Impacts of fire on canopy structure and its resilience depend on successional stage in Amazonian secondary forests

Remote Sensing in Ecology and Conservation, EarlyView.
We analyzed the effects of fire on secondary forests' vertical structure in different successional stages using lidar metrics. Our results show that independently of the successional stage, secondary forests that experienced fire were more degraded than unburned secondary forest areas. Overall, our results show that forests in early successional stage (

A regional model for estimating the aboveground carbon density of Borneo's tropical forests from airborne laser scanning [PDF]

arXiv, 2017
Borneo contains some of the world's most biodiverse and carbon dense tropical forest, but this 750,000-km2 island has lost 62% of its old-growth forests within the last 40 years. Efforts to protect and restore the remaining forests of Borneo hinge on recognising the ecosystem services they provide, including their ability to store and sequester carbon.

Taxonomy in the light of incongruence: An updated classification of Malvales and Malvaceae based on phylogenomic data

TAXON, Volume 74, Issue 2, Page 361-385, April 2025.
Abstract Malvales is a diverse order of flowering plants, economically and ecologically relevant, and it is known for its broad morphological variability. Recent phylogenomic studies have revealed a complex evolutionary history for the order, including localised phylogenetic discordances among nuclear loci.

Molecular insights into Neotropical bird-tick ecological associations and the role of birds in tick-borne disease ecology [PDF]

arXiv, 2014
Ticks are important vectors of emerging zoonotic diseases. While adults of many tick species parasitize mammals, immature ticks are often found on wild birds. In the tropics, difficulties in species-level identification of immature ticks hinder studies of tick ecology and tick-borne disease transmission, including any potential role for birds.

Next‐generation sequencing sheds new light on a major lineage of Acanthaceae, clarifying previously uncertain relationships in Barlerieae

TAXON, EarlyView.
Abstract The Acanthaceae tribe Barlerieae is an understudied lineage that consists of ca. 500 species, many of which are rare and range restricted. Though understudied, it is clear that many species play vital roles in tropical ecosystems, including supporting a wide range of pollinators and herbivores. The tribe contains 13 genera, the two largest and

Genetic assignment of illegally trafficked neotropical primates and implications for reintroduction programs [PDF]

arXiv, 2019
The black and gold howler monkey (Alouatta caraya) is a neotropical primate that faces the highest capture pressure for illegal trade in Argentina. We evaluate the applicability of genetic assignment tests based on microsatellite genotypic data to accurately assign individuals to their site of origin.

Phylogenomics of African Melastomateae (Melastomataceae): Revisiting generic relationships, placement of three enigmatic taxa and description of two new genera

TAXON, EarlyView.
Abstract Evolutionary relationships within the Melastomateae, a diverse tribe within the Melastomataceae, are not yet completely resolved, and some putatively paleoendemic taxa that might alter relationships are still unsampled. This study employs a phylogenomic approach, utilizing target capture data, to revisit generic relationships and shed light on

New species of the Eiphosoma dentator (Fabricius, 1804) species-group (Hymenoptera, Ichneumonidae, Cremastinae) from Brazil

Brazilian Journal of Biology
A new species of Eiphosoma Cresson, 1865 (Hymenoptera, Ichneumonidae) is described based on five specimens collected in organic crops areas in Araraquara and Cravinhos municipalities, São Paulo State, Brazil. A diagnostic key to the neotropical Eiphosoma
