Life appeared on this planet around 3.5 billion years ago (bya), as unicellular organisms without nuclei. Current phylogenetic analysis divides life in three domains: Bacteria, Archaea and Eukarya. In order to understand evolutionary events in the past, it is crucial that phylogenetic information is correlated to the fossil record. Unfortunately, the vast majority of microbial diversit…
This project will bring together an international team working in two cognate areas, evolutionary biology and palaeoecology, to develop new methodologies to aid in understanding the response of shelled protozoans to environmental stress. The project will focus on testate amoebae, a major group of eukaryotes that play an important role in microbial food-webs and nutrient cycling, and have …
Testate (shelled) amoebae are some of the most conspicuous soil and freshwater protists. The second half of the twentieth century saw a strong development of ecology with the use of testate amoebae as bioindicators for different environmental pollutants and other man-made perturbations. Dedicated meetings (ISTA) were intermittent, and 23 years passed between ISTA-3 (1983, Aachen, Germany…
The present project seeks to characterize amoebozoan diversity in Brazil, integrating aspects of traditional protistology with cutting-edge molecular techniques. Amoebae will be isolated from freshwater and marine environments in order to capture diversity in a comprehensive manner. Collected organisms will be subjected to two main study strategies: 1) unculturable organisms will be photo…
The emergence of evolutionary novelties is a central question in evolutionary biology. A scarcity of molecular data and bioinformatic tools have historically impaired the study of the origin and evolution of novelties. Currently, with the advance of molecular biology and bioinformatics, several works have proposed the evolutionary processes that underlie origin and evolution of novelties.…
Testate amoebae are amoeboid eukaryotic microorganisms that build an outer shell (also called test). The testate amoeba of interest of this study belong to the group of Arcellinida in the Amoebozoa. These testate amoeba are easy to find in the environment and several species have been documented to be highly resistant to environmental stresses. Indeed, there is a gradient of occurrence of…
In a pilot project we found evidence of gene duplication of RAD51 recombinase in the transcriptome of the testate amoeba Cryptodifflugia operculata. RAD51 is part of the recombinases superfamily. Recombinases are proteins responsible for DNA repair by homology. This project aims to define the presence or absence of RAD51 duplications in the Cryptodifflugia operculata genome from DNA extra…
Despite the importance of parasites on ecosystem and also as good biological index, the parasites'diversity studies has been neglected over the time, resulting in an understimated diversity pattern. Thisproject is focused on the survey of parasites cestodes fauna from the stingray Rhinpotera bonasusMitchill, found at tropical zones from the eastern Atlantic and the western Atlantic. The p…
Cellular motility is present in several areas of biology, its study uses the amoebae as one of the main models. This project aims to analyze the movement of two species of testate amoebae of Arcellinida - Arcella intermedia, Cyclopyxis lobostoma. Factors such as shell morphology and its apertural, as well as the number and structure of the pseudopodia will be considered. These factors wil…

Shells (tests) are present in diverse eukaryotic lineages. Testate amoebae are a diverse polyphyletic group inside eukaryotes, comprising only shelled unicellular organisms. Despite the diverse field that studies testate amoebae we lack molecular information relating to testate amoebae's shell origin and evolution. Arcellinida is a monophyleic testate amoeba group inside Amoebozoa, a key …
Microbial growth is a complex process involving numerous metabolic reactions that result in cell division. Typical growth curves have 4 phases: lag, log, stationary and decline. Arcella intermedia doesn't seem to follow exactly this same pattern of growth. In vitro, cell growth is dependent on several factors, such as pH, temperature, osmolality, gas concentration, available surface subst…
The discovery of a toolkit of genes with specific meiotic functions has lead to investigations on the occurrence and evolution of sex in diverse eukaryotic lineages. Remarkably, this toolkit has enabled studying meiosis even among those lineages long considered to be asexual in their life cycles. The product of those genes, namely SPO11, DMC1, REC8, MSH4/MSH5, HOP1, HOP2, MND1, MER3 and o…
