New paper: How can academics contribute to biodiversity science?

3/11/2022

We have a new paper in Biotropica discussing the role academics plays to biodiversity science. "This effort stemmed from a symposium on this topic at the 2021 ATBC meeting and the lively discussions that followed. We consider some general principles that will help scientists engage in the most effective, ethically appropriate action to have long-term impacts and then present a set of general, practical suggestions of ways scientists can engage with broader systems to promote positive changes."

Congratulations Anaid & Nancia!

Congratulations to lab member Anaid for being awarded a Tinker Field Research grant from the Center of Latin American Studies at UC Berkeley to conduct a preliminary study on patterns of movement, foraging and habitat use of howler monkeys in Mexico for her PhD

Congratulations to lab affiliate Nancia for being awarded a research grant from the Primate Conservation Inc to investigate the factors influencing lemur responses to edge effects in Madagascar as part of her PhD research project. And welcome to Berkeley! Nancia is currently at UC Berkeley as a Visiting Student Researcher

Welcome Jade!

1/10/2022

We're happy to welcome Dr. Jadelys Tonos as a postdoc in the lab. she recently graduated from Rice University with a PhD in Ecology and Evolutionary Biology, investigating the drivers and consequences of animal foraging behavior on seed dispersal and plant community composition.

New paper: Individual-based frugivore-plant network

9/15/2021

We have a new paper in Oikos examining how space and variation between individual plants affect movement and visitation by frugivores foraging on individual fruiting plants.

New paper: Seed dispersal limitation in forest edge habitats

9/15/2021

We have a new paper in the Frontiers of Ecology and Evolution investigating how differences between frugivore communities at the forest edge and interior habitats of a diverse tropical rainforest relate to patterns of animal-mediated seed dispersal and early seedling recruitment.

Main findings:

Lemur communities across the forest edge-interior gradient in this system showed the highest species richness and variability in body sizes at intermediate distances; the community of birds showed the opposite pattern for species richness.
Three large-bodied frugivores, known to be effective dispersers of large seeds, tended to avoid the forest edge.
The forest edges received a lower rate of animal-mediated seed dispersal compared to the interior habitats.
The seeds that were actively dispersed by animals in forest edge habitats were smaller in size than seeds dispersed in the forest interior. This pattern was found despite a similarity in seed size of seasonally fruiting adult trees and shrubs between the two habitats.
Despite these differences in dispersal patterns, we did not observe any differences in the rates of seedling recruitment or seed-size distribution of successful recruit species.

New Paper: roles of forests & tree in poverty dynamics

8/23/2021

We have a new paper in the journal Forest Policy and Economics reviewing the links between forests / tree-based systems and poverty dynamics.

Highlights:

Evidence on four broad roles forests and tree-based systems play in household poverty dynamics reviewed
Forests and tree-based systems shape household poverty dynamics through the production of both goods and ecosystem services
The most commonly reported role is to maintain households at a steady level of wellbeing
Negative forest externalities can maintain or move households into poverty
Addressing gender disparities can contribute to long-term poverty reduction goals
