Hidden demographic impacts of fishing and environmental drivers of fecundity in a sea turtle population

open access: yesConservation Biology, Volume 37, Issue 5, October 2023., 2023
Abstract Fisheries bycatch is a critical threat to sea turtle populations worldwide, particularly because turtles are vulnerable to multiple gear types. The Canary Current is an intensely fished region, yet there has been no demographic assessment integrating bycatch and population management information of the globally significant Cabo Verde ...

Precipitation timing and soil substrate drive phenology and fitness of Arabidopsis thaliana in a Mediterranean environment

open access: yesFunctional Ecology, Volume 37, Issue 9, Page 2471-2487, September 2023., 2023
Read the free Plain Language Summary for this article on the Journal blog. Abstract In Mediterranean climates, the timing of seasonal rains determines germination, flowering phenology and fitness. As climate change alters seasonal precipitation patterns, it is important to ask how these changes will affect the phenology and fitness of plant populations.

The role of cell size in shaping responses to oxygen and temperature in fruit flies

open access: yesFunctional Ecology, Volume 37, Issue 5, Page 1269-1279, May 2023., 2023
Read the free Plain Language Summary for this article on the Journal blog. Abstract The body size of an animal is strongly coupled to key ecological traits such as fecundity, mortality and growth. Ectothermic animals mature at smaller body sizes in warmer conditions and under low oxygen availability (hypoxia).

Bridging gaps in demographic analysis with phylogenetic imputation

open access: yesConservation Biology, Volume 35, Issue 4, Page 1210-1221, August 2021., 2021
Abstract Phylogenetically informed imputation methods have rarely been applied to estimate missing values in demographic data but may be a powerful tool for reconstructing vital rates of survival, maturation, and fecundity for species of conservation concern.

Combined effects of life‐history traits and human impact on extinction risk of freshwater megafauna

open access: yesConservation Biology, Volume 35, Issue 2, Page 643-653, April 2021., 2021
Abstract Megafauna species are intrinsically vulnerable to human impact. Freshwater megafauna (i.e., freshwater animals ≥30 kg, including fishes, mammals, reptiles, and amphibians) are subject to intensive and increasing threats. Thirty‐four species are listed as critically endangered on the International Union for Conservation of Nature (IUCN).

High dispersal ability is related to fast life‐history strategies

open access: yesJournal of Ecology, Volume 106, Issue 4, Page 1349-1362, July 2018., 2018
Dispersal has been largely neglected in comparative demographic studies, despite its pivotal importance for populations. Our explicit incorporation of dispersal in a comparative life‐history framework provides key insights to bridge the gap between dispersal ecology and life‐history traits. Species with fast life‐history strategies disperse their seeds
