Limited sex differences in plastic responses suggest evolutionary conservatism of thermal reaction norms: A meta-analysis in insects. [PDF]
Evol Lett, 2022 Abstract Temperature has a profound effect on the growth and development of ectothermic animals. However, the extent to which ecologically driven selection pressures can adjust thermal plastic responses in growth schedules is not well understood. Comparing temperature‐induced plastic responses between sexes provides a promising but underexploited ...

Conservation 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 ...

Functional 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.

Cuadernos salmantinos de filosofía, 2021 La experiencia de la pobreza llama a la economía a humanizarse y a la filosofía a pensar etimológicamente desde las “normas de la casa”. Se descubre, entonces, el sentido de las épocas y de las generaciones filosóficas, la razón de su fecundidad y de su pobreza, así como la relación entre estas y la justicia.

The role of cell size in shaping responses to oxygen and temperature in fruit flies
Functional 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
Conservation 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
Conservation 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).

Horizonte Médico (Lima), 2006 La endometriosis se diagnostica con frecuencia en mujeres infértiles. Es tratada a menudo por resección o ablación de las lesiones por cirugía laparoscópica; pero si ésta mejora la fertilidad, no se ha establecido. Realizamos un ensayo aleatorizado y controlado para determinar si la cirugía laparoscópica mejoró la fecundidad en mujeres infértiles con ...
