Echoes of Evolution in Holocentridae: Harmony Between Phylogeny, Morphology and Acoustics
Ecology and Evolution, Volume 16, Issue 8, August 2026.Using phylogenetic, morphological, and acoustic data from 53 species, we reconstructed the evolution of acoustic communication in nocturnal reef fishes of the family Holocentridae. Our results reveal two major clades with distinct sound‐producing morphologies and acoustic features, and suggest a three‐step diversification process involving the ...

Ecology and Evolution, Volume 16, Issue 8, August 2026.Phylogeographic pseudo‐concordance among species—coincident spatial structuring coupled with differing levels of intraspecific differentiation—has rarely been documented in heterogeneous regions. We report a clear case in two mountain butterfly species and show how the high density of spatial sampling and the integration of phenotypic and genomic ...

An Elementary Microscopic Model of Sympatric Speciation
Using as a narrative theme the example of Darwin’s finches, a microscopic agent-based model is introduced to study sympatric speciation as a result of competition for resources in the same ecological niche. Varying competition among individuals and resource distribution, the model exhibits some of the main features of evolutionary branching processes ...

Austral Entomology, Volume 65, Issue 3, August 2026.ABSTRACT A new species of jewel beetle, Temognatha sundholmi Lang, sp. nov., is described from the Great Victoria Desert in South Australia. A broader investigation, using mtDNA COI ‘barcode’ sequences from 178 specimens representing 54 buprestid species, places the new species with Temognatha flavocincta (Gory & Laporte, 1838) in the informal ...

Austral Entomology, Volume 65, Issue 3, August 2026.ABSTRACT The Oiketicinae genus Hyalinaria Bethune‐Baker, 1910, is revised. The use of both morphological information and genetic sequence data indicates that Hyalinaria and Pseudoclania Bethune‐Baker, 1915 sp. nov., are synonymous, with the latter genus here treated as a junior subjective synonym of the former.

Insects, 2019 Ascertaining the causes of adaptive radiation is central to understanding how new species arise and come to vary with their resources. The ecological theory posits adaptive radiation via divergent natural selection associated with novel resource use; an ...

Austral Entomology, Volume 65, Issue 3, August 2026.ABSTRACT A maximum parsimony analysis based on morphological characters (23 taxa; 98 characters; 1951 scorings) was conducted to test the monophyly of Discocyrtulus Roewer, 1927, and to assess its phylogenetic relationships within Gonyleptidae. The results recover the species currently assigned to Discocyrtulus as phylogenetically distant from ...
