Pacific cod can't rely on coastal safe havens for protection during marine heat waves      (via sciencedaily.com)     Original source 

During recent periods of unusually warm water in the Gulf of Alaska, young Pacific cod in near shore safe havens where they typically spend their adolescence did not experience the protective effects those areas typically provide, a new study found.

Invasive ants spread by hitchhiking on everyday vehicles      (via sciencedaily.com)     Original source 

Ants might spread to new locations by stowing away on everyday vehicles. Previously, this was thought to occur mostly on agricultural equipment.

Researchers find genetic stability in a long-term Panamanian hybrid zone of manakin birds      (via sciencedaily.com)     Original source 

We often think of species as separate and distinct, but sometimes they can interbreed and create hybrids. When this happens consistently in a specific area, it forms what's known as a hybrid zone. These zones can be highly dynamic or remarkably stable, and studying them can reveal key insights into how species boundaries evolve -- or sometimes blur. Researchers now describe a hybrid zone between two manakin species in Panama that has overall remained relatively stable over the past 30 years.

Brain's 'escape switch' controlled by threat sensitivity dial      (via sciencedaily.com)     Original source 

Neuroscientists have discovered how the brain bidirectionally controls sensitivity to threats to initiate and complete escape behaviour in mice. These findings could help unlock new directions for discovering therapies for anxiety and post-traumatic stress disorder (PTSD).

New tomato, potato family tree shows that fruit color and size evolved together      (via sciencedaily.com)     Original source 

A new family tree of the plant genus Solanum helps explain the striking diversity of their fruit color and size. This genus includes tomatoes, potatoes, eggplants, and other economically important plants.

Unifying behavioral analysis through animal foundation models      (via sciencedaily.com)     Original source 

Behavioral analysis can provide a lot of information about the health status or motivations of a living being. A new technology makes it possible for a single deep learning model to detect animal motion across many species and environments. This 'foundational model', called SuperAnimal, can be used for animal conservation, biomedicine, and neuroscience research.

Insecticides contributed to loss of butterflies across American Midwest, study finds      (via sciencedaily.com)     Original source 

Insecticide use is a major factor causing a decrease in the size and diversity of butterfly populations across the US Midwest, according to a new study.

Interaction with insects accelerates plant evolution      (via sciencedaily.com)     Original source 

Researchers have discovered that plants benefit from a greater variety of interactions with pollinators and herbivores. Plants that are pollinated by insects and have to defend themselves against herbivores have evolved to be better adapted to different types of soil.

Odors are encoded in rings in the brain of migratory locusts      (via sciencedaily.com)     Original source 

Researchers describe how odors are encoded in the antennal lobe, the olfactory center in the brain of migratory locusts. Using transgenic locusts and imaging techniques, the researchers were able to show a ring-shaped representation of odors in the brain. The pattern of olfactory coding in the antennal lobe is the same at all stages of locust development. A better understanding of olfactory coding in the locust brain should help to learn more about how the behavior of these insects is controlled, especially their swarming.

Fishy parenting? Punishing offspring encourages cooperation      (via sciencedaily.com)     Original source 

Scientists discovered that Neolamprologus savoryi fish use punishment to encourage offspring to cooperate in brood care, revealing advanced cognitive abilities previously thought unique to higher vertebrates. This study highlights that punishment for promoting cooperation exists beyond human societies, prompting a reevaluation of animal intelligence.

Restored rat-free islands could support hundreds of thousands more breeding seabirds      (via sciencedaily.com)     Original source 

Archipelago case-study shows that removing invasive rats and restoring native vegetation could help bring back hundreds of thousands of breeding pairs of seabirds lost to tropical islands. Calculating that there are enough fish to sustain restored seabird populations should be an important consideration for restoration projects, scientists say. Restored seabird populations also provide huge boost to the health of surrounding coral reef ecosystems through restored nutrient cycles.

Nile perch invasion triggered genetic bottlenecks in Lake Victoria's endemic cichlids      (via sciencedaily.com)     Original source 

Newfound evidence reveals that the upsurge of the exotic Nile perch in Lake Victoria had long-lasting effects on the genetic diversity of various local cichlid species, report scientists. Through large-scale comparative genomic analyses, the researchers found concrete proof in the collective genome of multiple species that this artificially introduced perch decimated many local fish populations, causing a 'bottleneck effect.'

Previously uncharacterized parasite uncovered in fish worldwide      (via sciencedaily.com)     Original source 

Using genome reconstruction, scientists unveiled a once 'invisible' fish parasite present in many marine fish world-wide that belongs to the apicomplexans, one of the most important groups of parasites at a clinical level. However, it had gone unnoticed in previous studies. The parasite is geographically and taxonomically widespread in fish species around the planet, with implications for commercial fishing and oceanic food webs.

Ancient polar sea reptile fossil is oldest ever found in Southern Hemisphere      (via sciencedaily.com)     Original source 

An international team of scientists has identified the oldest fossil of a sea-going reptile from the Southern Hemisphere -- a nothosaur vertebra found on New Zealand's South Island. 246 million years ago, at the beginning of the Age of Dinosaurs, New Zealand was located on the southern polar coast of a vast super-ocean called Panthalassa. 'The nothosaur found in New Zealand is over 40 million years older than the previously oldest known sauropterygian fossils from the Southern Hemisphere.

Is magnesium the sleeping potion that enables sandhoppers to survive cold winters?      (via sciencedaily.com)     Original source 

A new study has shown for the first time that when sandhoppers want to enter a period of deep sleep each winter they have the means through which to increase the magnesium levels in their bodies -- in some instances more than doubling them. Essentially acting as a natural narcotic, the magnesium puts the sandhopper into a torpid state and this enforced rest means that the creatures can stay hidden in burrows up to 30cm beneath the beach surface, to some extent buffered from wintry conditions.
