Promotion of cooperation by selective group extinction
New Journal of Physics, 2016 Multilevel selection is an important organizing principle that crucially underlies evolutionary processes from the emergence of cells to eusociality and the economics of nations.

Selective extinction against redundant species buffers functional diversity. [PDF]
Proc Biol Sci, 2020 The extinction of species can destabilize ecological processes. A way to assess the ecological consequences of species loss is by examining changes in functional diversity. The preservation of functional diversity depends on the range of ecological roles performed by species, or functional richness, and the number of species per role, or functional ...

Chemogenetic modulation of CRF neurons in the BNST compensates for phenotypic behavioral differences in fear extinction learning of 5-HT2C receptor mutant mice [PDF]
Translational PsychiatryPsychopharmacotherapy is often used to treat anxiety- and stress-associated psychiatric disorders, including post-traumatic stress disorder (PTSD). Adjunctive therapy is most typically used with medications that influence serotonin balance, such as ...

Species diversity within morpho-functional groups drives diversity dependence in reef ecosystems. [PDF]
PLoS ONEChanges in species diversity can alter reef ecosystem composition by impacting the origination and extinction of species within co-existing groups.

Community stability and selective extinction during Earth’s greatest mass extinction [PDF]
Science, 2015 AbstractWe modelled the resilience and transient dynamics of terrestrial paleocommunities from the Karoo Basin, South Africa, around the Permian-Triassic mass extinction. Using recently refined biostratigraphic data that suggest two pulses of extinction leading up to the Permian-Triassic boundary, we show that during times of low extinction ...

Extinction and morphospace occupation: A critical review
Cambridge Prisms: Extinction, 2023 Processes of extinction, especially selectivity, can be studied using the distribution of species in morphospace. Random extinction reduces the number of species but has little effect on the range of morphologies or ecological roles in a fauna or flora ...

Central amygdala micro-circuits mediate fear extinction
Nature Communications, 2021 The central amygdala inhibitory microcircuits mediate fear extinction by reversible, stimulus- and context-specific changes in neuronal responses. These alterations are absent when extinction is deficient and selective silencing of PKCδ neurons impairs ...

Sexual selection protects against extinction [PDF]
Nature, 2015 Reproduction through sex carries substantial costs, mainly because only half of sexual adults produce offspring. It has been theorized that these costs could be countered if sex allows sexual selection to clear the universal fitness constraint of mutation load.

Mathematical and Computer Modelling of Dynamical Systems, 2023 Controlling antibiotic drug resistance requires understanding extinction and emergence mechanisms of emerging bacteria. Selective pressure from prolonged antibiotic misuse may cause high-level antimicrobial resistance.
