Taxonomy and diversity of Marcgraviaceae, north of the São Francisco river, northeast Brazil

Nordic Journal of Botany, EarlyView.
This study provides a comprehensive assessment of Marcgraviaceae species diversity north of the São Francisco river in northeastern Brazil, analyzing species richness and distribution patterns across 384 000 km² of phytogeographic domains. Through field collections, herbarium studies (both physical and digital), and detailed morphological analyses, we ...

Forbs in Viking lands: the effect of disturbing dominant graminoids on recruitment in tundra grasslands

Oikos, EarlyView.
Grasslands, by definition, are dominated by graminoids. Nevertheless, forbs also make up a substantial part of vascular plant diversity in grasslands and are important resources of mammalian herbivores. However, forb recruitment is constrained by successful dominant graminoids, limiting access to safe sites for germination.

Aromatic plants, nest bacterial diversity, and nestling condition in Corsican blue tits

Oikos, EarlyView.
According to the ‘nest protection hypothesis', some passerines incorporate fresh aromatic plants into their nests which reduce pathogens that can negatively affect nestlings. We experimentally evaluated the effect of five aromatic plant species on the nest bacterial microbiota of Corsican blue tits Cyanistes caeruleus.

Time tells: plasticity and developmental asynchrony underlie trait variation in a dune‐building grass

Oikos, EarlyView.
Habitat‐modifying plants engineer landscapes through plant‐environment feedbacks. The strength of these feedbacks is determined by above‐ and below‐ground traits shaping landscape morphology. Besides interspecific differences, recent findings highlight that intraspecific trait variation, such as shoot density, can also influence landscape morphology ...

Floral resource diversity drives spatiotemporal variation in plant–pollinator network structure

Oikos, EarlyView.
Mechanisms underlying community assembly, including those related to species interactions, vary across space and time. Plant–pollinator networks exemplify these dynamics, where link rewiring and turnover mediate adaptations to environmental changes. Bees rely on diverse floral resources (e.g.

Response of specific leaf area to light: comparative study of a large species set

Oikos, EarlyView.
Specific leaf area (SLA) is a commonly used proxy for the leaf economy spectrum in plants, separating species with low‐cost leaves (in terms of carbon) with short lifespan and hence fast turnover from species with high‐cost and long‐lived leaves. While SLA is used mainly for interspecific comparisons, it also varies within species both ontogenetically ...

Contrasting effects of temperature across trophic levels in geothermally warmed soil food webs

Oikos, EarlyView.
Global warming is altering the structure and dynamics of ecological communities, with significant consequences for soil food webs. Rising temperatures are expected to accelerate metabolic rates in organisms, potentially altering species interactions, and the structure and energetics of food webs.

On the spatial clustering of behavioural phenotypes: matching movement tactics with landscape structure in a large herbivore

Oikos, EarlyView.
In the wild, individuals consistently differ in movement and space use behaviours, depending on their personality. This variation can lead to personality–habitat associations and spatial structuring, potentially generating individual niche segregation.
