Principal investigator, lab leader
Professor of Ecology at Universidade Federal de Pelotas.
Jef is a Brazilian ecologist interested in the ecology, evolution and conservation of animal-plant interactions. He often uses network analyses and null models to investigate how interactions are organized and how they define community structure and functioning. Pollination and seed dispersal interactions are his main study systems.
In his free time, Jef likes practicing yoga, playing soccer and spending time in nature, especially birdwatching.
Current members
Postdocs
Andrés is investigating patterns and processes underlying intraspecific interactions among antswarm follower birds and on seed dispersal networks. In his free time, he will likely be found biking, reading or enjoying 'asado' and dark beer with friends and family (including Ziggy, at the right)
Graduate students
Marcos studies how climate change may impact the co-occurrence of key frugivores and plants in Southern Brazil. At his undegrad interactions among plants and flower-dwelling mites that use hummingbirds to move from flower to flower.
Bruna is investigating how fruit and seed traits related to frugivory seed dispersal vary across large scales. She is also helping to create a fruit and seed collection form South Brazil.
Undergraduate students
Alan is investigating how fruit and seed traits related to frugivory seed dispersal and helping our with the creation of a seed and fruit collection
Arthur is beginning to investigate frugivory interactions on a keystone plant species in S Brazil
Gabriel is beginning to use molecular tools to investigate frugivory interactions in Southern Brazil
Victor is helping to create a regional seed collection and is investigating seed dispersal by non-flying mammals.

Extra-lab students
Lis is a PhD student at UNESP. She investigates processes shaping hawkmoth-plant interactions under the primary supervision of Dr. Felipe Amorim.
Former students
Fernanda investigated which traits define keystone species in a seed dispersal network in Southern Brazil.
Ju investigated how individual traits in a plant population filter out the bird species that consume their seedse also loves birdwatching.
Master in Animal Biology - Lis investigated the role of evolutionary histories in shaping mutualistic hawkmoth-plant interactions. Her resuts are currently under review.
BSc in Biology - Andreza studied the structure of mutualistic hawkmoth-plant interactions and its drivers. Here results are published in Ecological Entomology
Master in Animal Biology. Maiara investigated individual specialization on seed dispersers in a plant population Her results are published in Oecologia and Journal of Ornithology. Maiara is currently a PhD student at UFMS.
