Abstract A variety of criteria may influence the efficacy networks marine protected areas (MPA) designed to enhance biodiversity conservation and provide fisheries benefits. Meta‐analyses have evaluated MPA attributes on abundance, biomass, size structure harvested species, reporting that size, age, depth, connectivity strength responses. However, few empirical evaluation studies used consistent sampling methodology across multiple MPAs years. Our collaborative research program...
Abstract Marine protected areas (MPAs) globally serve conservation and fisheries management goals, generating positive effects in some marine ecosystems. Surf zones sandy beaches, critical ecotones bridging land sea, play a pivotal role the life cycles of numerous fish species as prime for subsistence recreational fishing. Despite their significance, these remain understudied when evaluating MPAs. We compared surf zone assemblages inside outside MPAs across 3 bioregions California (USA)....
Sandy beach/surf-zone ecosystems are unique environments that, despite the harsh and highly variable hydrodynamic conditions, present a diverse heterogeneous fauna. However, dynamics of these currently poorly understood. In this study we tested hypothesis that surf-zone assemblages vary with temporal factors such as time day, tide tidal height. To test hypothesis, community Bastendorff, Southern Oregon sandy beach was sampled during summer 2006. Samples were collected to (i) describe...
The Gulf of Guayaquil, the largest estuary on Pacific coast South America, provides livelihoods for fishing communities that supply seafood to national markets.Activities like mining and agriculture are major sources contamination in estuary, yet their effects ecosystem have not been determined.Publicly-available data were compiled provide an overview level water, sediment this system.Measured concentrations (Cm) compared with corresponding permitted levels (Csl) defined international...
Abstract Habitat heterogeneity can influence biological communities by providing a diversity of areas that be occupied different species. Sandy beach surf zones are often considered homogenous environments; however, sand bars moved currents and waves produce trench‐like shapes or troughs provide heterogeneity. The habitat produced movement is unclear despite the fact an important for larval juvenile fish macrocrustaceans. To determine if, how, macroinvertebrate present in trough non‐trough...
The smooth bay shrimp, Lissocrangon stylirostris, was sampled using a beach seine and hyperbenthic sledge in the summer of 2006 at dissipative sandy southern Oregon. We investigated possible variations population structure due to environmental variables, preferred prey, sexual system employed, impacts parasitism by bopyrid isopod Argeia pugettensis, predators. 63% female, females were generally larger than males. density L. stylirostris varied significantly with time day. A cohort small...
Temperate and subtropical sandy beach surf zones present diverse abundant fauna that are important in local food webs. However, dynamics of these have been poorly studied tropical areas. The aims the study were to describe small swimming surf-zone (~1–5mm length) two Ecuadorian beaches, determine whether this varies with beach, season or tide, explore environmental factors correlated faunal variability. Beaches sampled wet dry seasons during high, mid- low tide (2001–2002) by using a...
Marine fish populations can be vulnerable to overfishing, as a response of their life history, ecology, and socio-economic aspects. Vulnerability assessments, in this regard, used support fisheries decision-making by aiding species prioritization. Assessments like Productivity–Susceptibility Analyses are well suited for multispecies fisheries, with low gear selectivity insufficient fishery-independent dependent data. Using method, we assessed local vulnerability the Galapagos grouper...
RESUMEN.La zona de rompiente playas arenosas presenta una alta diversidad faunística y es criadero para peces crustáceos.Las corvinas (Cynoscion spp.) son eurihalinos importancia comercial ecológica cuyas larvas usan las zonas rompiente, sin embargo su biología poco conocida.Se determinó el uso estudiando la presencia, densidad crecimiento corvina en playa arenosa ecuatoriana adyacente al sistema estuarino más grande del oeste Sudamérica se exploró relaciones estos tres factores con...
The Mottled Scorpionfish (Pontinus clemensi) is an ecologically and economically important species endemic to the Eastern Tropical Pacific. Despite its importance, little known about life history traits. In order close this knowledge gap, we analyzed otoliths gonads describe age reproduction, fit von Bertalanffy, logistic, Gompertz growth models, selected most parsimonious model using Akaike Information Criterion. We collected 420 samples from fishing trips throughout archipelago fish landed...
Sea-level rise (SLR) is and will continue to be a pressing issue in the rural, North Coast region of California, especially since nearby Wigi (or Humboldt Bay) experiencing one fastest rates relative SLR on U.S. West Coast. In this paper, we argue that presents transformative opportunity rekindle environmental relationships reshape future California beyond. As preeminent higher education institution region, Cal Poly has responsibility leader education, research, planning for climate...
El Niño events heavily influence physical characteristics in the Tropical Eastern Pacific and lead to a decrease nutrient phytoplankton concentrations variation composition of marine trophic chain. However, can also provide an opportunity evaluate possible effects climate change may have on ecosystems. The Galapagos Marine Reserve coastal fin-fish fishery supports approximately 400 fishers that target species include benthic/demersal predatory fish such as endemic whitespotted sandbass (...
