Therefore, the animal is having prime importance in basic biological, aging, and biomedical researches. However, till date, the genome of this organism has not been sequenced and even there is no molecular phylogenetic study to reveal its close relatives. Here, using phylogenetic analysis based on available 16s rRNA gene and protein sequences of Cytochrome oxidase subunit-I (COI or COX1) of T. nutricula, we have predicted the closest relatives of the organism. While we found Nemopsis bachei could be closest organism based on COX1 gene sequence; T. dohrnii may be designated as the closest taxon to T.

  • Tropical Fish Now That You Have Set up Your Aquarium and Are Starting to Think About Adding Fish, You Have Many Choices to Choose From
    Tropical Fish Now that you have set up your aquarium and are starting to think about adding fish, you have many choices to choose from. One specific type of fish is the tropical fish, found in tropical waters all over the world and in areas near the equator. They can live in fresh water such as ponds, lakes, streams and even oceans that are salt water. In home aquariums, tropical fish are usually kept in heated fish tanks or in areas where the ambient room temperature is between 70°F - 82°F. As you make your decisions, be sure to research their compatibility, hardiness and if they are a schooling fish or not. Selecting the right fish will help ensure that you have hours of enjoyment and success. Today, many freshwater fish are captive bred either in fish farms or by hobbyists, making them readily available and easy to find. Popular freshwater tropical fish include Bettas, Guppies, Tetras, Swordtails, Platys, Barbs, Mollies and Corydoras among others. Sometimes people starting out in the aquatic hobby may not always provide their fish with ideal living conditions. Fish recommended for beginners and new aquariums must be durable and able to handle sometimes-poor water quality and stressful living conditions. The list included here are freshwater fish and will provide you with a nice assortment to consider. Cold -Water Fish The most common cold-water fish species is the goldfish but there are many other fish species that do not require a heated tank such as White Cloud Mountain Minnows, Bloodfin Tetras, and Rosy Barbs among others; where their preferred water temperature is between 64 to 72 degrees F.

Lodge1,2 1Department of Biological Sciences, University of Notre Dame, Notre Dame, IN 46556 USA 2Environmental National Center for Ecological Analysis and Synthesis, 735 State Street, Suite 300, Santa Barbara, CA 93101 USA *Corresponding author Current address: Institute of Ecology, University of Georgia, Athens, GA 30602 USA E-mail: [email protected] (JMD) Received: 13 March 2007 / Accepted: 25 May 2007 Abstract Anthropogenic biological invasions are a leading threat to aquatic biodiversity in marine, estuarine, and freshwater ecosystems worldwide. Ballast water discharged from transoceanic ships is commonly believed to be the dominant pathway for species introduction and is therefore increasingly subject to domestic and international regulation. However, compared to species introductions from ballast, translocation by biofouling of ships’ exposed surfaces has been poorly quantified. We report translocation of species by a transoceanic bulk carrier intercepted in the North American Great Lakes in fall 2001. We collected 944 individuals of at least 74 distinct freshwater and marine taxa. Eight of 29 taxa identified to species have never been observed in the Great Lakes. Employing five different statistical techniques, we estimated that the biofouling community of this ship comprised from 100 to 200 species. These findings adjust upward by an order of magnitude the number of species collected from a single ship.

The seasonal abundance and distribution of the dominant species of hydromedusae along a salinity gradient within the Gironde Estuary, Atlantic coast of France, were evaluated based on monthly surveys, June 2013 to April 2014. The results confirmed the presence of three species considered to be introduced in many coastal ecosystems around the world: Nemopsis bachei (Agassiz, 1849), Blackfordia virginica (Mayer, 1910), and Maeotias marginata (Modeer, 1791). These species were found at salinities ranging from 0 to 22.9 and temperatures ranging from 14.5 to 26.6 ºC, demonstrating their tolerance to a wide range of estuarine environmental conditions.

The thecostracan barnacles rank among the most commonly encountered marine crustaceans in the world. They deviate from almost all other Crustacea in that only the larvae are free-living, while the adults are permanently sessile and morphologically highly specialized as filter feeders or parasites. In the most recent classifications of the crustacean Maxillopoda 1 and latest phylogenetic analyses 2-4 the Thecostraca sensu Grygier 5, comprising the Facetotecta, Ascothoracida, and Cirripedia, form monophyletic assemblages. Barnacle phylogenetics has advanced greatly over the last 10 years. Nonetheless, the relationships and taxonomic status of some groups within these three infraclasses are still a matter of debate. While the barnacles where the focus of Darwin’s detailed taxonomic work, there has not been a comprehensive review of the species of barnacles as a whole since Darwin. As a consequence, the barnacle entries within the WoRMS Database is woefully out of date taxonomically and missing many, many species and higher taxa.

Mehedi Alam b, Mohammad Mahfujul Haque b,* a Department of Fisheries, University of Rajshahi, Rajshahi, Bangladesh b Department of Aquaculture, Bangladesh Agricultural University, Mymensingh, Bangladesh ARTICLE INFO ABSTRACT Keywords: This study evaluates changes in fish species diversity over time in Hakaluki Haor, an ecologically critical wetland Haor in Bangladesh, and the factors affecting this diversity. Fish species diversity data were collected from fishers using Fish species diversity participatory rural appraisal tools and the change in the fish species diversity was determined using Shannon- Fishers Wiener, Margalef's Richness and Pielou's Evenness indices. Principal component analysis (PCA) was conducted Principal component analysis with a dataset of 150 fishers survey to characterize the major factors responsible for the reduction of fish species Climate change fi Anthropogenic activity diversity. Out of 63 sh species, 83% of them were under the available category in 2008 which decreased to 51% in 2018. Fish species diversity indices for all 12 taxonomic orders in 2008 declined remarkably in 2018. The first PCA (climatic change) responsible for the reduced fish species diversity explained 24.05% of the variance and consisted of erratic rainfall (positive correlation coefficient 0.680), heavy rainfall (À0.544), temperature fluctu- ation (0.561), and beel siltation (0.503). The second PCA was anthropogenic activity, including the use of harmful fishing gear (0.702), application of urea to harvest fish (0.673), drying beels annually (0.531), and overfishing (0.513).

Smithsonian Contributions to Botany, number 34, 22 pages, 13 figures, 1976.-Six species of benthic marine algae (one Chlorophyta, two Phaeophyta, and three Rhodophyta) are newly reported from the Gulf of California, hfexico. Species of Halicystis, Sporochnus, Bonnemaisonia, Dudresnnya, and Sebdenia represent genera new to the Gulf, with the last being new to North America. The distribu~ionof twelve other species is extended. Two new nomenclatural combinations, Dasya bailloziviana var. nudicaulus and Dasya baillouviana var, stanfordiana, are proposed. The morphological variation of some species is discussed. Spermatangia of Dudresnnya colombiana, and tetrasporangia and spermatangia of Kallymenia pertusa are re- ported and described for the first time.
