I'm parg Ph. My research focuses on the ecology and evolution of symbioses. I am particularly interested in how mutualistic interactions are structured at different spatial scales and along landscape gradients. I address these questions parrt cyanolichens as a model system and within a robust phylogenetic framework. I always enjoy engaging in conversations about my research or any related topics. I'm also committed to making all resources from my studies available to anyone interested.

The cyanobacterial symbionts that are found in the lichens that I study are from the genus Nostocin the order Nostocales. To study how symbiosis has evolved in these cyanobacteria, it is very important to have a good idea of their evolutionary history.

In trying to figure out the phylogenetic position Nostoc within Nostocales, I realized that previous phylogenomic studies of this order recover what is an ode differential equation relationships when using different datasets i.

What is the cause of these conflics? Because these are bacteria, my initial hypothesis was that these conflicts could be the result of widespread horizontal gene transfers HGTs. However, what does the circled part of the phylogenetic tree indicate findings indicate that an ancient radiation at the origin of some of the major lineages of Nostocales is the main cause of the phylogenetic conflicts. Stay tuned for the upcoming paper!

PCCRi: Rivularia sp. PCC, S: Scytonema sp. HK 05 v2, and T: Tolypothrix sp. NIES New approach to study phylogenetic specialization in ecological networks.

A species that interacts with two partners is often considered more specialized than a species that interacts with five. But what if the two partners of the first species are distantly related, and the five partners of the second species are closely related? How do we characterize indicahe then? I developed an approach that integrates phylogenetic structure and partner availability to detect three different patterns of specialization in ecological networks Fig 2.

Check out the wuat and oc R package for computing PSS! Fig 2.

The size of the orange circles represents the relative availability of each member of guild A in an interaction matrix. Our approach measures the Phylogenetic Structure of Specialization PSS to characterize these different types of specialization. Eco-evolutionary doe of cyanolichen network structure.

I am sequencing over cyanolichen specimens collected by the ABMI define symbiotic nutrition class 7 Alberta, Canada, to study the spatial structure of the interaction network between lichen-forming fungi from the genus Peltigera and their Nostoc cyanobionts. Preliminary results show that at least 28 species of Peltigera are found in Alberta Fig 3A. In contrast, only six Nostoc phylogroups are found in most thalli.

The distribution of these Nostoc phylogroups seems to be spatially structured Fig 2 B-G. My goal is to study the network properties at different spatial scales and within a robust macroevolutionary framework for both partners. Fig 3. Association patterns and spatial distribution of the six most common What does the circled part of the phylogenetic tree indicate phylogroups associated with Peltigera in Alberta based on thalli from 61 ABMI tred sites.

Indicatd circles in the columns show the Nostoc phylogroups found in association with each species. Roman numerals correspond to Nostoc phylogroups. Colored circles represent circlfd where the Nostoc phylogroups associated with Peltigera were found. The size of the colored circles denotes the number of thalli in which a Nostoc phylogroup was found at a given site. Phylogenetics and interaction patterns in the Peltigera-Nostoc symbioses. During my undergraduate research, I studied lineages of Peltigera that form trimembered thalli, i.

I found that two closely related lineages of Peltigera show contrasting patterns of specialization towards their cyanobacterial partners Fig 4. Species cicled section Chloropeltigera can associate with up to seven Nostoc phylogroups, while species from section Peltidea associate only with two. I also found evidence that this difference in association patterns might be driven by the type of photobiont transmission. In Peltideait is likely that most of the photobiont transmission is vertical, favoring specialization.

In Chloropeltigeraphotobiont transmission might be mostly horizontal, favoring acquisition of new partners through time. Fig 4. Phylogenetic relationships among the three Peltigera sections that include trimembered thalli. Bars on the right indicate the proportion of Peltigera specimens associating with Nostoc phylogroups, Coccomyxa species, and inhabiting various geographic regions.
