A new diatom species from a transitional environment (Arade river estuary, Port...
Gomes, Ana; Hamilton, Paul Brian; Solak, Cüneyt Nadir; Boski, Tomasz; Moura, Delminda; Ertorun, Nesil; Yedidağ, FerhanDue to the environmental complexity created by physical and chemical gradients, transitional biomes host a large biological diversity. There has been some effort to better understand the diversity of diatoms living in these transitional environments, although many diatom species remain undescribed from these habitats. Gathering this knowledge will significantly improve our ability to halt biodiversity loss due ...
Paleolandscape evolution along the coasts of the Baixo Alentejo (Portugal) duri...
Goy, J.L.; Roquero, E.; Zazo, C.; Moura, Delminda; Dabrio, C.J.; Boski, Tomasz; Martínez-Graña, A.; Lario, J.; Bardají, T.A detailed geomorphological mapping allowed to understand the complex relationships interplayed between local tectonics and sedimentation across the coastal area of the Baixo Alentejo (Portugal) all along the Quaternary. Different outcrops of coastal sediments between Sines and Vilanova de Milfontes permitted to reconstruct a general sequence of up to fifteen stair-cased marine terraces, while wide sequences of...
Characteristics of organic matter sources from Guadiana Estuary salt marsh sedi...
Kumar, Mukesh; Boski, Tomasz; González-Vila, Francisco J.; Jiménez-Morillo, Nicasio T.; González-Pérez, José A.Estuaries are dynamic interfaces between land, rivers and the ocean that play major roles in the global carbon cycle. These coastal wetlands store huge amounts of organic carbon (OC), commonly known as “blue carbon” and excellent places to study C cycling. The Guadiana river estuary is among the most important tidal salt marshes in the South - Iberian coastal margin. Here, a detailed organic geochemical study i...
Food web structure of three Mediterranean stream reaches along a gradient of an...
Sroczynska, Katarzyna; Williamson, Tanner; Claro, Marilia; Gonzalez-Perez, Jose Antonio; Range, Pedro; Boski, Tomasz; Chicharo, LuisAnthropogenic impact can alter food web structure through changes in species interactions. In this study, we explored the food web of three Mediterranean stream reaches (two seasonal and one permanent) along an anthropogenic impact gradient to test the hypothesis that increasing impact simplifies food webs. To test this, we applied the isotopic (δ13C and δ15N) niche concept to compare reaches using isotopic met...
Drought, fire and grazing precursors to large-scale pine forest decline
Connor, Simon; Araújo, João; Boski, Tomasz; Gomes, Ana; Gomes, Sandra D.; Leira, Manel; Freitas, Maria da Conceição; Andrade, CesarAim Temperate forests are currently facing multiple stresses due to climate change, biological invasions, habitat fragmentation and fire regime change. How these stressors interact with each other influences how, when and whether ecosystems recover, or whether they adapt or transition to a different ecological state. Because forest recovery or collapse may take longer than a human lifetime, predicting the outco...

Projections of maximum tidal inundation limits of estuaries and lagoons of the ...
Sampath, Dissanayake; Boski, Tomasz; Moura, Delminda; Veiga-Pires, C.In the present study, we adopted the Hybrid Estuarine Sedimentation Model to simulate the estuarine and lagoon evolution in the South Algarve region due to projected mean sea level rise (MSLR) and sediment deficit scenarios during the 21st century. Thus, we forecasted morphological evolution of six large and medium size estuaries (Guadiana Alcantarilha, Arade, Gilão, Quarteira River, Alvor and a coastal lagoon ...
Integrated coastal management in Latin America : the ever new world
Scherer, Marinez; Costa, Monica F.; Boski, Tomasz; Azeiteiro, Ulisses; Dias, João AlveirinhoThe advancement of Integrated Coastal Zone Management (ICZM) in Latin American countries may vary from established programs to experimental phase implementation and even inexistence. This creates an opportunity for the development of new ideas and experiments, especially in the quite long stretches of littoral where no occupation has yet been planned or consolidated. However there are localized issues that need...
