Pavonia fretensis sp. nov. (Malvaceae) from the Horn of Africa hotspot

open access: yesNordic Journal of Botany, EarlyView.
The new species Pavonia fretensis is described, illustrated by photographs and mapped. It occurs in coastal localities on both sides of the Bab al Mandab Strait and is known from southern Yemen, Eritrea and northwestern Somalia. The species differs from Pavonia rotundifolia from eastern Ethiopia and northern and central Somalia by having stellate ...

Canscora agni (Gentianaceae), a new species from the fire‐prone Indian savannas

open access: yesNordic Journal of Botany, EarlyView.
We describe Canscora agni from the Indian savannas as a distinct species which differs from its allied species Canscora alata in having fewer and shorter leaves, pedicel‐wings unequal across the length, bracts with glandular hair on the margins, calyx‐wings being four, wider, up to 2.3 mm, with distinct reticulate venation and having ovary length up to

Habitat loss reshuffles ecological and evolutionary interactions in a seed dispersal network

open access: yesOikos, EarlyView.
In tropical forests, habitat loss reshapes species composition, favoring generalists and recently emerged lineages while specialists and older evolutionary lineages are lost. However, how changes in species ecological attributes and evolutionary history affect ecological processes is poorly explored.

Plant and insect functional traits influence herbivore performance under climate change

open access: yesOikos, EarlyView.
Climate change is expected to disrupt many trophic interactions, including those between insect herbivores and their host plants, which could have detrimental effects at the ecosystem level. However, the response of insect herbivory to climate change can vary widely across species, and an understanding of the mechanisms underlying this variation is ...

Population recovery of an endangered macaw enhances long‐distance seed dispersal via stomatochory

open access: yesOikos, EarlyView.
Seed dispersal by large, mobile vertebrates plays a key role in shaping plant spatial dynamics and community structure. However, how variation in animal population size influences the magnitude and spatial scale of seed dispersal remains poorly understood.

Cotton facilitates long‐distance seed dispersal by functioning as nest material for birds

open access: yesOikos, EarlyView.
Cotton (Cossypium) fibres, which grow naturally in bolls around the seeds of cotton plants, have been used for centuries to produce fabric. The presumed natural function of cotton is that these lightweight and fluffy fibres may support wind dispersal of the seeds inside.

The interacting effects of precipitation and microhabitat on non‐native seed predation are contingent on temporal dynamics

open access: yesOikos, EarlyView.
Understanding how different drivers of global change interact to shape ecological processes remains a major challenge in ecology. Climate change is reshuffling the interactions that structure communities, with major implications for biological invasions.

The importance of wild meat and freshwater fish for children's nutritional intake in the Congo Basin

open access: yesPeople and Nature, EarlyView.
Abstract Wild meat and freshwater fish are widely consumed in the Congo Basin, but in some areas, they are at risk of disappearing due to unsustainable hunting and fishing and changes in their habitat. Wild meat is also at risk of being eliminated from local diets due to potential policy changes such as wild meat bans.
