N is the total number of reaches; we multiply by (N−Pj) because sites must be unoccupied to be colonized. Finally, c is the colonization rate, which is a function of the DOM concentration, thereby linking it to the physical equation. The second term describes extinctions and follows ...
2b), suggesting that the temporal behaviours in the systems cannot always be explained by long-term seasonal and environmental factors, but probably by the ecological interactions of the microbes involved. More specifically, S17 sees the rise in abundance or gene expression of three bacterial ...
Despite the global efforts of hundreds of forest scientists over the past 3 decades, forests are degrading at an accelerated rate and biodiversity is increasingly threatened by human activities. Given these trends - despite the very best efforts of the world’s best scientists - other approaches ...
The term “soil quality” was coined in this context, but more recently the term “soil health” has become common (Chapters 14 and 251425). Soil quality is the ability of a soil to function within its surroundings, support plant and animal productivity, and maintain or enhance water and ...

We then presented six common definitions of the term “ecosystem” and asked participants to rank their most and least favorite of these definitions (Box 2). Survey participants were also given an opportunity to propose their own definition. The first part of the survey then ended with the ...
PARIS, June 12 (Xinhua) -- As French President Emmanuel Macron began the third year of his five-year term amid social malaise, he has put the environment and social justice "at the heart" of his policymaking, seeking ways to accelerate the energy transition, guaranteeing that "work pays",...
from ephemeral changes in physical energy and sediment suspension in a breaking wave, to annual cycles of biological activity and soil biogeochemistry associated with flooding, to long-term evolution of shore zone geomorphology following changes in climate or land use in the watershed. All of these ...
In general, long-term isolation can only be confidently assumed when spatially concordant patterns across multiple unlinked loci are found [29, 32]. Disentangling historical from ongoing constraints to dispersal may also be problematic. Phylogeographical breaks and contemporary oceanographic barriers (or ...
and can inform future management decisions. Observations made at the site may indicate that further action, such as periodic weed removal, is necessary in ensuring the long-term success of the project. Ideally restoration projects would eventually achieve a self-sustaining ecosystem without the need ...
