Effect of ocean acidification on shellfish depends on other stressors
Santa Cruz, Calif. (UPI) May 9, 2016 -
On the dinner table, acid and shellfish pair nicely - in the ocean, not so much.
Determining the exact effects of ocean acidification on shellfish has proven difficult, however. Though plummeting pH levels have been blamed for shellfish die-offs, the correlations have appeared inconsistent.
New research suggests the response of shellfish to ocean acidification is dependent on a ...

A filter that shaped evolution of primates in Asia
Beiging, China (SPX) May 09, 2016 -
By studying fossils from southern China, scientists have gained insights into how primates in Asia evolved to resemble the array seen today. The results suggest that a distinct period marked by cooler weather served as a filter of sorts in Asia, altering the makeup of primates there to reflect fewer anthropoids (monkeys and apes) and more strepsirrhines, a suborder of primates that includes lemu ...

Drawing the genetic history of Ice Age Eurasian populations
Beijing, China (SPX) May 09, 2016 -
Not much is known about the genetics of Eurasian history before the introduction of farming. One of the major questions is how climatic fluctuations influenced the population history of Eurasia and to what extent changes in material cultures correspond to movements of people.
A research team led by Prof. FU Qiaomei from the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) ...

New evidence connects dung beetle evolution to dinosaurs
Cleveland OH (SPX) May 09, 2016 -
Researchers have found an evolutionary connection between dinosaurs and dung beetles. An international team of scientists uncovered the first molecular evidence indicating that dung beetles evolved in association with dinosaurs. The findings place the origin of dung beetles (Scarabaeidae: Scarabaeinae) in the Lower Cretaceous period, with the first major diversification occurring in the middle o ...
