Abstract In contrast to the classical notion of an increasing biodiversity from poles equator, a number studies concluded that diversity marine species is highest at middle latitudes, and decreases equator. Using worldwide database critically compiled 72 surveys (307 species, 4,807 water column surface sediment samples), we analyzed latitudinal gradients in richness ( LGSR ) highly diversified group holoplanktonic protists, polycystine Radiolaria. Species values were corrected for uneven...
The spread of nonindigenous species by shipping is a large and growing global problem that harms coastal ecosystems economies may blur biogeographical patterns. This study coupled eukaryotic environmental DNA (eDNA) metabarcoding with dissimilarity regression to test the hypothesis ship-borne homogenizes port communities. We first collected metabarcoded water samples from ports in Europe, Asia, Australia Americas. then calculated community dissimilarities between pairs tested for effects...
Summary Toxic cyanobacterial blooms and biological invasions are major threats to freshwater systems worldwide. While usually dealt with independently, the two can interact produce synergistic or antagonistic outcomes. The aim of this survey is analyse interactions between cyanobacterium M icrocystis spp. A sian invasive mussel L imnoperna fortunei . On basis 9 years observational data in a large subtropical reservoir ( S alto G rande, rgentina– U ruguay), we causal relationships recurring...
Corbicula jZuminea was collected at monthly intervals in November 1991-June 1993, and March, April 1995 a site located the vicinity of strong sources industrial sewage effluents (confluence Rivers San Antonio Vinculacibn, SaV); 1994 presumably less polluted one (Parana de las Palmas River, PP), lower delta Parana River (Argentina). Abundances SaV ranged between 430 10,300 ind. me2, being noticeably higher than those PP, as well 19 stations around these two locales. Shell lengths were...
In total, ca. 7000 zooplanktonic species have been described for the World Ocean. This figure represents less than 4% of total number known marine organisms. Of world-wide, some 60% are present in South Atlantic; about one third latter recorded its Subantarctic waters, and 20% south Polar Front. When compared with those benthic animals, these figures indicate that proportions overall inventories cold waters almost two times higher among zooplankton. agreement this pattern, Antarctic endemics...
