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
Comparative anatomy of the larvae of argid sawflies (Hymenoptera: Argidae): a phylogenetic approachOrganisms Diversity and Evolution - Tập 21 - Trang 361-392 - 2021
Leonardo A. Malagon-Aldana, Akihiko Shinohara, David R. Smith, Lars Vilhelmsen
The larval stage remains unknown for many sawflies, making it difficult to
explore the phylogenetic significance of larval morphology. Here, we assemble a
data set from the larval anatomy of 22 genera of Argidae and Zenargidae. We
scored 85 characters for 48 terminal taxa and use a maximum parsimony approach
applying equal (EW) and implied weights (IW) for phylogenetic reconstruction. We
describe ... 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
