Revista Mexicana de Biodiversidad, 2020 The analysis of the reproductive output variation within a lineage is fundamental to understand life-history evolution. When different reproductive modes occur within the same lineage, the comparison of the reproductive output of each mode becomes ...

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.

Evolution of reproductive modes in sharks and rays
Journal of Evolutionary Biology, 2023 Abstract The ecological and life history drivers of the diversification of reproductive modes in early vertebrates are not fully understood. Sharks, rays and chimaeras (group Chondrichthyes) have an unusually diverse variety of reproductive modes and are thus an ideal group to test the factors driving the evolution of reproductive ...

How does the mode of evolutionary divergence affect reproductive isolation?
Peer Community Journal, 2023 When divergent populations interbreed, the outcome will be affected by the genomic and phenotypic differences that they have accumulated. In this way, the mode of evolutionary divergence between populations may have predictable consequences for the ...

An unusual reproductive mode in Hypsiboas (Anura: Hylidae)
Zoologia (Curitiba), 2011 We report an unusual reproductive behavior of Hypsiboas pardalis (Spix, 1824). Species belonging to this genus usually are known to reproduce in lentic water bodies, with the development of exotrophic tadpoles.

Comparative transcriptional analysis of asexual and sexual morphs reveals possible mechanisms in reproductive polyphenism of the cotton aphid. [PDF]
PLoS ONE, 2014 Aphids, the destructive insect pests in the agriculture, horticulture and forestry, are capable of reproducing asexually and sexually upon environmental change. However, the molecular basis of aphid reproductive mode switch remains an enigma.

Plants, 2021 DNA methylation is an epigenetic mechanism by which a methyl group is added to a cytosine or an adenine. When located in a gene/regulatory sequence it may repress or de-repress genes, depending on the context and species.

Ploidy levels and reproductive behaviour in invasive Hieracium pilosella in Patagonia [PDF]
, 2011 Within a population of invasive Hieracium pilosella in Chilean Patagonia we found two ploidy levels, pentaploid and hexaploid. Each ploidy level was represented by one clone.
