Benthic macroinvertebrates are commonly included in studies to monitor the effects of human and natural stresses on marine and estuarine ecosystems. There are several reasons for this. Macroinvertebrates (here defined as animals retained on a 0.5-mm mesh sieve) are abundant in most coastal and estuarine sediments, typically on the order of 103 to 104 per meter squared. Benthic communities are typically composed of many taxa from different phyla, and quantitative measures of community diversity (e.g., Rosenberg et al. 2004) and the relative abundance of animals with different feeding behaviors (e.g., Weisberg et al. 1997, Pelletier et al. 2010), can be used to evaluate ecosystem health. Because most benthic invertebrates are sedentary as adults, they function as integrators, over periods of months to years, of the properties of their environment.

  • Molluscan (Gastropoda and Bivalvia) Diversity and Abundance in Rocky Intertidal Areas of Lugait, Misamis Oriental, Northern Mindanao, Philippines
    J. Bio. & Env. Sci. 2017 Journal of Biodiversity and Environmental Sciences (JBES) ISSN: 2220-6663 (Print) 2222-3045 (Online) Vol. 11, No. 3, p. 169-179, 2017 http://www.innspub.net RESEARCH PAPER OPEN ACCESS Molluscan (Gastropoda and Bivalvia) diversity and abundance in rocky intertidal areas of Lugait, Misamis Oriental, Northern Mindanao, Philippines Shirlamaine Irina G. Masangcay1, Maria Lourdes Dorothy G. Lacuna*2 1Department of Biology, College of Arts and Sciences, Caraga State University, Ampayon Campus National Highway, NH1, Butuan City, Philippines 2Department of Biological Sciences, College of Science and Mathematics, Mindanao State University-Iligan Institute of Technology, Iligan City, Philippines Article published on September 30, 2017 Key words: Cerithium stercusmuscarum, Drupella margariticola, total organic matter, calcium carbonate, density. Abstract Composition, diversity and abundance of rocky intertidal mollusks and their relationship with the environmental parameters, viz. water quality, total organic matter and calcium carbonate were determined. A total of 43 species were identified, of which 41 species belong to Class Gastropoda under 18 families and 2 species were categorized under Class Bivalvia from 2 families. Using several diversity indices, results revealed high diversity and equitability values in the 2 sampling sites. Moreover, comparison of the mollusks abundance between the 2 sampling stations showed station 2 to be dominantly abundant with Cerithium stercusmuscarum comprising almost one-third of the total population. Canonical Correspondence Analysis showed that total organic matter and calcium carbonate in the sediment may have influenced the abundance of mollusk assemblage in station 2. The results obtained from the study are vital in order to strongly support the need to continue monitoring the Lugait marine sanctuary and its nearby surroundings.

Lloyd1,*, Anna Metaxas1, Brad deYoung2 1Department of Oceanography, Dalhousie University, Halifax, Nova Scotia, Canada B3H 4R2 2Department of Physics and Physical Oceanography, Memorial University, St. John’s, Newfoundland, Canada A1B 3X7 ABSTRACT: Marine gastropods form a diverse taxonomic group, yet little is known about the factors that affect their larval distribution and abundance. We investigated the larval vertical dis- tribution and abundance of 9 meroplanktonic gastropod taxa (Margarites spp., Crepidula spp., Astyris lunata, Diaphana minuta, Littorinimorpha, Arrhoges occidentalis, Ilyanassa spp., Bittiolum alternatum and Nudibranchia), with similar morphology and swimming abilities, but different adult habitats and life-history strategies. We explored the role of physical (temperature, salinity, density, current velocities) and biological (fluorescence) factors, as well as periodic cycles (lunar phase, tidal state, diel period) in regulating larval vertical distribution. Using a pump, we collected plankton samples at 6 depths (3, 6, 9, 12, 18 and 24 m) at each tidal state, every 2 h over a 36 and a 26 h period, during a spring and neap tide, respectively, in St. George’s Bay, Nova Scotia. Con- currently, we measured temperature, salinity, density, fluorescence (as a proxy for chlorophyll, i.e. phytoplankton density), and current velocity. Larval abundance was most strongly related to tem- perature, except for Littorinimorpha and Crepidula spp., for which it was most strongly related to fluorescence. Margarites spp., A.
