The disruption of seed dispersal networks: disentangling the effects of habitat loss and fragmentation

open access: yesOikos, EarlyView.
Seed dispersal by frugivores is a central process linking plant reproduction, animal foraging, population persistence, and ecosystem resilience. Currently, the spatial template sustaining these interactions is rapidly reconfigured by habitat loss and fragmentation promoted by human activity.

Diet of Didelphis albiventris Lund, 1840 (Didelphimorphia, Didelphidae) in two periurban areas in southern Brazil

open access: yesActa Scientiarum: Biological Sciences, 2014
Didelphis albiventris Lund, 1840 is one of the least known Brazilian marsupials with respect to its feeding habits. Since the white-eared opossum is omnivorous, it occupies several niches and may be found in urban areas as well as in forest fragments ...

Diet, phenology and body size shape nutrient release by songbirds

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Animals can dramatically alter ecosystem structure and function through the cycling and transport of nutrients in their waste. While birds are particularly capable of influencing nutrient cycles due to their high mobility, abundance, metabolism and functional diversity,

Fruit consumption by Colaptes campestris (Aves, Picidae) at Emas National Park, Brazil [PDF]

open access: yesBiotemas, 2007
Although woodpeckers are primarily insectivorous birds, some species feed on fruits and flowers occasionally or regularly. Most records of fruit consumption by Colaptes species have involved C. melanochloros; there have been few records of C. campestris.

Belowground effects of ground‐dwelling large herbivores in forest ecosystems

open access: yesJournal of Animal Ecology, EarlyView.
This study reviews how ground‐dwelling large herbivores affect forest soil and litter globally. Effects are context‐dependent, vary among species and forest types, and remain poorly studied in tropical forests, highlighting critical gaps in understanding nutrient cycling and ecosystem functioning.

From steps to home ranges: How habitat disturbance influences the movement drivers of an arboreal primate

open access: yesJournal of Animal Ecology, EarlyView.
Challenging the narrative about howler monkeys' high resilience to anthropogenic changes, our multiscale analysis reveals the costs of habitat disturbance to their movement ecology. We identify thermal limitations, reduced travel efficiency, and significant spatial saturation.

Frugivory and seed dispersal in the Galápagos: what is the state of the art? [PDF]

open access: yesIntegrative Zoology, 2011
AbstractThe Galápagos are considered a model oceanic archipelago, with unique flora and fauna currently threatened by alien invasive species. Seed dispersal is an important ecosystem function with consequences for plant population dynamics and vegetation structure.

Hidden Losses: Assessing the Risk of Coextinction Among Ectoparasitic Flies and Their Bat Host Species in Brazil

open access: yesAnimal Conservation, EarlyView.
The potential impact of bat species extinction on the number of their ectoparasitic fly species, based on interaction data for Brazil. As bat host species are removed over time, more connected species (green) would experience steeper declines and lead to greater ectoparasite losses when compared to a random extinction model (gray).

Frequency of arboreality is correlated with longer hand skeletons in Gorilla: Analysis of a new skeletal sample of Bwindi mountain gorillas

open access: yesJournal of Anatomy, EarlyView.
Variation in arboreality across gorilla populations is associated with systematic differences in manual digital lengths. Using a new dataset of linear metrics from the Bwindi mountain gorillas, we quantify metacarpal and phalangeal lengths in eastern and western gorilla populations across all five rays. Consistent with quantified behavioral differences,
