Punjabi University researchers study dragonflies of the Libellulidae family

Say these colourful insects are large for knowing ecology that however surviving things interact with their environment

Researchers astatine Punjabi University, Patiala, studied dragonflies from the Libellulidae family, which are colourful insects often seen adjacent lakes and ponds.

The probe enactment carried retired by Hardeep Singh and supervised by Prof Gurinder Kaur Walia, astatine the Department of Zoology and Environmental Science, looked astatine the dragonflies’ chromosomes (structures that transportation familial information) and their DNA to recognize however antithetic taxon are related to each other.

Hardeep Singh said that they collected dragonflies from assorted parts of North and South India and examined the chromosomes of these dragonflies to place unsocial features and cheque for immoderate changes successful their structure. He said that they besides studied a circumstantial cistron (mitochondrial COI gene) successful the dragonflies’ DNA, which acts similar a 'barcode' to archer taxon isolated and amusement however they’re related. By combining the chromosome and DNA data, they confirmed however these dragonfly taxon evolved and are connected.

He further stated that the findings were published successful 4 probe papers successful well-known planetary journals.

Prof Walia said that the survey added 5 caller dragonfly taxon to the planetary database of 258 taxon studied for their chromosomes. They submitted DNA information for 28 sequences from 21 taxon to a planetary database (NCBI) and analysed 112 DNA sequences from 80 taxon to representation retired however these dragonflies are related evolutionarily. She said that dragonflies are past insects, astir for astir 220 cardinal years, and are related to immoderate of the earliest winged insects. They are important for studying freshwater environments (like lakes and rivers) due to the fact that antithetic taxon request antithetic habitats and they person analyzable beingness cycles (partly successful water, partially connected land). This makes them large for knowing ecology that however surviving things interact with their situation and astir evolution.

Vice-Chancellor Dr Jagdeep Singh, portion appreciating the research, congratulated the researcher and the supervisor. He said that specified researches are a testament to the prime of probe being done successful the assemblage which enhances the prestige of the institution.
