‘The most advanced outpost of cultivation’: palynological evidence for cereal agriculture and population resilience in a marginal upland environment

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Upland farming in Europe is frequently assumed to have been limited and precarious, despite relict spade‐dug ridges providing firm evidence of past crop growing. Direct evidence for crop types in post‑Medieval to Modern (~since 1500 CE) uplands is rare; yet, in Ireland, relict spade‐dug ridges that date to this period are commonly interpreted ...

Gene turnover in the common ancestor of all C4 grasses

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Understanding how plants evolve more efficient photosynthesis is important in a warming world where improving crop productivity and resilience is a global priority. By generating the first reference genomes for an early‐diverging group of grasses called the Aristidoideae, we were able to reconstruct the genetic makeup of the last common ancestor of all

Inferring hypothesis-based transitions in clade-specific models of chromosome number evolution in sedges (Cyperaceae).

open access: yesMolecular Phylogenetics and Evolution, 2019
Large-scale changes in chromosome number have been associated with diversification rate shifts in many lineages of plants. For instance, several ancient rounds of polyploidization events have been inferred to promote genomic differentiation and/or ...

Biology, ecology, and conservation of the Italian hare Lepus corsicanus: a review

open access: yesWildlife Biology, EarlyView.
The Italian hare Lepus corsicanus, an endemic lagomorph of Italy, serves as a critical case study in evolutionary biology and conservation. Once taxonomically debated, modern genetic and morphological analyses confirm its status as a distinct Pleistocene lineage restricted to the central‐southern Italian Peninsula and Sicily.

Dietary and Ranging Behavior of Semi‐Free Ranging Lemur catta and Varecia rubra at Myakka City Lemur Reserve, Florida, USA

open access: yesZoo Biology, EarlyView.
Betsiboka, a female red ruffed lemur (Varecia rubra) eating Carolina redroot in the Tower forest. ABSTRACT Lemurs are severely threatened due to anthropogenic habitat loss and climate change. Therefore, understanding how lemurs adapt their diets to novel habitats is critically important for maintaining healthy wild populations and effectively managing ...

The Late Agricultural Development of Central Arabian Oases—Archaeobotanical and Archaeozoological Studies of the al‐Kharj Oasis

open access: yesArabian Archaeology and Epigraphy, EarlyView.
ABSTRACT While oasis settlements emerged during the Bronze Age in Eastern and Northern Arabia, the settlement process in Central Arabia was different. Excavations at al‐Yamāma—main ancient settlement of the al‐Kharj oasis (Riyadh Province, KSA)—suggest that the latter did not emerge before the second half of the first millennium BCE.

Changing climates and environments within the complex Middle to Late Pleistocene fill of an overdeepened valley at Niederweningen, Switzerland

open access: yesBoreas, EarlyView.
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 ...

Root structure syndromes of four families of monocots in the Middle Urals

open access: yesPlant Diversity, 2023
The present article tests the following general assumption: plant taxa with different specializations towards mycorrhizal interactions should have different root syndromes. Roots of 61 species common in boreal zone were studied: 16 species of Poaceae, 24
