Faecal nutrient deposition of domestic and wild herbivores in an alpine grassland

The Dataset.xlsx contains data of the faecal nutrient content of four herbivores species (chamois, sheep, horse, and cow) in a alpine grassland in the Spanish Pyrenees. Other information is also added, like the body size, feeding strategy, and the dung dry weight of each species. Our main main objectives to study were 1) explore if herbivore dung stoichiometry differed between species and body size groups, 2) determine if seasonal differences in herbivore dung stoichiometry persisted in our study system, and 3) quantify the amount of nutrients released annually by each herbivore.
The quantification of the amount of nutrient released annually (objective 3) can be found in the Dataset.xlsx in the datasheet annual_input.
The fie R_script.zip contains the dataset used in a csv delimited by commas, and the R script used to answer our objectives 1) and 2).
We have found differences in faecal nutrient content due to seasonality and body size. In addition, cattle is by far the herbivore with more fertilization effect in the ecosystem.
