Application of a deep learning image classifier for identification of Amazonian fishes. [PDF]

Ecol Evol, 2023
To address the growing prevalence of large ecological datasets combined with a need for rapid species identification tools, we describe a novel application of a computer vision model, which is built to rapidly identify Amazonian fishes from captured image data.

Beyond species means - the intraspecific contribution to global wood density variation. [PDF]

New Phytol
Summary Wood density is central for estimating vegetation carbon storage and a plant functional trait of great ecological and evolutionary importance. However, the global extent of wood density variation is unclear, especially at the intraspecific level. We assembled the most comprehensive wood density collection to date, including 109 626 records from

Allometric Constraint Predominates Over the Acoustic Adaptation Hypothesis in a Radiation of Neotropical Treefrogs. [PDF]

Integr Zool
Male frogs emit calls to attract mates and deter conspecific rivals. The evolution of these calls is thought to be linked to anatomical constraints and the acoustic characteristics of their surroundings. We tested these two factors in a radiation of 112 species of Neotropical treefrogs and found that body size and calling site affect peak frequency but

Role of the Chicamocha River Canyon on the phylogeography of humid montane forest birds in Colombia

Journal of Avian Biology, Volume 52, Issue 11, November 2021., 2021
Neotropical humid montane forest (HMF) is divided by landform discontinuities which could limit gene flow among populations. The northern Andes is a complex montane system and an excellent region to compare the role of discontinuities dividing HMFs on the phylogeography of bird species. We study phylogeographic patterns of seven HMF bird species in the
