Kelmartin and published by . This book was released on 2018 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: Black rockfish (Sebastes melanops), canary rockfish (S. pinniger), and lingcod (Ophidion elongatus) are important species in Northern California's nearshore recreational and commercial fisheries. These species are associated with nearshore rocky reefs and are among a suite of species intended to benefit from the establishment of the marine protected area (MPA) network along the Northern California Coast in 2012. Many aspects of the North Coast's nearshore ecosystem remain poorly studied, including the spatial distribution and habitat associations of nearshore fish species. This study used data collected from Cape Mendocino State Marine Reserve (SMR), Ten Mile SMR, and paired, nearby reference sites to investigate the habitat associations of black rockfish, canary rockfish, and lingcod on the North Coast by generating Maxent habitat suitability models for each species. This study showed black rockfish associated with high relief, rocky habitat, less than ~30 meters in depth, lingcod associated with rocky habitat, independent of relief, deeper than 20 meters, and canary rockfish associated with high relief rocky habitat, deeper than ~35 meters. The findings of this study also investigated and supported the findings of a previous study that found canary rockfish associated with the edge of rocky reef and sandy habitats. Maxent modeling can increase manager's understanding of the habitat used by marine fishes and inform the establishment of MPAs, designation of Essential Fish Habitat, and regional catch limits by identifying where habitat might support more productive populations, especially for poorly studied stocks.
Download or read book Characterizing and Quantifying Habitat Heterogeneity Extinction and Persistence of Habitat Preference in Phanerozoic Reefs written by Peter Ward Tierney and published by . This book was released on 2018 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: Habitat heterogeneity is understood to be a primary driver of taxonomic diversity in modern reefs, and is assumed to have acted similarly throughout the Phanerozoic history of reef-building. However, there is no established methodology to measure heterogeneity in fossil reefs, and the rock record presents many challenges to doing so, including issues of preservation, exposure, and time-averaging. Here, I present five quantitative and semiquantitative methods that can be applied to fossil reefs in order to characterize heterogeneity. These include the complexity and diversity of reef-builder morphotypes involved in reef construction, the number of distinct reef facies, the scale of relief the reef achieved in life, and a Structural Complexity Index (SCI) calculated using the dimensions of framework elements encountered along a transect. These metrics are applied to Ordovician and Pleistocene reefs, and biases of each metric are discussed in detail. These metrics are then applied to reefs across the middle-Paleozoic to assess how heterogeneity changed over the interval, as reefs became more diverse. Through this interval, reefs became larger, exhibiting greater relief, a wider array of reef-builder morphotypes, and a higher diversity of reef facies. The final chapter addresses the identity of a cohesive reef fauna in deep time, using reef crises as natural experiments to examine extinction and persistence of reefal preference for reef-builders and reef-dwellers across the Phanerozoic. Reefal taxa exhibit lower extinction than nonreefal taxa, consistent with having more eurytopic environmental distribution. Reef-builders and reef-dwellers do not exhibit significant differences in extinction, but reef-builders express significantly higher rates of persistence in reefal habitats. Reef-builders and reef-dwellers do not exhibit consistent responses to episodes of reef crisis, perhaps due to variation in the drivers of each reef crisis. Nevertheless, reef-builders and -dwellers do not respond to perturbations in similar ways, and should be addressed separately when analyzing diversity dynamics of reefal taxa.
Download or read book Characterizing Reef Fish in the Gulf of Mexico Using Environmental DNA Metabarcoding written by Juliana Giraldo-Meneses and published by . This book was released on 2021 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: A wide range of environmental pressures and anthropogenic stressors, such as overfishing, climate change, and coastal development, have negatively affected fish communities in the Gulf of Mexico, specifically reef fish inhabiting natural or artificial reefs. Fish communities in the Gulf of Mexico vary both spatially and temporally due to movements in the water column, migrations, and environmental pressures making conventional survey sampling challenging to perform. Conventional methods can often be costly, time-consuming and invasive to the target organism. A possible resolution to overcome these challenges to inventory reef fish species lies with environmental DNA (eDNA) metabarcoding. Water samples were collected from artificial and natural reefs in the Gulf of Mexico. The 12s rRNA mitochondrial gene was amplified using elasmobranch and MiFish primers. Only elasmobranch primers were able to provide valuable reads. Amplicon libraries generated by PCR were sequenced using Illumina HiSeq. Environmental DNA metabarcoding revealed 4 reef-associated species out of 12 detected species, the Rough scad (Trachurus lathami), Sand diver (Synodus intermedius), Pearly razorfish (Xyrichtys novacula) and the invasive Lionfish (Pterois spp.). Fish species detections across nine sites were grouped by habitat and IUCN status. Surface and benthic fish detections were grouped by temperature and salinity. A generalized linear model and linear regression were used to test for correlation. This project demonstrates the utility of eDNA and metabarcoding as a valuable tool for characterization of reef fish species in the Gulf of Mexico.

Download or read book Habitats and Biota of the Gulf of Mexico Before the Deepwater Horizon Oil Spill written by C. Herb Ward and published by Springer. This book was released on 2017-06-26 with total page 948 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is open access under a CC BY-NC 2.5 license. The Gulf of Mexico is an open and dynamic marine ecosystem rich in natural resources but heavily impacted by human activities, including agricultural, industrial, commercial and coastal development. The Gulf of Mexico has been continuously exposed to petroleum hydrocarbons for millions of years from natural oil and gas seeps on the sea floor, and more recently from oil drilling and production activities located in the water near and far from shore. Major accidental oil spills in the Gulf are infrequent; two of the most significant include the Ixtoc I blowout in the Bay of Campeche in 1979 and the Deepwater Horizon Oil Spill in 2010. Unfortunately, baseline assessments of the status of habitats and biota in the Gulf of Mexico before these spills either were not available, or the data had not been systematically compiled in a way that would help scientists assess the potential short-term and long-term effects of such events. This 2-volume series compiles and summarizes thousands of data sets showing the status of habitats and biota in the Gulf of Mexico before the Deepwater Horizon Oil Spill. Volume 2 covers historical data on commercial and recreational fisheries, with an analysis of marketing trends and drivers; ecology, populations and risks to birds, sea turtles and marine mammals in the Gulf; and diseases and mortalities of fish and other animals that inhabit the Gulf of Mexico.
Download or read book Ecosystem Based Fisheries Management written by Jason Link and published by Cambridge University Press. This book was released on 2010-10-07 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Responsible fisheries management is of increasing interest to the scientific community, resource managers, policy makers, stakeholders and the general public. Focusing solely on managing one species of fish stock at a time has become less of a viable option in addressing the problem. Incorporating more holistic considerations into fisheries management by addressing the trade-offs among the range of issues involved, such as ecological principles, legal mandates and the interests of stakeholders, will hopefully challenge and shift the perception that doing ecosystem-based fisheries management is unfeasible. Demonstrating that EBFM is in fact feasible will have widespread impact, both in US and international waters. Using case studies, underlying philosophies and analytical approaches, this book brings together a range of interdisciplinary topics surrounding EBFM and considers these simultaneously, with an aim to provide tools for successful implementation and to further the debate on EBFM, ultimately hoping to foster enhanced living marine resource management.

Available in PDF, EPUB and Kindle. Book excerpt: Kupe and the Corals is the story of Kupe, a young boy who undertakes an amazing voyage of discovery to learn about corals and the importance of coral reefs to all of the many animals that depend upon them. One night while he is fishing with his father, Kupe observes an astonishing event, thousands and thousands of tiny “bubbles” rising to the surface of the waters in the lagoon near where he lives. Kupe is amazed by this sight and wants to learn more about the “strange pink bubbles” that he has captured in an old jam jar. Kupe visits with an elder from his village and a scientist from the nearby marine lab in an attempt to learn more about what he has seen. During his conversations, Kupe learns that what he has captured are tiny coral larvae, baby corals that are produced in the millions over just a few nights each year by the adult corals living in the lagoon. Kupe then goes on to learn more about how corals grow and the importance of corals in building the reefs that provide homes for all of the other wonderful animals that he sees while snorkeling in the lagoon. Now, realizing how important the larvae he has captured are to the health of the coral reef, Kupe happily returns his larvae to the sea. Kupe and the Corals, is the sixth book in the Long Term Ecological Research Network Series.
