Timing as a sexually selected trait: the right mate at the right moment [PDF]
, 2017 Sexual selection favours the expression of traits in one sex that attract members of the opposite sex for mating. The nature of sexually selected traits such as vocalization, colour and ornamentation, their fitness benefits as well as their costs have ...

Nordic Journal of Botany, Volume 2025, Issue 12, December 2025.Campanula teucrioides Boiss. is a critically endangered species found in a single locality in western Turkey. Determining the population size of C. teucrioides and conducting reproductive biology studies are of great importance in determining the necessary strategy for the conservation of the species. The area where the plant distributed was determined

Mixed effects of urbanization on pollination services among four native plant species
Ecological Entomology, Volume 50, Issue 6, Page 1184-1195, December 2025.We tested urbanization and fragmentation effects on pollination services using four native phytometer species that were deployed across 10 community gardens located in suburban and densely urbanized areas Landscape context generally did not influence pollination; however, for one of four phytometers (Lobelia siphilitica, pictured above) urban cover ...

Molecular Ecology, Volume 34, Issue 24, December 2025.ABSTRACT Seed production on native seed farms has increased to meet the rising demand for plant material for restoration. Although these propagation efforts are necessary for restoration, cultivating wild populations may also result in unintentional selection and elicit evolutionary changes that mimic crop domestication, essentially turning these ...

Local climate determines intra- and interspecific variation in sexual size dimorphism in mountain grasshopper communities [PDF]
, 2013 The climate is often evoked to explain broad-scale clines of body size, yet its involvement in the processes that generate size inequality in the two sexes (sexual size dimorphism) remains elusive.

Evidence of sequential hermaphroditism in alfonsinos (Beryx spp.) from the deep northeast Atlantic
Journal of Fish Biology, Volume 107, Issue 5, Page 1833-1838, November 2025.Abstract Among 572 specimens of Beryx splendens and B. decadactylus collected in the Azores (northeast Atlantic), we identified 66 hermaphroditic females, primarily of medium size and at early stages of gonadal development. Hermaphroditism was observed more frequently in winter for B. splendens and in spring–summer for B. decadactylus.

Geographic, genetic and life-history variability in a sex-changing fish
Frontiers in Marine Science, 2015 Sequential hermaphroditism, commonly referred to as sex change or sex reversal, is a striking phenomenon in mating-system evolution and the most remarkable example of sexual plasticity. Among vertebrates, it is specific to teleosts.
