Data on terrestrial ferns species richness, abundance, and functional traits in Mashpi Rainforest Biodiversity Reserve in the Ecuadorian Chocó

2023 , Salazar, Laura , Peña P. , Segura R. , Roldán M.

This data paper summarizes the data of a first survey of terrestrial ferns at Mashpi Biodiversity Reserve, an Ecuadorian Chocó forest relict, one of the most biodiverse areas in the world. We established 10 permanent plots of 400 m2 distributed in two elevational levels (800 and 1000 m a.s.l.) to register all species per plot and the abundance per species. In addition, we measured two morphological leaf functional traits of the species. We include a file with three tables, the first one includes a species list with scientific names and vouchers. The second one includes the abundance of each species per plot. The third one contains measurements of the leaf length and leaf thickness of several leaf samples of 28 species, representing the leaf functional traits of the species. This article also includes a table with coordinates and elevations of the plots and five figures with information about the number of genus and species per family, geographic location of plots and, the methodology for data collection. These data can be useful for plant ecologists to assess future changes of fern species composition and leaf functional traits of ferns caused by climate change and other threats at the study area. © 2022 The Authors

Dietary data of a highly biodiverse anuran assemblage in the Ecuadorian Amazon

2022 , Menéndez-Guerrero, P.A. , Ron, S.R. , Carvajal-Endara, S.

This dataset reports the diet composition of a highly diverse anuran assemblage in the Ecuadorian Amazon region. In 2001 we examined the diet of an assemblage of frogs from Yasuní National Park. We describe the diet of 396 adult individuals, belonging to 35 species, based on their gastrointestinal contents. Using a stereoscopic microscope, we were able to identify 4085 prey items, and classified them in 71 categories. Also, we used a digital caliper to measure the size and estimate the volume of prey items that were found intact. In addition to diet composition, we provide information of all specimens that were examined including, museum number, family name, species name, and place and date of collection. Finally, we present an anuran–prey interaction network figure to visualize species interactions. This is the first report of the diet composition of an anuran assemblage from Yasuní National Park. It contributes to the understanding of trophic ecology of frog assemblages and the functional role of frogs in Amazonian ecosystems. In addition, our dataset helps to fill the great knowledge gap that exists about ecological interactions in the tropics. © 2022 The Author(s)

Dataset of permanent plots of trees with dbh >10cm in Mashpi rainforest biodiversity reserve, a remnant of the Chocó forest in Northern Ecuador

2020 , Toasa G. , Morochz C. , Oleas N.H.

This data reports a list of all trees DBH > 10 cm in four 50 × 50 m (0.25 ha) permanent plots at Mashpi Rainforest Biodiversity Reserve in the Ecuadorian Chocó forest. Plots were established within an altitudinal gradient from 800 to 1200 m. We collected, labelled, measure and identify all trees found within the plots. All voucher specimens are available at the herbarium of Universidad Tecnológica Indoamérica (HUTI) in Quito, Ecuador. We found a total 133 stems representing 93 species and 36 families. Each plot had between 27 and 40 trees. Our list of species includes four threatened species under IUCN criteria. We also report the number of individuals of each species and its diameter at breast height (DBH) and height. This information is a baseline for further studies to contribute to the conservation of the Chocó, one of the 35 biodiversity hotspots is the Tumbes-Chocó-Magdalena. Even though this area is one of the most biodiverse in the planet, the botanical composition of the Chocó is still poorly known. © 2020 The Author(s)

Trees of Amazonian Ecuador: a taxonomically verified species list with data on abundance and distribution

2019 , Guevara Andino J.E. , Pitman N.C.A. , Ulloa Ulloa C. , Romoleroux K. , Fernández-Fernández D. , Ceron C. , Palacios W. , Neill D.A. , Oleas Gallo, Nora Helena , Rivas Torres G. , Altamirano P. , ter Steege H.

We compiled a data set for all tree species collected to date in lowland Amazonian Ecuador in order to determine the number of tree species in the region. This data set has been extensively verified by taxonomists and is the most comprehensive attempt to evaluate the tree diversity in one of the richest species regions of the Amazon. We used four main sources of data: mounted specimens deposited in Ecuadorian herbaria only, specimen records of a large-scale 1-hectare-plot network (60 plots in total), data from the Missouri Botanical Garden Tropicos® database (MO), and literature sources. The list of 2,296 tree species names we provide in this data set is based on 47,486 herbarium records deposited in the following herbaria: Alfredo Paredes Herbarium (QAP), Catholic University Herbarium (QCA), Herbario Nacional del Ecuador (QCNE), Missouri Botanical Garden (MO), and records from an extensive sampling of 29,768 individuals with diameter at breast height (dbh) ≥10 cm recorded in our plot network. We also provide data for the relative abundance of species, geographic coordinates of specimens deposited in major herbaria around the world, whether the species is native or endemic, current hypothesis of geographic distribution, representative collections, and IUCN threat category for every species recorded to date in Amazonian Ecuador. These data are described in Metadata S1 and can be used for macroecological, evolutionary, or taxonomic studies. There are no copyright restrictions; data are freely available for noncommercial scientific use (CC BY 3.0).

NEOTROPICAL FRESHWATER FISHES: A dataset of occurrence and abundance of freshwater fishes in the Neotropics

2023 , Tobes, Ibon

The Neotropical region hosts 4225 freshwater fish species, ranking first among the world's most diverse regions for freshwater fishes. Our NEOTROPICAL FRESHWATER FISHES data set is the first to produce a large-scale Neotropical freshwater fish inventory, covering the entire Neotropical region from Mexico and the Caribbean in the north to the southern limits in Argentina, Paraguay, Chile, and Uruguay. We compiled 185,787 distribution records, with unique georeferenced coordinates, for the 4225 species, represented by occurrence and abundance data. The number of species for the most numerous orders are as follows: Characiformes (1289), Siluriformes (1384), Cichliformes (354), Cyprinodontiformes (245), and Gymnotiformes (135). The most recorded species was the characid Astyanax fasciatus (4696 records). We registered 116,802 distribution records for native species, compared to 1802 distribution records for nonnative species. The main aim of the NEOTROPICAL FRESHWATER FISHES data set was to make these occurrence and abundance data accessible for international researchers to develop ecological and macroecological studies, from local to regional scales, with focal fish species, families, or orders. We anticipate that the NEOTROPICAL FRESHWATER FISHES data set will be valuable for studies on a wide range of ecological processes, such as trophic cascades, fishery pressure, the effects of habitat loss and fragmentation, and the impacts of species invasion and climate change. There are no copyright restrictions on the data, and please cite this data paper when using the data in publications. © 2022 The Ecological Society of America.
