Mario J. F. Calvete is a researcher at the CQC (Coimbra Chemistry Centre). He received his PhD in Natural Sciences–Organic Chemistry in 2004, from Eberhard Karls University of Tuebingen, Germany. In 2010 he was appointed as Auxiliary Researcher at University of Coimbra. His current research interests are tetrapyrrolic macrocycle design and other heterocyclic ligands and their uses in homogeneous/heterogeneous catalysis and theranostics.
I am PhD in Economics - Knowledge and Innovation, MSc in Regional Economics and graduate in Economics. My main research interests are innovation systems, knowledge networks, regional development, public policy and resilience. I am also interested in the discussion of Economics as a science and the economic crisis.
I am broadly interested in the evolutionary ecology of plants. Resources available are limited and plants have to split them between distinct demanding functions, like reproduction and growth; and to respond to different selective pressures, like competition and environmental stress. The study of such functional and evolutionary trade-offs and their plasticity is the underlying thread of my research. Biological invasions are planetary experiments in which to study these trade-offs, and I am using them extensively in my current projects. During my career I've been working with a number of organisms:
-Congeneric annual Centaurea species (Centaurea solstitialis, C. calcitrapa and C. sulphurea) suggest that biogeographic comparisons of these species may provide quite novel insights into invasive ecology. All of these species are native to Europe and all of them have been introduced into North America. The first species is a highly noxious invasive species but not common in its native range. The second is common in Spain, but has not become invasive in the US after 200 years. The last species is not common in either range. We are finding interesting differences in traits among species and ranges that may help to understand invasions in general. Data indicates that reproductive barriers are arising between native and non-native ranges of some of these species, which suggests that reproductive isolation can occur at fastest rates than it was previously thought, and might have broad biogeographic implications for the understanding of allopatry and speciation processes.
-Two congeneric Acacia species (Acacia dealbata and A. longifolia). Both species are native from Australia and introduced in Portugal. I am studying reproductive biology and dispersal systems of both species to understand how do they interact with the Portuguese native networks of pollinators and dispersers.
-The masting dioecious tree Juniperus thurifera has to split resources between reproduction and growth in a harsh, high mountain, dry environment. In species with separate sexes (dioecious) females usually invest more resources than males in reproduction, resulting in different trade-offs between growth and reproduction for male and female plants. During my Ph.D. I studied gender biased ecological performance of males and females, and how experimentally modified resource availability affected each sex's pattern.
-The endangered endemic Silene diclinis, accounts only with 2500 wild individuals in a few, nearby populations in Eastern Spain. This species developed a mechanism (barochory or atelechory) by which seeds are dispersed immediatly below mother plants, making sure that all seeds reach a perfect site for germinating and growing but making it impossible for the species to colonize new areas and driving the species to extinction in an evolutionary dead end.
Ana Marta Gonçalves completed her MSc and PhD degrees in Ecology in University of Coimbra (Portugal) in 2006 and 2011, respectively. Presently is post-doctoral researcher at MARE-UC and CESAM-UA. Her research interests lie in the frontier between Ecology and Toxicology. Her research interests relates to the ecotoxicological assessment of the impact of environmental and man-induced changes in aquatic organisms from different trophic levels, applying biomarkers tools as indicators of stress and early warning signals to detect the presence of stressors in aquatic ecosystems. The impact of global changes (individually and combined) at the nutritive value of preys and predators, and the impact of different diets in the nutritious value, relating it with food availability and preferences are research topics that AMG devotes special interest. AMG focus also her research in the ecology and dynamics of plankton communities and long time series, relating it with global changes such as extreme weather events. Part of her time is also dedicated to Environmental Education issues which have yielded several collaborations in projects with primary / secondary schools and the publication of book chapters in education.
My main research interest is in using complex species-interactions networks to frame important conservation problems at the community level. Such trophic or mutualist networks offer an holistic view-point to evaluate the causes and consequences of disturbances, such as the impact of biological invasions or biodiversity-loss, on important ecosystem functions, particularly seed-dispersal and pollination. A second passion is uncovering the rules guiding island colonization and community assembling.
I am a plant ecologist. I focus my work mainly in fire ecology and plant evolution and I have conducted my studies in fire-prone Mediterranean ecosystems (specifically in the Mediterranean Basin). My work encompasses the study of important traits for plant persistence in fire-prone ecosystems. Specifically I study post-fire regeneration strategies (germination and resprout) and plant flammability traits.
Regeneration is a key process for the success of plant populations and understanding this process provide clear clues for ecology and evolution of the species, as well as for predicting the future of our species in a changing world. I also study the impact of fire on the genetic variability of these species.
The aim of my work is to help understanding the role of fire in shaping plant species (i.e., fire-related plant traits) and populations.
