Asymmetric Effects of Daytime and Nighttime Warming on Boreal Forest Spring Phenology

Remote Sensing, 2019
Vegetation phenology is the most intuitive and sensitive biological indicator of environmental conditions, and the start of the season (SOS) can reflect the rapid response of terrestrial ecosystems to climate change.

Quantitative genetics of multidimensional plasticity in spring phenology

, 2022
Changing environmental conditions cause changes in the distributions of phenotypic traits in natural populations. Adaptation to environmental conditions can occur via micro-evolution, and, likely more often, via phenotypic plasticity. Phenotypic plasticity, when heritable, itself also has the potential for a micro-evolutionary response to selection ...

The integrated reproductive response: the scope for seasonal phenotypic flexibility shapes reproductive outcomes across fish populations

Oikos, EarlyView.
Across north‐temperate environments, rapid environmental change has disrupted the seasonal life histories of resident organisms, decreasing the reliability of environmental cues. Flexible responses capable of buffering the effects of unpredictable environmental variation to defend performance and reproductive outcomes may thus be key to species‐ and ...

Drivers of spring migration phenology in Rocky Mountain elk

Scientific Reports
By migrating, ungulates take advantage of cyclical fluctuations in resources, which allows them to persist at greater population numbers than they would in the absence of these seasonal movements. We sought to identify the drivers of spring elk (Cervus canadensis) migration and evaluate how well individuals were able to optimize access to forage prior ...

Do good neighbours compensate for bad climate? The case of sessile oak Quercus petraea in phylogenetically distant neighbourhoods

Oikos, EarlyView.
Stressful climates threaten the performance of individuals and the survival of species, but individual performance also depends on biotic interactions with neighbours, so that ‘good' neighbours might in theory compensate for ‘bad' climates. However, what makes a good neighbour, and why, has been little studied.

Digital surveillance of animals and nature recovery

People and Nature, EarlyView.
Abstract Digital surveillance technologies (DSTs) are widely applied in nature recovery for their potential to generate novel data on species and ecosystems through digital tracking, automation (e.g. from hazardous locations) and from newly recruited citizen scientists.

Remote sensing and citizen science for habitat mapping: A machine learning approach to lowland heathland in Surrey, UK

People and Nature, EarlyView.
Abstract In a time of extensive global biodiversity loss, conservation efforts increasingly rely on high‐resolution, accurate, up‐to‐date habitat maps to guide decision‐making and strategic interventions. Many products have been developed in response, using machine learning (ML) methods to automate habitat classification, often relying on satellite ...

A walk in the park—Identifying healthy greenspaces using scents

PLANTS, PEOPLE, PLANET, EarlyView.
As urbanisation accelerates globally, access to nature is increasingly recognised as vital for public health and wellbeing. We captured and analysed plant‐emitted airborne ‘scent signatures’ across Oxford's urban greenspaces to assess their potential health relevance.

The pistil as a traffic light: Yellow‐to‐red color change likely influences pollinator visitation patterns in Saxifraga fortunei (Saxifragaceae)

PLANTS, PEOPLE, PLANET, EarlyView.
Flowers can communicate reproductive status to pollinators through visual cues. In Saxifraga fortunei, pistils often changed from yellow to red after pollination, and hoverflies and honeybees preferentially visited flowers with yellow pistils. This pattern suggests that a post‐pollination color shift confined to the pistil can reduce revisits to ...

Changes in Spring Arrival Times: Climate change and the phenology of spring bird migration [PDF]

, 2019
Climate change and weather affect the phenology of bird migration; however, specific climatological factors associated with these observed effects have only recently been described.
