Aerobic anoxygenic photosynthesis in Sphingomonas glacialis strain S2U11 – how and why? Tekijä Palokas, Arla

“…The focus of this study was to explore the conditions that are required to induce or inhibit BChl a, and to a lesser degree, β-carotenes production in the bacterial species Sphingomonas glacialis strain S2U11. The possible relationship between BChl and carotenes production, and bacterial biomass production, was also assessed. …”

Thyroid Hormone Coordination of Thermogenesis and Thermoregulation in Winter Passerines Tekijä Crisp, Alma

“…These findings indicate population plasticity and flexibility in TH concentration in great tits. Although species differences were not found, due to size differences of the two species, similar TH concentration could be indicative of greater thermogenic needs in blue tits than great tits. …”

Where is rare? : global patterns of rarity in oceanic microbes Tekijä Summanen, Wilma

“… Microbes drive global biogeochemical cycles and ecosystem functions, thus providing essential ecosystem services. Yet, most microbial species are rare. While there is evidence that rare species make significant contributions to ecosystem functions, the distribution of rare microbial taxa remains uncharacterised, especially in terms of rare species’ functional traits. …”
