Meyna grisea (King & Gamble) Robyns and Meyna peltata Robyns (Rubiaceae: Vanguerieae) – a new record of two ethnobotanically significant fruit trees from Manipur, India

open access: yesNordic Journal of Botany, EarlyView.
Meyna grisea and M. peltata, two new records from Imphal Valley, Manipur, India, characterised by a capitate stigma with 4–5 divergent, spreading lobes on a globose base, and a prominent peltate stigma, respectively, are described and illustrated here. Photographs, key to the species, along with their coordinates and diagnostic characters in comparison

Defense heterosis as a novel plant protection strategy: From theory to breeding practice

open access: yesNew Plant Protection, EarlyView.
Defense heterosis, the enhanced disease resistance of hybrids compared to their parents, has evolved from early observations of hybrid vigor to a novel research concept. Advances are now clarifying its diverse genetic and molecular mechanisms across various plant–pathogen interactions.

Multiple scales of fear: foraging behaviour of white‐naped jays in semiarid landscapes

open access: yesOikos, EarlyView.
Animals must constantly balance the need to find resources with the risk of predation. Not only avoiding direct encounters with predators but also assessing the overall risk of their environment using cues, social information or habitat traits at multiple spatial and temporal scales.

Butterfly and moth habitat specialisation changes along an elevational gradient of tropical forests on Mount Cameroon

open access: yesOikos, EarlyView.
Niche breadth, reflecting the range of environmental conditions or resources a species can exploit, influences its distribution, persistence, vulnerability to environmental change, and interspecific interactions. The elevational niche‐breadth hypothesis predicts broader ecological niches at higher elevations due to increased environmental stress and ...

Greater future range expansions in alien than native ant species

open access: yesOikos, EarlyView.
There is growing concern that many species may not be able to track suitable conditions under climate change and suffer range contractions as a result. At the same time, alien species introduced to novel geographic ranges are often assumed to benefit from climate change.
