A Middle and Late Devensian sequence from the northern part of Kents Cavern (Devon, UK)

open access: yesJournal of Quaternary Science, EarlyView.
Abstract 1920s/30s excavation of a Middle Devensian sequence in the northern part of Kents Cavern recovered important Late Middle and Early Upper Palaeolithic archaeological material, including Britain's oldest known Homo sapiens remains. Questions remain about this material, including how it came to be in the cave.

Mixed evidence for disturbance‐mediated apparent competition for declining caribou in western British Columbia, Canada

open access: yesThe Journal of Wildlife Management, EarlyView.
Investigating the decline of a caribou population in central British Columbia, we found that 1) recent wildfires were a stronger draw for primary ungulate prey than cutblocks, 2) most predators were associated with primary prey but had mixed responses to disturbance, and 3) caribou used cutblocks, potentially increasing their risk.

Empowering Family Farming Through Participatory Mapping, Land Suitability Analysis and Sustainable Practices

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT This study integrated participatory mapping methods and land suitability analysis to address sustainability challenges in family farming in Guerrero, Mexico. Through workshops with farmers, we identified the types of family farming and their problems, such as pests, diseases, low productivity, land degradation, and lack of resources.

Runoff and Sediment Response to Different Fire Intensities in a Hyrcanian Mixed Broadleaved Forest Ecosystem

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Wildfires are increasingly recognized as a critical driver of ecosystem degradation, with post‐fire hydrological and soil impacts posing significant threats to biodiversity, water quality, and long‐term land productivity. In fire‐prone regions, understanding how varying fire intensities exacerbate runoff and erosion is essential for guiding ...

Continental‐scale seston stoichiometry reveals fundamental constraints on the elemental composition of particles transported by streams

open access: yesLimnology and Oceanography, EarlyView.
Abstract Suspended particulate matter, or seston, represents an understudied flux of carbon (C), nitrogen (N), and phosphorus (P) in river networks. Here, we summarize riverine seston C : N : P stoichiometry data from 27 streams and rivers sampled regularly from 2014 to 2022 across the United States by the National Ecological Observatory Network (NEON).

Phenology in winter‐deciduous relict Mediterranean forests as a tool to understand their adaptation to climatic seasonal cycles

open access: yesNordic Journal of Botany, EarlyView.
Winter deciduous forests signify a relict ecosystem that survives restricted to microclimatic zones of high mountains in the western Mediterranean Basin and they are well represented in the southern Iberian Peninsula (Sierra Nevada, Spain). Given the scarce knowledge of their phenological behaviour, the aim of this work was to obtain the annual ...

Description of pistillate flowers and conservation status of two species of Mollinedia (Monimiaceae, Laurales) from the Brazilian Atlantic forest

open access: yesNordic Journal of Botany, EarlyView.
Mollinedia is one of the richest genera of Monimiaceae, with approximately 60 species. In Brazil, 46 species of the genus occur, most of them in the Atlantic Forest. Mollinedia dolichotricha and Mollinedia ruschii are species endemic to the Atlantic Forest and described in the last decade.
