Species sorting drives variation of boreal lake and river macrophyte communities [PDF]

open access: yes, 2015
Metacommunity paradigms are increasingly studied to explain how environmental control and spatial patterns determine variation in community composition. However, the relative importance of these patterns on biological assemblages among different habitats

The disruption of seed dispersal networks: disentangling the effects of habitat loss and fragmentation

open access: yesOikos, EarlyView.
Seed dispersal by frugivores is a central process linking plant reproduction, animal foraging, population persistence, and ecosystem resilience. Currently, the spatial template sustaining these interactions is rapidly reconfigured by habitat loss and fragmentation promoted by human activity.

Amphibian Metacommunity Responses to Agricultural Intensification in a Mediterranean Landscape

open access: yesLand, 2021
Agricultural intensification has been associated with biodiversity declines, habitat fragmentation and loss in a number of organisms. Given the prevalence of this process, there is a need for studies clarifying the effects of changes in agricultural ...

Coexistence of specialist and generalist species is shaped by dispersal and environmental factors [PDF]

open access: yes, 2014
Disentangling the mechanisms mediating the coexistence of habitat specialists and generalists has been a long-standing subject of investigation. However, the roles of species traits and environmental and spatial factors have not been assessed in a ...

Using a social‐ecological macrosystems framework to understand how human activities alter ecological synchrony

open access: yesPeople and Nature, EarlyView.
Abstract Different aspects of ecological systems, biotic or abiotic, often fluctuate in coordinated patterns over space and time. Such high concordance between ecological processes is often referred to as ecological synchrony. Human activities, including and beyond climate change, have the potential to alter ecological synchrony by disrupting or ...

Temporal community change in stream ecosystems varies by assemblage across US climates

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecosystem properties are temporally dynamic. Temporal variability has been shown to decrease with increasing levels of biological organization (i.e. from population to community and ecosystem levels).

Structure and Dynamics of the Breast Tissue Microbiomes Under Tumor Influences: An Approach With Neutral, Near-Neutral, and Niche-Neutral Hybrid Models

open access: yesFrontiers in Microbiology, 2021
The structure and dynamics of breast tissue bacteria can have far-reaching influences on women’s health, particularly on breast tumor development. However, there is little understanding on the ecological processes that shape the structure and dynamics of

Dirichlet multinomial mixtures: generative models for microbial metagenomics [PDF]

open access: yes, 2012
We introduce Dirichlet multinomial mixtures (DMM) for the probabilistic modelling of microbial metagenomics data. This data can be represented as a frequency matrix giving the number of times each taxa is observed in each sample.

A Bayesian classification model to reconstruct lifetime movement patterns of riverine fish using environmental tracers

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Environmental tracers, including both elemental concentrations and isotope ratios, are widely used to reconstruct the movement patterns of animals throughout landscapes. The methodology involves creating a map that describes the distribution of the environmental tracer across the landscape, an isoscape and then matching the values of the same ...
