Flujos de detritos y dispersores de energía en la torrentera Juan Carossio Chosica - Lima

Revista del Instituto de Investigación de la Facultad de Ingeniería Geológica, Minera, Metalúrgica y Geográfica, 2014
La cuenca de la quebrada Juan Carossio tiene un ancho aproximado de 15 metros, con una longitud de 1,308.29 metros, lo que arroja una superficie colectora de alrededor de 2 km2. Está limitada en la parte alta por la cota 1,308.29 m s.n.m., y en la parte inferior con la entrega al río Rímac en cota 900 m s.n.m. Longitudinalmente, en la zona central alta

Trait‐mediated effects driven by an invasive herbivore alter functionally diverse plant–frugivore interactions

Functional Ecology, Volume 40, Issue 1, Page 216-228, January 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Fruit traits play a fundamental role in mediating plant‐frugivore interactions, shaping seed dispersal dynamics. Given the complexity of multi‐species interactions, these traits and, consequently, plant‐frugivore interactions can be indirectly influenced by third‐party ...

Remoción de frutos de una especie invasora (Lantana camara L.) en el Bosque Chaqueño de Córdoba (Argentina)

Ecología Austral, 2009
El proceso de remoción de semillas puede variar en función de la invasión de nuevas especies, de los grupos de animales involucrados en la interacción y del grado de fragmentación del ambiente. El objetivo del presente trabajo es describir y cuantificar

Dispersão de sementes de Melocactus glaucescens e M. paucispinus (Cactaceae), no Município de Morro do Chapéu, Chapada Diamantina - BA Dispersion of Melocactus glaucescens and M. paucispinus (Cactaceae) in the municipality of Morro do Chapéu, Chapada Diamantina - BA

Acta Botânica Brasílica, 2012
Objetivou-se identificar os dispersores de duas espécies de Melocactus, verificar o padrão de liberação dos frutos, correlacionando-o com a remoção por frugívoros e variação térmica do cefálio, bem como caracterizar a distribuição espacial.

Effects of manakin gut passage on germination of a neotropical melastome shrub (Melastomataceae)

Biotropica, Volume 57, Issue 1, January 2025.
In a paired germination experiment, we found that manakin gut passage accelerated germination of a common and widespread Melastome shrub, Miconia rubescens, which may function as an important pioneer in regenerating rainforest. Manakin species varied in their gut passage effects and within species, body mass correlated with greater and earlier ...

Genomic signatures of past megafrugivore‐mediated dispersal in Malagasy palms

Journal of Ecology, Volume 112, Issue 7, Page 1583-1598, July 2024.
Our results suggest that the legacy of megafrugivores regularly achieving long dispersal distances is still reflected in the population genetics of palms that were formerly dispersed by such animals. Furthermore, low genetic differentiation was possibly maintained after the megafauna extinctions through alternative dispersal (e.g.

Habitat differences in seed‐dispersing vertebrates indicate dispersal limitation in tropical bracken‐dominated deforested areas

Biotropica, Volume 56, Issue 3, May 2024.
Forest regeneration in tropical bracken‐dominated deforested areas is mainly hindered by dispersal limitation. We found differences in species composition of seed‐dispersing birds and bats between the forest and bracken‐dominated areas, which could be one of the main causes of dispersal limitation in forest regeneration in tropical bracken‐dominated ...
