Topological Polaritonic Metamaterials Realized in Bulk Transition Metal Dichalcogenide Crystals

Small Structures, EarlyView.
Monolithic all‐van der Waals materials‐based polaritonic topological insulators are introduced and demonstrated that support robust boundary modes for extreme confinement and robust propagation of strongly coupled exciton‐photon hybrid particles, which are readily tunable with temperature. These monolithic polaritonic topological metasurfaces can serve

Ecological function over evolutionary legacy: The limited role of shared evolutionary history in shaping modern frugivory interactions

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Frugivory, encompassing interactions between vertebrates and plants that range from mutualistic to antagonistic, drives seed dispersal and underpins the structure and resilience of tropical ecosystems.

Savanna tree species show contrasting acclimation responses to elevated atmospheric CO2 concentration and drought

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Woody plant expansion into historically grass‐dominated savannas is reshaping ecosystem structure and function, with consequences for biodiversity, nutrient cycling and land use.

Cretaceous lacewing larvae with binocular vision demonstrate the convergent evolution of sophisticated simple eyes

Insect Science, EarlyView.
We report three ca. 100 million‐year‐old lacewing larvae with extraordinarily large stemmata. One of them additionally has a very wide head, which represents a previously unknown morphology. The arrangement of the stemmata indicates stereoscopic vision in these predatory larvae.

Potential Correlation Between Bombus lantschouensis Thoracic Morphology and Flight Behavior

Integrative Zoology, EarlyView.
Potential correlation between Bombus lantschouensis thoracic morphology and flight behavior. ABSTRACT Remarkably little modern work has investigated the thoracic structures of insects and their relationship to flight locomotion. Most studies focus exclusively on either morphology or flight kinematics.

Harvesting benefits: Exploring the effects of second‐best policies on enhancing soil organic carbon stocks in agriculture

American Journal of Agricultural Economics, EarlyView.
Abstract Agricultural subsidies can be an effective policy tool to enhance soil organic carbon sequestration. This paper assesses the effectiveness of a second‐best hypothetical policy which subsidizes additional canola hectares optimally for each soil zone in Saskatchewan in an effort to increase soil organic carbon.

Exploring dietary adaptations in Ursus minimus: a 3D geometric morphometric analysis of the mandible

Boreas, EarlyView.
Using 3D geometric morphometrics, the dietary adaptations of the extinct Auvergne bear (Ursus minimus) are analysed. Its mandibular morphology aligns more closely with omnivorous rather than insectivorous bears, challenging current ideas. The extinct bear Ursus minimus, which lived in Europe during the Pliocene and possibly Early Pleistocene, is ...

Pollination ecology in the tropical Andes: moving towards a cross‐scale approach

Biological Reviews, EarlyView.
ABSTRACT Plant–pollinator interactions structure ecological communities and represent a key component of ecosystem functioning. Pollination networks are expected to be more diverse and specialised in the tropics, but pollination ecology in these regions has been understudied in comparison to other areas.

Offshoring and Labor Market Power: Comparing Belgian and Dutch Firms

Industrial Relations: A Journal of Economy and Society, EarlyView.
ABSTRACT We study the relationship between offshoring and labor market imperfections at the firm level in Belgium and the Netherlands. In both countries, wage‐markup pricing stemming from workers' monopoly power is more prevalent than wage‐markdown pricing originating from firms' monopsony power.

Associations between fishes (Actinopterygii: Teleostei) and anthozoans (Anthozoa: Hexacorallia) in epipelagic waters based on in situ records

Journal of Fish Biology, EarlyView.
Abstract We formally describe the association of fishes and anthozoans in epipelagic waters, extending this relationship to beyond the benthos. In situ observations and photographs of Aluterus schoepfii, Ariomma regulus, Caranx cf. latus and Brama spp.
