Fatal attraction: rare species in the spotlight [PDF]
The exploitation of rare and endangered species can end in the species's extinction because the increased value people associate with rarity increases the economic incentive to exploit the last individuals, creating a positive feedback loop. This recently proposed concept, called the anthropogenic Allee effect (AAE), relies on the assumption that ...

Rare Earth Elements in Agriculture with Emphasis on Animal Husbandry [PDF]
Calculations performed in consideration of a continuously increasing world population have revealed that animal production needs to be enhanced worldwide by at least 2 % each year so as to provide sufficient feed.

Relative contribution of abundant and rare species to species–energy relationships [PDF]
Abstract A major goal of ecology is to understand spatial variation in species richness. The latter is markedly influenced by energy availability and appears to be influenced more by common species than rare ones; species–energy relationships should thus be stronger for common species.

Contribution of rare and common species to subterranean species richness patterns [PDF]
AbstractAimCommon species contribute more to species richness patterns (SRPs) than rare species in most studies. Our aim was to test this hypothesis using a novel model system, species living exclusively in subterranean habitats. They consist of mainly rare species (small ranges), only a few of them being common (large ranges), and challenge whether ...

The as-prepared co-doped N/Ag carbon dot (CDNAg) has strong catalysis of H2O2 oxidation of 3,3′-dimethylbiphenyl-4,4′-diamine (DBD). It forms an oxidation product (DBDox) with surface-enhanced Raman scattering (SERS) activity at 1605 cm−

The physician-scientists: rare species in Africa
There is paucity of physician-scientists in Africa, resulting in overt dependence of clinical practice on research findings from advanced "first world" countries. Physician-scientists include individuals with a medical degree alone or combined with other advanced degrees (e.g.

Niche differentiation has been proposed as an explanation for rarity in species assemblages. To test this hypothesis requires quantifying the ecological similarity of species. This similarity can potentially be estimated by using phylogenetic relatedness.
