Using Drift Video Transects and Maximum Likelihood Geostatistics for Quantifying and Monitoring Exploited Subpopulations of Loxechinus albus at a Mesoscale
Abstract Population monitoring of benthic species has been complicated by difficulties in defining appropriate spatial units for making observations that are relevant to the management of these

Development and characterization of EST-microsatellites for the edible sea urchin Loxechinus albus using next generation sequencing
The Loxechinus albus is the only sea urchin exploited for commercial fisheries and is an important component of communities across southeastern Pacific coast, and a total of 463 putative microsatellite loci were identified in silico.
Challenges for coastal zoning and sustainable development in the northern Patagonian fjords (Aysén, Chile)
The Chilean government in 1994 enacted its National Policy for the Use of the Coastal Fringe (NPUCF) to promote sustainable development within the context of international requirements. One of the


Status and management of world sea urchin fisheries
Sea urchin fisheries have potentially large ecological effects, usually mediated through increases in the abundance and biomass of large brown algae, and although such effects may have important consequences for management of these and related fisheries, only in Nova Scotia, South Korea and Japan is ecological knowledge incorporated into management.
Physical influences on recruitment to California Current invertebrate populations on multiple scales
Studies of recruitment to Dungeness crab (Cancer magister) and red sea urchin (Strongylocentrotus franciscanus) populations have focused on recruitment variability on interannual, 1000-km scales.
Reproductive variability over a four-year period in the sea urchin Evechinus chloroticus (Echinoidea: Echinodermata) from differing habitats in New Zealand
The endemic New Zealand echinoid, Evechinus chloroticus, was sampled approximately monthly from September 1990 to October 1994 at three sites in Tory Channel, Marlborough Sounds, New Zealand, showing an annual reproductive cycle, with gametogenesis commencing in the late austral winter and spawning in summer.
Reproduction of sea urchin Loxechinus albus in Chiloé Island, Chile
The sea urchins matured in January and February immediately after spawning at many sites and a high percentage of maturation lasted for a long period at some sites, considered to be associated with high food availability and annual narrow ranges of water temperature.
Reproduction strategies of Macrocystis pyrifera (Phaeophyta) in Southern Chile: The importance of population dynamics
The results show that M. pyrifera present in wave-exposed locations has a reproductive strategy that is similar to populations in the northern hemisphere, and these populations reproduce all year round.

Sources, Sinks, and Population Regulation

If the surplus population of the source is large and the per capita deficit in the sink is small, only a small fraction of the total population will occur in areas where local reproduction is sufficient to compensate for local mortality, and the realized niche may be larger than the fundamental niche.
