Plant-Bird_SeasonalNetworks&PlantTraits_2009-2010_ManuPeru

Irene Bender
1. Interactions between resource and consumer species result in complex ecological networks. The overall structure of these networks is often stable in space and time, but little is known about the temporal stability of the functional roles of consumer species in these networks. 2. We used a trait-based approach to investigate whether consumers (frugivorous birds) show similar degrees of functional specialisation on resources (plants) in ecological networks across seasons. We additionally tested whether closely related...

Migratory behaviour in birds: A classification across all living species

A. Eyres
The uploaded dataset contains a classification of migratory behaviour for all 10596 extant species of birds (Aves). The dataset focuses on seasonal migration, i.e. movements causing an individual adult bird to be found in different locations over the course of one year, excluding every day routine movements (e.g. foraging movements) and one-way dispersal movements by juveniles (natal dispersal) or adults. Types or categories of migratory behaviour were recorded and classified from descriptions in the Handbook...

Gallegos et al. 2014 Secondary dispersal by ants promotes forest regeneration after deforestation

Silvia Gallegos
We studied the effects of secondary dispersal on seed predation, germination and seedling recruitment of the primarily bird-dispersed tree Clusia trochiformis in a tropical montane forest in Bolivia. We carried out exclosure experiments that allowed or excluded access to seeds by vertebrates in three habitat types (forest interior, degraded habitat close to and degraded habitat far from the forest margin) in a spatial block design at six sites. We offered a total of 1,440 seeds...

Global Alien Species First Record Database

H. Seebens
The Global Alien Species First Record Database (GASFiReD) was created to analyse the accumulation of alien species through time in a consistent way across taxonomic groups and regions. A first record denotes the year of first occurrence of an established alien species in a region. The first records were gathered from 102 data sources including online databases, scientific publications, reports and personal collections. The database consists of >45,000 first records of nearly 17,000 species from...

Effects of phylogeny and geography on ecomorphological traits in passerine bird clades

Anna Phillips
Aim: Closely related species are often morphologically similar due to their shared evolutionary history. This similarity can restrict their geographic distribution, as processes such as interspecific competition might prevent species from co-occurring if they resemble each other too closely. There is still little understanding of the relative strengths of such phylogenetic and geographic effects on the morphological diversity of species within a clade. Here, we compare phylogenetic effects with geographic effects across multiple clades of...

Morphological trait matching shapes plant–frugivore networks across the Andes

Irene Bender
Interactions between resource and consumer species are organized in ecological networks. Species interactions in these networks are influenced by the functional traits of the interacting partners, but the generality of trait-based interaction rules and the relationship between functional traits and a species’ specialization on specific interaction partners are not yet understood. Here we combine data on eight interaction networks between fleshy-fruited plants and frugivorous birds sampled across the tropical and subtropical Andean range. We test...

Fruit removal by seed-dispersing animals in the Colombian Andes

Munoz M.
Fruit removal. This data set was collected during the period February-November 2012 along an altitudinal gradient in the Andes of Colombia (Cordillera Central, in Risaralda). We established ten plots (100 x 20 m), each plot was separated of each other 100 m elevation, from 1,800 m up to 2,700 m above sea level. In each plot, we marked and identified each individual plant bearing ripe fruits and recorded the number of fruits that were removed...

Miklos Balint
High-throughput metabarcoding studies on fungi and other eukaryotic microorganisms are rapidly becoming more frequent and more complex, requiring researchers to handle ever increasing amounts of raw sequence data. Here we provide a flexible pipeline for pruning and analyzing fungal barcode (ITS rDNA) data generated as paired-end reads on Illumina MiSeq sequencers. The pipeline presented includes specific steps fine-tuned for ITS, that are mostly missing from pipelines developed for prokaryotes. It (i) employs state of the...

Seedlings recruited of 22 plant species in the Colombian Andes

Munoz M.
In the Andes of Colombia (Cordillera Central, in Risaralda) we established ten plots (100 x 20 m), along an elevational gradient from 1,800 m up to 2,700 m above sea level. Each plot was separated of each other 100 m elevation. In each plot, we set up a data logger to measured abiotic conditions, i.e. temperature and humidity. We also counted all adult fleshy-fruited plant species in each plot, including individuals that were not bearing...

FastQFS A Tool for evaluating and filtering paired-end sequencing data generated from high throughput sequencing

Sharma
Next generation sequencing (NGS) technologies generate huge amounts of sequencing data. Several microbial genome projects, in particular fungal whole genome sequencing, have used NGS techniques, because of their cost efficiency. However, NGS techniques also demand for computational tools to process and analyze massive datasets. Implementation of few data processing steps, including quality and length filters, often leads to a remarkable improvement in the accuracy and quality of data analyses. Choosing appropriate parameters for this purpose...

Morphological traits determine specialization and resource use in plant-hummingbird networks in the neotropics

Maria Maglianesi
Ecological communities are organized in complex ecological networks. Trait-based analyses of the structure of these networks in highly diversified species assemblages are crucial for improving our understanding of the ecological and evolutionary processes causing specialization in mutualistic networks. In this study, we assessed the importance of morphological traits for structuring plant-hummingbird networks in Neotropical forests by using a novel combination of quantitative analytical approaches. We recorded the visitation of hummingbirds to plant species over an...

Genome analyses of the sunflower pathogen Plasmopara halstedii provide insights into effector evolution in downy mildews and Phytophthora

Thines M. Sharma R.
Background Downy mildews are the most specious group of oomycetes and affect crops of great economic importance. So far, there is only a single deeply-sequenced downy mildew genome available, from Hyaloperonospora arabidopsidis. Further genomic resources for downy mildews are required to study their evolution, including pathogenicity effector proteins, such as RxLR effectors. Plasmopara halstedii is a devastating pathogen of sunflower and a potential pathosystem model to study downy mildews, as several Avr-genes and R-genes have...

We sampled weighted plant-bird interaction networks at two sites in the Manú Biosphere Reserve in the Andes of south-east Peru: Wayqecha (13.2S, 71.6W, 3000 m, upper montane rainforest) and San Pedro (13.1S, 71.6W, 1500 m, lower montane rainforest). At each site, we installed plots of 100 m x 30 m (six plots in Wayqecha, eight plots in San Pedro) and sampled networks four times approximately every three months between December 2009 and September 2010. In...

Comparative genomics including the early-diverging smut fungus Ceraceosorus bombacis reveals signatures of parallel evolution within plant and animal pathogens of fungi and oomycetes

Sharma R.
Ceraceosorus bombacis is an early-diverging lineage of smut fungi and a pathogen of cotton trees (Bombax ceiba). To study the evolutionary genomics of smut fungi in comparison with other fungal and oomycete pathogens, genome of Ce. bombacis was sequenced and comparative genomic analyses were performed. The genome of 26.09 megabases encodes for 8024 proteins, of which 576 are putative secreted effector proteins (PSEPs). Orthology analysis revealed 30 ortholog PSEPs among six Ustilaginomycotina genomes, the largest...

Functional structure and specialization in three tropical plant-hummingbird interaction networks across an elevational gradient in Costa Rica

Maria Maglianesi
Understanding causes of variation in multispecies assemblages along spatial environmental gradients is a long-standing research topic in ecology and biogeography. Ecological networks comprising interacting species of plants and pollinators are particularly suitable for testing effects of environmental gradients on the functional structure and specialization in multispecies assemblages. In this study, we investigated patterns in functional assemblage structure and specialization of hummingbirds at the individual and species level along a tropical elevational gradient. We mist-netted hummingbirds...

Foraging preferences of hummingbirds on artificial and natural flowers; 2011-2012; Costa Rica

Maria Maglianesi
1. In plant-pollinator networks, the floral morphology of food plants is an important determinant of the interaction niche of pollinators. Studies on foraging preferences of pollinators combining experimental and observational approaches may help to understand the mechanisms behind patterns of interactions and niche partitioning within pollinator communities. 2. In this study, we tested whether morphological floral traits were associated with foraging preferences of hummingbirds for artificial and natural flower types in Costa Rica. We performed...
