Foraging activity by the southern brown bandicoot (Isoodon obesulus) as a mechanism for soil turnover [PDF]

, 2012
Mammals that forage for food by biopedturbation can alter the biotic and abiotic characteristics of their habitat, influencing ecosystem structure and function.

Thermal Niche Differentiation Shapes the Hibernating Bat Assemblages in Bulgarian Caves Across an Elevational Gradient

Biology
Elevation is a strong proxy for the thermal environment because it causes a predictable drop in temperature and food availability. This restricts cave-dwelling bats to species with specific metabolic traits, such as torpor or migration to avoid cold ...

Secondary succession of overgrazed Pannonian sandy grasslands [PDF]

, 2008
We assessed vegetation changes on acidic sandy soils in permanent plots to follow secondary succession after cessation of intensive goose breeding in E Hungary.We also aimed to estimate the time required for vegetation regeneration and indicate ...

Tree species richness and turnover throughout New Zealand forests [PDF]

Journal of Vegetation Science, 1999
Abstract. Patterns of mortality, recruitment, and forest turnover were investigated using permanent plot data from temperate forests in 14 localities throughout New Zealand. Tree mortality and recruitment rates were calculated from tagged trees ≥ 10 cm diameter at 1.4 m on individual 400 m2 plots, and turnover rates were calculated as the mean of ...

Community dynamics of insular biotas in space and time [PDF]

, 2004
The various features determining species distributions remain enigmatic in ecology. This thesis deals with the spatial and temporal dynamics of land birds on the islands of the Dahlak archipelago, the Red Sea, and of mammals, birds and reptiles among the

Contrasting patterns of turnover between plants, pollinators and their interactions [PDF]

, 2014
Aim: Biogeographers typically assess patterns of diversity across landscapes. As interacting groups often exhibit contrasting trends, this leads to variation in the structure of interaction networks and thereby influences ecosystem processes. Here we aim

Effects of forest fragmentation on the vertical stratification of neotropical bats [PDF]

, 2020
Vertical stratification is a key component of the biological complexity of rainforests. Understanding community- and species-level responses to disturbance across forest strata is paramount for evidence-based conservation and management.

Understory plant species recruitment and expansion spur community shifts following forest restoration treatments

Ecosphere
Restoration treatments have been implemented in many of the dry conifer forests of the western United States. By decreasing forest density and increasing forest heterogeneity, these treatments are generally effective at meeting their primary objective of

High Temporal Beta Diversity in an Ant Metacommunity, With Increasing Temporal Functional Replacement Along the Elevational Gradient

Frontiers in Ecology and Evolution, 2020
Ecological communities vary considerably in space and time and understanding such changes has fundamental relevance for ecology and conservation sciences.

The biased evolution of generation time

, 2016
Many life-history traits, like the age at maturity or adult longevity, are important determinants of the generation time. For instance, semelparous species whose adults reproduce once and die have shorter generation times than iteroparous species that ...
