Coastal pollution reduces genetic diversity of corals, reef resilience（图）
Coastal pollution genetic diversity coral reef resilience
2020/4/10
A new study published in the journal PeerJ by researchers at the University of Hawaii found that human-induced environmental stressors have a large effect on the genetic compositio...
Modern genetic sequencing tools give clearer picture of how corals are related（图）
modern genetic sequencing tools clearer picture corals
2017/9/5
The documentary “Chasing Coral,” released on Netflix in July, is a cinematic warning about how the bleaching of coral reefs may foreshadow how these marine animals will respond to climate change. Cora...
Marine reserves help preserve genetic diversity after impacts derived from climate variability: Lessons from the pink abalone in Baja California
Marine reserve Overfishing
2015/12/11
Genetic diversity is crucial for the adaptation of exploited species like the pink abalone
(Haliotis corrugata), faced with threats from climate change, overfishing and impacts
associated with aquac...
Understanding the connectivity of marine populations is vital for conservation and fisheries management, particularly for the strategic design of reserve systems. A recent proliferation of molecular a...
Genetic switch lets marine diatoms do less work at higher CO2
Genetic switch marine diatoms higher CO2
2015/6/18
Diatoms in the world’s oceans exhale more oxygen than all the world’s rainforests. These tiny drifting algae generate about 20 percent of the oxygen produced on Earth each year, and invisibly recycle ...
Local genetic adaptation to grazing pressure of the green algaDesmodesmus armatusin a strongly connected pond system
Local genetic adaptation grazing pressure the green alga Desmo desmus armatusin strongly connected pond system
2014/4/17
Dispersal potentially homogenizes genetic variation among populationsand thus may prevent local genetic adaptation. If selection gradients are strong and the selection responseefficient, however, loca...
Coexisting overwintering strategies inDaphnia pulex: A test of genetic differences and growth responses
Coexisting overwintering strategies in Daphnia pulexp A test of genetic differences growth responses
2014/4/16
We tested whether clones ofDaphnia pulexin a mesotrophic lake differ with respect to overwintering strategies:either surviving the winter as parthenogenetic females with reduced metabolism in pelagic ...
Genetic and environmental factors influence survival and hatching of diapausing eggs
environmental factors Genetic diapausing eggs
2014/4/16
To test the hypothesis that variation in hatching and survival of Daphnia dormant eggs is fostered by genetic
differences among populations, rather than system-specific availability of environmental ...
Life history, ecology and the biogeography of strong genetic breaks among 15 species of PaciWc rockWsh, Sebastes
Life history ecology
2015/12/11
Strong genetic change over short spatial scales
is surprising among marine species with high dispersal
potential. Concordant breaks among several species signals
a role for geographic barriers to d...
Mitochondrial and Nuclear Genetic Variation across Calving Lagoons in Eastern North Pacific Gray Whales (Eschrichtius robustus)
cetacean microsatellite population structure
2015/12/11
Accurate knowledge of population structure in cetaceans is critical for preserving and managing breeding habitat,
particularly when habitat is not uniformly protected. Most eastern gray whales return...
Colonization patterns of Nematoda on decomposing algae in the estuarine environment: Community assembly and genetic structure of the dominant species Pellioditis marina
Colonization patterns of Nematoda estuarine environment: Community assembly genetic structure dominant species Pellioditis marina
2014/4/22
We performed a field experiment in the Westerschelde Estuary (The Netherlands) to characterize the colonization dynamics of nematodes in relation to the proximity of a source population and to local e...
Spring bloom development, genetic variation, and population succession in the planktonic diatom Ditylum brightwellii
Spring bloom development genetic variation population succession planktonic diatom Ditylum brightwellii
2014/5/4
We determined spatial and temporal variation in abundance, distribution, and genetic composition of the planktonic marine diatom Ditylum brightwellii in 21 water samples collected between February and...

A comparative population genetic study calanoid freshwater copepods
2014/4/23
We examined patterns of genetic isolation-by-distance in two sister species of freshwater copepods, Eudiaptomus
graciloides and Eudiaptomus gracilis, using the polymorphism of microsatellite markers....
