Our Team

We are an enthusiastic group of researchers, teachers, fellows and students
focused on the reproductive biology of arthropods, with emphasis on the evolution of sexual traits
among the arachnids.

My research line is oriented to the study of the reproductive biology of arachnids and
other arthropods. In this context, I approach issues within the framework of sexual selection.

Camilo Mattoni

Camilo Mattoni

My research line concerns “Phylogeny, Comparative Morphology,
Reproductive Behavior, Evolution and Ecology of Scorpions: A Multidisciplinary Approach”.

David Vrech

I analyze sperm production in Scorpiones and Solifugae,
and assess the influence of sperm competition in shaping the evolution of certain
sperm characters in both, males and females.

My research line is titled “Sexual selection in spiders:
Behavioral patterns and influence of genitalia on reproductive success in Holocnemus
pluchei (Pholcidae)”.

Alejandra Ceballos

Alejandra Ceballos

Currently my line of research is oriented to the study ofx
sexual behavior of pseudoscorpions and how they affect the gregarinas (Apicomplexa) in their
sexual selection.

Matias Izquierdo

I graduated in 2008 in Biology at Facultad de Ciencias Exactas, Físicas y Naturales from the
Universidad Nacional de Córdoba (Argentina). From 2009 to 2014 I worked at Museo Argentino de Ciencias Naturales
“Bernardino Rivadavia” (Buenos Aires) where I developed my PhD on Biology with a fellow from CONICET (National
Scientific and Technical Research Council).

Paola Olivero

Paola Olivero

My research line is related to the study of the reproductive
biology of arachnids and insects, analyzing the courtship, reproductive behavior
and patterns of differential paternity, currently in the scorpion species Bothriurus bonariensis.

Franco Cargnelutti

Franco Cargnelutti

During my post-doctorate, I will try to discover
the effect of the contamination of the Suquía River on the reproductive
biology of riverbank spiders mediated by insects with aquatic stages.
I will cover this study from several aspects, among which are the behavioral,
physiological, and morphological ones.

Fedra Bollatti

My current research line is focused on
the study of alternative reproductive tactics in males of Allocosa senex,
a wolf spider with sex-role reversed.

Mariela Oviedo

Mariela Oviedo

I am currently studying evolutionary processes in populations of two
scorpion species (Urophonius) in scenarios of sympatry and allopatry, in a comparative approach
at interspecific and intraspecific level.

Débora Anael Abregú

Débora Anael Abregú

Currently my thesis focuses on the reproductive and morphological aspects of
Metaltella simoni under a context of sexual selection.

Diego M. Fink

Diego M. Fink

I’m qualified in the handling of instruments and materials for the
making of histological preparations.

Rocio Palen Pietri

Rocio Palen Pietri

I’m doing my Ph.D. on the reproductive biology of pseudoscorpions
to broaden the knowledge of this area, studying morphological aspects, sexual competition,
and reproductive behavior from a sexual selection perspective.

Catalina Simian

Catalina Simian

I am currently doing my PhD on the reproductive aspects of
two Solifugae species, Nothopuga sp. and Oltacola chacoensis, which have opposite
mating strategies, one having a markedly persuasive courtship and the other copulating
in a coercive manner.
