Pest and Host Associations That Transcend Time: Assessing the Impact of Climate Change on Grape Berry Moth (<i>Paralobesia viteana</i>) and Its Hosts <i>Vitis riparia</i> and <i>Vitis labrusca</i> in North America. [PDF]

open access: yesEcol Evol
This study predicted the potential geographic distribution of GBM and two of its host plants, Vitis labrusca and Vitis riparia, across the United States (U.S.) and Canada in the current time and under two climate change scenarios (SSP2–4.5 and SSP5–8.5) and periods (2021–2040 and 2041–2060) using the Random Forest algorithm.

Alluvial ridge morphology on avulsing rivers

open access: yesSedimentology, EarlyView.
ABSTRACT Alluvial ridges are built by preferential channel‐belt deposition and control river avulsions, yet a systematic analysis of their morphology has been missing. To address this gap, we analyse a globally distributed dataset of 8970 alluvial ridge flanks on 14 different rivers.

Cybianthus anthuriophyllus (Primulaceae), a new record for the flora of Colombia: distribution modeling and conservation assessment

open access: yesNordic Journal of Botany, Volume 2026, Issue 8, August 2026.
Cybianthus anthuriophyllus (Primulaceae) was previously known from eastern Ecuador and northern Peru. Here we document the first confirmed occurrences of this species in Colombia and develop a distribution model based on collections from the Andean–Amazonian foothills of Caquetá, Cauca, and Putumayo departments, in order to clarify its conservation ...
