Interpopulation Variation in Seed Germination in Three Plantago Species: Effects of Temperature, Osmotic Stress, and Salinity

open access: yesNew Zealand Journal of Botany, Volume 64, Issue 3, September 2026.
Plantago species are widespread in the Mediterranean and have potential applications in restoration of degraded or saline soils. This study examined germination responses of Plantago albicans, P. coronopus, and P. maritima from multiple Iberian populations under different temperature, osmotic stress, and salinity.

Seed co‐occurrence caused by shared frugivores leaves a long‐lasting signal in the spatial co‐occurrence among plants

open access: yesOikos, Volume 2026, Issue 9, September 2026.
Frugivorous animals are intrinsically involved in plant community dynamics, by dispersing seeds of fleshy‐fruited plants and influencing their spatial co‐occurrence. Particularly, generalist avian frugivores forage on them, co‐dispersing and co‐disseminating their seeds.

Ecological significance of fruit displays in Myrtaceae: relationship between fruit colour, maturation stage, attractiveness and seed germination

open access: yesOikos, Volume 2026, Issue 9, September 2026.
Fruit colour has long fascinated scientists and is widely considered an evolutionary adaptation to attract both avian and mammalian frugivores. While fleshy fruits play a key role in plant–animal interactions by promoting seed dispersal, the functional significance of colour variation, particularly multicoloured displays during ripening, remains poorly

Biogeographic Disconnect and Biotic Homogenization in the Heart of the Amazon: Dominance of Exotic Species in Urban Trees

open access: yesBiotropica, Volume 58, Issue 5, September 2026.
Exotic taxa dominate the urban woody flora, with potentially invasive species posing a direct risk to adjacent primary forest remnants. Historical management has favored a simplified, cosmopolitan species pool over regional biodiversity. There is failure to implement local native‐priority mandates, offering concrete ecological targets for urban ...

Methodological Effects on Plant–Hummingbird Networks: A Comparison of Pollen Load and Focal Observation Approaches in Colombian Andean Ecosystems

open access: yesBiotropica, Volume 58, Issue 5, September 2026.
ABSTRACT Ecological interactions, such as plant–pollinator interactions, are fundamental to maintaining biodiversity and sustaining ecosystem functions. In tropical ecosystems, hummingbirds serve as key pollinators due to their specialized morphological traits, which facilitate plant–pollinator interactions.

Structural Colour in Bees (Hymenoptera: Anthophila) Is Linked to Climate and Latitude

open access: yesGlobal Ecology and Biogeography, Volume 35, Issue 9, September 2026.
ABSTRACT Aim Environmental drivers frequently predict global patterns of colour diversity, but whether such patterns depend on the underlying colour mechanisms—pigments or microscopic structures—has scarcely been considered. Structural colour may have different functional properties that result in different associations with environmental variables ...

Fly me to the canopy: Diptera communities in oak forest crowns as bioindicators of stand decline

open access: yesInsect Conservation and Diversity, Volume 19, Issue 5, Page 1099-1113, September 2026.
Diptera diversity: Oak decline increases the overall Diptera diversity, particularly in saproxylic and floricolous guilds, likely due to more open canopies and greater deadwood and floral resource availability. Family responses: Dolichopodidae, Empididae, Hybotidae and Anthomyiidae thrive in declining stands, whereas Mycetophilidae and other fungus ...
