Tree Squirrels Selectively Disperse High‐Quality Acorns Away From Tree Trunks

Integrative Zoology, EarlyView.
Acorn quality and squirrel feeding behavior significantly structured spatial dispersal patterns of two Californian oak species. Non‐infested acorns were preferentially selected for embryo excision and dispersed farther than infested ones. Acorns were fully consumed near tree trunks, signaling rapid feeding in safe refuges, whereas non‐eaten, partially ...

Offspring Defensive Investment Covaries With Brood Value in a Female Cobweb Spider

Integrative Zoology, EarlyView.
We performed a thorough field investigation on the web architectures of Campanicola campanulata to research its cobweb architecture variation under the condition of whether it carried egg sacs, in order to test the theory of its brood value. Our results demonstrate that retreat construction in female cobweb spiders is modulated by brood value.

Morphotype Bias, Morph Specific Recruitment and No Elevation‐Life History Relation in High Altitude Mesquite Lizard Populations

Integrative Zoology, EarlyView.
Site‐level differences in population growth (λ) and phenotype frequencies. Mountain silhouettes represent the three study sites. Morph relative abundances are shown in the colored vertical bar. Point estimates and confidence intervals of λ for each site are displayed below, with the dashed line marking the threshold for demographic stability (λ = 1 ...

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

Boreas, 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 ...

Adiponectin promotes AMPA receptor trafficking and enhances excitatory synaptic transmission at hippocampal synapses via AMP‐activated protein kinase signalling

British Journal of Pharmacology, EarlyView.
Background and Purpose Peripherally derived adiponectin crosses the blood–brain barrier and targets severa0l brain regions. Adiponectin receptors are highly expressed in the hippocampus, and play a pro‐cognitive role as adiponectin markedly influences the functioning of hippocampal synapses.

Potentiation effects of the positive allosteric modulator PTC‐174 on NMDA receptors in neonatal male rat substantia nigra dopaminergic neurons

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Positive allosteric modulators bind to secondary binding sites on the receptor and alter receptor conformation and activation, changing agonist potency and efficacy. PTC‐174 is a novel NMDA receptor positive allosteric modulator that particularly enhances activity of receptors containing GluN2C or GluN2D subunits.

‘I like to dance with the flowers!’: Exploring the possibilities for biodiverse futures in an urban forest school

Children &Society, EarlyView.
Abstract This article explores the ways in which ‘forest school’, an educational approach where children engage in creative and play based activities in a ‘natural’ environment, can contribute towards Sustainable Development Goal 15 (SDG 15) by promoting sustainable use of terrestrial ecosystems and by helping address biodiversity loss. Drawing on data

A First Indication That Rainforest Vine Proliferation Does Not Enhance Predator–Prey Interactions on the Forest Floor

Entomologia Experimentalis et Applicata, EarlyView.
Vine proliferation is a widespread consequence of tropical forest disturbance, yet its effects on ground‐level predator–prey interactions remain poorly understood. Using plasticine caterpillars deployed on the rainforest floor in north Queensland, Australia, we show that overall predation rates were unaffected by vine‐to‐tree ratio. Instead, fine‐scale
