Amazonian fish migration as a social–cultural–ecological process

open access: yesPeople and Nature, Volume 7, Issue 12, Page 3297-3312, December 2025.
Abstract In this study, we highlight the rich perspectives and explanations of fish migration held by Indigenous groups across the Amazon. We present the aspects of Indigenous cosmological stories, drawing from our exploratory review of cultural ethnographies and grey literature, as well as the authors' own experiences. We ask, how do Amazonian peoples

Distributional patterns of cecropia (Cecropiaceae): a panbiogeographic analysis

open access: yesCaldasia, 1997
A panbiogeographic analysis of the distributional patterns of 60 species of Cecropia was carried out. Based on the distributional ranges of 36 species, we found eight generalized tracks for Cecropia species.

Ecological function over evolutionary legacy: The limited role of shared evolutionary history in shaping modern frugivory interactions

open access: yesFunctional Ecology, Volume 39, Issue 12, Page 3688-3703, December 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Frugivory, encompassing interactions between vertebrates and plants that range from mutualistic to antagonistic, drives seed dispersal and underpins the structure and resilience of tropical ecosystems.

A New Species of Neotropical Carpenter Ant in the Genus Camponotus (Hymenoptera: Formicidae), Apparently without Major Workers

open access: yesPsyche: A Journal of Entomology, 2012
We describe a new species of carpenter ants from Ecuador, which apparently has an obligatory relationship with the ant plants Cecropia membranacea Trécul, C. herthae Diels and C. marginalis Cuatrec.

Using the U‐net convolutional network to map forest types and disturbance in the Atlantic rainforest with very high resolution images

open access: yesRemote Sensing in Ecology and Conservation, 2019
Mapping forest types and tree species at regional scales to provide information for ecologists and forest managers is a new challenge for the remote sensing community. Here, we assess the potential of a U‐net convolutional network, a recent deep learning

Interações biofísicas em espécies arbóreas potencialmente acumuladoras de fósforo: diversidade de irradiância e de comportamento hídrico Biophysic interaction in potentially accumulative phosphorus wood species: irradiance diversity and hydric behavior

open access: yesActa Amazonica, 2008
O entendimento das interações biofísicas entre espécies acumuladoras de fósforo, como Neea macrophylla e Cecropia palmata com a radiação e a água disponível em florestas secundárias no Nordeste Paraense torna-se fundamental para a composição de Sistemas ...

A re-evaluation of silk measurement by the cecropia caterpillar (Hyalophora cecropia) during cocoon construction reveals use of a silk odometer that is temporally regulated.

open access: yesPLoS ONE, 2020
The late 5th instar caterpillar of the cecropia silk moth (Hyalophora cecropia) spins a silken cocoon with a distinct, multilayered architecture. The cocoon construction program, first described by the seminal work of Van der Kloot and Williams, consists

Characterization of the complete chloroplast genome sequence of Cecropia pachystachya

open access: yesMitochondrial DNA. Part B. Resources, 2017
The complete chloroplast genome of Cecropia pachystachya Trécul was determined in this study. The total genome size was 153,925 bp in length, containing a pair of inverted repeats (IRs) of 25,443 bp, which were separated by large single copy (LSC) and ...
