Seasonal trophic controls drive population variability in a foundational marine copepod

Scientific Reports
Understanding the trophic drivers of zooplankton population variability is critical for predicting ecosystem responses to climate change. In the Gulf of Maine, the copepod Calanus finmarchicus is a foundational species linking primary producers to higher

Patterns of understorey bird diversity across Amazonian forests: survey effort and range maps predict local species richness

Ecography, EarlyView.
Species diversity typically increases from higher to lower latitudes, but the regional‐scale variation along this geographic gradient remains unclear. It has been suggested that species diversity throughout Amazonia generally increases westward toward the Andes, but this pattern and its environmental determinants require further investigation for most ...

Studying interspecific population synchrony: current status and future perspectives

Ecography, EarlyView.
Interspecific population synchrony, or co‐fluctuations in the population dynamics and demographic parameters of different species, is an important ecological phenomenon with major implications for the stability of communities and ecosystems. It is also central in the context of biodiversity loss, as interspecific synchrony can influence how ecological ...

The scaling of seed‐dispersal specialization in interaction networks across levels of organization

Ecography, EarlyView.
Natural ecosystems are characterized by a specialization pattern where few species are common while many others are rare. In ecological networks involving biotic interactions, specialization operates as a continuum at individual, species, and community levels. Theory predicts that ecological and evolutionary factors can primarily explain specialization.

Powerful yet challenging: mechanistic niche models for predicting invasive species potential distribution under climate change

Ecography, EarlyView.
Risk assessments of invasive species present one of the most challenging applications of species distribution models (SDMs) due to the fundamental issues of distributional disequilibrium, niche changes, and truncation. Invasive species often occupy only a fraction of their potential environmental and geographic ranges, as their spatiotemporal dynamics ...

Alpine ungulates adjust diel activity to the natural return of wolves amid anthropogenic pressures

Ecography, EarlyView.
As wolves recolonise their historical range across Europe, ungulates face predation once more – but in landscapes profoundly altered by human activity. This shift raises crucial questions about their capacity to express adaptive antipredator behaviours.

An Ecosystem Model with Evolutionary Adaptive Trophic Structure

, 2013
Philip J. UnderwoodDoctorate of PhilosophyThe School of Environmental SciencesUniversity of East AngliaSeptember 2013 We live in an era of rapid change in ecosystems and their environments, that all scales up to the global. The contemporary view is that the interactions between life and the environment are bidirectional: the environment creates life ...

Deep refuges: the distribution of marine fish in warming subtropics

Ecography, EarlyView.
In light of global climate change, identifying critical marine habitats and conserving them is essential. Marine conservation planning recommends designating cooler habitats as marine protected areas. The ‘deep‐reef refugia' hypothesis suggests that deeper, suitable habitats may allow species to undergo the evolutionary changes necessary to adapt to ...

Impacts of large herbivores on mycorrhizal fungal communities across the Arctic

Ecography, EarlyView.
Mycorrhizal fungi play an integral role in nutrient and carbon cycling in soils, which may be especially important in the Arctic, one of the world's most soil carbon‐rich regions. Large mammalian herbivores can influence these fungi through their impacts on vegetation and soil conditions, however the strength and prevalence of these interactions in the
