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).

Seagrass species diversity in Tanzania based on morphological and molecular data

Nordic Journal of Botany, EarlyView.
Seagrass diversity along the Tanzanian coast has been documented mainly through morphology, with limited molecular reference data available for Tanzania and the wider Western Indian Ocean. This study combined morphological identification with nuclear ribosomal internal transcribed spacer (ITS) and plastid ribulose‐1,5‐bisphosphate carboxylase/oxygenase

Integrating and assessing metacommunity drivers of ecosystem function and resilience in benthic algal systems

Oikos, EarlyView.
Understanding the scales and mechanisms by which species composition interacts with ecosystem functions is critical for forecasting the effects of environmental perturbations on ecosystem services. However, the linkages between what regulates the ecosystem functions of dispersal‐capable networks of communities (metacommunities) and what regulates a ...

Dynamic response of communities and ecosystem functions to ecosystem engineering and multiple stressors in a marine mussel bed

Oikos, EarlyView.
Ecosystem engineers are crucial to the development of coastal ecosystem communities and functions. However, a better understanding of how environmental stressors affect ecosystem engineering and thereby influence communities and ecosystem dynamics is needed. We conducted an in situ experiment in a blue mussel Mytilus spp.

Forecasting the impact of food‐provisioning and other stressors on a marine top‐predator population

Oikos, EarlyView.
Wildlife tourism can alter animal behavior, affect vital rates and diminish population viability but its impact in the context of other human‐ and environmental disturbances, remain largely unstudied. Using simulation models and leveraging a robust long‐term dataset spanning eight years, we evaluated the contribution of wildlife feeding, in the context
