Since the mid-1950s, population outbreaks at densities four to six times greater than normal have occurred at the same time in places such as Hawaii, Tahiti, Panama, and the Great Barrier Reef. The result has often been the loss of a fifty percent to nearly one hundred percent of the ...
Ongoing ascidian population monitoring can provide a comprehensive understanding of ascidian dynamics whilst also providing insight of theimpact of anthropogenic stressors on benthic communities. Together, this can aid in informing management and conservation strategies for subtropical reefs.Eckhardt, Sh...
Although gonads occur in some colonies throughout the year, there are clear seasonal differences both in the number of reproductive colonies within the population and in colony fecundity. Male gametes are spawned monthly around the time of the full moon. The abundance and maturity of brooded ...
thereby increasing the frequency of thermal tolerance genes in the remaining population. As such, genetic adaptation in certain species may have influenced increases in thermal tolerance of the wider coral assemblage. Acclimatisation of coral colonies over the past decade may have also contributed to ...

Firstly, the coral-population models were particularly sensitive to the intensity of temperature anomalies (ε). Coral bleaching occurs during the most severe thermal-stress events10when summer temperatures are exacerbated by climatic phenomenon, particularly El Niño events; although recently, thermal-st...
Schizophrenia as a long-term outcome of pregnancy, delivery, and perinatal complications: a 28-year follow-up of the 1966 north Finland general population ... The 1966 North Finland general population birth cohort was studied to determine whether abnormalities during pregnancy, delivery, and the neo...
Populations of the scleractinian coral Madracis pharensis show great similarity over both spatial (between islands) and temporal (>30 yrs) scales on two islands of the Netherlands Antilles. After a growth phase, population structure becomes stable within five years after the start of settlement. At...
The project team deployed solar-powered buoys on the sea surface, under which underwater sensors were hung at different depths to measure environmental data, including weather conditions, water quality and nutrients, and the population distribution and behavior of marine life. The data is sent in ...
Its young age together with strong natural pressures (e.g. episodic austral and cyclonic swells) (Cordier et al., 2012) and higher human impacts (island population ~850,000) could explain the lower abundance and smaller size of the coral colonies found there. In contrast, New Caledonian reef...
