Abstract In recent years, a few colonial marine invertebrates have shown intracolonial genetic variability, previously unreported phenomenon. Intracolonial variability describes the occurrence of more than single genotype within an individual colony. This can be traced back to two underlying processes: chimerism and mosaicism. Chimerism is fusion or individuals, whereas mosaicism mostly derives from somatic cell mutations. Until now, it remained unclear what degree ecologically important...
Abstract Genetic diversity is the basis for adaptation and therefore of primary scientific interest, especially in species that are threatened by anthropogenic challenges, e.g . climate change and/or pollution. Coral reefs among most but also diverse ecosystems have been studied quite extensively. So far, investigations focused on scleractinian corals while equally important reef builders, hydrozoans, less considered. Here we provide first study genotypic variability as well intra‐colonial...
Limited data pertaining to life history and population connectivity of the data-deficient southern stingray (Hypanus americanus) are available. To determine potential vulnerabilities their populations, this study aimed analyse movement patterns genetic variability. A stingrays encompassing nine sites around Cape Eleuthera, Bahamas, has been monitored using mark-recapture, spanning a 2.5 year period. Out 200 individual stingrays, more than third were encountered again. The home range females...
Abstract Information on diversity indices and abundance of individual species is crucial for the assessment ecosystem health, especially endangered ecosystems as coral reefs. The application environmental DNA (eDNA) to monitor biodiversity is, however, just beginning come into focus marine biologists. In this study, an eDNA metabarcoding approach seawater samples in three different reefs Koh Pha‐ngan, Thailand, was compared with simultaneously collected visual census data. addition,...
Abstract Polyp bailout is a drastic response to acute stress where coral coloniality breaks down and polyps detach. We induced polyp in Pocillopora acuta with heat tested for differential gene expression using RNAseq qPCR assay. Furthermore, we hypersalinity compared the results identify stressor-independent signals pathways active during bailout. Both stressors led onset of detachment vital polyps. observed activation microbe-associated molecular pattern receptors downstream signaling...
