Calcium sensitivity of myosin cross-bridge activation in striated muscles commonly varies during ontogeny and in response to alterations in muscle usage, but the consequences for whole-organism physiology are not well known. Here we show that the relative abundances of alternatively spliced transcripts of the calcium regulatory protein troponin T (TnT) vary widely in flight muscle of Libellula ...

The endosymbiotic relationship between coral hosts and dinoflagellates of the genus Symbiodinium is critical for the growth and productivity of coral reef ecosystems. Here, synchrotron radiation-based infrared microspectroscopy was applied to examine metabolite concentration differences between endosymbiotic (within the anemone Aiptasia pulchella) and free-living Symbiodinium over the light-dar...

Dermatophytes, related keratinophilic and opportunistic fungi were isolated from indoor dust samples of 46 hospitals and 47 houses in Kanpur. A total of 19 fungi represented by 11 genera were isolated by the hair-baiting technique from 230 and 235 samples from hospitals and houses respectively. The isolated fungi are Acremonium implicatum (Indian Type Culture Collection) ITCC 5266, A. strictum ...

. Abstract: Polychaete species composition, abundance and seasonal variation were analyzed in relation to Spartina alterniflora cover and tide levei at Ponta do Arrozal, Cananéia, during 1989/1990. Two intertidal stations were located on the S. alterniflora OOlt,one ca mean high water of neap tides (MHWN) and the other ca mean high water of spring tides (MHWS). Two other stations were establish...

Unoccupied Aircraft Systems (UAS) are beginning to replace conventional forest plot mensuration through their use as low-cost and powerful remote sensing tools for monitoring growth, estimating biomass, evaluating carbon stocks detecting weeds; however, physical samples remain mostly collected time-consuming, expensive potentially dangerous techniques. Such techniques include the of arborists c...

The grape hyacinth (Muscari) represents an important ornamental plant group in Asparagaceae subfamily Scilloideae, comprising some 80 species distributed mainly the Mediterranean. However, genus delimitation has repeatedly shifted over past two centuries and a general consensus not been reached so far. present study investigates phylogeny of Muscari s.l. (i.e., including disputed segregates Pse...
