This book was released on 1976 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Several study areas were investigated at two Port Colborne terneries during the summers of 1973 and 1974 in an attempt to determine the influence of clutch size, time of clutch initiation, position in the colony, proximity to Ring-billed Gulls, vegetation and nesting substrate on the reproductive performance of the Common Tern. Hatching success and reproductive success (the number of chicks fledged per egg laid) were generally higher for 3-egg than 2-egg clutches but fledging (the number of chicks fledged per egg hatched) success was usually independant of clutch size. Hatching, fledging and reproductive success declined as a function of time of clutch initiation. Mean clutch sizes also generally declined as a function of time. Nests located in the center of the colony exhibited higher fledging success than those on the periphery. Rock-based clutches had a lower hatching success than clutches initiated on sand or dried vegetation. Reproductive performance did not appear to be related to proximity to Ring-billed Gulls or vegetation within the study area.

This book was released on 2007-11-25 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine, coastal and wetland habitats are threatened, through exploitation, and also by climate change, as ocean currents change course, sea levels rise, and rainfall patterns change. This book gathers papers on the biodiversity conservation of these increasingly threatened habitats. The papers provide a snapshot of the problems they face, and offer numerous examples which render this volume valuable to educators in marine, freshwater and wetlands ecology, conservation and ecological restoration.

This book was released on 2017-02-23 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: The existing theories on the evolution of senescence assume that senescence is inevitable in all organisms. However, recent studies have shown that this is not necessarily true. A better understanding of senescence and its underlying mechanisms could have far-reaching consequences for conservation and eco-evolutionary research. This book is the first to offer interdisciplinary perspectives on the evolution of senescence in many species, setting the stage for further developments. It brings together new insights from a wide range of scientific fields and cutting-edge research done on a multitude of different animals (including humans), plants and microbes, giving the reader a complete overview of recent developments and of the controversies currently surrounding the topic. Written by specialists from a variety of disciplines, this book is a valuable source of information for students and researchers interested in ageing and life history traits and populations.

Book excerpt: Reproductive Success of Nesting Terns and Black Skimmers on the Central Texas Coast (October, 2013). Rachel R. Fern, B.S., Texas State University M.S., Texas A&M University-Corpus Christi Chair of Advisory Committee: Dr. Kim Withers Seabirds are top predators at sea and are particularly sensitive to changes in the marine environment. This gives them significant potential as bioindicators of the current state of and shifts in marine ecosystems. Nest site selection is important because the demands of reproduction can be substantial and the reproducing pair is often confined to the area selected for the duration of the breeding season. Location of the nest in relation to vegetative cover, colony density and richness can strongly influence reproductive success via exposure to predators or weather events and competition for food resources and optimal nest sites. Additionally, the timing of nesting in the breeding season can influence the outcome of the breeding effort due to storm events and increasing ambient temperatures. This study defines temporal effects and correlations between reproductive success of nesting terns and skimmers and environmental characteristics of the nest site: area (ha), vegetative coverage, Spartina spp. coverage, elevation, nest density, assemblage richness and human disturbance. The four species included in this research (Forster's Tern Sterna forsteri, Gull-billed Tern Gelochelidon nilotica, Least Tern Sternula antillarum and Black Skimmer Rhynchops niger) were monitored at various nesting sites during the 2012 and 2013 breeding seasons. Reproductive success of Forster's Terns seemed to be influenced by human disturbance, nest density and species richness of the nest site. Elevation and Spartina spp. coverage both positively influenced the success of Least Terns. The nesting success of Gull-billed Terns was positively correlated with elevation and species richness of the nest site, and success of Black Skimmers was negatively correlated with species richness and positively correlated with elevation. All species that nested early in the breeding season suffered nest failure due to storm events; however, Gull-billed Terns were only marginally impacted. Establishing these correlations in environmental nest site characteristics and reproductive success of nesting terns and skimmers provides a baseline understanding of tern and skimmer breeding biology in the central Coastal Bend region of Texas, which may assist future management decisions and restoration efforts.
