The tip of the tail: molecular identification of seahorses for sale in apothecary shops and curio stores in California
Molecular forensics
<
2015/12/11
Millions of seahorses a year are traded internationally, with many eventually sold at retail shops as
curios, as aquarium pets, and especially for use in traditional medicine. The entire genus is now...
Extensive sympatry, cryptic diversity and introgression throughout the geographic distribution of two coral species complexes
Acropora, ryptic species hybridization
<
2015/12/11
The identification of species is one of the most basic, and yet critically important, issues
in biology with far-reaching potential implications for fields such as biodiversity
conservation, populat...
Populations of Symbiodinium muscatinei Show Strong Biogeographic Structuring in the Intertidal Anemone Anthopleura elegantissima
Symbiodinium muscatinei Anthopleura elegantissima
<
2015/12/11
Among temperate cnidarian symbioses, the
partnership between the intertidal anemone Anthopleura
elegantissima and its dinoflagellate and chlorophyte symbionts is one of the most well character...
Whole-Genome Positive Selection and Habitat-Driven Evolution in a Shallow and a Deep-Sea Urchin
positive selection dN/dS
<
2015/12/11
Comparisons of genomic sequence between divergent species can provide insight into the action of natural
selection across many distinct classes of proteins. Here, we examine the extent of positive se...

2015/12/11
Marine protected areas (MPAs) that excludefishing have been shown repeatedly to enhance the abundance, size, and diversity of species.
These benefits, however, mean little to most marine ...
USING ISOLATION BY DISTANCE AND EFFECTIVE DENSITY TO ESTIMATE DISPERSAL SCALES IN ANEMONEFISH
Amphiprion clarkii continuous population
<
2015/12/11
Robust estimates of dispersal are critical for understanding population dynamics and local adaptation, as well as for successful
spatial management. Genetic isolation by distance patterns hold clues ...
Are Antarctic minke whales unusually abundant because of 20th century whaling?

2015/12/11
Severe declines in megafauna worldwide illuminate the role of top predators in
ecosystem structure. In the Antarctic, the Krill Surplus Hypothesis posits that the killing
of more than 2 million larg...
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...
The Tara Oceans expedition harkens back
to 18th-century sailing voyages that explored

The Secret Life of Marine Mammals: Novel Tools for Studying Their Behavior and Biology at Sea
Marine Mammals Behavior and Biology
<
2015/8/19
Given the interest by both the lay and scientific communities, it is surprising how little is known about the open ocean ecology of marine mammals. Their patchy distribution and low abundance leads to...
The last 10–15 years have seen major changes in our views of marine planktonic food webs, primarily from the realization that prokaryotic microorganisms and small eukaryotes are responsible for a sign...
The concept that ocean fronts are important features in oceanic biology has a long history, as noted by the quotations cited above. The example of a functional understanding of fronts provided by a co...
Biological Considerations in Marine Enclosure Experiments: Challenges and Revelations
Estuary system biological disciplines
<
2015/8/17
Logistical considerations have usually dictated that components of estuarine systems be considered in isolation from one another whether in the laboratory or field. Hence, biological disciplines usual...
Grazing and Zooplankton Production as Key Controls of Phytoplankton Production in the Open Ocean
Coast phytoplankton pigment waters physical oceanography

2015/8/17
Thanks to NASA's Coastal Zone Color Scanner (CZCS, 1978-1986), nearly ocean-wide coverage of the distribution of phytoplankton pigment in the upper part of the euphotic zone and, in effect, in the mix...
