For the first time, scientists report a vampire fish attached to the body of an Amazonian thorny catfish. Very unusually, the candirus were attached close to the lateral bone plates, rather than the gills, where they are normally found. Since the hosts were not badly harmed, and the candirus apparently derived no food benefit, scientists believe this association is commensalistic rather than parasitic. The research is published in the open-access journal Acta Ichthyologica et Piscatoria.
Have you ever seen a one-centimetre-long jumping critter in a leaflitter or close to a pond or a stream and thought that it is some juvenile insect? What you saw was probably an adult pygmy grasshopper, member of the family Tetrigidae. There are more than 2000 described species of those minute jumping insects, and this peculiar family has been around for more than 230 million years, meaninng that pygmies said both ‘hi’ and ‘bye’ to dinosaurs. And yet, we know more about dinosaurs than we do about pygmy grasshoppers.
guest blog post by Matteo Vecchi One of the main threats to biodiversity conservation is not recognizing the uniqueness of species – without a formal name, a species cannot be protected properly. Tardigrades – microorganisms also known as water bears or moss piglets – are no exception. When we were faced with two new species, […]
Guest blog post by Kennedy “Ned” Rubert-Nason, Caitlin Mandeville and Kirsten Schwarz Global change is an immediate, accelerating threat to humanity, and its impacts are perpetuated by human activities. Changes such as climate warming, landscape alteration, pollution, resource extraction and depletion, extreme events, biodiversity loss, and spreading of invasive species including diseases, threaten the natural […]
Guest blog post by Dr Emilio Cervantes Grape seeds have a characteristic oval or pear-like shape. It has been long recognised that this form is variable, and that, in general, wild-type seeds are smaller and more rounded, while the seeds of cultivated varieties tend to be more elongated in one side, or pear-shaped. Recently, seeds […]
A Brazilian network of female zoologists aims to oppose gender disparity in science Guest blog post by Veronica Slobodian Scientists are part of a rather sexist society and, therefore, ruled by a rather sexist social conduct. Nevertheless, women scientists attempt to thrive despite all setbacks provided by structural sexism (both explicit and implicit). Sadly, female […]
By 2020, losses of corals have been observed throughout Florida and into the greater Caribbean basin in what turned out to be likely the most lethal recorded case of Stony Coral Tissue Loss Disease. A Perspectives paper, published in the open-access peer-reviewed journal Rethinking Ecology, provides an overview of how Florida ended up in a situation, where the best that could be done is rescuing genetic material from coral species at risk of regional extinction.
Guest blog post by Dr Robert Mesibov Proofreading the text of scientific papers isn’t hard, although it can be tedious. Are all the words spelled correctly? Is all the punctuation correct and in the right place? Is the writing clear and concise, with correct grammar? Are all the cited references listed in the References section, […]
Guest blog post by Marcos Caraballo The birdcatcher trees – genus Pisonia – are infamous for trapping birds with their super-sticky seed pods that would frequently entangle the body of the ‘victim’. Left flightless, the poor feathered creatures eventually die either from starvation or fatigue, or predators. Similarly notorious are the birdcatcher trees for botanists, […]
