About This Project

Spiders are abundant and very interesting invertebrates, but there is still much we don't know about their diversity and distribution, especially in North America where it is estimated that only 27% of arachnids have been studied. Our objetive is study Phidippus spiders in North American, under a taxonomic, ecological, and evolutionary approach to evaluate its center of origin, geographic delimitation and divergence rates with parametric biogeography methods.

What is the context of this research?

The spiders of the Salticidae family or also known as jumping spiders, are the family with the largest number of species, and the genus Phidippus has more than 60 species, and most of them are found in North America. These spiders are very charismatic due to their colors and size. This spiders have been studied in morphological and behavioral topics , and there is only one work on their phylogeny, but this was done based on their morphology. We know very well the biology and ecology of these spiders; however, we need to understand their evolutionary history, and for this, it is necessary to obtain dated phylogenies and combine parametric biogeography methods to estimate their center of origin, divergence rates, and phylogenetic diversity of the species in the North. America.

What is the significance of this project?

We know a lot about the ecology and biology of spiders; but, the patterns of distribution, evolution history, and diversification remain controversial. We need more work on comparative analysis of the evolution of spiders, using molecular phylogenies for a better understanding of the evolution of spiders.

We have two hypotheses; the first, species of the genus Phidippus are monophyletic, and their most recent common ancestor diverged after the Eocene in North America. The second is, Phidippus species diversified gradually since the Miocene.

What are the goals of the project?

To test our hypotheses, we first have to obtain a dated phylogeny; this phylogeny will be obtained with ultraconserved elements (UCEs) in North America, how and when was its diversification and radiation and what were its evolutionary and historical biogeographic processes that shaped its current distribution.

The DNA samples will be obtained from museum samples and collaborations with people around North America, we hope to be able to capture UCEs of the more than 60 species of Phidippus that are described in North America.

This project has a budget for the fieldwork; however, there is still an important activity to be carried out for which there is no budget. This activity is the visit to entomological collections in search of spiders of the genus Phidippus to be able to carry out the DNA extraction of species in the United States since the work will be on North America and sequencing the DNA extraction. It is planned to visit entomological collections in New York at the American museum of natural history and San Francisco at the California Academy of Science.

If it is not possible to visit museums or a shipment can be coordinated as a loan of the samples, the money will be used to travel to San Diego, California with Dr. Marshal Hedin to obtain the UCEs.

This project is great becuase the study organisms are charismatic, pretty jumping spiders! By the end of the project, we will know more about how they evolved, where their center of origin is and how they spread across northern America. This information will help us identify the areas that need to be conserved.

Project Timeline

This research is part of my Ph.D. studies, where expeditions will be made throughout México and parts of USA, and we also plan to participate in congress to present our findings, to visit museums for morphological revisions and obtain samples for the DNA extraction to capture de UCEs. All this has to be done in four years, which is what my Ph.D. program lasts for.

Luis Hernandez

I graduated from the Autonomous University of Baja California in 2016 with a BSc in Biology. Later, I started to study an MSc in ecosystem management in the same institution. I am currently studying a PhD in Centro de Investigación Científica y de Educación Superior de Ensenada.

My research topic focuses on the use of spiders as bioindicators, although I have also worked on issues of arachnid biodiversity and public health impact issues, especially in the area of science dissemination in the city where i was born, Ensenada, Baja California, Mexico.

Sara Ceccarelli

I am fascinated by all lifeforms, but have a soft spot for spiders, which is why they are my main model organisms for the research I carry out on evolution and biogeography, at CICESE in northwestern Mexico. I obtained my BSc in Zoology from the University of Reading, UK, and my PhD on ant-mimicking jumping spiders from James Cook Uni in Townsville, Australia. Currently, I am a researcher in charge of the terrestrial arthropod collection at CICESE's Conservation Biology Department.
