“…This is reinforced by a relatively low number of species given the extent of the area sampled (S2.6 Fig in S2 File) and the high estimation of species richness for the whole Amazon [45]. Although the origin of the Amazonian flora was dated for many major clades back to the Late Cretaceous or Palaeocene, more recent landscape dynamics have led to high diversification rates in the last 5 million years, contributing to a high species diversity of the region [46].…”

Colombia’s bioregions as a source of useful plants

The aim of our study was to assess the importance of different Colombian bioregions in terms of the supply of useful plant species and the quality of the available distribution data. We assembled a dataset of georeferenced collection localities of all vascular plants of Colombia available from global and local online databases. We then assembled a list of species, subspecies and varieties of Colombia’s useful plants and retrieved all point locality information associated with these taxa. We overlaid both datasets with a map of Colombia’s bioregions to retrieve all species and useful species distribution records in each bioregion. To assess the reliability of our estimates of species numbers, we identified information gaps, in geographic and environmental space, by estimating their completeness and coverage. Our results confirmed that Colombia’s third largest bioregion, the Andean moist forest followed by the Amazon, Pacific, Llanos and Caribbean moist forests contained the largest numbers of useful plant species. Medicinal use was the most common useful attribute across all bioregions, followed by Materials, Environmental uses, and Human Food. In all bioregions, except for the Andean páramo, the proportion of well-surveyed 10×10 km grid cells (with ≥ 25 observation records of useful plants) was below 50% of the total number of surveyed cells. Poor survey coverage was observed in the three dry bioregions: Caribbean deserts and xeric shrublands, and Llanos and Caribbean dry forests. This suggests that additional primary data is needed. We document knowledge gaps that will hinder the incorporation of useful plants into Colombia’s stated plans for a bioeconomy and their sustainable management. In particular, future research should focus on the generation of additional primary data on the distribution of useful plants in the Amazon and Llanos (Orinoquia) regions where both survey completeness and coverage appeared to be less adequate compared with other regions.

“…We believe that the highly disjointed geographic distribution of T. coriaceus likely emerges from an interaction between the i) extensive knowledge gaps throughout the Amazonia (e.g., Mayer et al, 2019;Cracraft et al, 2020), and ii) the explosive reproductive behavior of T. coriaceus, since that the individuals of this species remain inactive most of the year and become active by just a few days (Duellman, 2005), which hamper its records during field surveys.…”

Herein, we report a new record of the milk frog Trachycephalus coriaceusfor the Brazilian southern Amazonia and provide an updated geographic distribution map. We collected one specimen of T. coriaceuson 8 november 2016, during a nocturnal survey inside a dense ombrophilousforest in the right bank of the Teles Pires River, municipality of Jacareacanga, southern of Pará State. The record of T. coriaceusto Jacareacanga is the first to the State. The disjoint geographic distribution of this species along de Amazonia may just reflect the paucity of amphibian knowledge throughout this biome and the difficulty to detect this species in the field, given its explosive reproductive behavior.

The challenges and potential of geogenomics for biogeography and conservation in Amazonia

Amazonia has a very high, although still incompletely known, species diversity distributed over a mosaic of heterogeneous habitats that are also poorly characterized. As a result of this multi‐faceted complexity, Amazonia poses a great challenge to geogenomic approaches that strive to find causal links between Earth's geological history and biotic diversification, including the use of genomic data to solve geologic problems. This challenge is even greater because of the need for interdisciplinary approaches despite the difficulties of working across disciplines, where misinterpretations of the literature in disparate research fields can produce unrealistic scenarios of biotic‐geologic linkages. The exchange of information and the joint work of geologists and biologists are essential for building stronger and more realistic hypotheses about how past climate may have affected the distribution and connectivity among populations, how the evolution of drainage networks influenced biotic diversification, and how ecological traits and species interactions currently define the spatial organization of biodiversity, and thus how this organization has changed in the past and may change in the future. The heterogeneity of Amazonia and the different effects of historical processes over its distinct regions and ecosystems have to be more completely recognized in biogeography, conservation; and policymaking. In this perspective, we provide examples of geological, climatological; and ecological information relevant to studies of biotic diversification in Amazonia, where recent advances (and their limitations) may not be apparent to researchers in other fields. The three examples, which include the limitations of climate model outputs, the complicated evolution of river drainages; and the complex link between species and their habitats modulated by ecological specialization, are a small subsample intended to illustrate the urgency for more integrated interdisciplinary approaches.
