Homo sapiens or insapiens? A new insect species from Kosovo cries for help

Lying at the center of the Balkan Peninsula, Kosovo harbors a diversity of ecosystems and conditions, which have favored processes leading to the existence of many endemic and rare species. In the past few years, several new species of aquatic insects have been discovered from the small Balkan country, making it unique in terms of biodiversity. Unfortunately, as elsewhere in the Balkans, many of these ecosystems have deteriorated heavily.

A team of scientists from Kosovo, led by Professor Halil Ibrahimi of the University of Prishtina, recently found a new species of aquatic insect, a caddisfly, from the Sharr Mountains in Kosovo, and named it Potamophylax humoinsapiens.

The species epithet humoinsapiens is a combination of two Latin words, “humo”, which in English means “to cover with soil, to bury,” and “insapiens,” meaning “unwise”. The researchers explain this name refers to the unwise and careless treatment of the habitats of the new species: hydropower plant, illegal logging and pollution have greatly degraded the area in the past years. “In some segments, whole parts of the Lepenc River are “buried” in large pipes,” they write in their study, which was published in the open-access Biodiversity Data Journal.

“The species name ‘humoinsapiens’ ironically sounds like Homo insapiens, and this new species is right in calling us unwise,” thinks Prof. Ibrahimi. “With its actions, humankind has caused the extinction of many species of insects and other organisms during the past decades and has degraded greatly all known ecosystems in the planet. The debate on questioning wise nature of humans is already ongoing.

In the past few years, Professor Halil Ibrahimi and his team have found several new species of aquatic insects from the Balkans, Middle East and North Africa. In an attempt to raise awareness for this group of vulnerable creatures, endangered greatly by human activities, the team of scientists has given their species unique names. One of their previous discoveries was named Potamophylax coronavirus in order to raise the attention to the silent and dangerous “pandemic” humans have caused in freshwater ecosystems in the Balkans.

“By combining classical taxonomy and modern molecular analysis techniques with the unique names, we are making insect species talk to our collective consciousness. It is in humankind’s capacity to earn the name Homo sapiens again,” the researchers conclude.

The study was financed by the Ministry of Education, Science, Technology and Information of the Republic of Kosovo and was conducted in the Laboratory of Zoology-Department of Biology of the University of Prishtina.

Bee diversity and richness decline as anthropogenic activity increases, confirm scientists

The researchers compared wild bee communities in the tropical dry forest of Mexico living in three habitat conditions: preserved vegetation, agricultural sites and urbanised areas

Changes in land use negatively affect bee species richness and diversity, and cause major shifts in species composition, reports a recent study of native wild bees, conducted at the Sierra de Quila Flora and Fauna Protection Area and its influence zone in Mexico.

Having registered a total of 14,054 individual bees representing 160 species, 52 genera, and five families over the span of a year, the scientists conclude that the studied preserved areas demonstrated “significantly greater” richness and diversity.

In their paper, published in the open-access Journal of Hymenoptera Research, a research team from the University of Guadalajara, Mexico, led by Alejandro Muñoz-Urias, compare three conditions within the tropical dry forest study site: preserved vegetation, an agricultural area with crops and livestock, and an urbanised area.

This bee species (Aztecanthidium xochipillium) is known exclusively from Mexico.

The researchers confirm earlier information that an increase in anthropogenic disturbances leads to a decrease in bee richness and diversity. While availability of food and nesting sites are the key factors for bee communities, changes in land use negatively impact flower richness and floral diversity. Thereby, turning habitats into urbanised or agricultural sites significantly diminishes the populations of the bees which rely on specific plants for nectar and pollen. These are the species whose populations are threatened with severe declines up to the point of local extinction.

According to their data, about half of the bees recorded were Western honey bees (49.9%), whereas polyester bees turned out to be the least abundant (1.2 %).

On the other hand, some generalist bees, which feed on a wide range of plants, seem to thrive in urbanised areas, as they take advantage of people watering wild and ornamental plants at times where draughts might be eradicating native vegetation.

“That is the reason why bees that can use a wide variety of resources are often able to compensate when circumstances change, although some species disappear due to land use changes,” explain the scientists.

This is a tropical dry forest in the dry (left) and rainy season (right).

In conclusion, the authors recommend that the tropical dry forests of both the study area and Mexico in general need to be protected in order for these essential pollinators to be conserved.

“Pollinators are a key component for global biodiversity, because they assist in the sexual reproduction of many plant species and play a crucial role in maintaining terrestrial ecosystems and food security for human beings,” they remind.
