La Desigualdad en las intensidades energéticas y la composición de la producción. Un análisis para los países de la OCDE [PDF]

, 2009
Esta investigación analiza las desigualdades de las intensidades energéticas entre países de la OCDE, su evolución y sus causas. Estas intensidades constituyen uno de los principales factores determinantes de las emisiones per cápita y, por tanto, de las

Long‐term comparison shows protected and non‐protected forests differ in harvesting, but not in wildfires or drought‐driven dieback

Journal of Applied Ecology, Volume 63, Issue 2, February 2026.
Lower forest harvesting in Natura 2000 sites may align with socio‐economic barriers often claimed by local communities, but protection does not influence vulnerability to other disturbances. In a general scenario of reduced forest harvesting in the region, we argue that differences in harvesting due to protection are statistically significant but ...

Integrated demographic strategies are more strongly associated with variation in conspecific density dependence than single traits in tropical tree seedlings

Journal of Ecology, Volume 114, Issue 2, February 2026.
Species‐specific conspecific negative density dependence (CNDD) varied widely among tropical tree species. CNDD was strongest in fast‐growing species and tall, long‐lived pioneers, weakly related to most functional traits except wood density and strongest in rare species. These results show that integrated life‐history strategies explain CNDD variation

High Fluctuating Asymmetry in Birds in a Large Neotropical City

Austral Ecology, Volume 51, Issue 2, February 2026.
Urbanisation is a powerful environmental force, negatively impacting the few organisms that persist in urban areas. Here, we investigated the relationship between urbanisation intensity and Fluctuating asymmetry (FA) in birds. Our results suggest that urbanisation (even at lower intensities) may impose stronger genetic and/or environmental stress on ...

How does the silvopastoral use modify the structure and population dynamics of mixed cypress and coihue forests? [PDF]

, 2018
Los bosques mixtos de ciprés de la cordillera (Austrocedrus chilensis) y coihue (Nothofagus dombeyi) del noroeste de la Patagonia están influenciados por fuertes presiones antrópicas como el uso silvopastoril, y en los cuales no existe una planificación ...

Mitigating light pollution impacts on arthropods based on light‐emitting diode properties

Conservation Biology, Volume 40, Issue 1, February 2026.
Abstract Light pollution from artificial light at night (ALAN) is a significant environmental problem with far‐reaching consequences for ecological systems. Recent innovations in light‐emitting diode (LED) technology may offer sustainable outdoor lighting solutions, but scientific evidence is lacking. We investigated the effects of various LED lighting
