“…However, cohort growth analysis has been widely used in field programmes directed towards the estimation of annual production of marine benthic macrofaunal species in UK waters (Buchanan & Warwick, 1974; Warwick & Price, 1975; Warwick et al ., 1978; Price & Warwick, 1980; Warwick & George, 1980; George & Warwick, 1985). Such studies typically result in a time series of size-frequency distributions, from which the demographic parameters of recruitment, growth rates and mortality rates can be derived (Crisp, 1984; Van der Meer et al ., 2013). A time series of size-frequency distributions is used to follow the progression of size-modes over time so that it is possible to determine whether the size modes are annual or not, since it is conceivable that modes could result from a series of discrete spawnings over time periods shorter than a year, or annual modes might be missing due to recruitment failure.…”

“…Several computer packages such as ELEFAN, SLCA, MULTIFAN and MULTIFAN-CL are available to identify modes in size-frequency distributions (see Van der Meer et al ., 2013 and references therein) but these are based on the assumption that the sizes in each age class are normally distributed, which is intuitively invalid. If recruitment occurs over a period of time and the recruits then begin to grow and suffer mortality then we would expect a right-skewed size distribution for that cohort (i.e.…”

Irregular recruitment of the echinoid Echinocyamus pusillus and its implications for biological traits analysis

Size-frequency analysis of the echinoid Echinocyamus pusillus from six offshore areas in the southern North Sea and eastern English Channel reveal five distinct cohorts, suggesting a lifespan of five years. In all six individual areas one or more year-groups are absent, due to the unsuccessful recruitment of planktonic larvae to the seabed in some years, giving a false impression of a shorter lifespan. A relatively long lifespan and planktotrophic larval development are remarkable for such a small species, which reaches a maximum test length of 7.3 mm in the area, such traits being more typical of large-sized macrobenthic species. The feeding mode is akin to that of many meiobenthic taxa. The architecture of the test confers exceptional strength and resilience to mechanical perturbation.

“…All specimens were dried in a Lavoisier oven at 80 ºC for 24 hours (DW1), and then burned at 550 ºC in a muffle oven for 2 hours (DW2) before respective weighting. Ash free dry weight (AFDW) was obtained by the difference between DW1 and DW2 (AFDW = DW1 -DW2) (Van Der Meer et al 2005). The population production was estimated using a size-based method (Mass Specific Growth Rate-MSGR) described by Crisp (1984).…”

SECONDARY PRODUCTION OF Scolelepis goodbodyi (POLYCHAETA: SPIONIDAE) IN A TROPICAL SANDY BEACH IN THE SOUTHWESTERN ATLANTIC, BRAZIL

The secondary production is the result of the functional response of populations subject to various environmental factors. Marine habitats vary in terms of quantity and quality of food supply, and the use of secondary production values, as well as renewal rates (P/B), may be used as estimates for understanding the incorporation of organic matter and energy per unit, population or community in each area. This estimative was performed for the population of Scolelepis goodbodyi in a tropical beach in the Southwestern Atlantic, located in an upwelling area. A comparison of Spionidae and non-spionid populations from different latitudes was also done. The Mass Specific Growth Rate method (MSGR) and the Production/Biomass ratio (P/B) were used to estimate the somatic annual production and average annual biomass. The mean density and biomass were 16.38 ind. m-2 and 2.78 g AFDW m-2,respectively. The secondary production and P/B were 8.3 g AFDW m-2 y-1 and 2.98 y1, respectively. The growth rate in weight was greater for the small size than the large size classes. The largest individuals (W3C = 1.0 mm) showed the lowest biomass and secondary production values. The observed high rates of secondary production and P/B suggest that this S. goodbodyi population can transfer large amounts of biomass to higher trophic levels of the local food web. Studies of the secondary production of spionidae populations in different latitudes, including the population of S. goodbodyi in the beach of Manguinhos, showed variability in their rates probably due to the differences of several factors such as life history and environmental variability

“…Secondary production was calculated according to the weight-increase-summation method (Van der Meer et al 2005) for the half-year periods March -August: P = Σ (n . ∆g), with n = mean numerical density (mean of March and August estimate) and ∆g = mean (uncorrected and non-averaged) individual weight change between March and August.…”

The carrying capacity of a tidal flat area for suspension-feeding bivalves

To investigate the relationship between stock size and production of an entire feeding guild, and in particular to find out whether it is dome-shaped (showing an optimal abundance for production), we used a 40-year data set of the 3 most important suspension-feeding bivalves (Cerastoderma edule, Mytilus edulis, and Mya arenaria) in a Wadden Sea tidal flat area of about 20 km 2 . The data set contained data on numerical density of individuals, annual rates of weight growth, recruitment, survival, and secondary production. At higher densities (> 400 individuals m -2 ), we found reductions of growth rate and recruitment. At the highest densities the reduction in weight growth was so strong that production was lower than its maximal values at intermediate densities. This optimal density of around 400 m -2 was considered to represent the carrying capacity of the system for suspension-feeding bivalves.High densities resulting in reduced production, however, rarely (in only 5% of the years) occurred during the 40-y monitoring period. Clear bottom-up limitation of bivalve production was thus very unusual in the studied area. Year to year variation in growth and production of suspension-feeding bivalves were not related to chlorophyll concentrations in the main tidal stream and did not follow the declining longterm trends of primary production and chlorophyll concentrations. The main conclusion of the paper is that production increases with stock size, but only to a certain threshold value that is rarely reached as a consequence of insufficient recruitment by a top-down process (predation on young stages).
