Toward a Restoration Protocol for Mediterranean Red Coral: Incorporating Life History Traits, Genetics, Demography, and Experimental Approaches
… and better describe the ecological trajectory of early life history stages of C. rubrum (Chapter 2); and (2) genetics, trying to highlight the importance of incorporating genetic diversity into restoration efforts (Chapter 3). Thanks to an approach that included in-situ and ex-situ …

Influence of Natural and Anthropogenic Environmental Variability on Larval Fish Diet, Growth, and Condition in the Northcentral Gulf of Mexico
… River and Mobile Bay, among other sources. Early life history stages of fishes are especially vulnerable to environmental variability created by freshwater discharge. The objectives of this study were to describe the available prey field, diet, growth and condition of larval fishes with …

Impacts of sedimentation on early-life phenotypes and gene expression in coho salmon (Oncorhynchus kisutch)
Early-life environmental stressors may threaten species of conservation concern by impacting populations during vulnerable early life history stages. Here, I tested some of the effects of sediment stress and hypoxia during early-life development on phenotypic outcomes and gene expression in coho …

Changes in midgut gland morphology and digestive enzyme activities associated with development in early stages of the American lobster Homarus americanus
… to the midgut gland (hepatopancreas). in early life history stages of the American lobster Homarus americanus is examined in the present study by means of two separate but complementary approaches. A histological study on the light microscope level details the morphological changes which …

Ecological, Social, And Educational Dimensions Of Restoration: Insights From Berenty Reserve, Madagascar
… impacts of light and water availability on its early life history stages, showing that light is the most limiting resource for tamarind growth and that water availability impacts tamarind more than water frequency. I also addressed management alternatives of the invasive vine Cissus …

Ecology of the Early Life History of the Caribbean Spiny Lobster, <i>Panulirus argus:</i> Recruitment, Predation, and Habitat Requirements
<p>Recruitment variability of the early life history stages of marine benthic organisms can have profound consequences on population dynamics. I studied factors affecting recruitment success of postlarvae and early juveniles of the Caribbean spiny lobster. I examined patterns in postlarval supply, …

Post-settlement processes and early life history dynamics of zebra mussels (Dreissena polymorpha) in the Hudson River estuary
… events and processes that occur to visible adult stages, particularly those of economically important species, in most cases we know very little or nothing about processes occurring to early life history stages. One of the main barriers to our understanding is a lack of empirical data on young …

Egg and larval ecology of anchovy (Engraulis capensis) and sardine (Sardinops sagax) in the Southern Benguela ecosystem
… appears to be bimodal, reaching a peak in the early spring (August/September) and again in late summer (February). · Although the midshelf region on the W AB appeared to be the centre of both anchovy and ·sardine spawning in the southern Benguela ecosystem, these data suggest that anchovy and …
