Effect of green infrastructure on restoration of pollination networks and plant performance in semi‐natural dry grasslands across Europe

Journal of Applied Ecology, Volume 61, Issue 5, Page 1015-1028, May 2024.
Our findings provide evidence of the necessity to enhance ecosystem functions while avoiding biotic homogenisation. Restoration programs should aim at increasing landscape connectivity which influences plant communities, pollinator assemblages and their interaction patterns.

El significado del éxito reproductivo en poblaciones humanas

Revista Argentina de Antropología Biológica, 2003
Para la sociobióloga, el éxito reproductivo a sido desde el principio, la medida universal del valor adaptivo. La noción es muy discutible, considerando que se trata de una estimación individual, inapropiada a evaluar el valor selectivo de un (supuesto ...

Identifying predictors of translocation success in rare plant species

Conservation Biology, Volume 38, Issue 2, April 2024.
Abstract The fundamental goal of a rare plant translocation is to create self‐sustaining populations with the evolutionary resilience to persist in the long term. Yet, most plant translocation syntheses focus on a few factors influencing short‐term benchmarks of success (e.g., survival and reproduction).

Assessing the reproductive consequences of mate retention and pair bond duration in Thorn‐tailed Rayadito (Aphrastura spinicauda), a short‐lived, socially monogamous neotropical bird

Ibis, Volume 166, Issue 2, Page 396-410, April 2024.
The adaptive value of mate retention has been studied in several socially monogamous birds but evidence of reproductive benefits for short‐lived species is inconclusive. Most studies come from northern latitudes but more research on tropical birds is needed, as these species typically show higher survival rates and longer pair bonds than those from ...
