Prints a human-readable summary of the biome classifications shipped with the package. For each requested classification the function prints the publication, the criteria and methodology used to define the classes, a short description, the number of biome classes, the biome scheme number, and a list of biome-class names with their raster values.

Usage

biomes_info(x = NULL)

Arguments

x

Integer vector of biome scheme numbers between 1 and 31. If NULL (the default), information for all 31 schemes is printed.

Value

Invisibly returns the integer vector of biome scheme numbers that was printed. The function is called for its side effect of printing to the console.

Details

This is the interactive sibling of the biomes_information data set: use biomes_information when you want the raw metadata table (e.g. to subset, filter, or join programmatically), and biomes_info() when you want a quick read of the most relevant fields for a specific biome scheme.

See also

biomes_information for the underlying metadata table and biomes_legend for the mapping from raster values to biome names.

We digitized, the third edition (Schultz, 2002) because this map includes mountains (only shown in newer versions from 2002, 2008, and 2016) and large parts of Antarctica (only shown in older versions from 1988, 1995, and 2002). “Ecozones of the Earth” is the translated title.

#> Description: The biogeographic landscape belts are adapted from Troll & Paffen (1964) considering climatic characteristics in combination with large-scale vegetation patterns from Schmithüsen (1976) and soil characteristics provided by Ganssen & Hädrich (1965). “Landscape belts of the Earth” is the translated title. The original title is “Die Landschaftsgürtel der Erde” (German). The map shown was reissued by Schulze et al. (2019).

#> Name: Atlas of biogeography (Schmithüsen, 1976)
#> 
#> Biome scheme number: 29
#> 
#> Criteria: Climate (temperature, potential evapotranspiration), potential natural vegetation, soil, topography, elevation
#> 
#> Methodology: Biogeographic analysis
#> 
#> Description: An underlying assumption of the Atlas of Biogeography is that vegetation patterns mirror climatic conditions and are furthermore influenced by regional geological effects and disturbances. Geographical units are defined by zonal natural vegetation with climax stages that cannot be distinguishing by sharp gradients. Anthropogenic effects are not considered in this theoretical concept. The map was adapted by Sitte et al. (2002) and by Pfadenhauer & Klötzli (2014). “Atlas of Biogeography” is the translated title. The original title is “Atlas zur Biogeographie” (German).

#> Name: Vegetation and climate (Walter, 1964, 1968; Walter & Breckle, 1970; Breckle & Rafiqpoor, 2019)
#> 
#> Biome scheme number: 31
#> 
#> Criteria: Bio-physical environmental parameters including temperature, precipitation, solar radiation, soil characteristics, flora and fauna, continentality and maritime influence, snow cover
#> 
#> Methodology: Classification according to defined thresholds on climatic data, vegetation proxies and surface cover indices
#> 
#> Description: For this classification, biomes are defined as consistent terrestrial ecological regions to form habitats which correspond to relatively uniform landscapes. Those fundamental global ecological units are characterized by similar vegetation and fauna. Important shaping factors are climate and soil. The concept includes ecotones which mark small-scale transition zones between distinct areas of certain exclusive classes. Zonobiomes are zonally connected and azonal relief units, like mountain systems, are defined as orobiomes.  The first version consisted of two volumes with the original title “Die Vegetation der Erde in öko-physiologischer Betrachtung“ (Walter, 1964, 1968). There have been several later English and German editions of this fundamental book series over the past decades. Those include among others Walter (1973, 1979, 1984, 1990) and Walter & Breckle (1985, 1991, 1999). The map consulted in this inventory was taken from the last edition by Breckle & Rafiqpoor (2019).

#> Name: Global vegetation patterns of the past 140,000 years (Allen et al., 2020)
#> 
#> Biome scheme number: 1
#> 
#> Criteria: Carbon mass, LAI, and plant functional types
#> 
#> Methodology: Modelling with the global dynamic vegetation Lund-Potsdam-Jena General Ecosystem Simulator
#> 
#> Description: Global biomes were simulated over the past 140,000 years. Input factors to the dynamic global vegetation model included reconstructed atmospheric CO2 concentrations, Earth's obliquity and paleo- as well as pre-industrial climate simulations by HadCM3. Biomes were assigned according to specified ranges of vegetation carbon mass and leaf area index (LAI) of functional plant types based on consistent rules.
