I’m interested in the evolution of social behaviors, especially behavior associated with mating and care.
Every
biological trait is shaped by environment and genetic information.
However, to which extent genes and environment affect different
traits varies greatly in nature. In my current work I try to
characterize the
genetic and phylogenetic bases of traits involved in reproduction and
fitness. This includes morphological, life history and behavioral
traits. During my PhD I developed molecular markers for non-model
organisms that can assist in this process and I am collecting
genetic samples from different bird populations from all over the
world.
My favorite study organisms are small beach and wetland birds, the Charadrius
plovers. Plovers are found in many places all over the world and I
have studied plovers with collaborators in Turkey,
United Arab Emirates, Mexico, Peru, Puerto Rico and Australia. Plovers
are fascinating creatures. Some have remarkable variable breeding
systems that differ even between populations of the
same species. One of my current goals is to establish the
phylogeography for one of the most reproductively flexible species, the
Kentish plover superspecies complex. During, my PhD I found that the
American populations which are commonly called ‘snowy plover’ are
phenotypically and genetically distinct from Eurasian populations which
are called ‘Kentish plover’ and deserve to be considered as a full
species
on their own. Recognizing the snowy plover as a species in it's own
right will help the conservation of this threatened bird who is endemic
to the Americas.
The
different members of the Kentish plover superspecies complex have
colonized all continents except Antarctica. These
plovers have a very interesting family life that sheds light on the
evolution of parental cooperation and conflict. Some families are
attended
by both parents, but in many families one of the parents (usually the
female) abandons the brood and starts a new family with another male.
The desertion happens usually around the time of hatching of the
chicks. Whether parents cooperate for brood care or not depends on many
factors
which are still not fully understood. Using a phylogeography based
on multiple DNA markers I rey to find the origin of the species complex
and follow its colonization routes that have led to the present day
distribution. The map is going to be the base to investigate how
phenotypic traits such as
morphological characters, plumage and behavior associated with
reproductive behavior have evolved into their present forms and whether
certain lineages of plovers are more prone for
parental cooperation than others.
My
second interest involves the evolutionary genetics of breeding system
traits. Breeding systems comprise mating and care strategies within a
population. They harbor many traits that are sexually selected. This
work is conducted at Bahía de Ceuta in Sinaloa which harbors one of the
largest snowy plover breeding populations at the Pacific and intense
surveys of behaviour have been carried out since 2006. Every adult and
chick is marked with color and metal bands and together with local
students and collaborators we follow their fates over the breeding
season. Snowy plovers are sexually reversed, that means the females are
more emancipated than in most other species. In contrast to females,
males are often left to bring up the young alone and struggle to find
new partners. My goal is to identify social, environmentally and
particularly genetic factors that influence the breeding system traits
characteristic for sex role reversal. In this project we aim to combine
long-term field investigations of individually marked breeding snowy
plovers in Northwest Mexico with laboratory studies using multiple
genetic markers.
Snowy plover fieldwork is adventurous and often
very exciting. It is one of the rare occasions to experience incredible
wildlife and learn more about the life, behavior and challenges of wild
animals. If you want to get a flavour about our work in Mexico or the
amazing life of snowy plovers visit our website at www.chorlito.org. During the field season from April to July we frequently update the pages - it pays off to check frequently.
