Potamophylax kosovaensis, a new insect species from Kosovo that is already endangered

The country’s natural wealth is under threat by manmade pressures such as water pollution, littering, and the construction of hydropower plants.

Over the last few years, professor Halil Ibrahimi from Kosovo and his team have described several new species of aquatic insects revered as bioindicators of freshwater ecosystems. However, the celebration of these discoveries is tempered by alarming concerns: the newfound species are often already considered endangered, as per the criteria set forth by the International Union for Conservation of Nature (IUCN), as soon as they are described. This classification underscores the urgent need for conservation efforts to safeguard their existence.

The research team just discovered a new species, named Potamophylax kosovaensis, in the spring area of the Llap River, nestled within the Ibër River Basin. The region, known for its ecological significance, serves as a critical habitat for numerous aquatic organisms like newly discovered insect species.

Unfortunately, these freshwater insects are facing unprecedented threats in Kosovo and the broader Balkans region. Anthropogenic pressures, such as water pollution, littering, and the construction of hydropower plants, pose imminent risks to their survival. The degradation of their habitats not only jeopardizes their existence, but also undermines the health and integrity of entire freshwater ecosystems.

Professor Ibrahimi emphasizes on the importance of urgent action to mitigate these threats and conserve this delicate balance of freshwater biodiversity. “The discovery of Potamophylax kosovaensis serves as a stark reminder of the fragility of our freshwater ecosystems,” he states. “We must prioritize efforts to protect these habitats and the invaluable species they harbor.”

The study was financed by the Integrated Water Resource Management in Kosovo (IWRM-K) and was conducted in the Laboratory of Zoology-Department of Biology of the University of Prishtina. It was published in the open-access, peer-reviewed Biodiversity Data Journal.

Citizen scientists discover a new snail and name it after Greta Thunberg

A new to science species of land snail was discovered by a group of citizen scientists working together with scientists from Taxon Expeditions, a company that organises scientific field trips for teams consisting of both scientists and laypeople. Having conducted a vote on how to name the species, the expedition participants and the local staff of the National Park together decided to name the mollusc Craspedotropis gretathunbergae. The species name honors the young Swedish activist Greta Thunberg for her efforts to raise awareness about climate change. The study is published in the open-access journal Biodiversity Data Journal.

“The newly described snail belongs to the so-called caenogastropods, a group of land snails known to be sensitive to drought, temperature extremes and forest degradation”,

says snail expert and co-founder of Taxon Expeditions, Dr. Menno Schilthuizen.

All individuals were found very close to the research field station (Kuala Belalong Field Studies Centre) at the foot of a steep hill-slope, next to a river bank, while foraging at night on the green leaves of understorey plants.

Citizen scientist J.P. Lim, who found the first specimen of Greta Thunberg’s snail says:

“Naming this snail after Greta Thunberg is our way of acknowledging that her generation will be responsible for fixing problems that they did not create. And it’s a promise that people from all generations will join her to help”.

The expedition team approached Ms. Thunberg who said that she would be “delighted” to have this species named after her.

However, this is not the first time that Taxon Expeditions team names a species in honour of an environmental advocate. In 2018, they named a new species of beetle after famous actor and climate activist Leonardo DiCaprio. Mr. DiCaprio temporarily changed his profile photo on Facebook to the photo of “his” beetle to acknowledge this honour.
