Asexual Reproduction in Infectious Diseases

, 2009
Parasitic organisms in the strict sense (eukaryotes) represent a significant part of the general biodiversity which has been described and, with 179 species affecting people worldwide, are of relevance for mankind in particular. Contrary to the classical view, many of these species are clonal.

Mate limitation, recurrent epidemic outbreaks, and the coexistence of sexual and asexual plant parasites [PDF]

, 2014
To date, relatively few studies have focused on the effects of sex on population dynamics. Previous models found that sexual reproduction may either dampen population fluctuations or accentuate population fluctuations, depending on mating system notably.

Bioenergy Cropping Reduces the Spatiotemporal Scaling of Soil Bacterial Biodiversity

Advanced Science, EarlyView.
Consistent with patterns observed in plant and animal communities, soil bacterial communities exhibit significant species–time–area and phylogenetic–time–area relationships independent of nested structure. Bioenergy cropping significantly reduces the spatiotemporal scaling rates, particularly in sandy loam soils.

Detecting cryptic ghost lineage introgression in four‐taxon genomic datasets

Applications in Plant Sciences, EarlyView.
Abstract Premise Hybridization and introgression are pervasive evolutionary forces that have played fundamental roles in shaping the diversity of wild and domesticated plants. Four‐taxon tests for introgression provide a reliable framework for detecting signatures of ancient introgression from genomic data, which have played an important role in ...

Asexual reproduction strategies in the moon jellyfish Aurelia (Cnidaria: Scyphozoa)

Frontiers in Ecology and Evolution, 2023
The genus Aurelia is one of the major contributors to jellyfish blooms in coastal waters, possibly due to its adaptive reproduction strategies. Different Aurelia lineages have adapted their reproduction modes to varying environmental conditions in their ...

Low clonal propagation in Atlantic and Mediterranean populations of the red gorgonian Paramuricea clavata (Octocorallia) [PDF]

, 2017
Clonal propagation is a common feature of benthic marine organisms. In the present study, we investigated the contribution of clonal reproduction in the red gorgonian Paramuricea clavata. Mediterranean populations of P.

The spread of non‐native species

Biological Reviews, EarlyView.
ABSTRACT The global redistribution of species through human agency is one of the defining ecological signatures of the Anthropocene, with biological invasions reshaping biodiversity patterns, ecosystem processes and services, and species interactions globally.

Invasion Fosters Change: Independent Evolutionary Shifts in Reproductive Traits after Oxalis pes-caprae L. Introduction [PDF]

, 2016
Biological invasions offer optimal scenarios to study evolutionary changes under contemporary timescales. After long-distance dispersal, exotic species have to cope with strong mate limitation, and shifts toward uniparental reproduction have been ...

Asynchronous LGBTQ+ Affirming Counseling Training With Early Career Counselors: A Mixed Methods Program Evaluation

Counselor Education and Supervision, EarlyView.
ABSTRACT A growing body of research shows that training in LGBTQ+ affirming counseling (LGBTQ+ AC) positively impacts counselors’ perceived knowledge and skills in providing mental health services to LGBTQ+ communities. Existing program evaluations of LGBTQ+ AC, however, have primarily used synchronous delivery formats and cultural competency models ...

Intensity and mode of Lindera melissifolia reproduction are affected by flooding and light availability

Ecology and Evolution, 2021
We studied the impact of flooding and light availability gradients on sexual and asexual reproduction in Lindera melissifolia (Walt.) Blume, an endangered shrub found in floodplain forests of the Mississippi Alluvial Valley (MAV), USA.
