説明
In this database, we present plant-animal interactions in the lowland forest community of Doñana National Park during the fruiting season. Our focus primarily lies on plant-frugivore interactions but we also report data on animals that visits fruiting plants. We used DNA-based molecular analysis on faecal samples and regurgitated seeds from fleshy-fruited plant species to identify the frugivore species involved in each dispersal event and other animal species visiting plants. Sampling was conducted over the fruiting seasons from 2018 to 2022. We used seed traps and transects that were stratified across several forest and scrubland communities. Our dataset contains 13,835 pairwise interaction records derived from 8,783 collected samples. Of these records, 6,358 correspond to frugivorous interactions, while 7,477 correspond to animals visiting plants. The dataset encompasses 19 plant species, 39 bird species (with 30 of them being frugivores), 7 mammal species (with 6 of them being frugivores), 2 reptile species, 2 amphibia species, and 1 insect species. Each interaction is recorded as an event, defined by the encounter of species at a specific location and time. The interactions are further described in terms of the partners involved, allowing for multiple occurrences within the same event.
These data can be used to assess frugivory and seed dispersal networks, explore frugivore contributions to seed rain in different microhabitats, or frugivores’ preference for fruit/seed sizes. They provide occurrence data for animals (mainly birds) associated with specific plant species, enabling the study of animal dynamics and behavior. Moreover, they support big-data approaches for generating species interaction models and macro-ecological analyses. This dataset greatly enhances our understanding of animal-plant interactions, particularly in the context of frugivory.

プロジェクトデータ
The project SUMHAL aims at implementing a strategy for biodiversity conservation in the western Mediterranean hotspot by setting a technologically efficient and scientifically robust system. The project combines fieldwork and virtual research environments for the recording, storing, analysis, and dissemination of the conservation status and threats of biodiversity in Andalusia (Southern Spain). The main objective of WP5 is to characterize and quantify the interactome of biodiversity in protected areas within the RN2000, by examining the size and diversity of ecological functions integrated within complex networks of ecological interactions among species. The thematic elements of eLabs-BioINTERACT encompasses different forms of ecological interaction: including predator-prey, herbivory, pollination, seed dispersal, parasitism, plant-plant facilitation, mycorrhizae-plants, among others. Current online interaction databases are limited and there are no standards for ecological interaction data, which is crucial for the digitization, sharing and aggregation of interaction data on a large scale. SUMHAL’s WP5 aims to produce useful information for the conservation of biodiversity and biotic interactions by mobilizing information from both field data recording and bibliographic compilation, structured in standardized formats for free access.

収集方法
Our sampling design aimed to capture the diverse range of frugivory interactions in the Doñana National Park. To achieve this goal, we covered the main Mediterranean plant communities hosting the diversity of fleshy-fruit species in the area, including (i) Juniperus-dominated forests coexisting with Mediterranean scrub and scattered pines; (ii) sclerophyllous scrubland dominated by Pistacia lentiscus, coexisting with a total of 28 fleshy-fruited plant species; (iii) sparse mixed scrubland with a wide amount of fleshy-fruited plant species, occasionally dominated by Arbutus unedo, Olea europaea or Myrtus communis, (iv) humid scrub located in depressions, dominated by Rubus ulmifolius. We used DNA-barcoding techniques of faecal samples and regurgitated seeds to estimate the intensity of interactions between frugivores and plants, as well as between fruiting plants and animals in general. Our sampling approach involved placing seed traps beneath the crowns of various plant species, which served as potential fruit sources or bird perching spots. To protect the seed traps from seed predation, we covered them with a 1 cm mesh. The sampled area beneath each focal plant varied, typically corresponding to one tray area. However, for larger plants, we installed two trays to ensure maximum coverage. We occasionally collected scats within a delimited rectangular soil surface adjacent to the tray or along open transects to increase the sampled surface area. Overall, we sampled a total of 308 sites, including 105 sites under juniper individuals, 80 sites under Pistacia individuals, and 123 sites under a variety of fleshy and non-fleshy fruiting individuals (including up to 11 plant species).
| Study Extent | We conducted our study in the Doñana National Park between 2018 and 2022, covering different plant communities in the area. Sampling was carried out along the fruiting season, which typically spans from September to May, although the exact timing varied among plant species. Each plant community was sampled during one or two consecutive fruiting seasons to ensure comprehensive coverage of frugivorous animal-plant interactions. |

| Quality Control | The dataset includes quality measures regarding the lab procedure and animal identification: (i) the percentage of similarity between sequences, from the focal sample and from the reference database, and (ii) the sequence length. In the Juniperus-dominated forest, successful identification was defined as sequences with a similarity of >98% and a minimum length of 100 bp. In the Lentiscus-dominated scrubland, we only considered samples over 150 bp length and over 90% of identity similarity. Most samples scored over 99% similarity (mean length = 288 bp, mean similarity = 99.31%). For the subset of samples with similarity in between 90%-99% (n = 228), the second species identified had to be further than 2% similarity distance, or absent in the geographical range area, as an additional quality requisite. In mixed scrubland, the main criteria to assign a sample to an animal species was the second species identified had to exhibit a similarity distance greater than 2% from the first species. The dataset includes genetic sequence information for each animal sample, ensuring result reproducibility. Furthermore, for certain focal plants, interaction accumulation curves (IAC) were estimated to assess the completeness of DNA-barcoding sampling (Colwell & Coddington 1994, Jordano 2016), as described in Quintero et al. 2023 Suppl. Mat. B.3. |
Method step description:
- The seed traps were scanned every ten to fifteen days, and all samples present in the trays were collected, regardless of whether they contained seeds or not. A total of 2.993 samples were collected from the Juniper forest, 3.029 samples from the Pistacia-dominated scrubland, and 2.761 samples from the mixed scrublands. When abundant samples were found in the trays and appeared identical (such as multiple regurgitated seeds below a perch), a subset of samples was collected for barcoding. The remaining seed count was then assigned to the same species identified in the collected subset. These imputed samples account for approximately 8% of the total samples collected in the Pistacia-dominated scrubland. The number of samples collected varied among focal plants. We initially analyzed all available samples per plant site, excluding those with significantly degraded material, up to a maximum of 40 samples. However, in the Pistacia-dominated scrubland, certain plants yielded more than 40 samples (reaching up to 200 samples in some cases). To ensure comprehensive sampling, we gradually increased the number of DNA-barcoded samples until the sampling completeness curves reached saturation. This rigorous approach ensured a robust characterization of the frugivore-plant assemblage in Doñana. Plant species of seeds from faces or regurgitations were identified through direct observation by at least one trained and qualified person. Lab procedure: The identification of disperser species was based on the mitochondrial DNA region (COI: cytochrome c oxidase subunit I). For birds, we used a fragment of 464-bp for samples from Pistacia-dominated scrubland, 272-bp for samples from Juniperus and mixed fleshy fruit plant species, and 758- or 175-bp for mammals. DNA extraction was performed using the GuSCN/ silica protocol and PCR amplification followed the protocol described by González-Varo et al. (2014) with minor modifications (Quintero et al. 2023 Suppl. Mat. B.1). All bird samples were amplified by PCR using the primer pair COI-fsdF /COI-fsdR for samples from Pistacia-dominated scrubland and the primer pair COI-fsd-degF/ COI-fsdR for the remaining samples (González-Varo et al. 2017). Mammal samples were amplified following the protocols and primers of Alcaide et al. and additionally Schaffer et al. 2017 (only primer pair In1f/In1r) for samples from mixed scrubland. The resulting sequences (i.e., barcodes) were revised and edited using 4Peaks software (http://nucleobytes. com/4peaks/). The identified species was then determined by comparing the sequences against the "BARCODE OF LIFE DATA" (BOLD) and Nucleotide Basic Local Alignment Search Tool (BLAST from NCBI) reference databases. For the bird samples that did not amplify, we amplified the 272-bp fragment from the 464-bp COI DNA region using the primers COI-fsd-degF and COI-fsdR and the nested PCR protocol described in González-Varo et al. (2017).
