Evaluating land–sea linkages using land cover change and coral reef monitoring data: A case study from northeastern Puerto Rico

Remote Sensing in Ecology and Conservation, EarlyView.
Land cover change that leads to increased nutrient and sediment runoff is an important driver of change in coral reef ecosystems. In this study, we combined satellite remote sensing and field monitoring to assess concomitant changes in watershed land cover and coral cover in northeastern Puerto Rico in 2000–2015.

Metabolomic profiles of stony coral species from the Dry Tortugas National Park display inter- and intraspecies variation

mSystems
Coral reefs are experiencing unprecedented loss in coral cover due to increased incidence of disease and bleaching events. Thus, understanding mechanisms of disease susceptibility and resilience, which vary by species, is important.

Alarming the impacts of the organic and inorganic UV blockers on endangered coral's species in the Persian Gulf: A scientific concern for coral protection

Sustainable Futures, 2020
Coral reefs provide many benefits to the society, including ecological nest for aquatic species, medicine ingredient, and protection of coastlines from flooding and storms.

Scale dependence in remotely sensed biodiversity: Leveraging continental‐scale imaging spectroscopy from the National Ecological Observatory Network

Remote Sensing in Ecology and Conservation, EarlyView.
Imaging spectroscopy enables large‐scale biodiversity assessment, yet spectral diversity metrics are scale dependent. Across 15 NEON ecosystems, we find that spectral richness increases sub‐linearly from 3600 m2 to 4 km2, whereas spectral divergence shows weak or inconsistent scaling with area, underscoring the importance of scale‐aware interpretation ...

The energetic consequences of oxygen fluxes in a coral reef fish

Functional Ecology, EarlyView.
Abstract Ocean warming elevates metabolic rates in marine ectotherms but often constrains energetic resources, causing an imbalance between supply and demand. Transient hypoxia is near‐ubiquitous across the world's coral reefs and may exacerbate this imbalance, yet its effects on the energetics of reef fishes remain poorly understood. In this study, we

Effects of temperature and browning on the functional response of a freshwater top predator

Journal of Animal Ecology, EarlyView.
This study explores for the first time how temperature and browning affect the functional response of a freshwater piscivore, the northern pike. The authors find surprisingly weak effects of browning, challenging visual foraging theory. Pike displayed a rare dome‐shaped functional response in cold clear water, potentially driven by seasonal changes in ...

Stony corals (Scleractinia) from the Marías Islands, Mexican Pacific

Ciencias Marinas, 2006
Recent studies performed off the Pacific coast of Mexico have shown a large number of reefs or coral patches in the region, but information is still lacking for some areas.

Stony coral tissue loss disease indirectly alters reef communities

Science Advances
Many Caribbean coral reefs are near collapse due to various threats. An emerging threat, stony coral tissue loss disease (SCTLD), is spreading across the Western Atlantic and Caribbean. Data from the U.S. Virgin Islands reveal how SCTLD spread has reduced the abundance of susceptible coral and crustose coralline algae and increased cyanobacteria, fire ...

The Savage Worlds of Henry Drummond (1851–1897): Science, Racism and Religion in the Work of a Popular Evolutionist

Journal of Religious History, EarlyView.
Abstract The savage was a familiar as well as deeply problematic figure in late‐Victorian literary and scientific imaginaries. Savages provided an unstable but capacious and flexible signifier to explore human development and human difference, most often in ways that followed a disturbing racial logic.

As above, so below: A perspective into the application of land‐forest monitoring methods for the assessment of marine animal forests

Methods in Ecology and Evolution, EarlyView.
Abstract Marine animal forests (MAFs) are benthic ecosystems dominated by vertically structuring filter‐ and suspension‐feeders. As terrestrial forests, they are considered biodiversity hotspots, forming canopies, serving as a refuge, nursery, reproduction and feeding shelters for many species.
