Especially male poison frogs piggyback their offspring to pools in the rainforest. Now, researchers from Vetmeduni Vienna, the University of Vienna and Harvard University showed that this parental behavior can be triggered experimentally. With unrelated tadpoles placed on their backs, male -- and even female -- 'foster parents' behave as if they had picked up the tadpoles themselves. This showed for the first time that an external stimulus triggers complex behaviors in amphibians. Journal of Experimental Biology.
new study of the world's seven sea turtle species provides evidence that their numbers are growing overall (unlike many endangered vertebrates), thanks to years of conservation efforts that have played a key role in sea turtle recovery -- even for small sea turtle populations.
A new Biological Reviews study provides a comprehensive assessment of how changes to wetlands affect animals, and the authors use their findings to provide recommendations for managing wetlands to maximise their biodiversity.
New research indicates that fish may adapt their behavior to defend against parasite infection. The findings are published in the Journal of Zoology.
A new hermit crab species can live in a walking coral's cavity in a reciprocal relationship, replacing the usual marine worm partner, according to a study published Sept. 20, 2017, in the open-access journal PLOS ONE by Momoko Igawa and Makoto Kato from Kyoto University, Japan.
A deadly amphibian disease called severe Perkinsea infections, or SPI, is the cause of many large-scale frog die-offs in the United States, according to a new study by the US Geological Survey.
NOAA Fisheries researchers and colleagues at the New England Aquarium have developed a new model to improve estimates of abundance and population trends of endangered North Atlantic right whales, which have declined in numbers and productivity in recent years. Between 1990 and 2010 abundance increased to 482 animals, but since 2010 the numbers have declined to 458 in 2015, with 14 known deaths this year. The findings were published in the journal Ecology and Evolution.
Sushi is sublime. Just fresh fish and seasoned rice in its simplest form served one on top of the other, or rolled up with some veggies in a seaweed wrapper. But creates the subtle interplay of flavors in your tuna nigiri? Take a deep dive into the chemistry of rice, fish and seaweed in this video from Reactions: https://youtu.be/6F_OWtoTTrA
To provide a vital scientific foundation for conservation efforts, an international team has conducted a genetic analysis comparing queen conch at 19 sites throughout the Caribbean. Their findings, published Sept. 19 in the journal Diversity and Distributions, will help scientists understand how local subpopulations of conch are fragmented throughout the Caribbean, an essential first step needed to develop effective science-driven management plans and practices.
The Indonesian coral reefs, located in the so-called coral triangle, are considered amongst the richest and most biodiverse places on Earth. Surprisingly, this impressive species diversity is still poorly known. The paper, authored by an international team led by Barbara Calcinai and published in the open access journal ZooKeys, reports the presence of 94 species of sponges, including six new to science and two new symbiotic sponge associations.
