Building consistent time series night-time light data from average DMSP/OLS images for indicating human activities in a large-scale oceanic area

International Journal of Applied Earth Observations and Geoinformation, 2022
Human activities in the ocean have never been chronically and continuously investigated on a large scale. Night-time light (NTL) images collected by the Defense Meteorological Satellite Program/Operational Linescan System (DMSP/OLS) have been used as a ...

Coral bleaching responses in Sodwana Bay, South Africa [PDF]

, 2013
This study assessed the bleaching response (BR) of coral colonies within the central reef complex in Sodwana Bay, South Africa. Bleach surveys were conducted at 16 sites on 8 reefs over the period of 2007 to 2013. A total of 12 858 coral colonies from 30

Biogeography and change among regional coral communities across the western Indian Ocean [PDF]

, 2014
Coral reefs are biodiverse ecosystems structured by abiotic and biotic factors operating across many spatial scales. Regional-scale interactions between climate change, biogeography and fisheries management remain poorly understood.

Multimodal Locomotion in Insect‐Inspired Microrobots: A Review of Strategies for Aerial, Surface, Aquatic, and Interfacial Motion

Advanced Robotics Research, EarlyView.
This review identifies key design considerations for insect‐inspired microrobots capable of multimodal locomotion. To draw inspiration, biological and robotic strategies for moving in air, on water surfaces, and underwater are examined, along with approaches for crossing the air–water interface.

Environmental acclimatization of the relatively high latitude scleractinian coral Pavona decussata: integrative perspectives on seasonal subaerial exposure and temperature fluctuations

BMC Genomics
Background Coral reefs are being increasingly threatened due to global climate change. However, some coral species have shown strong tolerance despite living in marginal environments.

Contrasting patterns of mortality in Polynesian coral reefs following the third global coral bleaching event in 2016

, 2022
In 2016, many tropical corals worldwide were exposed to anomalously high temperatures due to one of the strongest El Niño events ever recorded. Bleaching impacts were reported on 23 islands within three archipelagos of French Polynesia (Tuamotu, Society ...

The future of coral reefs [PDF]

Proceedings of the National Academy of Sciences, 2001
Coral reefs, with their millions of species, have changed profoundly because of the effects of people, and will continue to do so for the foreseeable future. Reefs are subject to many of the same processes that affect other human-dominated ecosystems, but some special features merit emphasis: ( i
