Value of combining transect counts and telemetry data to determine short‐term population trends in a globally threatened species

Conservation Biology, Volume 37, Issue 6, December 2023., 2023
Abstract To evaluate conservation interventions, it is necessary to obtain reliable population trends for short (<10 years) time scales. Telemetry can be used to estimate short‐term survival rates and is a common tool for assessing population trends, but it has limitations and can be biased toward specific behavioral traits of tagged individuals ...

Berries and bullets: influence of food and mortality risk on grizzly bears in British Columbia Bayas y balas: influencia de la alimentación y el riesgo de mortalidad en los osos grizzly en la Columbia Británica Des baies et des balles: influence de l'alimentation et risques de mortalité chez les ours grizzlys de la Colombie‐Britannique

Wildlife Monographs, Volume 213, Issue 1, November 2023., 2023
We developed a spatialized surface for the primary food of grizzly bears in southeast British Columbia. After using this huckleberry patch layer to model habitat selection, fitness, and density, in a bottom‐up top‐down paradigm, we found that huckleberry patches near forestry roads contribute very little to fitness and density.

Tracking marine tetrapod carcasses using a low‐cost mixed methodology with GPS trackers, passive drifters and citizen science

Methods in Ecology and Evolution, Volume 14, Issue 9, Page 2354-2361, September 2023., 2023
Abstract Drift experiments are essential to understand stranding patterns and estimate the mortality of beached animals. Most studies do not use telemetry technology due to the high costs of this methodology. The objective of this paper is to describe the possibilities of tracking marine tetrapod carcasses with a low‐cost and replicable methodology ...

Using historical spy satellite photographs and recent remote sensing data to identify high‐conservation‐value forests

Conservation Biology, Volume 36, Issue 2, April 2022., 2022
Abstract High‐conservation‐value forests (HCVFs) are critically important for biodiversity and ecosystem service provisioning, but they face many threats. Where systematic HCVF inventories are missing, such as in parts of Eastern Europe, these forests remain largely unacknowledged and therefore often unprotected.

Near‐term ecological forecasting for dynamic aeroconservation of migratory birds

Conservation Biology, Volume 35, Issue 6, Page 1777-1786, December 2021., 2021
Abstract Near‐term ecological forecasting has the potential to mitigate negative impacts of human modifications on wildlife by directing efficient action through relevant and timely predictions. We used the U.S. avian migration system to highlight ecological forecasting applications for aeroconservation.

Identifying the possibilities and pitfalls of conducting IUCN Red List assessments from remotely sensed habitat information based on insights from poorly known Cuban mammals

Conservation Biology, Volume 35, Issue 5, Page 1598-1614, October 2021., 2021
Abstract The International Union for Conservation of Nature's Red List of Threatened Species (RLS) is the key global tool for objective, repeatable assessment of species’ extinction risk status, and plays an essential role in tracking biodiversity loss and guiding conservation action.

Strongly directional and differential swimming behavior of an adult female white shark, Carcharodon carcharias (Chondrichthyes: Lamnidae) from Guadalupe Island, Mexico

Latin American Journal of Aquatic Research, 2015
We report on an adult female white shark tracked for 288 days and 7,100 km in the NE Pacific Ocean. The shark, tagged with a real-time satellite tag off Guadalupe Island, Mexico in October 2006, remained around the island for 3.5 months but left in early

Protecting biodiversity and economic returns in resource‐rich tropical forests

Conservation Biology, Volume 35, Issue 1, Page 263-273, February 2021., 2021
Abstract In pursuit of socioeconomic development, many countries are expanding oil and mineral extraction into tropical forests. These activities seed access to remote, biologically rich areas, thereby endangering global biodiversity. We examined how protection of biodiversity and economic revenues can be balanced in biologically valuable regions ...
