Scientists discovered 20 new gnat species in Brazil

24.09.2018

Due to the heterogenity of natural habitats and its dimension, Brazil is thought to hold 15 - 20% of the biodiversity on planet Earth. A study conducted in the Brazilian Atlantic Forest under the leadership of senior researcher Olavi Kurina from the Chair of Biodiversity and Nature Tourism at Estonian University of Life Sciences could only confirm this theory.

The Atlantic Forest ecoregion in Brazil is an area with diverse nature, following the coastline of the country and embracing tropical, subtropical and mangrove forests, also shrubland and grassland, described Olavi Kurina. "There are many endemic species known in this region."

In addition to the known biodiversity, in September the researches described in these rainforests 20 gnat species in the genus Manota that were new to science.

The described species belong to the family of fungus gnats (Mycetophilidae) and are small flies, from 1.5 to 3mm long, with specific differences lying mainly in terminal morphology of the male specimens, specified Olavi Kurina.

The new species received scientific names by their morphological features and in honour of colleagues who had contributed to the research. As a result of zoogeographic analysis, a discrepancy was described between the comparatively wide distribution of the Manota species and the areas of endemism known for Diptera in South America and in Brazilian Atlantic Forest particularly.

###

The study, the first in-depth treatment of the genus Manota in Brazil, was carried out in cooperation with Estonian University of Life Sciences, University of Turku and University of São Paulo.

The type material of the new species is deposited in the insect collections of Estonian University of Life Sciences and University of São Paulo (international acronyms IZBE and MZUSP, respectively).

The scientific journal Zootaxa, a mega journal for zoological taxonomists in the world, published an article on this topic: http://www.mapress.com/j/zt/article/view/zootaxa.4472.1.1.

Im Focus: Goodbye, silicon? On the way to new electronic materials with metal-organic networks

Scientists at the Max Planck Institute for Polymer Research (MPI-P) in Mainz (Germany) together with scientists from Dresden, Leipzig, Sofia (Bulgaria) and Madrid (Spain) have now developed and characterized a novel, metal-organic material which displays electrical properties mimicking those of highly crystalline silicon. The material which can easily be fabricated at room temperature could serve as a replacement for expensive conventional inorganic materials used in optoelectronics.

Silicon, a so called semiconductor, is currently widely employed for the development of components such as solar cells, LEDs or computer chips. High purity...

Augsburg chemists present a new technology for compressing, storing and transporting highly volatile gases in porous frameworks/New prospects for gas-powered vehicles

Storage of highly volatile gases has always been a major technological challenge, not least for use in the automotive sector, for, for example, methane or...

Im Focus: Disrupting crystalline order to restore superfluidity

When we put water in a freezer, water molecules crystallize and form ice. This change from one phase of matter to another is called a phase transition. While this transition, and countless others that occur in nature, typically takes place at the same fixed conditions, such as the freezing point, one can ask how it can be influenced in a controlled way.

We are all familiar with such control of the freezing transition, as it is an essential ingredient in the art of making a sorbet or a slushy. To make a cold...
