Predicting global habitat suitability and invasion risks of the red gum lerp psyllid Glycaspis brimblecombei under current and future climates

open access: yesAgricultural and Forest Entomology, EarlyView.
Ecological niche modelling identified highly suitable habitats for Glycaspis brimblecombei across tropical, subtropical and temperate regions. Future climate projections indicate a moderate contraction of suitable areas, with persistence of core climatic suitability. Model performance was robust (AUC = 0.880; TSS = 0.634; CBI = 0.803), with temperature

Climatic factors, landscape composition and host plant traits co‐drive fruit infestation of unmanaged walnut trees by the invasive pest fly Rhagoletis completa (Cresson, 1929) (Diptera: Tephritidae)

open access: yesAgricultural and Forest Entomology, EarlyView.
The study examined multiscale factors influencing walnut fruit infestations by the invasive pest fly Rhagoletis completa. Infestation rates increased with fruit size, host tree abundance, grasslands, hedgerows and temperatures, but decreased with anthropogenic habitats and heavy spring rainfall.

Rulers on the road: Itinerant rule in the Holy Roman Empire, AD 919–1519

open access: yesAmerican Journal of Political Science, EarlyView.
Abstract Itinerant rule, rule exercised through traveling, was a common yet insufficiently researched, premodern form of governance. Studying the determinants of ruler itineraries in the Holy Roman Empire, AD 919–1519, we argue that rulers' visits targeted “marginal” elites.

Optimizing high-resolution multi-view drone imaging for detecting foreign grains in gluten-free oat production fields [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
To reduce the high cost of manually detecting and removing gluten-containing grains from oat crops, drone imaging and deep learning can be used to automate the detection process.

Urban inequalities and marginalization of the Social and Solidarity Economy: A comparative analysis in the Sants‐Montjuïc district in Barcelona

open access: yesAnnals of Public and Cooperative Economics, EarlyView.
Abstract This article examines how urban inequalities influence the Social and Solidarity Economy (SSE) through a study of two Barcelona neighbourhoods. It evaluates the limitations of SSE promotion policies implemented between 2016 and 2024, focusing on their impact on diversifying socio‐enterprise initiatives and fostering cooperative ecosystems with

A Survey of Methods for Constructing 3D Urban Models From Point Clouds

open access: yesComputer Graphics Forum, EarlyView.
The survey outlines a general process for constructing 3D models from point clouds and categorizes the methods based on their use of templates, basic surface primitives, hybrid approaches, or linear primitives. Additionally, the survey reviews the datasets and benchmarks that are essential for testing and training the developed methods.

Effects of climate change on marine biodiversity on the western Atlantic coast

open access: yesConservation Biology, EarlyView.
Abstract The current climate crisis, driven by greenhouse gas emissions, threatens global biodiversity, including that in marine ecosystems. However, projections for the western Atlantic Ocean that jointly quantify species richness and endemism while accounting for spatially biased and incomplete occurrence data remain limited.

Reconnaissance‐Scale Methods for the Identification of Groundwater Discharge to Streams

open access: yesGroundwater Monitoring &Remediation, EarlyView.
Abstract Identifying groundwater discharge locations is critical for understanding and monitoring groundwater contributions to streams in terms of water quantity and quality. Streams and rivers are under increasing strain from factors, including increased urbanization, agricultural land use, groundwater extraction, and climate change, which can alter ...
