Disease-spreading mosquitoes could be decimated by preventing them from seeking out mates, suggests new research. Previous studies have shown that male mosquitoes are attracted to the sound of female wingbeats. Now scientists have discovered that a “fruitless” gene in the…
Using more appropriate brain indices and less error-prone statistical methods, the researchers showed that carnivores do exhibit a quantitative social brain relationship. More strikingly, carnivores map directly onto the primate socio-cognitive grades, dividing between loose sociality and bonded sociality in…
Rice University evolutionary biologist Scott Egan and his research team have unearthed a new species of tiger beetle, deemed Eunota houstoniana, honoring the Houston region where it predominantly resides. The study is published online in Nature Scientific Reports. "It is…
Integrating DNA barcoding with morphology, researchers have identified two new cryptic Niphargus amphipod species from springs in central Iran, revealing recent speciation hidden beneath near-identical appearances. Subject of Research: Cryptic species delimitation in groundwater amphipods of Iran using molecular and…
As a generalization of stage-based matrix models, integral projection models (IPMs) have been used to describe the size-based dynamics of wildlife and fisheries populations. Although some matrix models have explicitly included species interactions, few IPMs have expanded beyond single species,…
Using lineage tracing, high-resolution microscopy and immunohistochemistry, the team followed the interactions between the two germ layers as the POG was pushed onto the embryonic surface in bichir, gar and sturgeon embryos. The results reveal that the three species achieve…
Since our last update, the NOAA Ship Henry B. Bigelow has made excellent progress. We are now approaching our 63rd station, about 10 miles south of Long Island. We have completed 59 bongo tows and 14 Conductivity Temperature Depth rosette casts. Ecosystem Monitoring Cruise Samples…
A new process-based model reproduces the Japanese beetle's invasion of northern Italy and Switzerland and projects invasion speeds of up to nearly 20 kilometers per year across Europe. Subject of Research: Spatial population dynamics modeling of the Japanese beetle invasion in…
Silencing the FECH gene in dwarf surf clams reduced heme, raised protoporphyrin IX, and turned their white shells brownish-yellow, supporting a proof-of-concept visible reporter system. Article Title: FECH negatively regulates protoporphyrin IX accumulation and shell coloration in the dwarf surf…
Two playful sea otters at the Oregon Zoo have taken their skills to the next level, slam-dunking miniature pumpkins through their hoop like basketballs. This inventive twist on their regular routine is not only a festive seasonal twist on their…
