1859. On the origin of species by means of natural selection, or the preservation of the favoured races in the struggle for life. London: John Murray. Darwin emphasized the importance of divergent selection for adaptation to different habitats in the origin of species. His concept of species ...
We defined as specialists those archaeal lineages that were more frequently represented in most of the sites within a specific habitat, a definition closely related to the concept of indicator species used in ecology (Dufrene and Legendre, 1997). We applied this concept to the whole set of arch...
In subject area: Biochemistry, Genetics and Molecular Biology Ecological specialization of a pollination system is the number of species that an organism interacts with (or primarily with). From: Trends in Plant Science, 2020 About this pageAdd to MendeleySet alert ...
remains largely absent from global conversations. This oversight is due in part to the lack of a clear definition of prevention and lack of guidance on how to achieve it. To address this gap, we elucidate the mechanisms linking environmental change and zoonotic spillover using spillover of virus...

The ‘classical’ concept of species diversity was extended in the last decades into other dimensions focusing on the functional and phylogenetic diversity of communities. These measures are often argued to allow a deeper understanding of the mechanisms shaping community assembly along environmental gradien...
Forest ecosystems undergo significant transformations due to harvesting and climate fluctuations, emphasizing the critical role of seeding in natural regeneration and long-term structural preservation. Climate change further amplifies these dynamics, aff
Microbial communities often perform important functions that depend on inter-species interactions. To improve community function via artificial selection, one can repeatedly grow many communities to allow mutations to arise, and “reproduce” the highest-functioning communities by partitioning each into multi...
The pattern of species abundance, represented by the number of individuals per species within an ecological community, is one of the fundamental characteristics of biodiversity. However, despite their obvious significance in ecology and biogeography, the
