The dual crisis: Climate change simultaneously drives pollinator decline and pest outbreaks

Agricultural and Forest Entomology, EarlyView.
Climate change acts as an asymmetric ecological filter, favouring r‐selected pest traits (rapid reproduction, generalism) while disadvantaging K‐selected pollinators. For every 1°C of warming, bee species richness declines ~25% since the 1990s, while pest‐induced crop losses increase by 10%–25%. A network‐centric approach integrating climate‐responsive

A theory of political divergence and gradual institutional change

American Journal of Political Science, EarlyView.
Abstract Why do some societies succeed in breaking away from historical traditions while others remain trapped? This paper proposes a formal theory to investigate the interaction between short‐run and long‐run political dynamics, highlighting a co‐evolution of political institutions and social structures.

Geospatial modelling of widely distributed oriental-beech forests syntaxa in the Northwestern Caucasus

Folia Oecologica
For the first time in the Northwestern Caucasus, we applied the maximum entropy method (MaxEnt) to estimate the potential distribution of widespread oriental-beech forest syntaxa belonging to the alliance Myosotido dissitiflorae–Fagion orientalis ...

The Anthropocene and the End of Nuclear Disaster: Normalizing the Fukushima Nuclear Accident

American Anthropologist, EarlyView.
ABSTRACT This article places the concept of disaster in critical dialogue with that of the Anthropocene, which introduces new imaginaries that negatively affect the governance of crises like nuclear accidents. I argue that tropes surrounding the Anthropocene can depict certain events as apocalyptic calamities while also portraying other events as mere “

Land, Gendered Labor, and Empire‐Making in Central Sudan

American Anthropologist, EarlyView.
ABSTRACT This article offers an analysis of Gulf‐Arab and more specifically Emirati empire‐making in central Sudan, by focusing ethnographic attention on an Emirati‐owned farm in the Gezira region as a key site of capitalist extraction and imperial ambition.

Nicotinic Acid Restriction Enhances the Therapeutic Benefit of NAMPT Inhibition in Small‐Cell Lung Cancer Models

Cancer Science, EarlyView.
Dietary NA restriction converts the effect of NAMPT inhibition from cytostatic to cytotoxic in SCLC in vivo. ABSTRACT Small‐cell lung cancer (SCLC) is an aggressive malignancy with limited therapeutic options. We previously showed that nicotinic acid riboside (NAR) sustains NAD biosynthesis in vivo and compensates for NAMPT inhibition in SCLC models ...

Morphology‐based phylogeny of longhorn beetles (Coleoptera, Cerambycidae) aligns with phylogenomics and informs higher‐level systematics

Cladistics, EarlyView.
Abstract We present a morphology‐based backbone phylogeny of Cerambycidae beetles inferred by parsimony analyses using 77 adult characters scored for 101 species. This phylogeny is largely consistent with recent phylogenomic studies regarding key placements (e.g., Parandrini stat. rev. within Prioninae, Necydalini stat. rev.

A revised classification system of the marronoid clade of spiders (Araneae), based on dense sampling phylogenomics and comparative morphology

Cladistics, EarlyView.
Abstract The marronoid clade is a globally distributed, ecologically diverse group of spiders. It is an important faunal component in both natural and synanthropic environments, and even found in aquatic and extreme habitats such as desert salt flats. The systematics of the marronoid clade has been notoriously unstable due to the widespread character ...

Relaxed Steering towards Oriented Region Goals

, 2008
This paper extends the funnelling behavior to offer a low-cost flexible guidance of mobile entities towards a circular region goal with the guarantee of enforcing an orientation within a predefined tolerance interval. The key requirements are the same as the funnelling control, i.e.
