The relative roles of in situ diversification and lineage dispersal underlying diversity patterns at the assemblage level

open access: yesOikos, EarlyView.
Speciation, extinction, and dispersal are the historical processes influencing the spatial distribution of lineages and strongly influence diversity patterns. Here, we apply a recently developed methodological approach to quantify the relative legacies in situ diversification history (i.e.

Structural stability of plant–pollinator interactions despite seasonal abundance of long‐tongued hawkmoths

open access: yesOikos, EarlyView.
Seasonal environmental cycles affect plant–pollinator interactions by altering plant phenology. Periods of low resource availability can filter pollinators and reduce the complexity of interaction networks, but the extent to which the functional morphology of pollinators influences such filtering remains unclear.

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

open access: yesOikos, 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.

The interplay between landscape change and plasticity in habitat selection determines dispersal movements and settlement in small non‐flying vertebrates

open access: yesOikos, EarlyView.
The response of dispersers to landscape changes depends on both external environmental conditions and individual internal conditions, as well as movement and orientation abilities. Plasticity in habitat selection may also affect how individuals respond to landscape changes.

Electrified rhythms: How hydropower infrastructure transforms hydrosocial relations of riverine communities in the Lower Sogamoso River, Colombia

open access: yesPeople and Nature, EarlyView.
Abstract Hydropower dams regulate water flows for millions of downstream inhabitants worldwide, altering water availability. Under a changing climate, flow control is often framed technically and politically as being essential for reducing drought and flood risks. However, it can also disrupt ecological flows, impact livelihoods and erode environmental

Eco‐Friendly Bioplastic Film Produced With Green Plantain Starch (Musa paradisiaca L.): Effect of Activated Carbon Addition and Hydrothermal Modification

open access: yesPolymer Composites, EarlyView.
Activated Carbon as a Reinforcing Material for Starch Bioplastics. ABSTRACT Eco‐friendly starch‐based bioplastic films reinforced with activated carbon (AC) were produced using green plantain starch in its native and heat‐moisture treatment (HMT) forms to overcome typical limitations of starch materials, such as low mechanical strength and poor water ...
