Sociobiology, 2013 Reproductive systems of termite colonies may involve the number of individuals in the reproductive caste and the copulatory selectivity of reproductive individuals (i.e., polyandry or polygamy), both of which directly impact the fertility and genetic ...

Journal of Biogeography, Volume 52, Issue 11, November 2025.ABSTRACT Aim The evolution of adaptive innovations carries strong eco‐evolutionary implications, allowing organisms to explore novel ecological opportunities, which facilitates lineage diversification. The remarkable diversity of reproductive strategies in amphibians provides a natural laboratory for identifying ecological mechanisms driving ...

TAXON, Volume 74, Issue 5, Page 1035-1053, October 2025.Abstract Allium oreophilum, hitherto the representative of the monotypic A. subg. Porphyroprason from the second evolutionary lineage of Allium, is studied in detail. Over about 150 years, A. oreophilum was regarded as a somewhat polymorphous species with two synonyms, all described in the 19th century.

Molecular Ecology, Volume 34, Issue 19, October 2025.ABSTRACT Salmonids have a remarkable ability to form sympatric morphs after postglacial colonisation of freshwater lakes. These morphs often differ in morphology, feeding and spawning behaviour. Here, we explored the genetic basis of morph differentiation in Arctic charr (n = 283) by first establishing a high‐quality reference genome and then using ...

Reduced Adult Neurogenesis in Humans Results From a Tradeoff Rather Than Direct Negative Selection
BioEssays, Volume 47, Issue 9, September 2025.Embryonic radial glia (RG) generate neurons, glial cells, and later adult neural stem cells, which sustain adult neurogenesis (top, left to right). Human‐specific genetic modifications (blue arrow), selected to boost early RG neurogenic activity, may lead to premature RG exhaustion and reduced adult neurogenesis in the human brain (bottom).

Journal of Anatomy, Volume 247, Issue 3-4, Page 643-664, September/October 2025.Abstract Ornithopods are an extinct group of dinosaurs that were particularly abundant and diverse in the Cretaceous of the Iberian Peninsula, and whose abundance in the Maestrazgo Basin has allowed numerous taxa to be identified over the last decade. Many of these fossil remains are still taxonomically indeterminate and require a more detailed study ...

Size and heterozygosity influence partner selection in the Formosan subterranean termite [PDF]
, 2008 In monogamous species that exhibit extensive biparental investment, such as termites, both sexes are predicted to be selective when choosing a mate. Size-related traits are expected to be important in partner selection because the fat reserves of the ...

The Role of Play in Language Structure, Acquisition and Evolution
Language and Linguistics Compass, Volume 19, Issue 5, September/October 2025.ABSTRACT Similarly to language, play is an essential component of human behaviour and culture. However, the links between play and language have been underexamined and often neglected beyond the aesthetic uses of language as found in literature. But playing pervades language.

Unusual Sperm Morphology in Two Sedentary Songbird Species
Ecology and Evolution, Volume 15, Issue 8, August 2025.We describe two dramatic evolutionary shifts in sperm morphology in songbirds, which are independent of but similar to two previously known shifts. Species with this atypical, “tadpole‐like” sperm morphology appear to share sedentary life histories with long‐term pair bonds, high paternal investment, and likely low post‐copulatory sexual selection ...

Discovery of Two Aleocharine Staphylinid Species (Coleoptera) Associated with Coptotermes formosanus (Isoptera: Rhinotermitidae) from Central Japan, with a Review of the Possible Natural Distribution of C. formosanus in Japan and Surrounding Countries [PDF]
, 2014 Two termitophilous staphylinid beetles, Japanophilus hojoi Maruyama & Iwata and Sinophilus yukoae Maruyama & Iwata (Staphylinidae: Aleocharinae) are known to inhabit nests of a termite species, Coptotermes formosanus Shiraki (Rhinotermitidae ...
