Abstract The article analyses the waterspouts recorded in Balearic Islands (Spain) between 1989 and 2020. extensive database used includes 234 waterspout events, which we analysed to establish their annual, monthly, seasonal weekly spatial, temporal hourly distribution. autumn months account for 65% of all with highest frequency seen September. They occur most frequently 8:00 10:00 morning. We ...
Article history: Received 5 August 2015 Received in revised form 14 March 2016 Accepted 9 May 2016 Available online 10 May 2016 Dissolved organic carbon (DOC) concentrations in the deep Black Sea are ~2.5 times higher than found in the global ocean. The twomajor external sources of DOC are rivers and the Sea ofMarmara, a transit point forwaters from the Mediterranean Sea. In addition, expansive...
The sperm of Nucella are long and threadlike. The fiagellar shaft runs from the acrosome at the front of the head to the tip of the tail. Its anterior portion, the head shaft, is ensheathed by the nucleus. If a suspension of sperm in normal-concentration sea water is observed under phase contrast, and allowed to dry out slowly, the nuclear material of sperm near the edge of the coverglass swell...
Previous studies examining the seasonal contrast and spatial structure of the interdecadal variation in the Southern Hemisphere (SH) atmospheric circulation and the relationship between this interdecadal variation and cyclone activity have been extended using the SH data generated by the Australian Bureau of Meteorology for 1972–92. The major findings of this study are the following: 1) In addi...
A high-resolution multiproxy record, including pollen, foraminifera, and alkenone paleothermometry, obtained from a single core (DG9603) from the Okinawa Trough, East China Sea (ECS), provided unambiguous evidence for asynchronous climate change between the land and ocean over the past 40 ka. On land, the deglacial stage was characterized by rapid warming, as reflected by paleovegetation, and i...
Metagenomic sequencing increased our understanding of the role of the microbiome in health and disease, yet it only provides a snapshot of a highly dynamic ecosystem. Here, we show that the pattern of metagenomic sequencing read coverage for different microbial genomes contains a single trough and a single peak, the latter coinciding with the bacterial origin of replication. Furthermore, the ra...
The Ibis T5000 is a novel diagnostic platform that couples PCR and mass spectrometry. In this study, we developed an assay that can identify all known pathogenic Vibrio species and field-tested it using natural water samples from both freshwater lakes and the Georgian coastal zone of the Black Sea. Of the 278 total water samples screened, 9 different Vibrio species were detected, 114 (41%) samp...
Large scale land use/cover changes and habitat fragmentation have been associated with the decline of many wildlife populations in ecological sensitive regions. The main goal of this study was to quantify the spatial pattern changes in Caucasian Black Grouse habitat in Arasbaran Biosphere Reserve, Northwest of Iran in a period of 24 years (1987–2011). Caucasian black grouse (Tetrao mlokosiewicz...
