Tomas Carlo - Effects of avian frugivory in the structure and resilience of plant communities

March 1, 2021

Associate Professor of Biology & Ecology at Penn State University, and associate researcher in the ecology department at the Museo de Historia Natural of the San Marcos National University in Lima, Peru

Birds are the quintessential frugivores (fruit-eaters) that mutualistically disperse the seeds of a myriad plant species that in turn help nourish them. In so doing, birds directly and indirectly influence important community and ecosystem-level processes with broad implications such as forest regeneration dynamics, carbon dynamics, and the expansion of niches. In this lecture I will discuss the factors influencing fruit choices, and the consequences of such behavioral patterns to tropical plant communities. Specifically, I will examine how morphological, physiological, and behavioral factors shape avian frugivory and seed dispersal on Neotropical landscapes that have been fragmented by deforestation. Our results show that generalist birds usually normally classified as "insectivores" are critical to trigger a speedy forest regeneration and the recovery of plant diversity on tropical landscapes that have been affected by human activities and habitat destruction.

Dr. Tomas Carlo is Associate Professor of Biology & Ecology at Penn State University, and associate researcher in the ecology department at the Museo de Historia Natural of the San Marcos National University in Lima, Peru. He is an evolutionary ecologist studying how processes of avian frugivory and seed dispersal shape communities and their resilience. He is native to Puerto Rico, where he started bird watching and nature photography as a child in the mid 80’s. He has conducted most of his work in Puerto Rico, but recently expanded his work to South America (Peru, Brazil, & Argentina) and the Dominican Republic. His main research encompasses studies of the influence of fruit resources on habitat quality for birds, the relationship between fruit preferences and seed dispersal services of birds, and more recently, on the effects of bird seed dispersal on the assembly of successional forests. He has pioneered the developed of stable-isotope marking for study if seed dispersal at large scales. Carlo has also studied the relationship between bird movements and landscape heterogeneity using models and experiments, and the effects of reductions and losses of seabird colonies to the high-order ecological interactions in the terrestrial ecosystem of Mona island. He serves in the editorial boards of Biotropica and Oecologia as Associate Editor and Handling Editor respectively.

Gabrielle Nevitt - Following the scent of avian olfaction

April 5, 2021

Professor in the Department of Neurobiology, Physiology, and Behavior at UC Davis

When John James Audubon proclaimed that birds lacked a sense of smell, the study of avian olfaction was doomed to suffer ridicule by ornithology text books for years to come. In recent years, ornithologists have renewed their interest into the sense of smell in birds leading to a new appreciation of their chemical ecology. The tubenosed seabirds (petrels and albatrosses) of the order Procellariiformes have among the most impressive olfactory abilities of any animal on earth. Species within this order spend most of their lives flying over the world’s oceans, returning to land each year or every other year, to breed and rear a single offspring. They tend to partner for life and show strong nest-site fidelity between breeding seasons. Much of my research career has focused on elucidating how procellariform species use olfaction to perform behaviors ranging from foraging and navigation to mate choice and individual recognition. My presentation will touch on some of our recent findings and hopefully convince you that olfaction is a rich field of study, and that questions related to sensory ecology are both important and applicable to scientific inquiry into the biology and conservation.

Dr. Gabrielle Nevitt is a leader in the field of vertebrate Chemical Ecology and has conducted pioneering research in the sense of smell in birds, focusing on procellariform seabirds. She graduated from Stanford University, received her PhD in Zoology from the University of Washington, and did postdoctoral training in the Department of Neurobiology and Behavior at Cornell University. She has been a professor in the Department of Neurobiology, Physiology and Behavior at UC Davis for 24 years. She lives with her family on a rural property with various birds including emus.
