Available in PDF, EPUB and Kindle. Book excerpt: Coralline algae (Corallinophycideae) are calcifying red algae that form the foundation of many shallow marine ecosystems globally, providing settlement sites for a range of invertebrate larvae, stabilisation of reefs and habitat for grazing and cryptofaunal species. This group of macroalgae are vulnerable to increased anthropogenic disturbances, in particular ocean acidification. Despite their ecological importance and vulnerability, little is known about their diversity, distribution and ecology, globally and within New Zealand. The primary objective of this work was to document the diversity and distribution of coralline algae in New Zealand, and examine the abiotic and biotic factors potentially influencing this distribution across different spatial scales. This body of work used DNA based phylogenetic methods to identify species of corallines collected in the southern region of New Zealand, incorporating data previously collected from central and northern New Zealand. A high level of diversity was revealed in southern New Zealand (77 species identified and 99 predicted), which is in line with what is currently being uncovered globally, with diversity that is two to four times higher than previously estimates that were based on morpho-anatomical identifications. Multivariate clustering and constrained ordination techniques, grouping sites based on similarities in coralline algae community structure and relating this to selected environmental parameters, identified sea surface temperature and light at the seabed as variables significantly correlated with these community groupings across the New Zealand region. Similarly, linear model analysis identified depth, likely a proxy for light, and the type of substrate as being the most important variables explaining the abundance of coralline algae (independent of species identity) across an often overlooked biogenic environment across Foveaux Strait. At local spatial scales (10-100’s m) patterns in coralline algal community structure revealed stochastic dispersal processes likely determine which species establish, followed by competitive interactions driving differences in abundances. These local scale processes are unlikely to influence diversity patterns seen at larger scales across the New Zealand region. Furthermore, high local scale diversity was observed, with few abundant and many rare species. This research provides an important molecular framework and information on distributional patterns of coralline algae needed to further advance knowledge on this ecologically important group.

Available in PDF, EPUB and Kindle. Book excerpt: Coralline algae (Rhodophyta) are an important indicator of global environmental change in coastal ecosystem due to their global distribution and sensitivity to changing ocean climate. In temperate latitudes, coralline algae are a dominant component of macroalgae communities, are autogenic ecosystem engineers. They provide hard substrate for colonization of other marine algae and invertebrates, and food that helps sustain diverse communities of associated organisms. The metabolic processes, growth and reproduction of coralline algae heavily depend on environmental factors including light, temperature and ambient nutrients in seawater. These changes, in turn, directly affect physiological responses of coralline algae.

Available in PDF, EPUB and Kindle. Book excerpt: In this Special Issue, we address the state of the art of the systematics of the main annelid groups and the improvements in the diversity they hold, with special emphasis on the latest discoveries in well-studied areas, expeditions to unsurveyed areas or environments, or the use of novel techniques that allow for the improvement of biodiversity knowledge. We are hoping that this Special Issue will provide a platform facilitating a review of current knowledge on the subject, identifying current research problems, as well as indicating directions and research trends for the future.

Download or read book Ecology of Australian Temperate Reefs written by Scoresby Shepherd and published by CSIRO PUBLISHING. This book was released on 2013-10-23 with total page 923 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecology of Australian Temperate Reefs presents the current state of knowledge of the ecology of important elements of southern Australian sub-tidal reef flora and fauna, and the underlying ecological principles. Preliminary chapters describe the geological origin, oceanography and biogeography of southern Australia, including the transitional temperate regions toward the Abrolhos Islands in the west and to Sydney in the east. The book then explains the origin and evolution of the flora and fauna at geological time scales as Australia separated from Antarctica; the oceanography of the region, including principal currents, and interactions with on-shelf waters; and the ecology of particular species or species groups at different trophic levels, starting with algae, then the ecological principles on which communities are organised. Finally, conservation and management issues are discussed. Ecology of Australian Temperate Reefs is well illustrated with line drawings, figures and colour photographs showing the many species covered, and will be a much valued reference for biologists, undergraduates, and those interested and concerned with reef life and its natural history. 2014 Whitley Award Commendation for Marine Ecology.

This book was released on 2013-10-22 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: International Review of General and Experimental Zoology, Volume 4 discusses the epibranchial organs in lower teleostean fishes, an example of structural adaptation; the aging and regression in the colonial marine hydroid Campanularia flexuosa, with special reference to senescence in hydroids; and the structure and characteristics of avian egg shells. The text also describes tissue mast cell and wound healing; the quantitative aspects of neurohistology; and the concept of the rods and cones approach. The strong relationships between the feeding behavior of marine organisms and biological conditions expressed in evolutionary terms are also considered. Zoologists, physiologists, biochemists, and people involved in the study of fish and wildlife services will find the book invaluable.
