Seascape configuration determines spatial patterns of seabird‐vectored nutrient enrichment to coral reefs

Ecography, EarlyView.
Pelagic‐feeding seabirds deliver nutrient subsidies that enhance the productivity, biodiversity, and resilience of terrestrial and marine ecosystems, particularly in nutrient‐poor tropical environments. However, the biogeophysical variables governing the fluxes of these nutrients within and among interconnected ecosystems remain poorly understood.

The time of acquisition of multispectral predictors matters: the role of seasonality in bird species distribution models

Ecography, EarlyView.
Species distribution models (SDMs) analyse the relationships between species occurrences and environmental predictors. Their efficacy largely depends on the selection of ecologically relevant predictors, with remote sensing (RS) data being one of the most commonly used sources. The usability of multispectral predictors is influenced by temporal changes

Wild bees and landcover: bee species' body size does not predict the scale of effect, but bee phenology predicts association with landcover type

Ecography, EarlyView.
Habitat is a key aspect of any species' niche and can affect populations at multiple spatial scales. Basic ecology and effective conservation thus require an understanding of which habitats matter and at what scales. Yet, habitat studies are rarely scale‐optimized, and what determines the scale(s) at which populations are affected by surrounding ...

Effects of phytoplankton species distribution on particulate organic carbon dynamics along a coastal gradient

Ecography, EarlyView.
Phytoplankton communities affect carbon dynamics worldwide, strongly influencing the quality and quantity of organic carbon in coastal ecosystems. Yet, we still know little about the impacts of changing phytoplankton community composition on the potential carbon pathways in estuaries and coasts.

Where do we expect to find deep plant roots?

Ecography, EarlyView.
Plant roots have been observed up to 70 m in depth – what would compel a plant to root so deeply? Earlier work shows that the climate, soil and drainage all affect rooting depth, but with conflicting results. For example, both the deepest and shallowest roots are found in arid regions.
