Evaluación morfométrica y genética de la estructura poblacional de Cynoscion guatucupa de la costa de Buenos Aires en el Mar Argentino

This study analyzed the morphometric, microsatellite loci and mitochondrial control region variation of the striped weakfish from two feeding and spawning grounds in the coastal area of Buenos Aires province. The characterization of the body shape proved to be different between sites. Genetic structure analysis showed that the main source of genetic variation was within populations rather than among populations and low genetic differentiation was observed between sites. The striped weakfish inhabiting the coastal areas of Buenos Aires would exhibit two management units in agreement with other fishes studied in both areas.Fil: Sabadin, David Ezequiel.

Genetic Evidence of Expansion by Passive Transport of Aedes (Stegomyia) aegypti in Eastern Argentina

Aedes (Stegomyia) aegypti (Linnaeus) (Diptera: Culicidae) is the principal vector of the yellow fever virus, the five dengue virus serotypes (DENV-1 to DENV-5), chikungunya virus, Zika virus, and several types of encephalitis [1–3]. The behavior of this species is synanthropic and anthropophilic, being the culicid most closely associated with human populations [4]. The incidence of dengue has increased 30-fold over the last 50 years; according to the World Health Organization, up to 50–100 million infections occur each year in over 100 endemic countries, and at least one half of the world’s population has risk of being infected with dengue virus [5]. Chikungunya virus has been responsible for over 2 million human infections during the past decade and is currently moving to subtropical latitudes as well as to the western hemisphere. Up until April 2015, there have been 1,379,788 suspected cases of this disease in the Caribbean islands, Latin America, and the United States. This expansion into novel habitats brings unique risks associated with further spread of the virus and the disease it causes [6]. On the other hand, there are about 200,000 cases of yellow fever each year worldwide responsible for about 30,000 deaths, most of them from Africa. Zika virus is an emerging mosquito-borne virus, with outbreaks in Africa, Asia, and the Pacific between 2007 and 2014. Since 2015, there has been an increase in reports of ZIKV infection in the Americas, with Brazil being the most affected country, with 534 confirmed cases and 72,062 suspected cases between 2015 and 2016 [7]. All these viruses and the mosquito vector A. aegypti present in the Americas represent a serious risk. So far, in 2016, 39,926 dengue cases produced by DENV-1 and DENV-4 serotypes and 319 autochthonous cases of chikungunya fever have been reported in Argentina. According to the last census, Argentina has approximately 40 million people (National Institute of Statistics and Censuses of Argentina [INDEC], Census 2010), and over 38 million live in areas suitable for the transmission of dengue and chikungunya viruses [8]. Moreover, although there were 22 imported cases of Zika and 24 autochthonous cases confirmed in Argentina, there is a high incidence of cases in Brazil, and besides that, there is an internal circulation of the virus in the neighboring countries Brazil, Paraguay, and Bolivia [7,8], in addition to the constant expansion of the mosquito vector.Facultad de Ciencias Naturales y Muse

Genetic evidence of expansion by passive transport of Aedes (Stegomyia) aegypti in Eastern Argentina

Aedes (Stegomyia) aegypti (Linnaeus) (Diptera: Culicidae) is the principal vector of the Yellow Fever virus, the Dengue virus serotypes, Chikungunya virus and several types of Encephalitis. The behavior of this species is strictly synanthropic and anthropophilic, and it is the culicid most closely associated with human populations. In March 2011 and 2012 our group reported a new biogeographical record of A. aegypti in the southeast of Argentina. In order to determine the origin of the A. aegypti population?s distribution present in this new expansion area, we analyzed the mitochondrial lineages of these mosquito populations and compared their haplotypes with the haplotypes previously determined by Albrieu Llinás and Gardenal (2012) in Argentina and neighboring countries. The sampling stations were cemeteries and used tires located in towns next to the Provincial Route No 2 and in Buenos Aires city, La Plata (both at 400 km north from Mar del Plata) and San Clemente del Tuyú, a small town located on the Atlantic coast at 328 km south from Buenos Aires city, where this mosquito species was found for the first time. A 450 bp fragment of the ND5 gene was amplified by the polymerase chain reaction from a DNA extraction of each single larva. DNA sequences were identified and the haplotype frequencies for each population were calculated. In this work we report the presence of only two haplotypes in the new distribution area. H1 haplotype was detected in all localities analyzed, while H2 was only in two localities. According to our results only passive migration through human transport may explain the observed patterns, demonstrating once again the urgent need to implement serious campaigns to control vector mosquitoes and consequently the development of responsible control campaigns of the mosquito-borne diseases.Fil: Díaz Nieto, Leonardo Martín.

Les données morphomé-triques et méristiques relatives au spécimen sont incluses dans la diagnose. La présence d’espèces d’origines tropicales est fréquente dans les eaux côtières du nord de l’Argentine, probablement due à un apport d’eau subtropicale à l’ouest du courant de Malvinas.Fil: Ruocco, Natalia Lorena.

Regenerative bioturbation by intertidal burrowing crabs modifies microphytobenthic composition and enhances primary production in SW Atlantic mudflats

In coastal systems, benthic microalgae are important primary producers that significantly contribute to global primary production. Microphytobenthic (MPB) community structure and the ecosystem functions that it mediates are modulated by biotic and abiotic factors. Through burrowing activity, different types of bioturbators can impact MPB in different ways. Through directed sampling and field experiments performed at the Mar Chiquita coastal lagoon (Argentina), we evaluated the effect of regenerative bioturbation (continuous digging and maintenance of burrows, with sediment transfer from depth to surface) by the intertidal burrowing crab Neohelice (Chasmagnatus) granulata on MPB. We compared sediment properties and MPB attributes between natural burrowed and non-burrowed areas. Moreover, we experimentally manipulated regenerative bioturbation to evaluate if MPB composition and primary production are altered by crab burrowing activity. Field sampling showed that MPB and sediment properties differed between natural burrowed and non-burrowed areas. Experimental results indicated that regenerative bioturbation by N. granulata increased sediment oxygen concentration at each measured depth and also changed MPB composition (due to the reduced total abundance of cyanobacteria), but nearly doubled primary production in comparison with plots without bioturbation. Thus, the net effects of regenerative bioturbation were positive for MPB productivity, reinforcing the idea that this kind of bioturbation is an important biological force that enhances primary production in intertidal systems.Fil: Giorgini, Micaela.

Southernmost occurrence of Syngnathus folletti on a temperate coastal lagoon of Argentina

We report the occurrence of a mature male Syngnathus folletti in the inlet channel of Mar Chiquita coastal lagoon (37°44′S 57°25′W, Buenos Aires, Argentina). This record constitutes the southernmost report for the species. Mar Chiquita coastal lagoon is characterized by mudflats surrounded by a large cord-grass area but not by grass beds which are seen to be a suitable habitat for S. folletti. Therefore, oceanic winds that allow warmer northern waters to approach the coast of Argentina could be the cause of the presence of the species.Fil: Bruno, Daniel Osvaldo.

Discriminating the effects of bioturbation and herbivory by the intertidal burrowing crab Neohelice granulata on microphytobenthic assemblages of SW Atlantic mudflats

In shallow soft-bottom intertidal systems, microphytobenthic assemblages (MPB) and macrofauna interact and play important roles in ecosystem functioning. Macrofauna can affect MPB through bioturbation or/and herbivory. Most bioturbators also exert herbivory pressure on MPB, hence the results of the interaction between benthic macrofauna and MPB is not easy to predict. In this study we performed a small scale field experiment in order to discriminate the effect of bioturbation and herbivory by the intertidal burrowing crab Neohelice granulata on MPB structure, and primary production in SW Atlantic mudflats. The implemented treatments allowed us to separate the effects of bioturbation from those of herbivory on MPB. Results showed that N. granulata, through bioturbation + herbivory did not affect MPB structure (i.e., biomass, abundance and composition); and crab bioturbation without herbivory also did not modify MPB structure. Nevertheless, crab bioturbation without herbivory almost doubled MPB primary production, compared to the values registered in the treatment without bioturbation and herbivory and the treatment with bioturbation + herbivory. Sediment properties were equally affected by bioturbation in the four treatments. Thus, our results shows that the only significant effect on MPB structure is due to crab bioturbation.Fil: Giorgini, Micaela. Consejo Nacional de Investigaciones Científicas y Técnicas.

Ocean-estuarine connection for ichthyoplankton through the inlet channel of a temperate choked coastal lagoon (Argentina)

We examined the fish larvae colonising pattern of the Mar Chiquita lagoon (Argentina).We hypothesised that in this microtidal lagoon, winds could regulate fish larvae dynamics. Ichthyoplankton samples were taken in marine waters, the surf zone and the estuary. Previous studies showed no reproduction by fishes with planktonic eggs inside the lagoon. However high abundance of eggs and larvae of Brevoortia aurea collected within the estuary also suggest possible spawning activity. Throughout the study period, the cumulated richness of fish larvae was slightly higher in the estuary. However, univariate analysis revealed a higher number of species per tow in marine waters than in the estuary. The lowest average values of fish density, number of species and diversity recorded in the surf zone suggest that this area is only used as a transient corridor between the sea and the lagoon. The canonical correspondence analysis (CCA) indicated that wind direction, tidal stage, temperature and rainfall contributed significantly to the fish larvae distribution patterns observed; being ?onshore wind? the most important variable affecting fishes. Our results show how winds, in addition to pushing seawater into the lagoon, contribute to larvae recruitment into this estuary. Finally, we discuss the role of small lagoons in the life-history of coastal fishes.Fil: Bruno, Daniel Osvaldo. Consejo Nacional de Investigaciones Científicas y Técnicas.
