Tidal action and macroalgal photosynthetic activity prevent coastal acidification in an eutrophic system within a semi-desert region

Nutrient input drive macroalgal blooms and increases in photosynthetic activity in coastal ecosystems. An intense macroalgal photosynthetic activity can increase the surrounding pH and it could prevent the acidification that often follows an eutrophication process. We tested this hypothesis with field sampling and experiments in a macrotidal (up to 9 m in amplitude) coastal system within a semi-desert region with contrasting eutrophic conditions and Ulva lactuca blooms in the northern Argentinean Patagonia (San Antonio Bay). Our results indicate that daily pH variability during low tide could be controlled by the photosynthetic activity of Ulva lactuca under eutrophic conditions. At seasonal scale, the pH variations were related to environmental features, particularly seawater temperature. Both environmental (i.e. high solar radiation, negligible freshwater inputs and large tidal action) and anthropogenic nutrient inputs into the studied area promote the Ulva lactuca blooms, which in turn increases the surrounding pH in well oxygenated seawater through the intense photosynthetic activity. Our study shows that eutrophication instead of being a driver of acidification, could contribute to its prevention in well oxygenated marine coastal systems located within semi-desert regions.Fil: Becherucci, Maria Eugenia.

Eutrophication and macroalgal blooms in temperate and tropical coastal waters: Nutrient enrichment experiments with Ulva spp.

Receiving coastal waters and estuaries are among the most nutrient-enriched environments on earth, and one of the symptoms of the resulting eutrophication is the proliferation of opportunistic, fast-growing marine seaweeds. Here, we used a widespread macroalga often involved in blooms, Ulva spp., to investigate how supply of nitrogen (N) and phosphorus (P), the two main potential growth-limiting nutrients, influence macroalgal growth in temperate and tropical coastal waters ranging from low- to high-nutrient supplies. We carried out N and P enrichment field experiments on Ulva spp. in seven coastal systems, with one of these systems represented by three different subestuaries, for a total of nine sites. We showed that rate of growth of Ulva spp. was directly correlated to annual dissolved inorganic nitrogen (DIN) concentrations, where growth increased with increasing DIN concentration. Internal N pools of macroalgal fronds were also linked to increased DIN supply, and algal growth rates were tightly coupled to these internal N pools. The increases in DIN appeared to be related to greater inputs of wastewater to these coastal waters as indicated by high δ15N signatures of the algae as DIN increased. N and P enrichment experiments showed that rate of macroalgal growth was controlled by supply of DIN where ambient DIN concentrations were low, and by P where DIN concentrations were higher, regardless of latitude or geographic setting. These results suggest that understanding the basis for macroalgal blooms, and management of these harmful phenomena, will require information as to nutrient sources, and actions to reduce supply of N and P in coastal waters concerned.Fil: Teichberg, Mirta.

Eutrophication in a semi-desert coastal ecosystem promotes increases in N and C isotopic signatures and changes in primary sources

Using C and N isotopic signatures of food web components, we evaluated the land-marine coupling through nutrient flows and the likely changes in the food web structure in tidal channels with contrasting anthropogenic nutrient inputs at a semi desert-macrotidal coastal system (northern Argentine Patagonia). The results showed an increase in the δ 13 C signatures of primary producers and in the δ 15 N signatures in all levels of the benthic food web, from primary producers to predators, with possible changes in the relative contribution of primary food sources for consumer in the tidal channel with high anthropogenic N input. This is an example on the extent of the distribution of anthropogenic N into natural systems, flowing through the food web from terrestrial origin to coastal marine components.Fil: Becherucci, Maria Eugenia.

Similar effects on sediment structure and infaunal community of two competitive intertidal soft-bottom burrowing crab species

The intertidal crabs Neohelice granulata and Cyrtograpsus angulatus are common on the south-west Atlantic coast but they rarely share the same microhabitat. They are similar in size and in several life history traits which promote competition. Neohelice granulata is the dominant species in intertidal soft-sediment and salt-marsh areas from southern Brazil to northern Patagonia Argentina, where it forms extensive burrowing beds. Its burrowing activity affects sediment characteristics as well as the infaunal community. When both species coexist N. granulata constrains the distribution and modifies some population characteristics and burrowing behaviour of C. angulatus. However, C. angulatus live in burrows forming dense burrowing beds in soft-bottom intertidal areas where N. granulata is absent. Where both species coexist, C. angulatus rarely constructs burrows and N. granulata clearly dominate soft-sediment areas forming conspicuous burrowing beds. This suggests that these crab species could have similar ecological roles in some effects on sediments related to burrowing activities. In this study, we experimentally compare their effects on sediment characteristics and infaunal community. The results of the experiment showed that C. angulatus modify sediment water and organic matter contents and grain size-frequency distributions similarly to N. granulata. Neither N. granulata nor C. angulatus affected the mean abundance of infaunal organisms during the experiment but their variances showed the same patterns in many cases, indicating similar effects. These results indicate that C. angulatus can modify sediment characteristics similarly to N. granulata, and has similar interactions with infaunal species.Fil: Martinetto, Paulina Maria del Rosario.

Negative interactions between two SW Atlantic intertidal crabs in soft-bottom habitats

The intertidal crabs Chasmagnathus granulatus and Cyrtograpsus angulatus coexists across the SW Atlantic intertidal. Previous studies in this region suggest that C. granulatus displace C. angulatus in soft sediment where C. granulatus build burrows (“burrowing beds”). We examine variation in abundance,  size frequency distribution, sex ratio, incidence of autotomies, and diet of both species in C. granulatus crab beds and adjacent areas without burrows. We also experimentally tested the hypothesis that in absence of C. granulatus, C. angulatus will build burrows. Only large sized individuals of C. angulatus venture into C. granulatus crab beds. The sex ratio of C. angulatus was always biased towards females, with higher bias outside crab beds (1:8 outside, 1:2 inside). Although the items consumed in the crab beds did not differed from those consumed outside, the males of C. angulatus had a higher frequency of empty stomachs in crab beds. The incidence of limb autotomies of C. angulatus was higher outside C. granulatus crab bed areas. After a long rainy period in which C. granulatus was absent from these areas, the pattern of habitat use of C. angulatus changed. During this period C. angulatus had higher abundance in the areas, where C. granulatus previously constructed burrows, and there were no differences between areas in any of the measured parameters. In the absence of C. granulatus, C. angulatus built their own burrows and never used C. granulatus burrows. The interaction between C. granulatus and C. angulatus may be a good example of competitive exclusion when the shared resource is the access to surface soft-sediment.Fil: Martinetto, Paulina Maria del Rosario.

Isotopic studies in Pacific Panama mangrove estuaries reveal lack of effect of watershed deforestation on food webs

Stable isotopic N, C, and S in food webs of 8 mangrove estuaries on the Pacific coast of Panama were measured to 1) determine whether the degree of deforestation of tropical forests on the contributing watersheds was detectable within the estuarine food web, and 2) define external sources of the food webs within the mangrove estuaries. Even though terrestrial rain forest cover on the contributing watersheds differed between 23 and 92%, the effect of deforestation was not detectable on stable isotopic values in food webs present at the mouth of the receiving estuaries. We used stable isotopic measures to identify producers or organic sources that supported the estuarine food web. N isotopic values of consumers spanned a broad range, from about 2.7 to 12.3‰. Mean δ15N of primary producers and organic matter varied from 3.3 for macroalgae to 4.7‰ for suspended particulate matter and large particulate matter. The δ13C consumer data varied between-26 and-9‰, but isotopic values of the major apparent producers or organic matter sampled could not account for this range variability. The structure of the food web was clarified when we added literature isotopic values of microphytobenthos and coralline algae, suggesting that these, or other producers with similar isotopic signature, may be part of the food webs.Fil: Viana, Inés G..

Distribution and structure of Conocarpus erectus L. (Combretaceae) in the northern limit of the Pacific Ocean (Gulf of California)

The distribution of species can expand or retreat following environmental changes. Climate change is driving changes in the distribution of several species. Changes in mangrove distributions have been reported subsequent to an increase in temperature following a tropicalization process. This study documents the presence of Conocarpus erectus above the reported northern limit for the Gulf of California (GC), updating its distribution limit in the Neotropic. The current northern distribution limit of C. erectus in the Pacific Ocean was found at Huatabampo, Sonora (26.69° N, −109.58° W) and San Jose Island, Baja California Sur (25.04° N, −110.63° W), which is different from previous estimates (1970: 23.23° N, −106.32° W; 2011: 23.31° N, −110.17° W). According to the model of the Center for Scientific Research and Higher Education of Ensenada (CICESE), the C. erectus seeds could be potentially dispersed as far north as Tiburon Island, Sonora. The sea surface temperature (SST) tended to increase more than >0.02 °C, which means an important increment on a decadal scale in the GC's SST. The temperature databases (atmospheric and SST) corroborated a temperature increase in this region since the 1980s. The expansion of C. erectus from its northern distribution limit supports the tropicalization process occurring in the GC. The current distribution and dominance of mangrove species in the GC could be changing due to oceanographic (e.g., El Niño-Southern Oscillation) and coastal (e.g., temperature and precipitation) changes. These types of changes have been reported previously in this region and for other mangrove distributional limits. These changes in mangrove distribution are expected to be accompanied by changes in the biota as well as in the provision of ecosystem services. Further and more specific studies are necessary to corroborate the changes in the distribution and the dominance/coverage of other mangrove species. The potential expansion of C. erectus could provide unique ecosystem services in arid and semiarid regions.Fil: Ochoa Gómez, Jonathan G.. Universidad Autonoma del Carmen; México.

Global Change Effects on Biological Interactions: Nutrient Inputs, Invasive Species, and Multiple Drivers Shape Marine Patagonian Communities

This book provides an integrated view of Atlantic coastal Patagonian ecosystems, including the physical environment, biodiversity and the main ecological processes, together with their derived ecosystem services and anthropogenic impacts. It focuses on the key components of the aquatic ecosystem, covering the lower levels (plankton) to the top predators like large mammals and birds, before turning to human beings as consumers and shapers of coastal marine resources. The book then presents an overview of how organisms that constitute the aquatic food webs have changed through time and how they likely will soon change due to global change processes and anthropogenic pressures. In this regard it offers a wealth of information such as long-term patterns in physical / atmospheric processes, biodiversity and the distribution of marine organisms, as well as the results of experimental studies designed to understand their responses under future scenarios shaped by both climate change and anthropogenic pressures. The book also covers various aspects of the past, present and potential future relationship of human beings with Patagonian coastal environments, including the utilization of sea products, tourism, and growth of cities.Fil: Valiñas, Macarena Soledad.

Role of marine macroalgae in the coastal pH regulation under global change sceneries

El aumento de CO2 antropogénico en la atmósfera está provocando un descenso del pH en los océanos a escala mundial. Este proceso de acidificación tiene consecuencias perjudiciales en diversos organismos, sobre todo calcificadores. Muchas de estas especies habitan las costas y por ello los estudios de acidificación se volvieron importantes en dichos sistemas. Sin embargo, estas áreas presentan variaciones de pH hasta 20 veces mayores que las cuencas oceánicas. Esto se debe a que en las áreas costeras los cambios de pH se producen por la acción de múltiples factores entre los cuales se destaca el metabolismo predominante del ecosistema. En los ecosistemas autotróficos existe un aumento del pH, el cual, a su vez, está controlado por el aporte de nutrientes. Entonces ¿cuál es el balance del pH en ambientes marino-costeros con predominio de macroalgas bajo escenarios de cambio global como la eutrofización?Fil: Becherucci, Maria Eugenia.
