Superclone Expansion, Long-Distance Clonal Dispersal and Local Genetic Structuring in the Coral Pocillopora damicornis Type β in Reunion Island, South Western Indian Ocean.

PLoS ONE, 2017
The scleractinian coral Pocillopora damicornis type β is known to present a mixed reproduction mode: through sexual reproduction, new genotypes are created, while asexual reproduction insures their propagation.

Evolution of asexual and sexual reproduction in the aspergilli

Studies in Mycology, 2018
Aspergillus nidulans has long-been used as a model organism to gain insights into the genetic basis of asexual and sexual developmental processes both in other members of the genus Aspergillus , and filamentous fungi in general.

Multi‐level nitrogen and phosphorus addition synergistically reduces alpine grassland stability via species compositional changes

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Nutrient addition generally weakens the stabilizing effects of plant diversity on grassland productivity. However, whether this destabilizing effect is associated with species compositional changes and varies with nutrient input levels remains unclear.

Effective purifying selection in ancient asexual oribatid mites

Nature Communications, 2017
Asexual reproduction is thought to be an evolutionary dead end in eukaryotes because deleterious mutations will not be purged effectively. Here, Brandt and colleagues show that anciently asexual oribatid mites in fact have reduced accumulation of ...

Plant Growth-Promoting Rhizobacteria Stimulate Vegetative Growth and Asexual Reproduction of Kalanchoe daigremontiana

The Plant Pathology Journal, 2015
Certain bacterial species associate with plant roots in soil. The plant growth-promoting rhizobacteria (PGPR) stimulate plant growth and yield in greenhouse and field.

Mechanisms of asexual reproduction in reptiles [PDF]

, 2015
In the case of reptiles, there has been described an occurrence of an asexual reproduction, especially in the case of a group Squamata; the asexual reproduction of birds (Aves) has been observed, too.

‘More Beastliness Than Beauty’: Gendering Pica in Seventeenth‐Century English Medicine and Culture

Gender &History, EarlyView.
ABSTRACT Today, defined as the ‘persistent eating of non‐nutritive substances’, pica is a lesser‐known eating disorder with a long history. Defined in early modern England as the ‘desire to eat absurd things’, pica was explicitly gendered, associated with pregnant women and pubescent girls.

Epigenomic and transcriptomic persistence of heat stress memory in strawberry (Fragaria vesca)

BMC Plant Biology
Background In plants, epigenetic stress memory has so far been found to be largely transient. Here, we wanted to assess the heritability of heat stress-induced epigenetic and transcriptomic changes following woodland strawberry (Fragaria vesca ...

Data from: Is asexual reproduction an evolutionary dead-end in lichens?

, 2016
Classical hypotheses in lichenology predict pairs of species in which sexual lineages are ancestral and long-lived evolutionarily and that these give rise to derived, evolutionarily transient asexual lineages. Extensive phylogenetic information generated
