Description

Enregistrements de données

Les données de cette ressource données d'échantillonnage ont été publiées sous forme d'une Archive Darwin Core (Darwin Core Archive ou DwC-A), le format standard pour partager des données de biodiversité en tant qu'ensemble d'un ou plusieurs tableurs de données. Le tableur de données du cœur de standard (core) contient 302 enregistrements.

1 tableurs de données d'extension existent également. Un enregistrement d'extension fournit des informations supplémentaires sur un enregistrement du cœur de standard (core). Le nombre d'enregistrements dans chaque tableur de données d'extension est illustré ci-dessous.

Cet IPT archive les données et sert donc de dépôt de données. Les données et métadonnées de la ressource sont disponibles pour téléchargement dans la section téléchargements. Le tableau des versions liste les autres versions de chaque ressource rendues disponibles de façon publique et permet de tracer les modifications apportées à la ressource au fil du temps.

Couverture géographique

Data were collected in 50-m sampling reaches distributed across the entire watershed of the Sabor River and its main tributaries (e.g., Maçãs, Angueira), and they are located in the municipalities of Torre de Moncorvo, Alfândega da Fé, Mogadouro, Macedo de Cavaleiros, Bragança and Vimioso.

Couverture taxonomique

The taxonomic coverage of this dataset spans 1 phylum, 1 class, 3 orders, 5 families, 13 genera and 14 species.

Couverture temporelle

Données sur le projet

The dataset contains records of Fishes (Pisces) collected in the River Sabor (NE Portugal) in 2012-2020, in the scope of a study aiming to understand the temporal dynamics of fish communities in relation to natural and anthropogenics drivers in a Mediterranean watershed. The study is part of research carried out at the Long Term Ecological Research Site (LTER) of Baixo Sabor (lter_eu_pt_002; https://deims.org/45722713-80e3-4387-a47b-82c97a6ef62b). The occurrence and abundance of the target taxa were documented through 27,514 records of individuals. The most abundant species (>2,000 records) were Luciobarbus bocagei (6,166 individuals), Pseudochondrostoma duriense (4,894), Squalius caroliterii (4,693), Squalius alburnoides (3,620), Lepomis gibbosus (2,910), and Gobio lozanoi (2,360). The taxonomy of fish recorded as Achondrostoma arcasii is currently under evaluation, and so the identity of the species will be updated in the near future. Part of these data has already been analised and published (Ferreira et al., 2016; Mota-Ferreira et al., 2021). The dataset will be regularly updated with additional data from future sampling years.

Méthodes d'échantillonnage

The data was collected between 2012 and 2020, using standard electrofishing protocols (INAG, 2008) in a stream stretch of 50 meters for 15-25 minutes, with longer surveys in wider and deeper streams to properly cover the stretch. Within each segment, fish were sampled using a single anode electrofishing gear (350-750V, 3-5A, DC). Electrofishing was always conducted by the same operator, while a second operator was tasked with the netting of the displaced fish. All captured individuals were identified on site and released after the sampling session. In accordance with the Portuguese legislation, all individuals belonging to exotic species were euthanized, instead of being returned to the wild. All sampling were conducted under the appropriate permits of Portuguese conservation authority, the Instituto da Conservação da Natures e Florestas (ICNF). Details of the methods are available in Ferreira et al. (2016) and Mota-Ferreira et al. (2021).
