Towards Chl-a Bloom Understanding by EM-based Unsupervised Event Detection ArchiMer
Poisson Caillault, Emilie; Lefebvre, Alain.
Marine water quality monitoring and subsequent management require to know when a specific event like harmful algae bloom may occur and which environmental conditions and pressures lead to this event. So, event detection and its dynamic understanding are crucial to adapt strategy. An algorithm is proposed to identify curves mixture and their dynamics features - initiation, duration, peaks and ends of the event. The approach is fully unsupervised, it requires no tuning parameters and is based on Expectation Maximization process to estimate the most robust mixture according to fixed criteria. A complete framework is proposed to deal with a univariate time series with missing data. The approach is applied on Chlorophyll- a series collected weekly since 1989....

Resource Competition Affects Plankton Community Structure; Evidence from Trait-Based Modeling ArchiMer
Sourisseau, Marc; Le Guennec, Valerie; Le Gland, Guillaume; Plus, Martin; Chapelle, Annie.
Understanding the phenology of phytoplankton species is still a challenge and despite a lot of theoretical work on competition for ressources this process is under-represented in deterministic models. To study the main driver of the species selection, we thus used a trait-based model that keeps phenotypic variability through physiological trait parameterization. We next validate the results by using a key species, the toxic dinoflagellate Alexandrium minutum. Due to their monitoring, we show that harmful algae are ideal models for studying ecological niches and for contributing to this more global challenge. As a first step, a dimensionless model of an estuary (France) was built with water temperature and water exchanges deduced from a hydro-dynamic model....

Thermal requirements of citrus fruits grafted onto rootstocks in the low-middle region of the São Francisco river basin. Repositório Alice
NASCIMENTO, F. S. S.; RIBEIRO, V. G.; BASTOS, D. C.; SÁ, J. F. de; NASCIMENTO, P. H. D..
To understand the production cycle of a particular cultivar in a given region, it is necessary to obtain information related to its phenology and the accumulated degree days. The purpose of this study was to evaluate the phenological cycle of citrus species grafted onto two rootstocks and grown in the Low-Middle Region of the São Francisco River Basin, in particular with respect to accumulated degree days. The experiment was conducted using ?Rubi? and ?Pera D-12? oranges and ?Page? mandarins. Two rootstocks were used, namely ?Cravo? and ?Volkameriano? lemon species that were drip irrigated in the Campo Experimental de Bebedouro, an experimental field owned by Embrapa Semiárido. ?Page? mandarins with ?Cravo? or ?Volkameriano? rootstocks exhibited a...

Pollen dispersal and deposition in an agroecosystem at Province of Buenos Aires, Argentina Darwiniana
Madanes,Nora; Fernández,Celina A.
The aim of this study is to analyze factors and mechanisms involved in dispersal and deposition of airborne pollen captured with Tauber type traps in a 20 x 20 m plot of Helianthus annus cultivation and accompanying weeds and to investigate the relation of these processes with the vegetation structure and dynamics from cultivation to its senescence over a 14 week period. Weekly samples obtained with pollen traps showed a significant change in the deposition due to a filter effect and dispersal patterns due to source variations during the time elapsed. A conceptual and interpretative model for both processes and its relation to pollen sources is proposed. Our results showed that in the study site, the leaves development of Helianthus annus produced a pollen...

Assessing the sensitivity of bivalve populations to global warming using an individual-based modelling approach ArchiMer
Thomas, Yoann; Bacher, Cedric.
Climate change exposes benthic species populations in coastal ecosystems to a combination of different stressors (e.g. warming, acidification and eutrophication), threatening the sustainability of the ecological functions they provide. Thermal stress appears to be one of the strongest drivers impacting marine ecosystems, acting across a wide range of scales, from individual metabolic performances to geographic distribution of populations. Accounting for and integrating the response of species functional traits to thermal stress is therefore a necessary step in predicting how populations will respond to the warming expected in coming decades. Here, we developed an individual‐based population model using a mechanistic formulation of metabolic processes...
