Comparisons of egg size and number are made for 10 epifaunal and 16 infaunal species of shallow-water marine or estuarine gammaridean amphipods from the north-western Atlantic. Epifaunal species have significantly more, smaller eggs than infaunal species of the same size and geographic region. Strong latitudinal and seasonal effects are also evident. For several species, egg size increases and egg number decreases in populations at more northern latitudes and in populations breeding during colder seasons. The few exceptions to the above patterns may reflect unique differences in the biology of particular species. A hypothesis is proposed that adult mortality risk is correlated positively with egg number and inversely with egg size.

Population genetic structure of two congeneric deep-sea amphipod species from geographically isolated hadal trenches in the Pacific Ocean
2017, Deep-Sea Research Part I: Oceanographic Research Papers
Citation Excerpt :
Indeed, a lack of understanding of fundamental life history parameters in Paralicella makes it difficult to explain the mechanism through which gene flow is facilitated over large geographical distances between trenches. It is known that Paralicella, in line with the majority of deep sea scavenging amphipods, does not have a larval dispersal phase (Dolah and Bird, 1980) that would promote dispersal over large distances within the plankton. This would therefore point to dispersal and gene flow being mediated through either the movement of juveniles or adults.
The deep ocean trenches that comprise the hadal zone have traditionally been perceived as a series of geographically isolated and demographically independent features likely to promote local species endemism through potent natural selection and restricted dispersal. Here we provide the first descriptions of intraspecific population genetic structure among trenches from which the levels of genetic connectivity can be examined explicitly. A total of 109 individuals across two species of Paralicella amphipods (Lysianassoidea: Alicellidae) were genotyped at 16 microsatellite DNA loci. An analysis of molecular variance identified that 22% of the overall genetic variance was attributable to differences between the species and a further 7% was attributable to differences between populations. The two species showed different patterns of genetic structure, with the levels of genetic differentiation between trenches explained by geographical proximity, the geological ages of the trenches, contemporary bottom current patterns and seabed topography around the Pacific Ocean. Overall, the inferred levels of gene flow among trenches was sufficient to reject the hypothesis that they are evolutionarily independent units.
Predicting the variation in Echinogammarus marinus at its southernmost limits under global warming scenarios: Can the sex-ratio make a difference?
2014, Science of the Total Environment
Citation Excerpt :
Studies on marine invertebrates reported changes in population dynamics and reproductive biology to address stressful conditions caused by climate variations. These specific strategies involve shifts in the following factors: lifespan (Berezina and Gubelit, 2012); life cycles (Donn and Croker, 1986; Wildish, 1984; Sainte-Marie, 1991; Beaugrand et al., 2002); reproductive patterns (Van Dolah and Bird, 1980; Kolding and Fenchel, 1981; Skadsheim, 1984; Pardal et al., 2000), and sex-ratio (the proportion of males to females) (Vlasblom, 1969; Moore, 1981; Wildish, 1997; Lawrence and Soame, 2004). By exploring these effects of climate variation within a site, we can place this information in the context of larger scale variation (e.g., global climate change).
Understanding the environmental parameters that constrain the distribution of a species at its latitudinal extremes is critical for predicting how ecosystems react to climate change. Our first aim was to predict the variation in the amphipod populations of Echinogammarus marinus from the southernmost limit of its distribution under global warming scenarios. Our second aim was to test whether sex-ratio fluctuations – a mechanism frequently displayed by amphipods – respond to the variations in populations under altered climate conditions. To achieve these aims, scenarios were run with a validated model of E. marinus populations. Simulations were divided into: phase I — simulation of the effect of climate change on amphipod populations, and phase II — simulation of the effect of climate change on populations with male and female proportions. In both phases, temperature (T), salinity (S) and temperature and salinity (T–S) were tested.
Results showed that E. marinus populations are highly sensitive to increases in temperature (> 2 °C), which has adverse effects on amphipod recruitment and growth. Results from the climate change scenarios coupled with the sex-ratio fluctuations depended largely on the degree of female bias within population. Temperature increase of 2 °C had less impact on female-biased populations, particularly when conjugated with increases in salinity. Male-biased populations were highly sensitive to any variation in temperature and/or salinity; these populations exhibited a long-term decline in density. Simulations in which temperature increased more than 4 °C led to a continuous decline in the E. marinus population. According to this work, E. marinus populations at their southernmost limit are vulnerable to global warming. We anticipate that in Europe, temperature increases of 2 °C will incite a withdrawal of the population of 5°N from the amphipod species located at southernmost geographical borders. This effect is discussed in relation to the distribution of E. marinus along the Atlantic coast.
Small-spatial scale changes in productivity of suprabenthic and infaunal crustaceans at the continental shelf of Ebro Delta (western Mediterranean)
2009, Journal of Experimental Marine Biology and Ecology
Production (P) and production/biomass ratio (P/B) were estimated from 21 species of peracarid and eucarid crustaceans belonging to two different compartments (infauna: 10 species and suprabenthos: 11 species) using the Hynes size–frequency method. Calculations were based on 7 cruises performed between December 2002 and November 2003 in the continental shelf of the Ebro river delta (ED, Catalan Sea: northwestern Mediterranean). Within ED, P and P/B were compared between two neighbouring sites, one located on 47 m (S1), the other at 61 m (S2). The possible effects of natural variability on production were considered. Sediments in ED were muddy (%clay between 40 and 65%). No significant trend in production comparing S1 and S2 was detected, with 50% of species showing higher P value in S1, and 50% in S2. A significant trend emerged from P/B estimates, with 18 of 21 species showing higher P/B at S1. Similarly significant trends for infauna and suprabenthos were found after analyzing both compartments separately. It is suggested that the more significant P/B found on S1 both among infauna and suprabenthos could be caused by the higher temperature and organic matter content (%TOC) at S1. In multi-linear regression (MLR) models, differences in P between S1 and S2 were greater with increasing differences in the density of species (RD) between sites. Differences were greater in infauna than in suprabenthos, and greater among rare species (those with low dominance, %D). P/B differences between S1 and S2 were mainly explained by %D and RD, and to a lesser extent by differences between sites in the mean size of species (RW). In other words changes in P and P/B were not explained by removal of large size specimens. Some trawling activity occurred at S2, and it may alter the habitat of small macrofauna. In addition to natural variability, we discussed the possible influence of trawling disturbance on P and P/B, bearing in mind the feeding type, mobility, and dispersal capability of species. We suggest that amphipods of the genus Ampelisca, showing higher P/B on S1, characterized by low mobility (probably tube-dwellers), low trophic level (e.g. filter feeding strategies) and low dispersal capability (not free larvae), could be especially vulnerable to trawling impact.
Reproductive bionomics and life history traits of three gammaridean amphipods, Cymadusa filosa Savigny, Ampithoe laxipodus Appadoo and Myers and Mallacoota schellenbergi Ledoyer from the tropical Indian Ocean (Mauritius)
2004, Acta Oecologica
The reproductive bionomics and life history traits of two corophiid amphipods (Ampithoe laxipodus, Cymadusa filosa) and one melitid (Mallacoota schellenbergi) were studied in Mauritius (Indian Ocean) for the period March 1999 to February 2000. Results on the population structure, monthly size class variations, sex ratio, female reproductive states and fecundity are presented. The study demonstrates multivoltinism and continuous reproduction in the three species. Increase in number of juveniles was observed in warmer months for C. filosa and A. laxipodus. Sexual maturity was attained at smaller sizes in warmer months in the three species. Linear relationship on body length and number of eggs in brood pouch are presented. Size-independent analysis of egg number revealed a decrease in number of eggs in cooler months. Sex ratio is male skewed in M. schellenbergi and female skewed in C. filosa and A. laxipodus. Some of the plausible explanations for the reproductive strategies adopted by these three species in a tropical system are discussed.
Does the accumulation of trace metals in crustaceans affect their ecology - The amphipod example?
2004, Journal of Experimental Marine Biology and Ecology
Crustaceans, like all aquatic invertebrates, take up and accumulate metals from a wide range of sources and the trace metal concentrations within their tissues and bodies show great variability. Trace metal uptake in crustaceans occurs from the water and food, either of which may be affected by the physico-chemical properties of the sediment. Accumulated metal concentrations in amphipods are contrasted with those of other crustaceans and examples are given to show how external and internal factors affect bioaccumulation. One of the major pathways for the uptake of trace metals is from solution directly through permeable surfaces including the gills. Changes in salinity and oxygen tension can modify the uptake characteristics from solution particularly in the case of interstitial water within sediments. Infaunal amphipods have direct contact with the sediment and the bioavailabilities of trace metals depend on the strength of the metal binding which is determined by a combination of properties including grain size, organic content, the presence of metals such as lead and iron as well as other ambient environmental conditions. Metal concentrations within amphipod bodies reflect the bioavailabilities of trace metals in their habitat. Body size is one of the major factors contributing to individual variability in trace metal concentrations within species. For some amphipod species, there are differences in trace metal accumulation with gender, breeding and developmental stage. In amphipods, accumulated body metal concentrations are the best biomarkers for environmental metal availabilities. Metal accumulation affects the ecology of crustaceans as a consequence of the energy costs associated with excreting and/or detoxifying the incoming metals. If the costs are significant, then this may result in reduced growth and reproduction. The effects of accumulated metals on communities have yet to be determined. Accumulated metals in crustacean prey species may be transferred along the food chain, but biomagnification in fish appears unlikely. One of the main ecological challenges is the need to link molecular biomarkers with ecologically relevant life history characteristics including growth, survival, reproduction and recruitment.
The influence of temperature and salinity on the duration of embryonic development, fecundity and growth of the amphipod Echinogammarus marinus Leach (Gammaridae)
2003, Acta Oecologica
The effects of salinity and temperature on the duration of embryonic development, fecundity and growth of the amphipod Echinogammarus marinus Leach from the Mondego estuary (Portugal) were studied in laboratory experiments. Combinations of three temperatures (10, 15 and 20 °C) and four salinities (10, 15, 20 and 25 ‰) were used. The duration of embryonic development was 33 ± 0.7 d (mean ± S.E.) at 10 °C, 32 ± 0.5 d at 15 °C, and 17 ± 0.3 d at 20 °C. Analysis of variance demonstrated that the duration of E. marinus embryonic development, reared under different combinations of salinity and temperature, was significantly affected only by temperature (P < 0.001). A positive correlation between the number of newborn juveniles and the size of E. marinus females (as head length) was observed. The number of juveniles released per female was higher at 10 °C and lower at 20 °C. Analysis of variance showed that only temperature significantly affected the number of juveniles released per female (P < 0.001). Experimental data were used to calibrate the von Bertalanffy growth model. Results showed that growth was continuous throughout life under all laboratory conditions. Intrinsic growth rates were higher at 20 °C and lower at 10 °C. Analysis of covariance applied over the initial 90 d after hatching showed significant differences between growth rates of E. marinus under different salinity and temperature conditions. Extrapolation of laboratory data to the field scenario suggests that E. marinus in the Mondego estuary have a multivoltine life cycle.
