Standardized nuclear markers improve and homogenize species delimitation in Metazoa

open access: yesMethods in Ecology and Evolution, 2023
Species are the fundamental units of life and evolution. Their recognition is essential for science and society. Molecular methods have been increasingly used for the identification of animal species, despite several challenges.

Transcriptomics provides a robust framework for the relationships of the major clades of cladobranch sea slugs (Mollusca, Gastropoda, Heterobranchia), but fails to resolve the position of the enigmatic genus Embletonia

open access: yesBMC Ecology and Evolution, 2021
Background The soft-bodied cladobranch sea slugs represent roughly half of the biodiversity of marine nudibranch molluscs on the planet. Despite their global distribution from shallow waters to the deep sea, from tropical into polar seas, and their ...

New evidence on the identity of the European Helorus species (Hymenoptera, Proctotrupoidea, Heloridae) [PDF]

open access: yesBiodiversity Data Journal
Species of Helorus Latreille 1802 are rarely collected endoparasitoids of Chrysopidae larvae (Neuroptera). Previous work on the limits between the European species of this species-poor genus, based on morphology only, has left some uncertainties.

Biodiversity's big wet secret: the global distribution of marine biological records reveals chronic under-exploration of the deep pelagic ocean [PDF]

open access: yes, 2010
Background: Understanding the distribution of marine biodiversity is a crucial first step towards the effective and sustainable management of marine ecosystems. Recent efforts to collate location records from marine surveys enable us to assemble a global

Human impacts on the distribution and genetic diversity of Eurasian minnows (Phoxinus: Leuciscidae) in the Rhenish Massif

open access: yesKnowledge and Management of Aquatic Ecosystems
Introductions of non-native species, a key driver of biodiversity loss, may be underestimated due to cryptic species. In the Rhenish Massif (western Germany), anthropogenic introductions of Eurasian minnows (Phoxinus) caused discrepancies in genetic ...

Specialist Birds Replace Generalists in Grassland Remnants as Land Use Change Intensifies

open access: yesFrontiers in Ecology and Evolution, 2021
The ideal free distribution theory predicts that mobile species distribute themselves among habitat patches so as to optimize their fitness. Changes in land use alter the quality of habitat patches and thereby affect the distribution of species ...
