Early naturalists suggested that predation intensity increases toward the tropics, affecting fundamental ecological and evolutionary processes by latitude, but empirical support is still limited. Several studies have measured consumption rates across latitude at large scales, with variable results. Moreover, how affects prey community composition such geographic scales remains unknown. Using standardized experiments spanned 115° of 36 nearshore sites along both coasts Americas, we found...
We studied the life history, reproductive biology and spatial distribution of Tanais dulongii on an intertidal flat near Mar del Plata, Argentina. The animals were obtained by systematic sampling in three zones (high, mid low), from October 2008 to September 2009. population density was low during most spring summer, increased autumn reached its maximum values at end this season (35 000 individuals/m2); a second, but lower, peak occurred winter (15 individuals/m2). Male remained below 1000...
Harbours are important sites for the containment and dispersal of invasive species throughout world, so study life history traits is to understand success their invasion potential effects on habitat. In recent years several have been reported in Argentinian harbours; however, studies ecology these scarce. We studied population dynamics reproductive biology Monocorophium acherusicum Ericthonius punctatus, order update published information introduced amphipods Mar del Plata harbour. Both...
We studied the population dynamics and reproductive biology of Caprella dilatata equilibra in order to provide basis for understanding ecological role both species Mar del Plata Harbour. Caprellids organisms from fouling community were obtained by sampling harbour, monthly April 2014 March 2015. Mean density C. was homogeneous during most study period (ca. 50–200 ind/100 g) reached their maximum May 650 g), while did not show any differences 30 g). Juveniles highest densities May, ovigerous...
The aims of this study were to compare the richness and population traits exotic native peracarid species in two ports Southwestern Atlantic (Mar del Plata: MDP, Puerto Madryn: PMY), order discuss vulnerability these environments biological invasions, explore current status assemblages life history that could favour establishment ports. Five biofouling samples taken each season from 2016 2017. present showed dominants both but profound differences registered between environments: MDP port is...
Life history strategies are closely related to environmental conditions and biotic abiotic factors play a major role conditioning several traits as growth rates, sexual maturity, size morphometric differences. We compare body dimensions, relative patterns, of differentiation between populations Tanais dulongii (Audoin, 1826) that live in two contrasting habitats order determine if they differ life traits. Some 900 individuals were collected (150 males, 150 females juveniles from each site)...
AbstractTanais dulongii (Audouin, 1826) is a small benthic crustacean with separate sexes and marked sexual dimorphism characterized by cephalothorax narrowed anteriorly, larger chelae (claws) pair of tiny genital cones in males, ovisacs that form chambers for carrying embryos females. Recent studies have described the existence intersexual individuals similar to large ovisacs, but, due their size, it has not been possible confirm presence under normal light microscopy. The present study...
Abstract Life‐history traits of exotic species are important to understand the process involved in their settlement and potential impact on native biodiversity. In this context, seasonal density, population structure reproductive patterns peracarid two natural marine environments Southwestern Atlantic were studied order determine that favour invasion success species. Five samples, consisted algal patches (0.20 × 0.20 m quadrants), collected seasonally from 2016 2017 intertidal (La Estafeta...
We report the occurrence of invasive amphipod Monocorophium acherusicum in Mar del Plata port, Argentina, using morphological and molecular analysis estimated mean abundance to detect monthly variations this population. compared M. morphology with that insidiosum Crassicorophium bonelli, two most similar locally occurring species, establish diagnostic characteristics for correct identification them; moreover, we provide some taxonomic notes about others corophiids regionally distributed....
Abstract The present study reports for the first time association between decapod Thymops birsteini (Nephropidae) and amphipod Caprella ungulina (Caprellidae). A benthic biodiversity survey was carried out to explore Mar del Plata Submarine Canyon, off Argentine coast, in South-western Atlantic Ocean. total of 205 caprellids (181 juveniles, 4 males 20 not-classified individuals) were found attached 7 specimens T. caught 1087–2212 m depth. epibiotic parameters showed that prevalence C. on...
Ports are considered important sites for reception and dispersion of marine exotic species throughout the world, making monitoring studies necessary to determine vulnerability these areas those species.Peracarids characterized by larval stages restricted female brood pouch juveniles with a low dispersal rate.However, several have invaded large number environments worldwide, them an excellent model invasion studies.The main objective this work was study diversity peracarid in two ports...
