Hunting Guild Mediates the Effects of Fecundity and Mortality on Sexual Size Dimorphism in Spiders
Ecology and Evolution, Volume 16, Issue 7, July 2026.Female red‐legged golden orb‐weaver (Trichonephila inaurata madagascarensis) with a much smaller male visible near the tip of the female abdomen, southwest Madagascar. Orb‐web weavers are characterised by relatively sedentary females occupying aerial orb webs and highly mobile mate‐searching males.

Ecological and evolutionary consequences of alternative sex-change pathways in fish
Scientific Reports, 2017 Sequentially hermaphroditic fish change sex from male to female (protandry) or vice versa (protogyny), increasing their fitness by becoming highly fecund females or large dominant males, respectively.

Sex Ratios Within the Quasi‐Social Parasitoid Genus Sclerodermus
Entomological Research, Volume 56, Issue 7, July 2026.ABSTRACT Sex ratios are an important component of parasitoid wasps' reproductive strategies and seem to be generally well described by evolutionary ecological theory, such as local mate competition (LMC). The sex ratios of several Sclerodermus species do not fit the predictions of standard LMC models, as their sex ratios remain strongly female biased ...

Entomologia Experimentalis et Applicata, Volume 174, Issue 7, Page 736-749, July 2026.We measured the plasticity in sexual bimaturism (SBM; differences between sexes in the timing of sexual maturity) in the black soldier fly (BSF) by exposing larvae to nutrient availability and humidity stress. Our results show that SBM can range between protandry and protogyny depending on the environmental quality. Additionally, we found the degree of

Nordic Journal of Botany, Volume 2026, Issue 6, June 2026.Penstemon digitalis is an early spring‐flowering species of the northwest Missouri prairie community, a period often characterized by low and unpredictable bee visitation. We conducted an experimental field study to evaluate how pollinator‐mediated pollen transfer and floral longevity interact to influence pollen acquisition and seed production.

Frontiers in Zoology, 2019 Background Habitat quality is one main trigger for the persistence of butterflies. The effects of the influencing biotic and abiotic factors may be enhanced by the challenging conditions in high-alpine environments. To better our knowledge in this field,

Is Self‐Pollination Sufficient to Maximise Seed Set and Fruit Quality in Kiwifruit Hermaphrodites?
New Zealand Journal of Crop and Horticultural Science, Volume 54, Issue 2, June 2026.The purpose of this study was to determine whether supplementary pollination of each of two hermaphrodite kiwifruit selections was likely to produce any significant improvement in seed set or fruit quality, compared with self‐pollination alone. Three main pollination treatments were applied to floral shoots: self‐pollination alone and self‐pollination ...

Evidence of protandry in Aa Rchb.f. (Orchidaceae, Cranichideae)
Lankesteriana, 2011 Protandry has been described in orchids since Darwin (1862) as a strategy to promote cross-pollination. Three different forms of protandry have been reported in tribe Cranichideae: downward movement of the labellum in Spiranthes species, upward movement of the column in Sauroglossum elatum Lindl.
