Sparse genetic data limit biodiversity assessments in protected areas globally

open access: yesFrontiers in Ecology and the Environment, Volume 23, Issue 8, October 2025.
Global conservation targets include protecting genetic diversity within species. Yet few studies have assessed whether protected areas (PAs) include genetically diverse populations across species globally. A first step is understanding the availability of population genetic data that could be used in these assessments.

Cortical cytasters: a highly conserved developmental trait of Bilateria with similarities to Ctenophora

open access: yesEvoDevo, 2011
Background Cytasters (cytoplasmic asters) are centriole-based nucleation centers of microtubule polymerization that are observable in large numbers in the cortical cytoplasm of the egg and zygote of bilaterian organisms.

Reply to Halanych et al.: Ctenophore misplacement is corroborated by independent datasets [PDF]

open access: yes, 2016
In their letter, Halanych et al. (1) criticize our recent assertion (2) that the phylogenetic placement of ctenophores as the sister group to all other animals (the Ctenophora-sister hypothesis) in three previous studies (3–5) was an artifact caused by ...

Food availability drives plastic self-repair response in a basal metazoan- case study on the ctenophore Mnemiopsis leidyi A. Agassiz 1865 [PDF]

open access: yes, 2017
Many marine invertebrates including ctenophores are capable of extensive body regeneration when injured. However, as for the invasive ctenophore Mnemiopsis leidyi, there is a constant subportion of individuals not undergoing whole body regeneration but ...

Effect of temperature on clearance rate, daily ration and digestion time of Mnemiopsis leidyi from the southern Caspian Sea [PDF]

open access: yes, 2012
The effect of temperature on the main feeding parameters of Mnemiopsis leidyi from the southern Caspian Sea was studied in 2002. The clearance rates and daily rations were estimated from laboratory experiments in a wide range of temperatures from 12 to ...

The origin of the Hox/ParaHox genes, the Ghost Locus hypothesis and the complexity of the first animal [PDF]

open access: yes, 2015
A key aim in evolutionary biology is to deduce ancestral states in order to better understand the evolutionary origins of clades of interest and the diversification process(es) that have elaborated them.
