Understanding how future ocean conditions will affect populations of marine species is integral to predicting how climate change will impact both ecosystem function and fisheries management. Fish population dynamics are driven by variable survival of the early life stages, which are highly sensitive to environmental conditions. As global warming ge...
Otolith microstructure analysis provides critical biological and ecological information about the early life history of fishes. This information is particularly important to interpret and predict population dynamics for socio-economically important fisheries species; however, several key assumptions underpin the use of otolith techniques. We valida...
Measuring the spatial distribution of microparticles which include synthetic, semi-synthetic, and anthropogenic particles is critical to understanding their potential negative impacts on species. This is particularly important in the context of microplastics, which are a form of microparticle that are prevalent in the marine environment. To facilit...
The draft Global Biodiversity Framework proposes to increase protected areas and OECMs to at least 30 per cent of land and ocean by 2030 (30x30). Such areas are central to conservation, but only if effectively managed and equitably governed. In practice, governments often recognise areas that do not achieve successful outcomes or respect human righ...
Marine protected areas (MPAs) are a key tool for achieving goals for biodiversity conservation and human well-being, including improving climate resilience and equitable access to nature. At a national level, they are central components in the U.S. commitment to conserve at least 30% of U.S. waters by 2030. By definition, the primary goal of an MPA...
Kelp forests line a quarter of the world’s coastlines and provide diverse ecosystem services. While kelps are a harvested resource themselves, they are also foundation species that form the basis of productive ecosystems. Globally, kelps are threatened by a variety of anthropogenic impacts, including overharvesting, overgrazing, invasive species, p...
Consistency in conservation
Marine protected areas (MPAs) are now well established globally as tools for conservation, for enhancing marine biodiversity, and for promoting sustainable fisheries. That said, which regions are labeled as MPAs varies substantially, from those that full protect marine species and prohibit human extraction to those that...
Life has evolved in the ocean for 3.7 billion years, resulting in a rich ‘ocean genome’, the ensemble of genetic material present in all marine biodiversity, including both the physical genes and the information they encode. Rapid advances in sequencing technologies and bioinformatics have enabled exploration of the ocean genome and are informing i...
The ‘ocean genome’ is the foundation upon which
all marine ecosystems rest and is defined here as the
ensemble of genetic material present in all marine
biodiversity, including both the physical genes and the
information they encode. The dynamics of the ocean
genome enable organisms to adapt to diverse ecological
niches and changing environmental c...
As 2020 approaches, countries are accelerating their commitments to protect 10% of the ocean by establishing and expanding marine protected areas (MPAs) and other area-based protections. Since it began in 2014, the Our Ocean Conference (OOC) has become a high-profile platform to announce ocean commitments. To evaluate the impact of these promises,...
Growth is key to the survival of fishes during their early life and ultimately affects annual recruitment to adult populations. To evaluate early life history traits of two commercially harvested fishes, splitnose (Sebastes diploproa) and redbanded (S. babcocki) rockfishes, we examined the otolith microstructure of juveniles of both species that se...

Marine protected areas (MPAs) form the cornerstone of marine conservation. Identifying which factors contribute to their success or failure is crucial considering the international conservation targets for 2020 and the limited funds generally available for marine conservation. We identified common factors of success and/or failure of MPA effectiven...
For most benthic marine organisms, settlement of pelagic offspring to bottom-associated habitats is a necessary step in the replenishment of adult populations. Quantifying spatial and temporal variation in settlement is therefore important to fully understand population dynamics, inform fisheries management targets, and design effective spatial man...
The United Nations’ target for global ocean protection is 10% of the ocean in Marine Protected Areas (MPAs) by 2020. There has been remarkable progress in the last decade, and some organizations claim that 7% of the ocean is already protected and that we will exceed the 10% target by 2020. However, currently only 3.6% of the ocean is in implemented...
Marine protected areas (MPAs) are a cornerstone of marine conservation. Globally, the number and coverage of MPAs are increasing, but MPA implementation lags in many human-dominated regions. In areas with intense competition for space and resources, evaluation of the effects of MPAs is crucial to inform decisions. In the human-dominated Mediterrane...
As the contribution for long-term ecological and environmental studies (LTEES) to our understanding of how species and ecosystems respond to a changing global climate becomes more urgent, the relative number and investment in LTEES are declining. To assess the value of LTEES to advancing the field of ecology, we evaluated relationships between cita...
Marine protected areas (MPAs) have been established around the world, including throughout the Mediterranean Sea. Scientific research shows that MPAs consistently produce ecological, economic, and social benefits when they include fully protected areas and are well-designed and well-managed.
This booklet summarizes the scientific evidence that sho...
Significance
Larval dispersal in the ocean is thought to be highly diffusive, but the pathways larvae follow during their pelagic stage are largely unknown, as direct tracking of larvae in the open ocean is not yet possible. We provide the first evidence of continuous aggregation of fish larvae over extensive periods in an oceanographically complex...
Mature science reveals opportunities for policy progress.
An age-old conflict around a seemingly simple question has resurfaced: why do we conserve nature? Contention around this issue has come and gone many times, but in the past several years we believe that it has reappeared as an increasingly acrimonious debate between, in essence, those who argue that nature should be protected for its own sake (intr...
Anthropogenic impacts are increasingly affecting the world's oceans. Networks of marine protected areas (MPAs) provide an option for increasing the ecological and economic benefits often provided by single MPAs. It is vital to empirically assess the effects of MPA networks and to prioritize the monitoring data necessary to explain those effects. We...
An individual's phenotype will usually influence its probability of survival. However, when evaluating the dynamics of populations, the role of selective mortality is not always clear. Not all mortality is selective, patterns of selective mortality may vary, and it is often unknown how selective mortality compares or interacts with other sources of...
Selective mortality is an important process influencing both the dynamics of marine populations and the evolution of their life histories. Despite a large and growing interest in measuring selective mortality, studies of marine species can face some serious methodological and analytical challenges. In particular, many studies of selection in marine...
The ecologically and socio-economically important marine ecosystems of Europe are facing severe threats from a variety of human impacts. To mitigate and potentially reverse some of these impacts, the European Union (EU) has mandated the implementation of the Marine Strategy Framework Directive (MSFD) in order to achieve Good Environmental Status (G...
Coral reef fish recruitment to the upper Florida Keys was monitored monthly for 7 years (2003–2009) to establish a baseline and test whether recruitment varied between reserve and non-reserve sites. Recruits <30 days old were surveyed in two primary habitat types (reef and rubble) in each of two replicate reserve and non-reserve sites. Recruitment...
Background/Question/Methods
Both ecological theory and empirical data demonstrate that recruitment of marine species is highly variable in space and time as complex biological and oceanographic factors influence the transport and survival of larvae and recruits. The mosaic of recruitment patterns that occur along a coast can provide a particular...
Human-induced environmental disturbance – through fishery activities, coastal development, tourism and pollution – is a major challenge to the restoration and conservation of marine biodiversity. Synthesizing the latest research into marine biodiversity conservation and fisheries management, this book provides regional and global perspectives on th...

As animals with complex life cycles metamorphose from one stage to the next, carry-over effects from earlier stages can affect future mortality. To examine the relationship between early life history traits and survival, seven monthly cohorts of newly-settled bluehead wrasse Thalassoma bifasciatum were collected immediately after settlement and ove...
The Partnership for Interdisciplinary Studies of Coastal Oceans (PISCO) produced the Science of Marine Reserves booklets in collaboration with the Communication Partnership for Science and the Sea (COMPASS, www.compassonline.org). PISCO is a consortium of academic scientists Stanford University. PISCO advances the understanding of coastal marine ec...
As human impacts cause ecosystem-wide changes in the oceans, the need to protect and restore marine resources has led to increasing calls for and establishment of marine reserves. Scientific information about marine reserves has multiplied over the last decade, providing useful knowledge about this tool for resource users, managers, policy makers,...
The field of marine reserve science has matured greatly over the last decade, moving beyond studies of single reserves and beyond perspectives from single disciplines. This Special Feature exemplifies recent advances in marine reserve research, showing insights gained from synthetic studies of reserve networks, long-term changes within reserves, in...

The search for generality in ecology should include assessing the influence of studies done in one system on those done in other systems. Assuming generality is reflected in citation patterns, we analyzed frequencies of terrestrial, marine, and freshwater citations in papers categorized as terrestrial, marine and freshwater in high-impact “general”...
Background/Question/Methods
The search for generality in ecology should include assessing the influence of studies done in one system on those done in other systems. Assuming that this form of generality, here termed “habitat” generality, would be expressed in citations of research papers, we sampled and analyzed frequencies of terrestrial, marine...
The study and implementation of no-take marine reserves have increased rapidly over the past decade, providing ample data on the biological effects of reserve protection for a wide range of geographic locations and organisms. The plethora of new studies affords the opportunity to re- evaluate previous findings and address formerly unanswered questi...
For marine organisms, decoupling between the planktonic larval stage and the benthic-associated juvenile stage can lead to
variable patterns of population replenishment, which have the potential to influence the effectiveness of marine reserves.
We measured spatial and temporal variability in larval supply and recruitment of fishes to coral reefs o...
For newly settled coral reef fishes, survival advantages may be associated with specific early life history traits or condition levels that lead to differences in behavior. To identify physiological and behavioral characteristics associated with different condition levels, bluehead wrasse Thalassoma bifasciatum recruits were collected immediately a...
For benthic marine organisms with complex life cycles, conditions experienced by pelagic larvae can influence juvenile survival. Trait-specific selective mortality has been documented in the laboratory and field, yet our knowledge of the factors contributing to the existence, strength, and consistency of natural selective mortality is limited. We c...
Thirteen cohorts of the Caribbean reef fish Thalassoma bifasciatum were collected over 4 yr (2000 to 2003) in the upper Florida Keys, USA. Juvenile fish were censused and collected from replicate reefs shortly after settlement. The otoliths were examined to obtain early life history information Such as timing of spawning, larval growth, pelagic lar...
Higher densities of piscivores on reefs may affect the mortality of newly-settled coral reef fishes, leading to lower survival and increased selective pressure. Therefore, survivors are often individuals with advantageous traits acquired during early life. To examine the carryover effects of larval history on early juvenile survival, nine cohorts o...
Few time series collections have been made of the larval ichthyofauna in waters directly above shallow coral reefs. As a result, relatively little is known regarding the composition and temporal dynamics of larval fish assemblages in shallow-reef waters, particularly those near a major western boundary current. We conducted a series of nightly net...
Although widely distributed on rocky reefs at Santa Catalina Island (southern California, USA), the small, substrate-oriented fish, Lythrypnus dalli, often reaches its highest densities in areas of extreme vertical relief where the sea urchin, Centrostephanus coronatus, is common. Through surveys and manipulative field experiments, we examined the...
