A major challenge for small-scale fisheries management is high spatial variability in the demography and life history characteristics of target species. Implementation of local management actions that can reduce overfishing and maximize yields requires quantifying ecological heterogeneity at small spatial scales and is therefore limited by available resources and data. Collaborative fisheries r...

—We analyzed the dynamics of eight populations of anadromous alewife Alosa pseudoharengus to determine their habitat carrying capacity, their maximum reproductive rate, and whether depensation occurs at low abundances. When spawner–recruit models are fit to data sets for individual alewife populations, the resulting parameter estimates are often poorly determined, biologically unrealistic, and ...

The Assessment of Recruit Motivation and Strength (ARMS) Study was conducted at six Military Entrance Processing Sites during 2005-2006. The objectives were to compare morbidity and attrition of Army accessions who exceeded body fat (EBF) accession standards compared to weight for height or body fat qualified (WQ) and to compare among the WQ subset, those who were physically fit as measured by ...

Among the several fish species comercially exploited at the Pantanal of Mato Grosso do Sul, the "pacu" (Piaractus mesopotamicus) stands as one of the most important. Information regarding its exploitation level is necessary for the proper management of its stocks. Between 1996 and 1997 data on total length of the pacu were collected on a monthly basis from specimens caught by professional and s...

background: the high resolution melting (hrm) method is a new scanning method for detecting unknown changes in dna and its advantages have persuaded researchers to recruit it as a screening method. objectives: here, we developed a hrm method to screen r188h snp (rs3218536) of xrcc2 and compared the results with a well known pcr-rflp technique. materials and methods: genomic dna samples from 350...
