El concepto de nicho en las metacomunidades
Ecología Austral, 2005 La ciencia de la ecología estudia las interacciones de los sistemas biológicos con el medio ambiente. El concepto de nicho ecológico es la base central de este estudio ya que describe cómo organismos en diferentes niveles de organización interactúan con

When is the bait worth the risk? A mechanistic model of a compensatory ecological trap in seabirds
Functional Ecology, Volume 40, Issue 11, Page 3398-3421, November 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecological traps occur when organisms preferentially select habitats that reduce fitness. In seabird–fishery systems, fishery‐derived trophic subsidies can increase foraging success, reinforce habitat preference and indirectly enhance reproductive output or recruitment,

¿Nicho, teoría neutral, o una alternativa emergente?
Ecología Austral, 2010 Uno de los temas de mayor interés en Ecología ha sido predecir y entender la diversidad y la composición específica de la comunidad en el espacio y el tiempo. A lo largo de la historia se han propuesto dos modelos: el de diferenciación de nichos, basado

Journal of Animal Ecology, Volume 95, Issue 9, Page 1586-1597, September 2026.This paper argues that variation among individuals—not just species differences—can shape the sensitivity, robustness and resilience of plant–pollinator communities under global change. By linking individual traits and interaction structure to network dynamics, it provides a new framework and future research directions for predicting community ...

Latitudinal phytoplankton distribution and the neutral theory of biodiversity [PDF]
, 2012 Aim Recent studies have suggested that global diatom distributions are not limited by dispersal, in the case of both extant species and fossil species, but rather that environmental filtering explains their spatial patterns.

Revista Chilena de Historia Natural, 2010 Until now, there are three evolutionary models: I) The Synthetic Theory of Evolution (STE) also named as the Neo-Darwinian model; II) The Neutral Theory of Evolution (NTE) with its daughter the Nearly-Neutral Theory of Evolution (NNTE); III) The Theory ...

American Anthropologist, Volume 128, Issue 3, Page 494-510, September 2026.ABSTRACT The evolutionary study of human dispersal is a key topic in biological anthropology. However, recent research has revealed inconsistencies between molecular and anatomical data across different timescales and geographic regions. Despite increased interdisciplinary dialogue, these discordances are rarely analyzed in depth or interpreted for ...
