Ancient origin of a Western Mediterranean radiation of subterranean beetles
TLDR
The results suggest that by the Early-Mid Oligocene the main lineages of Western Mediterranean Leptodirini had developed all modifications to the subterranean life and were already present in the main geographical areas in which they are found today.
Early Pliocene range expansion of a clade of subterranean Pyrenean beetles
To investigate the possibility of range expansion and diversification within the subterranean environment in a genus of troglobiont beetles of the family Leiodidae (Troglocharinus), which have a…
The phylogenetic and geographic limits of Leptodirini (Insecta: Coleoptera: Leiodidae: Cholevinae), with a description of Sciaphyes shestakovi sp. n. from the Russian Far East
TLDR
This poster presents a selection of photos from around the world that highlight the importance of knowing the phytochemical properties of fruit flies to the health of humans and animals.
Life-history specialization was not an evolutionary dead-end in Pyrenean cave beetles
TLDR
Using a comprehensive molecular phylogeny, a low number of independent origins of the reduction in the number of instars are found, with a single transition, dated to the Oligocene–Miocene, from 3 to 2 and then 1 instar in the Pyrenees, the best-studied area.
Molecular phylogeny of the Trechus brucki group, with description of two new species from the Pyreneo-Cantabrian area (France, Spain) (Coleoptera, Carabidae, Trechinae)
TLDR
A molecular phylogeny of the species from the Trechus brucki clade based on fragments of four mitochondrial genes and one nuclear gene is given and a unique synapomorphy of the male genitalia, a characteristic secondary sclerotization of the sperm duct, is described and illustrated.
Psychological Wellbeing of Vulnerable Children During the COVID-19 Pandemic.
TLDR
The children and adolescents in this study had worse psychological wellbeing than those in the 2017 Spanish reference, that is, before the COVID-19 outbreak, and quality of life remained the same.
Phylogeny of western Mediterranean Leptodirini, with an emphasis on genital characters (Coleoptera: Leiodidae: Cholevinae)
TLDR
The phylogeny of the western Mediterranean lineages (Iberian Peninsula, Pyrenees and Sardinia) is assessed based on a cladistic analysis of fourteen characters of external morphology and twenty characters of the male and female genitalia, as well as that of some ‘phyletic series’, suggesting the respective monophyletic origin of the Leptodirini from the Pyrenee and Mediterranean coast plus Sardinia were not monophylets.
A new species of blind Trechinae from the Pyrenees of Huesca, and its position within Aphaenops (sensu stricto) (Coleoptera: Carabidae: Trechini)
A new trechine species Aphaenops parvulus sp. n. (Carabidae, Trechini) is described from Esjamundo cave in the Pyrenees of Huesca, Spain. The new species belongs to the subgenus Aphaenops (sensu…
Allopatric speciation illustrated: The hypogean genus Geotrechus Jeannel, 1919 (Coleoptera: Carabidae: Trechini), with description of four new species from the Eastern Pyrenees (Spain)
The specimen of Geotrechus seijasi used for the molecular part of the work (MZB 2014-2433) was collected during a campaign of the project “Actuacions de seguiment de les poblacions d’invertebrats…
Discovery of a new blind ground beetle in western French Pyrenees, and its relevance to the phylogeny of Pyrenean hypogean Trechini.
TLDR
Molecular data suggests unambiguously strong affinities between the new species and the clade Aphaenops vasconicus Jeannel, 1913-A.
