Orchids have evolved flowers with unique morphologies through coevolution with pollinators, such as insects.Among the floral organs, the lip (labellum), one of the three petals, exhibits a distinctive shape and plays a crucial role in attracting pollinators and facilitating pollination in many orchids.The lip of the terrestrial orchid Habenaria rad
Positive selection over the mitochondrial genome and its role in the diversification of gentoo penguins in response to adaptation in isolation
Abstract Although mitochondrial DNA has been widely used in phylogeography, evidence has emerged that factors such as climate, food availability, and environmental pressures that produce high levels of stress can exert a strong influence on mitochondrial genomes, to the point of promoting the persistence of certain genotypes in order to compensate
Technologies for reducing emissions and costs in combined heat and power production
According Finnish Energy association, in Finland roughly three-quarters of district heat production is based on combined heat and power (CHP) generation.Correspondingly, one-third of electricity is generated using CHP.In Finland, the market share of CHP derived electricity is significant, and therefore used technologies and fuels should be carefull
