An investigation on the chloroplast and nuclear genomes of taxa belong to the subgenus Dracunculus (Bess.) Rydb. of Artemisia L. (Asteraceae) in Turkey

Braz. j. biol; 82 (), 2022
Artemisia is one of the biggest genera in the family Asteraceae, with around 500-600 taxa at specific and subspecific levels and organised in 5 subgenera. Due to the high number of taxa, a lot taxonomists are trying to solve the problem of its classification and phylogeny but its natural classification s...

Results permit a detailed assessment of primary homologies a...

Molecular classification and comparative phylogeographic study of insectivorous bat species (Pipisitrellus coromandra) from Punjab, Pakistan

Braz. j. biol; 82 (), 2022
Molecular based identification of bat fauna in Pakistan has been relatively less explored. The current study was therefore planned to report for the first time the molecular classification of insectivorous bats (Pipistrellus coromandra) based on mitochondrion gene (COI) from Punjab, Pakistan. Specimens w...

Review of the inquilinous fauna associated with insect galls in Brazilian restingas

Braz. j. biol; 82 (), 2022
Several records of associated fauna, including parasitoids, inquilines, predators, and successors, have been reported by insect gall inventories in Brazilian restingas. Although most guilds are well established, inquilines have frequently been misinterpreted. In this paper, the inquilinous fauna of insec...

Interações sexuais entre indivíduos do mesmo sexo: um olhar evolucionista

Psicol. USP; 33 (), 2022
Resumo Sob uma perspectiva evolutiva, as interações sexuais entre indivíduos do mesmo sexo foram por muito tempo consideradas um grande paradoxo.
