The management and conservation of the world's oceans require synthesis spatial data on distribution intensity human activities overlap their impacts marine ecosystems. We developed an ecosystem-specific, multiscale model to synthesize 17 global sets anthropogenic drivers ecological change for 20 Our analysis indicates that no area is unaffected by influence a large fraction (41%) strongly affected multiple drivers. However, areas relatively little impact remain, particularly near poles....
Kelp forests are phyletically diverse, structurally complex and highly productive components of coldwater rocky marine coastlines. This paper reviews the conditions in which kelp develop globally where, why at what rate they become deforested. The ecology long archaeological history examined through case studies from southern California, Aleutian Islands western North Atlantic, well-studied locations that represent widest possible range forest biodiversity. Global distribution is...
We suggest that relatively few species attributes are of overriding importance to the structure benthic marine algal communities and these often shared among taxonomically distant species. Data from western North Atlantic, eastern Pacific Caribbean patterns in biomass, diversity dominance strikingly convergent when examined at a functional group level relative productivity herbivore-induced disturbance potentials environment. present simple graphical model provides way predict community...
Significance Kelp forests support diverse and productive ecological communities throughout temperate arctic regions worldwide, providing numerous ecosystem services to humans. Literature suggests that kelp are increasingly threatened by a variety of human impacts, including climate change, overfishing, direct harvest. We provide the first globally comprehensive analysis forest change over past 50 y, identifying high degree variation in magnitude direction across geographic range kelps. These...
Marine ecosystems are in decline. New transformational changes governance urgently required to cope with overfishing, pollution, global changes, and other drivers of degradation. Here we explore social, political, ecological aspects a transformation Chile's coastal marine resources, from 1980 today. Critical elements the initial preparatory phase were ( i ) recognition depletion resource stocks, ii scientific knowledge on ecology resilience targeted species their role ecosystem dynamics, iii...
Although crustose coralline algae (Rhodophyta, Corallinaceae) are among the most abundant marine organisms to live on hard substratum within photic zone, relatively little is known about their ecology at species level. This due in part difficulties identification; strong similarities appearance exist phylogenetically distant taxa. The study of such convergent morphological and anatomical properties corallines provides insight into interpreting adaptive value some characters or strategies...
Abstract Forage fish play a pivotal role in marine ecosystems and economies worldwide by sustaining many predators fisheries directly indirectly. We estimate global forage contributions to through synthesis of 72 published E copath models from around the world. Three distinct were examined: (i) ecological support service ecosystems, (ii) total catch value (iii) other commercially targeted predators. use varied exhibited patterns across latitudes ecosystem types. supported kinds predators,...
Global-scale deteriorations in coral reef health have caused major shifts species composition. One projected consequence is a lowering of carbonate production rates, potentially impairing growth, compromising ecosystem functionality and ultimately leading to net erosion. Here, using measures gross erosion from 19 Caribbean reefs, we show that contemporary rates are now substantially below historical (mid- late-Holocene) values. On average, current reduced by at least 50%, 37% surveyed sites...
Coral mortality has increased in recent decades, making coral recruitment more important than ever sustaining reef ecosystems and contributing to their resilience.This review summarizes existing information on ecological factors affecting scleractinian recruitment.Successful requires the survival of offspring through sequential life history stages.Larval availability, successful settlement, post-settlement growth are all necessary for addition new individuals a ultimately maintenance or...
Field and laboratory experiments were conducted on the effect of habitat architecture (the number, size, shape, arrangement habitable spaces structures) created by benthic algae selection an abundant mobile amphipod, Gammarellus angulosus, central coast Maine. Amphipod population density body size determined in different morphologies that provided amphipods with architectures. The two primary components this system spatial number between fronds) structural length, width fronds). These...
ABSTRACT In this article, a collaborative effort between archaeologists and marine ecologists, we discuss the role kelp forest ecosystems may have played in facilitating movement of maritime peoples from Asia to Americas near end Pleistocene. Growing cool nearshore waters along rocky coastlines, forests offer some most productive habitats on earth, with high primary productivity, magnified secondary three-dimensional habitat supporting diverse array organisms. Today, extensive are found...
Abstract: Unsustainable fishing simplifies food chains and, as with aquaculture, can result in reliance on a few economically valuable species. This lack of diversity may increase risks ecological and economic disruptions. Centuries intense have extirpated most apex predators the Gulf Maine (United States Canada), effectively creating an American lobster (Homarus americanus) monoculture. Over past 20 years, marine resources harvested has declined by almost 70%. Today, over 80% value Maine's...
Maintaining coral reef ecosystems is a social imperative, because so many people depend on reefs for food production, shoreline protection, and livelihoods. The survival of this century, however, threatened by the mounting effects climate change. Climate mitigation foremost essential action to prevent ecosystem collapse. Without it, will become extremely diminished within next 20–30 years. Even with strong mitigation, existing conservation measures such as marine protected areas fisheries...
