‘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 ...

A new piece in the puzzle: The palaeoecological significance of bryozoans over 7000 years in Daidokutsu Cave (Okinawa, Japan)

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Submarine caves are cryptic, climatically sensitive habitats with long‐term ecological dynamics that are poorly understood. We present the first palaeoecological analysis of bryozoans from Daidokutsu Cave (Okinawa, Japan), based on a sediment core spanning approximately the last 7000 years.

Bulbophyllum weddellii (Orchidaceae) demonstrates foliar water uptake plasticity along Brazilian campos rupestres

open access: yesNordic Journal of Botany, EarlyView.
Phenotypic plasticity can facilitate species survival in a variety of conditions that are not possible with a fixed phenotype. Foliar water uptake (FWU), defined as the absorption of water through leaf surfaces, is an important mechanism contributing to plant water balance and drought tolerance in many species.

Ginkgo Biloba Extract Enhances Noncontact Erection in Rats: The Role of Dopamine in the Paraventricular Nucleus and the Mesolimbic System

open access: yes, 2012
Penile erection is essential for successful copulation in males. Dopaminergic projections from the paraventricular nucleus (PVN) to the ventral tegmental area (VTA) and from the VTA to the nucleus accumbens ( NAc) are thought to exert a facilitatory ...
