Decoupling climate and human impacts on the nitrogen cycle during the Irish Bronze Age
ABSTRACT Disentangling climate variability and human activity in past nitrogen cycling is key to understanding ecosystems. Previous studies in Ireland observed a widespread, permanent shift in terrestrial nitrogen cycling during Later Prehistory, potentially linked to intensifying land‐use.

ABSTRACT Victoria Cave, north Yorkshire, England, contains a long sequence of Pleistocene clastic sediments and calcite flowstones. Earlier work, using U–Th dating, established that the flowstone units formed in interglacial stages corresponding to Marine Isotope Stages (MIS) 13, 11, 9, 7 and 5.

Re-evaluating the Systematics of Dendrolycopodium Using Restriction-Site Associated DNA-Sequencing
The genus Dendrolycopodium (Lycopodiaceae) includes four to five species across North America and East Asia. Species identification in Dendrolycopodium is difficult due to limited or inconsistent characters.

A new species of Lentibulariaceae, Pinguicula brendae Rodríguez‐Ramírez, H.Shimai & A.R. Andrés‐Hernández, is described based on its unique morphological characteristics. This species is restricted to limestone rock walls in the San Bartolo Tutotepec municipality, central‐eastern Hidalgo, Mexico, where it inhabits a single locality on vertical, north ...

Malycorins A-C, New Lycopodium Alkaloids from Lycopodium phlegmaria
A novel C(19)N-type Lycopodium alkaloid, malycorin A (1) consisting of a serratinane skeleton with 2-propanol unit has been isolated from the club moss Lycopodium phlegmaria, together with two new C(16)N-type alkaloids, malycorins B (2) and C (3), and the structures and relative stereochemistry were elucidated on the basis of spectroscopic data.

Glacially overdeepened valleys in the northern Alpine Foreland preserve Middle to Late Pleistocene sedimentary sequences that may serve as valuable archives for reconstructing past environmental changes in response to shifts in climate. This study presents a multidisciplinary analysis of two sediment cores from the overdeepened Wehntal Valley at ...

Palynological records are central to the biostratigraphic subdivision of the Late Pleistocene in central Europe. Yet many interglacial and interstadial phases—such as the Eemian, Brörup and Odderade—remain only poorly constrained in time due to limited numerical dating.

Woodland caribou habitat restoration using lichen transplants: insights from a 24‐year trial
Abstract Introduction Lichens are crucial components of many ecosystems and serve as a key winter food source for caribou. In forest‐harvested block reclamation, the focus tends to be on replanting trees and shrubs, often overlooking lichens. Objectives This study examined the effect of different transplanting methods on the success of lichen ...
