheries fail to apply best practices, and seabird mortality remains high.

Global distribution of aquatic animal telemetry effort reveals geographic biases and opportunities for more inclusive tracking studies

open access: yesConservation Science and Practice, EarlyView.
Despite broad global distribution of aquatic telemetry studies, important biogeographic regions remain poorly investigated. The most important variables correlated with the distribution of telemetry studies were political stability, conservation funding, number of scientific documents, and English as a first language.

Discovery of a cryptic aminoacidic triad involved in the temperature adaptation of GH1 enzymes

open access: yesThe FEBS Journal, EarlyView.
Cold‐active enzymes retain high catalytic activity at low temperatures but are characterized by thermal instability, a behavior not fully understood. Comparison between a cold‐active GH1 and its mesophilic counterparts highlights the role of a three‐residue motif (W‐M‐F) in conferring structural stability to a mesophilic GH1.

Expansion of invasive carabids across elevation and habitats on sub‐Antarctic South Georgia

open access: yesInsect Conservation and Diversity, EarlyView.
Two introduced carabid species have continued to expand their ranges on the sub‐Antarctic island of South Georgia over the past 10–15 years. The species have colonised inland valleys and are present across habitats but are more abundant in those with high vegetation cover. N‐mixture models revealed the optimal sampling method, intensity and habitat for
