This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Two mosquito species in America have been engaged in a battle for dominance for the past 30 years: the native Aedes aegypti and the invasive Aedes albopictus -- also known as the Asian tiger mosquito The tiger mosquito has a distinct competitive advantage Male Aedes albopictus are really good at wooing female Aedes aegypti The resultant interspecies mating permanently sterilizes the female, effectively ending her reproductive future But Aedes aegypti are evolving the ability to resist the advances of Aedes albopictus Although this is good news for Aedes aegypti the outlook is darker for humans, as Aedes aegypti are key transmitters of diseases like Zika and dengue fever Researchers have now started to uncover the genetic changes tied to this resistance Uncovering the molecular correlates governing mosquito mating preferences could lead to better control strategies and might help prevent future outbreaks of disease Burford Reiskind, et al..."

How genetics can add to our understanding of cognition, language, emotion, personality, and behavior. Use of gene mapping to estimate risk factors for psychological disorders and variation in behavioral and personality traits. Mendelian genetics, genetic mapping techniques, and statistical analysis of large populations and their application to particular studies in behavioral genetics. Topics also include environmental influence on genetic programs, evolutionary genetics, and the larger scientific, social, ethical, and philosophical implications.

Genetically engineered wheat releases insect pheromones to ward off pests

"The aphid -- one of the most common crop pests in the world -- has a weakness that scientists have now learned to exploit. When attacked by predators, the bugs release a pheromone to tell fellow insects to scatter. Biologists have proposed spraying these alarm pheromones directly on crops to prevent pest damage, but synthesis is costly. With the advent of genetic engineering, though, the cheaper option is to modify crops to produce the deterrents themselves. In 2015, biologists at Rothamsted Research, an agricultural research station in the UK, reported the first engineering feat of this kind in wheat. To make wheat release insect pheromones, the group inserted a gene from the peppermint plant, which allows plants to produce the appropriate chemical. Then, they tested whether the altered plants’ volatile compounds were capable of repelling the pests..."

Public Data Archiving in Ecology and Evolution: How Well Are We Doing?
Unrestricted Use
CC BY
Rating
0.0 stars

Policies that mandate public data archiving (PDA) successfully increase accessibility to data underlying scientific publications. However, is the data quality sufficient to allow reuse and reanalysis? We surveyed 100 datasets associated with nonmolecular studies in journals that commonly publish ecological and evolutionary research and have a strong PDA policy. Out of these datasets, 56% were incomplete, and 64% were archived in a way that partially or entirely prevented reuse. We suggest that cultural shifts facilitating clearer benefits to authors are necessary to achieve high-quality PDA and highlight key guidelines to help authors increase their data’s reuse potential and compliance with journal data policies.

"Understanding the genetic basis of physical traits has long been of interest to biologists. But uncovering the precise DNA changes that underlie changes in morphology is a difficult task. Now, a team of researchers has done just that in stickleback fish, shedding light on the evolution of morphological diversity found in naturally occurring species. Three-spine sticklebacks in marine environments typically have long dorsal spines that form part of their skeletal armor. Populations found in freshwater, however, often have much shorter spines or, in some cases, have lost these spines all-together. So what is the cause of this drastic morphological difference? To find out, a team of researchers in the US carried out a number of crosses and an in-depth genetic study of both freshwater and marine populations..."

The video's transcript is also provided in full, with a portion provided below for preview:

"EnvironmentalDNA capture is helping researchers do the seemingly impossible: track the numerous plants and animals that call natural waters home. But fishing for so-called eDNA can be precarious work. Each step of the process, from water sampling to DNA detection, is a point of entry for contaminants or of loss for sample material. Now, a new standard could be in the making. Self-preserving and partially biodegradable, this new filtration system eliminates data-compromising steps from eDNA capture while ensuring long-term sample preservation and generating less plastic waste. In standard eDNA collection, a motorized or hand-powered pump is used to force a water sample through a DNA-capturing membrane. The filter housing is then opened and, using sterilized forceps, the membrane is carefully transferred to a vial. Finally, ethanol is added to preserve the captured eDNA while its transported to a lab for sequencing or PCR detection..."
