Fish moving poleward at rate of 26 kilometers per decade
Large numbers of fish will disappear from the tropics by 2050, finds a new University of Britsh Columbia study that examined the impact of climate change on fish stocks. The study identified ocean hotspots for local fish extinction but also found that changing temperatures will drive more fish into the Arctic and Antarctic waters. (2014-10-10)

Brazilian zoologists discovered the first obligate cave-dwelling flatworm in South America
Typical cave-dwelling organisms, unpigmented and eyeless, were discovered in a karst area located in northeastern Brazil. The organisms were assigned to a new genus and species of freshwater flatworm and may constitute an oceanic relict. They represent the first obligate cave-dwelling flatworm in South America. The genus and species names honor a Hungarian biologist who immigrated to Brazil and studied freshwater flatworms over many years. The study was published in the open access journal ZooKeys.

A new coral reef species from the Gambier Islands, French Polynesia
A new shallow water coral species, Echinophyllia tarae sp. n., is described from the Gambier Islands, French Polynesia. Scleractinia, also called stony corals, are exclusively marine animals; they are very similar to sea anemones but generate a hard skeleton. This coral was observed in muddy environments where several colonies showed partial mortality and re-growth. The paper describing to the new species was published in the open access journal ZooKeys.

Hidden diversity: 3 new species of land flatworms from the Brazilian Araucaria forest
A huge invertebrate diversity is hidden on the forest floor in the Araucaria moist forest. Land flatworms constitute a numerous group among these invertebrates occurring in the Neotropical region. Three new species of land flatworms were described from areas covered by the Araucaria moist forest in South Brazil. The new species were named after their characteristic color pattern. The study was published in the open-access journal ZooKeys. (2017-01-09)

Plastic waste is a hazard for subalpine lakes too
Many subalpine lakes may look beautiful and even pristine, but new evidence suggests they may also be contaminated with potentially hazardous plastics. Researchers say those tiny microplastics are likely finding their way into the food web through a wide range of freshwater invertebrates too. The findings, based on studies of Italy's Lake Garda and reported on October 7th in Current Biology, suggest that the problem of plastic pollution isn't limited to the ocean. (2013-10-07)

The genomic keys to the origin of the vertebrates
An international team of scientists led by Spanish researchers reports how more complex and specialized gene regulation proved to be pivotal in the origin of the vertebrates. The work, published recently by the Nature journal, compiles genomic, epigenomic and gene expression data from several organisms and provides unique information about the functional changes that gave rise to greater complexity in the vertebrates, particularly in the nervous system.

NE Australian marine heatwave shakes up coral reef animal populations
Research published today in Nature describes upheaval among fish and invertebrate communities after a marine heatwave hit Australia's Great Barrier Reef and Coral Sea in early 2016. The IMAS-led study analysed data collected across these areas by the Reef Life Survey (RLS) citizen science program. It identified important changes in reef-animal communities that may affect the resilience of coral reefs, potentially reducing the capacity of corals to rebuild after mass bleaching. (2018-07-25)

Snakes, salamanders and other creatures thrive in areas with higher deer populations
Reducing the number of deer in forests and parks may unexpectedly reduce the number of reptiles, amphibians and insects in that area, new research suggests. A recent study by researchers at Ohio State University and National Park Service found that higher deer activity is modifying forest ecosystems in unexpected ways. Out of several species of snakes, salamanders and invertebrates studied, a greater diversity of animals were found in areas with deer populations than were in areas with no deer activity.

Microplastics affect the survival of amphibians and invertebrates in river ecosystems
In collaboration with the National Museum of Natural Sciences (CSIC) in Madrid, the UPV/EHU's Stream Ecology research group has conducted two parallel studies to look at how the larvae of one freshwater amphibian and one invertebrate evolved during 15 days' exposure to microplastics at different concentrations. The highest concentrations used had lethal effects and the intermediate ones reduced the growth of the amphibians. (2020-03-10)

Uncovering secrets of life in the ocean
Scientists at the European Molecular Biology Laboratory and the Max Planck Institute for Developmental Biology now explain the remarkable ability of marine zooplankton to swim towards light. Their study, published in the current issue of Nature, reveals how simple eyes of only two cells, sense the direction of light and guide movement towards it. The research also provides new insights into what the first eyes in animal evolution might have looked like and what their function was. (2008-11-19)

Marine invertebrate larvae actively respond to their surroundings
Using larvae of sea urchins as test examples, scientists from HKUST and the Woods Hole Oceanographic Institution found that these little creatures actively modify their swimming speeds in response to ambient flow conditions. They actively increase their swimming speed in increased turbulence and are passively reoriented through morphology-flow interactions, which compromise their ability to maintain directed swimming. (2016-06-06)

Octopus genome reveals cephalopod secrets
Researchers from UC Berkeley, Okinawa Institute of Science and Technology Graduate University and University of Chicago sequenced and annotated the first cephalopod genome, the California two-spot octopus. They found widespread rearrangements of genes and a dramatic expansion of a family of genes involved in neuronal development that was once thought to be unique to vertebrates. Study of this and other cephalopod genomes will help reveal the genetic basis for these creatures' unusual behavior and physiology. (2015-08-12)

Biting backfire: Some mosquitoes actually benefit from pesticide application
The common perception that pesticides reduce or eliminate target insect species may not always hold. Jennifer Weathered and Edd Hammill report that the impacts of agricultural pesticides on assemblages of aquatic insects varied resulting in distinct ecological winners and losers within aquatic communities. (2019-06-17)

A lesson from Darwin
When British naturalist Charles Darwin traveled to the Galapagos Islands in 1835, he took notice of the giant kelp forests ringing the islands. He believed that if those forests were destroyed, a significant number of species would be lost. These underwater ecosystems, Darwin believed, could be even more important than forests on land.
