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 ...

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
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
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
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).

Este artículo examina críticamente la interpretación del Laocoonte como una obra cuyo principal aporte consiste en una teoría de los signos. Dos elementos del texto de Gotthold Ephraim Lessing son destacados: la especificidad de la dinámica temporal que despliegan las imágenes estáticas y la defensa que el autor hace del potencial icónico del lenguaje.

Fecundidad de Hemigrammus hyanuary [PDF]
Título en ingles: Fecundity of Hemigrammus hyanuaryTítulo en portugués: Fecundidade de hyanuary de Hemigrammus Resumen: El conocimiento sobre la cantidad de huevos que una hembra es capaz de desovar en cada oportunidad reproductiva (fecundidad absoluta), es de gran importancia, pues de él depende el cálculo de las potencialidades reproductivas de la ...

High dispersal ability is related to fast life‐history strategies
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
