Restoring the fire–grazing interaction promotes tree–grass coexistence by controlling woody encroachment

open access: yesEcosphere, 2020
Woody encroachment can convert grasslands and savannas to shrublands and woodlands, so understanding the processes which regulate woody encroachment is necessary to conserve or restore these ecosystems.

Experimental Entanglement Concentration and Universal Bell-state Synthesizer [PDF]

open access: yes, 2002
We report a novel Bell-state synthesizer in which an interferometric entanglement concentration scheme is used. An initially mixed polarization state from type-II spontaneous parametric down-conversion becomes entangled after the interferometric ...

Local and landscape environmental heterogeneity drive ant community structure in temperate seminatural upland grasslands

open access: yesEcology and Evolution, 2023
Environmental heterogeneity is an important driver of ecological communities. Here, we assessed the effects of local and landscape spatial environmental heterogeneity on ant community structure in temperate seminatural upland grasslands of Central ...

Extending Seqenv: a taxa-centric approach to environmental annotations of 16S rDNA sequences [PDF]

open access: yes, 2017
Understanding how the environment selects a given taxon and the diversity patterns that emerge as a result of environmental filtering can dramatically improve our ability to analyse any environment in depth as well as advancing our knowledge on how the ...

Assembly processes of gastropod community change with horizontal and vertical zonation in ancient Lake Ohrid: a metacommunity speciation perspective [PDF]

open access: yes, 2016
The Balkan Lake Ohrid is the oldest and most diverse freshwater lacustrine system in Europe. However, it remains unclear whether species community composition, as well as the diversification of its endemic taxa, is mainly driven by dispersal limitation ...

Habitat filtering determines spatial variation of macroinvertebrate community traits in northern headwater streams [PDF]

open access: yes, 2013
Although our knowledge of the spatial distribution of stream organisms has been increasing rapidly in the last decades, there is still little consensus about trait-based variability of macroinvertebrate communities within and between catchments in near ...

Environmental Impact of UV Filters.

open access: yesActas dermo-sifiliograficas, 2022
UV filters are used daily by millions of people. Not all of these filters, however, are 100% biodegradable, and many wastewater treatments plants are ill-equipped to filter them properly. As a result, UV filters are increasingly reaching the environment.

Theoretical consequences of trait-based environmental filtering for the breadth and shape of the niche: New testable hypotheses generated by the Traitspace model [PDF]

open access: yes, 2015
Every species on Earth fills a unique environmental niche that is driven, in part, by the process of environmental filtering, where the adaptive value of the functional traits of individuals determine their fitness within the given environmental ...

Applying trait-based models to achieve functional targets for theory-driven ecological restoration [PDF]

open access: yes, 2014
Manipulating community assemblages to achieve functional targets is a key component of restoring degraded ecosystems. The response-and-effect trait framework provides a conceptual foundation for translating restoration goals into functional trait targets,
