Evolution of reproductive strategies in libellulid dragonflies (Odonata: Anisoptera)Organisms Diversity and Evolution - Tập 12 - Trang 313-323 - 2012
Jessica Ware, Maria Karlsson, Göran Sahlén, Kamilla Koch
In Libellulidae, oocyte production has been assumed to be continuous, with periods of egg-laying interspersed with periods of resting/eating; however, recent work suggests that two types of oocyte production are common: either (a) continuous or (b) step-wise. These are mirrored in the arrangement of the ovarioles in the ovaries. Likewise, two types of mate-guarding behavior have been observed in L...... hiện toàn bộ
Exploring the evolution and terrestrialization of scorpions (Arachnida: Scorpiones) with rocks and clocksOrganisms Diversity and Evolution - Tập 19 - Trang 71-86 - 2019

Scorpions (Arachnida: Scorpiones Koch, 1837) are an ancient chelicerate arthropod lineage characterised by distinctive subdivision of the opisthosoma and venomous toxicity. The crown group is represented by over 2400 extant species, and unambiguous fossil representatives are known at least from the Cretaceous Period. However, a number of extinct scorpion lineages existed in the Palaeozoic Era, man...... hiện toàn bộ
Exploring the diversity of the Malagasy Ponera (Hymenoptera: Formicidae) fauna via integrative taxonomyOrganisms Diversity and Evolution - - Trang 1-11 - 2023
Sándor Csősz, Ana C. Loss, Brian L. Fisher
The genus Ponera includes over 60 extant species worldwide. These tiny, endogeic predator ants are predominantly distributed in the Indomalaya and Australasia regions, with a few additional Holarctic species. Herein, we explore and describe the diversity of the Malagasy Ponera fauna through an integrative taxonomic approach. We obtained our morphological species hypotheses from multivariate analys...... hiện toàn bộ
Two tribes hidden in one genus: the case of Agaedioxenis Villeneuve (Diptera: Tachinidae: Exoristinae)Organisms Diversity and Evolution - Tập 15 - Trang 489-512 - 2015

The Afrotropical tachinid “genus” Agaedioxenis Villeneuve is taken here as an example of the challenges faced by dipterists in classifying one of the most diverse and species rich families of organisms on Earth. Our study has revealed “two tribes hidden in one genus”, with one lineage representing a genus belonging to the tribe Goniini (Agaedioxenis) and the other representing a genus belonging to...... hiện toàn bộ
