Abstract: Established non-native sea anemone populations can affect the native community through multiple mechanisms, including predation and competition. The conservation of invaded communities is therefore of great concern, and spatially explicit information is essential for the prevention or early detection of introductions. Here, we used ecological niche modeling to (1) predict areas with invasion risk of 3 successful widespread invasive sea anemone species ( Diadumene lineata , Exaiptasia diaphana , and Nematostella vectensis ) (2) determine the invasion stage of current non-native occurrences and (3) test the climatic match hypothesis of invasion success by assessing their environmental niche dynamics. Our results bring new insights to the invasion process of sea anemones, which is relevant considering the scarcity of monitoring efforts, the issues associated with their detection, and the potential ecological effects they generate on invaded communities. First, we provide potential distributions that could help to detect non-native populations early on. Second, we confirm a strong pattern of successful establishment. Finally, we demonstrate that the invasion success of these species has mainly occurred in areas with environmental conditions similar to those from their respective native ranges (i.e. climatic match, niche conservatism).

Abstract: Even though Glycymeris longior is a clam widely distributed in the SW Atlantic Ocean, little is known about its biology and life history. The present study assessed the periodicity of the internal growth increments of G. longior using thin shell sections. Each internal growth increment was composed of two alternating bands: a translucent band (light-coloured when viewed with transmitted light) and an opaque band (dark-coloured). Annual formation for each pair of bands was demonstrated. The formation of the annual growth increments was synchronous among in iduals. Growth was determined from live clams collected at El Sótano, Argentine Sea (age range = 29 to 69 years). According to the growth model, G. longior grows fast during the first 5 years of life and then growth becomes slower in later years in iduals reached 50% and 90% of maximum size at 5 and 13 years of age, respectively. High variability was found in shell height for the first 10 years: differences up to 5–7 mm among in iduals were registered for the first 2 years of age, and up to 11 mm between the ages of 3 and 9 years. The growth performance index phi-prime (φ′) and the index of growth performance ( P ) of G. longior were compared with those of other Glycymeris species. Our results indicate that G. longior is a slow-growing species with a long lifespan (maximum longevity = 69 years).

Abstract: Non-native species can have profound implications on the survival of native ones. This is especially true for some invasive crabs, such as the green crab Carcinus maenas, a native species to the Northern Hemisphere that has been introduced into southern Argentina, from where it could expand through Argentina, Chile, and the Antarctic Peninsula. Hence, there is interest in forecasting changes in C. maenas habitat suitability through time to predict if potential future invasions might occur. Here, by using a Species Distribution Model (SDM) approach, we estimated the habitat suitability for C. maenas along southern South America and the Antarctic Peninsula under two future climate-change scenarios. Our results reveal that under current conditions, habitat suitability for C. maenas along the Antarctic Peninsula is null and very restricted in Argentina and Chile. Habitat suitability along the Antarctic Peninsula remained null in the short-term (30 years) and long-term future (80 years), despite the climate-change scenario considered. Surprisingly, when considering future conditions, habitat suitability along the coast of Argentina and Chile decreased and became nil for some currently occupied locations. Thus, the SDM results suggest that climate change could have a negative effect on the habitat suitability of C. maenas leading to potential local extinctions.
