Fatal attraction: rare species in the spotlight [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2009
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 species perform worse than common species under changed climate [PDF]

, 2019
Predicting how species, particularly rare and endangered ones, will react to climate change is a major current challenge in ecology. Rare species are expected to have a narrower niche width than common species.

Rare species perform worse than widespread species under changed climate

, 2020
Predicting how species, particularly rare and endangered ones, will react to climate change is a major current challenge in ecology. Rare species are expected to have a narrower niche width than more widespread species.

Relative contribution of abundant and rare species to species–energy relationships [PDF]

Biology Letters, 2005
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.

Why Some Plant Species Are Rare

PLoS ONE, 2014
Biodiversity, including plant species diversity, is threatened worldwide as a result of anthropogenic pressures such as an increase of pollutants and climate change. Rare species in particular are on the verge of becoming extinct. It is still unclear as to why some plant species are rare and others are not.

The physician-scientists: rare species in Africa

Pan African Medical Journal, 2018
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.

Locally rare species influence grassland ecosystem multifunctionality [PDF]

, 2016
Species diversity promotes the delivery of multiple ecosystem functions (multifunctionality). However, the relative functional importance of rare and common species in driving the biodiversity–multifunctionality relationship remains unknown.

Estimating sample representativeness in a survey of stream caddisfly fauna

, 2006
Obtaining an adequate and representative sample is a continuing challenge of community ecology. The present study focuses on what sample area represents adequately the structural composition of the caddisfly fauna of a riffle, at a given sampling ...

Measuring the conservation value of tropical primary forests : the effect of occasional species on estimates of biodiversity uniqueness [PDF]

, 2010
Background Developing effective conservation plans for multi-functional landscapes requires an accurate knowledge of the relative conservation value of different land-uses.

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

FEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...
