Early Longitudinal Brain Network Changes in Huntington's Disease Before Clinical Motor Onset

Movement Disorders, EarlyView.
Abstract Background Longitudinal studies of seed‐based functional connectivity (SBFC) in young adult Huntington's disease gene‐expanded (HDGE) individuals are rare, and none, to our knowledge, have examined adult cohorts decades from predicted clinical motor diagnosis.

Calibration‐Free Estimation of Cerebrovascular Reactivity From Resting‐State BOLD fMRI Using Reconstructed Respiratory Fluctuations

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Cerebrovascular reactivity (CVR) provides an important index of vascular health and is conventionally quantified using a hypercapnic gas or breath‐hold challenge in conjunction with blood‐oxygen‐level‐dependent functional magnetic resonance imaging (BOLD‐fMRI).

Greater future range expansions in alien than native ant species

Oikos, EarlyView.
There is growing concern that many species may not be able to track suitable conditions under climate change and suffer range contractions as a result. At the same time, alien species introduced to novel geographic ranges are often assumed to benefit from climate change.

A plant–pollinator invasional meltdown: the Japanese pagoda tree Styphnolobium japonicum facilitates the invasion of the giant resin bee Megachile sculpturalis

Oikos, EarlyView.
An invasional meltdown can occur when a non‐native species facilitates the spread of another non‐native species in the invaded area, increasing its likelihood of survival or its ecological impact. Plant–pollinator systems pose an exceptional study system to test this concept, which remains poorly known.

The impact of COVID‐19 on public perceptions of wild meat in Central Africa

People and Nature, EarlyView.
Abstract Wild meat is a significant source of food and income generation in Central Africa. However, there is little knowledge of how the assumed link between COVID‐19 and wild meat consumption has been discussed by the media and received by the public. In this study, we conducted media content analysis of 264 articles published in 2019–2020 related to

Bushmeat consumption frequency and preferences among rural households in a West African savanna landscape: Implications for food security and conservation

People and Nature, EarlyView.
Abstract The drivers of consumer demand for bushmeat are relatively well studied in tropical forest systems, but much less so in savanna areas. This is important because differing ecological and socio‐economic conditions lead to different factors affecting the relationship between local communities and their natural resources.

Biodiversity and bird welfare in evaluation of tourism impact and sustainability in arid environment

People and Nature, EarlyView.
Abstract Nature‐based tourism is rapidly expanding in arid regions, raising concerns about its long‐term sustainability and potential impacts on biodiversity. However, empirical evidence evaluating its effects on both species diversity and animal welfare remains limited.

The shared benefits of fallen fruits: A novel mechanism stabilizing a nursery pollination mutualism between Sambucus and kateretid beetles

PLANTS, PEOPLE, PLANET, EarlyView.
Understanding how cooperative interactions remain stable matters for biodiversity because many plants rely on specialist insects that can also impose reproductive costs. We studied the interaction between Sambucus sieboldiana and seed‐consuming Heterhelus beetles through detailed field observations and pollination experiments.

Climate‐driven intraspecific shifts in seed germination phenology: Consequences for native temperate woodland restoration and regeneration

PLANTS, PEOPLE, PLANET, EarlyView.
As climate change alters seasonal patterns, temperate tree populations face a growing risk of phenological mismatch, where seed dispersal and germination no longer align with favourable conditions for survival. This study predicted how warming by the end of the century will affect seed dormancy breaking and germination in populations of three UK tree ...

A new generalized linear model (GLM) framework for analysing categorical data; application to plant structure and development.

, 2013
Le but de cette thèse est de proposer une nouvelle classe de GLMs pour une variable réponse catégorielle structurée hiérarchiquement, comme une variable partiellement ordonnée par exemple. Une première étape a été de mettre en évidence les différences et les point communs entre les GLMs pour variables réponses nominale et ordinale.
