- A combined DPSIR and SAF approach for the adaptive management of beach erosion in Monte Hermoso and Pehuen Co (Argentina)Publication . Semeoshenkova, Vera; Newton, Alice; Rojas, Mara; Cintia Piccolo, M.; Lujan Bustos, M.; Huamantinco Cisneros, M. Andrea; Berninsone, Leonardo G.Coastal areas experience multiple pressures from anthropogenic activities that negatively change the ecological and environmental status of beaches and impact human welfare. The focus of this paper is coastal erosion, an issue that is very relevant for Argentina, the second largest nation in Latin America with an extensive coastline of nearly 5000 km. Coastal erosion decreases the attractiveness of coastal areas for tourism development, leading to considerable economic impacts. In this paper, two complementary approaches, the Driver-Pressure-State-Impact-Response (DPSIR) and the Systems Approach Framework (SAF), were used to analyse two beach resorts in Argentina: Monte Hermoso and Pehuen Co. Application of the SAF included stakeholder mapping, governance (institutional) mapping and issue identification. During the participatory meetings with stakeholders and decision makers, the problem of coastal erosion was identified as the most important in the region. The joint approach of DPSIR and SAF contributed to: (i) the determination and description of the economic drivers of coastal erosion; (ii) the identification of the associated activities and pressures; (iii) the assessment of the ecological and environmental state of coastal areas; (iv) the assessment of impacts of environmental changes on human wellbeing; and finally (v) a proposal of the possible management responses for mitigating the coastal erosion problem and the sustainable development of the region to the responsible authorities.

- Tagging, ranging patterns, and behavior of franciscana dolphins ( Pontoporia blainvillei ) off Argentina and Brazil: Considerations for conservationPublication . Wells, Randall S.; Cremer, Marta J.; Berninsone, Leonardo G.; Albareda, Diego; Wilkinson, Krystan A.; Stamper, M. Andrew; Paitach, Renan L.; Bordino, PabloThe franciscana dolphin, Pontoporia blainvillei, is one of the most threatened cetaceans in the Southwestern Atlantic. Within their limited coastal range off Argentina, Uruguay, and Brazil, franciscanas face human activities, including artisanal gillnet fishing and coastal development. A lack of information on ranging patterns, population structure, and behavior for informing management led to efforts to develop and apply approaches to tag franciscanas in Argentina (Bahía Samborombon [BS], Bahía San Blas [BSB]) and Brazil (Baía Babitonga [BB]) during 2005–2013. Findingsfrom VHF tags deployed in BS in 2005 during feasibility tests for catching and handling franciscanas for tagging suggested residency over periods of weeks. Subsequently, satellite-linked tags confirmed patterns of residency at each site. Home range size varied, with ranges of 5–7 km2 for BB, 51–312 km2 for BS, and 49–1,014 km2 for BSB. Diving patterns varied across sites, with the animals using the entire water column, exposing them to fishing nets regardless of the depth at which the nets were set. Tracking durations and follow-up observations indicated that this research approach is useful for studies of franciscanas. Small, definable ranges facilitate relating specific geographically based threats to appropriate population units, increasing the potential for effective conservation.
