Intrinsic and extrinsic drivers shape frugivore functional diversity within a tree population In sessile organisms like plants, interactions with strong fitness implications, such as seed dispersal, are influenced by individual traits and the surrounding environmental context. Recent studies ...

Our findings demonstrate that plant phenotypic traits and local environmental conditions distinctly influence multiple facets and dimensions of avian consumer alpha diversity.

Rainfall alters network structure, while fragmentation results in the breakdown of a mixed-species group of birds - Oecologia Understanding the influence of species interactions on community structure and biodiversity is a long-standing goal in ecology. While species interactions are predicted to be vulnerable to environment...

We found total dissolution of ant-following groups at sites with lower habitat suitability and networks were more speciose, cohesive, and well-connected in drier sites compared to wetter forests of Panama.

Frugivory and Seed Dispersal in Tropical Urban Areas: A Review The diversity of fruits and frugivorous species is especially high in tropical regions where frugivory and seed dispersal interactions are particularly critical for the structure and functioning of terrestrial communities. However, the increasing urbanization in...

Seasonality and morphological variation shape intraspecific seed dispersal networks in gopher tortoises Intraspecific variation within animal seed disperser populations can influence the structure and function of plant–animal networks, with important consequences for vegetation dynamics and consumer be...

We used an individual-based bipartite network approach to examine how morphological traits and seasonality shape seed dispersal interactions of gopher tortoises Gopherus polyphemus on Florida’s pine rockland ecosystem.

Temporal Dynamics of a Neotropical Plant-Hummingbird Interaction Network

Our results show the importance of considering the temporal dynamics of tropical community to advance the understanding of the processes defining species interactions

We described the spatiotemporal variation in the diet of the iconic Hooded Berryeater (Carpornis cucullata), an endemic cotinga from the Atlantic Forest in Brazil.

It feeds almost exclusively on fruits; several endemics.

This Hawaiian island's 'freakosystems' are a warning from the future Ecosystems which have never been seen before are being accidentally created by humans. They offer a stark look into the nature of tomorrow.

"For the last decade scientists have studied O'ahu as an 'amazing crystal ball' that offers a glimpse of the future of our planet" – Jef Vizentin-Bugoni

Matt Ponsford interviewed me and some colleagues for an ably written BBC piece on Hawaii's novel ecosystems. Enjoy

Congrats and good luck, Raquel!

After 3 years as a faculty at @ufpel.bsky.social, I'm now tenured! It's been challenging to manage lab, grants, outreach and teaching activities but I couldn't be happier by being close to family and many friends while working at my alma mater for the benefit of nature and society. A dream came true

@paisaje-lab.bsky.social So cool, JuanP! Sorry that I missed this data in your paper. Shortly after this paper was out, a researcher from Asia contacted mentioning several cases of likely effective SD by woodpeckers there too. Looks like it is widespread geographically and within Picidae

Frugivory by woodpeckers (Aves, Picidae): new records and insights into their roles as seed dispersers - Ornithology Research In this study, we report four novel instances of frugivory by woodpeckers, specifically the green-barred woodpecker (Colaptes melanochloros), campo flicker (Colaptes campestris) and white-spotted wood...

🤩Chamadas no ar! Lançamos nesta sexta-feira (29) duas novas chamadas públicas de apoio a jovens cientistas do Brasil. O investimento dos editais totaliza R$ 8,4 milhões, a serem utilizados tanto no pagamento de bolsas quanto no financiamento de pesquisas. 👇

Ladrones de pelo: algunos pájaros, como el herrerillo bicolor, no tienen reparo en posarse sobre un mamífero y arrancarle un buen mechón de pelo para incorporarlo a su nido.

Fantástico! Muito obrigado!
