Reserve Size And Fragmentation Alter Community Assembly, Diversity, And Dynamics [PDF]

open access: yes, 2013
Researchers have disputed whether a single large habitat reserve will support more species than many small reserves. However, relatively little is known from a theoretical perspective about how reserve size affects competitive communities structured by ...

Varying Patterns on Varying Scales: A Metacommunity Analysis of Nematodes in European Lakes. [PDF]

open access: yesPLoS ONE, 2016
Ecological community patterns are often extremely complex and the factors with the greatest influence on community structure have yet to be identified.

Shaping research in marine functional connectivity for integrated and effective marine science and management

open access: yesBiological Reviews, EarlyView.
ABSTRACT Effective knowledge of ecological connectivity at sea and at the land–sea interface is key to supporting global policy goals to conserve and restore ocean biodiversity and function. However, a persistent lack of commonality in terminology and understanding around the concept of connectivity in marine ecological studies hampers its integration ...

Evaluating Alternative Metacommunity Hypotheses for Diatoms in the McMurdo Dry Valleys Using Simulations and Remote Sensing Data

open access: yesFrontiers in Ecology and Evolution, 2020
Diatoms are diverse and widespread freshwater Eukaryotes that make excellent microbial subjects for addressing questions in metacommunity ecology. In the McMurdo Dry Valleys of Antarctica, the simple trophic structure of glacier-fed streams provides an ...

About Commensurability of Diversity within and among Communities

open access: yesDiversity, 2023
(1) Background: Is variation among the communities of a metacommunity higher than within the communities? Community ecologists and population geneticists often characterize the structure of metacommunities by partitioning variation (diversity) into the ...

Headwaters are critical reservoirs of microbial diversity for fluvial networks [PDF]

open access: yes, 2013
Streams and rivers form conspicuous networks on the Earth and are among nature's most effective integrators. Their dendritic structure reaches into the terrestrial landscape and accumulates water and sediment en route from abundant headwater streams to a

Developing a macroecology for human‐altered ecosystems

open access: yesEcography, EarlyView.
Although anthropogenically‐induced ecological disruptions are fundamentally important in defining ecosystem properties, they are largely overlooked by macroecological theory. Anthropogenic disruptions and their effects are generally not comparable to one another, nor to disturbances that are part of natural disturbance regimes.

A comparative analysis reveals weak relationships between ecological factors and beta diversity of stream insect metacommunities at two spatial levels. [PDF]

open access: yes, 2015
The hypotheses that beta diversity should increase with decreasing latitude and increase with spatial extent of a region have rarely been tested based on a comparative analysis of multiple datasets, and no such study has focused on stream insects.

Spatial distribution of acoustic traits in bird assemblages along regional bioclimatic gradients

open access: yesEcography, EarlyView.
Environmental variation shapes acoustic interactions among birds, creating spatial structures in the sonic signature of local species assemblages. Exploring these patterns at regional scales can reveal processes that segregate acoustic strategies along environmental gradients.
