An AI‐driven soil extractor for high‐throughput measurement of soil microarthropod taxon densities using live individuals

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Soil invertebrates play a key role in ecosystem functioning, yet their monitoring remains constrained by labour‐intensive extraction and taxonomic identification procedures. Consequently, large‐scale and high‐frequency assessments of soil biodiversity remain difficult despite increasing demand for standardized monitoring tools.

Bridging the Late Antique Gap in Northwest Arabia: New Archaeological Evidence on the Occupation of Wādī al‐Qurā (al‐ʿUlā [AlUla], Saudi Arabia) Between the Third and Seventh Centuries CE

open access: yesArabian Archaeology and Epigraphy, EarlyView.
ABSTRACT In 2019, the Dadan Archaeological Project (CNRS/RCU/AFALULA) identified a Late Antique village 1 km south of ancient Dadan in the al‐ʿUlā valley (northwest Saudi Arabia). Three excavation seasons at this site (2021–2023) have uncovered a massive building constructed in the late third or early fourth cent.

Breeding Dispersal of Baltic Dunlins Is Not an Adaptive Response to Unpredictable Nest Flooding

open access: yesAnimal Conservation, EarlyView.
Flood‐related nest losses of the Baltic dunlin (Calidris alpina schinzii) have drastically increased over the past two decades. Using 20 years of reproductive data from 184 individuals, we found that between‐year and within‐site dispersal tended to increase following nest failure in males.

Modern pollen rain of an upland area: implications of pollen dispersal for interpreting palaeoenvironmental records

open access: yesBoreas, EarlyView.
A long‐term perspective on landscape evolution is critical for understanding past land‐use activity, land cover–climate feedbacks and, notably, for establishing a factual basis for conservation. Fossil pollen analysis provides a means to achieve this. Biases pertaining to pollen productivity, pollination processes and basin size, however, mean there is

The last glacial cycle in western Norway—extensive MIS 5d glaciation, multiple glacial advances and LGM glacial advance phases

open access: yesBoreas, EarlyView.
Raised marine MIS 5c sediments evidence extensive preceding (5d) glaciation in western Norway. This is the first out of five (or six) major Weichselian glacier advances that seem to correspond to North Atlantic sea surface cooling periods. Till beds capping the marine sediments show stages of pre‐LGM advance and subsequent retreat.

Physiological Host Range of the Tachinid Istocheta aldrichi, a Potential Biological Control Agent for the Japanese Beetle in Europe

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
This study provides the first laboratory assessment of the physiological host range of Istocheta aldrichi, a candidate biological control agent for Popillia japonica in Europe. In sequential no‐choice tests with 14 European scarab beetles, the parasitoid oviposited on six species but successfully developed only in the two Rutelinae Anomala vitis and ...
