(Springer, 2015)Forestry plantations supporting native species exhibit a dense understory, which might reduce bat activity within plantations. We compared bat activity in Monterrey pine plantations with and without an understory in ...
-
(Springer, 2012)Intraspecific variation in sociality is thought to reflect a trade-off between current fitness benefits and costs that emerge from individuals' decision to join or leave groups. Since those benefits and costs may be ...
-
(BLACKWELL, 2006-02)Aim To integrate the effects of ecosystem engineers (organisms that create, maintain or destroy habitat for other species) sharing the same archetype on species diversity, and assess whether different engineer species have ...
-
(BLACKWELL, 2007-07)1. Ecosystem engineers are organisms that change abiotic conditions in ways that affect the performance and distribution of other species, including exotics. Several mechanisms have been proposed for the successful ...
-
(ELSEVIER, 2006-03-01)Forest edges have been long recognized as the first landscape elements to be invaded by alien plant species in forest ecosystems. However, little is known about the role of forest edge type in invasive species patterns. ...
-
(Sociedad de Biología de Chile, 2008-06)El flujo de entrada de nitrógeno (N) en ecosistemas de bosques templados de la Isla de Chiloé puede ocurrir en una proporción importante vía fijación no simbiótica (FNS). Debido a que este proceso es llevado a cabo por ...
-
EFFECT OF DENSITY AND FLOWER SIZE ON THE REPRODUCTIVE SUCCESS OF NOTHOSCORDUM GRAMINUM (ALLIACEAE) (2006)The size, form and color are signals used by flowers to attract their pollinators. Large and showy color flowers usually receive higher pollinators visitation rates. According to the optimal forage theory, pollinators would ...
-
(Springer, 2016)For polyandrous species where females have sperm storage structures, males develop several strategies to avoid sperm competition and thus to maximize the number of eggs fertilized. On the other hand, females may receive ...
-
(ELSEVIER, 2006-04)North American beavers (Castor canadensis) were introduced into southern South America in 1946. Since that time, their populations have greatly expanded. In their native range, beavers shape riparian ecosystems by selectively ...
-
(Amer Soc Cell Biology, 2015)ABSTRACT Kinesin-5 is a slow homotetrameric motor protein best known for its essential role in the mitotic spindle, where it limits the rate at which faster motors can move microtubules. In neurons, experimental suppression ...
-
(Taylor & Francis, 2015)The endocranial anatomy of Pygoscelis calderensis, a fossil species from the Bahı´a Inglesa Formation (Middle Miocene– Pliocene) of Chile, South America, was described through CT scans. Reconstructions of the fossil P. ...
-
(Springer, 2015)The extreme sexual size dimorphism in spiders has motivated studies for many years. In many species the male can be very small relative to the female. There are several hypotheses trying to explain this fact, most of ...
-
(Wiley-Blackwell, 2015)Interannual variability in climatic conditions should be taken into account in climate change studies in semi-arid ecosystems. It may determine differentiation in phenotypic plasticity among populations, with populations ...
-
(GAUTHIER-VILLARS/EDITIONS ELSEVIER, 2006-09)Unfavorable temperatures and weather conditions for biotic pollination in above-tree-line alpine habitats predict self-compatibility, high levels of autogamy and small flower size ("autogamy reproductive assurance hypothesis"), ...
-
(Universidad Nacional Autónoma de México, Jiménez Editores, 2005)
-
(Wiley, 2022)Investigating whether mating patterns are biased in relation to kinship in isolated populations can provide a better understanding of the occurrence of inbreeding avoidance mechanisms in wild populations. Here, we report ...
-
(Elsevier, 2016)Mediterranean-type climate (MTC) ecosystems are characterized by recurrent wildfires. Although the majority of wildfires are human-ignited, non-anthropogenic (Le., natural) wildfires are common in all MTC regions except ...
-
(Oxford University Press, 2020)Over evolutionary time, pathogen challenge shapes the immunepheno type of the host to better respond to an incipient threat. The extent and direction of this selection pressure depend on the local pathogen composition, ...
