The fate of Arctic mosquitoes depends on habitat and access to blood meals

The future of Arctic mosquitoes (Aedes nigripes) in western Greenland depends on aquatic habitat and access to blood meals, according to a Dartmouth study. The study found that female mosquitoes carrying eggs were most abundant near ponds, especially in areas frequented by animals such as caribou, birds and the Arctic hare. Published in Ecosphere, the findings provide new insight into mosquito population dynamics. The rapid rate of environmental changes in the Arctic are impacting aquatic habitats and wildlife that mosquitoes depend on for blood meals. Mosquitoes also serve as food for a variety of species and pollinators for tundra plants in addition to their more notorious role as pests to humans and wildlife.

Three-dimensional model of human placenta developed

The placenta is the organ connecting mother and embryo. Its main functions are the exchange of nutrients, gases and metabolic products and the production of hormones and other substances essential for embryonic development. Placental malfunctions are the main cause of pregnancy complications and can lead to miscarriage and other serious disorders that endanger both mother and child. So far, the mechanisms underlying these disorders remain largely unexplained, not least because up until now there has been no reliable human cell culture model system. MedUni Vienna researchers have now successfully developed a 3-D model of the human placenta.

Biology news

Differences in immune responses create a genetic conflict between sexes

A unique study from Lund University in Sweden has discovered for the first time that there is a genetic sexual conflict in the immune system in animals. In females, the variation in central genes of the immune system is too high, whereas in males, it is too low. The researchers argue that the conflict is linked to differences in the immune responses of females and males.

Researchers discover a disease threatening the most plentiful starfish in Antarctica

A study led by experts from the University of Barcelona's Faculty of Biology and Institute for Research on Biodiversity (IRBio) have identified a disease that is affecting the starfish Odontaster validus, one of the most common species on the Antarctic sea floor. The disease, which is the first to be described in an echinoderm in Antarctica's marine environment, has afflicted up to 10 percent of the population of the species, the most important benthic predator in the coastal communities of Deception Island and other marine regions in Antarctic latitudes.

Wildflowers combat climate change with diversity

In 1859, when Charles Darwin first articulated the theory of evolution, he speculated that a process of natural selection led species to adapt to their environments over time. He believed traits that helped an organism survive were passed down to offspring, who would pass those traits on to more offspring, eventually leading to the diversity of life we see today.

How nutrients are removed in oxygen-depleted regions of the ocean

In the course of global climate change, scientists are observing the increase of low-oxygen areas in the ocean, also termed oxygen minimum zones (OMZs). Large-scale OMZs exist, for example, in the Pacific off the coast of South America or in the Indian Ocean. Since little to no oxygen is present in these regions—depending on the depth of the water—organisms whose metabolisms are independent of oxygen have a distinct advantage. These organisms include some representatives of the foraminifera: unicellular, shell-forming microorganisms, which have a nucleus and thus belong to the eukaryotes. Their lifestyle involves a particular metabolic pathway termed anaerobic respiration. In the absence of oxygen, they convert nitrate present in the water into molecular nitrogen.

A movie just recently released called "Rampage" features Dwayne "The Rock" Johnson using a genetic engineering technology called CRISPR, to transform a gorilla, among other animals, into a flying dragon-monster with gigantic teeth. Though this is science fiction, not to mention impossible, the movie captures the imagination of the public and their recent interest and fascination with CRISPR.

Pheromones in fight against pests

Nowadays, everybody is aware of the toxic effects of the conventional insecticides that are used to protect plants from pest insects. The insecticides are harmful to the farmer who sprays them on the field and for the pollinating insects, e.g., bees; and insecticide residues on fruits and vegetables are harmful to the consumer. But are there any safer ways to protect the plants from pest insects?

Tropical forest seeds use three strategies to survive

The oldest living seeds found on Earth germinated after resting more than 30,000 years in Arctic soils. But in the humid tropics, seeds do not last. "A long-lived seed in the tropics is probably only a few decades old. This may not seem like much time, but it is critical to reestablish trees after deforestation and ensure species' survival," said Camilo Zalamea, post-doctoral fellow and lead author of a new paper in Ecology from the Smithsonian Tropical Research Institute (STRI) in Panama.

How clean is your desk? The unwelcome reality of office hygeine

Abandoned farmlands enrich bird communities

Agriculture and conversion of pristine lands into urban or industrial areas have exerted immense pressure on natural biota due to habitat destruction and fragmentation in industrialized countries around the world. But since the 1900s, farmlands have been increasingly abandoned due to the decline in domestic agriculture and, in some countries, a decline in population. This yields an opportunity for abandoned farmlands to be used as rehabilitation zones for grassland, wetland, and forest animals. However, it has so far remained unclear how valuable for sustaining specific animal communities farmlands, abandoned farmlands, and natural habitats are relative to each other.

A new released Chinese soybean genome facilitates soybean elite cultivar improvement

Soybean (Glycine max [L.] Merr.) is one of the most important crops, providing more than half of global oilseed production and more than a quarter of the world's protein for food and animal feed. Studies have indicated that the cultivated soybean was domesticated in China approximately 5,000 years ago and then disseminated worldwide. During the introduction and dissemination process, soybean has undergone strictly genetic bottlenecks, resulting in the accessions from different geographic areas possibly exhibiting high genetic diversity. The current soybean reference genome was sequenced from Williams 82, which is a cultivar domesticated in America. Asia is one of the largest soybean planting and consuming areas, its soybean production is essential for global food security. A high-quality reference genome is crucial for functional analysis of a species. Therefore, it is necessary to assemble a new high-quality soybean genome from Asian soybean accessions to facilitate Asia soybean functional genomics study and elite cultivar improvement.
