Spider data
Description
Abundance of hunting spiders and associated environmental variables
Usage
spider
Format
A list containing the elements
- abund
A matrix with 28 observations of abundance of 12 hunting spider species.
- x
A data frame of six (transformed) environmental variables at each of the 28 sites.
- trait
A data frame of three species trait variables for each of the 12 species.
Details
The matrix abund has the following species abundances (column name abbreviation in brackets)
Alopecosa accentuata (Alopacce)
Alopecosa cuneata (Alopcune)
Alopecosa fabrilis (Alopfabr)
Arctosa lutetiana (Arctlute)
Arctosa perita(Arctperi)
Aulonia albimana (Auloalbi)
Pardosa lugubris (Pardlugu)
Pardosa monticola (Pardmont)
Pardosa nigriceps (Pardnigr)
Pardosa pullata (Pardpull)
Trochosa terricola (Trocterr)
Zora spinimana (Zoraspin)
The data frame x has the following log(x+1)-transformed environmental variables
soil.dry - Soil dry mass
bare.sand - Cover bare sand
fallen.leaves - Cover fallen leaves / twigs
moss - Cover moss
herb.layer - Cover herb layer
reflection - Reflection of the soil surface with a cloudless sky
The data frame trait has the following variables
length (numeric) - Length (log-transformed), averaged across typical lengths (in centimetres) for male and females
(factor) - Predominant colour, "yellow" or "dark"
(factor) - Whether the spider typically has markings on it: "none", "spots" or "stripes"

Data attributed to van der Aart & Smeenk-Enserink (1975),
obtained from the spider2 directory, CANOCO FORTRAN package, with trait data added by David Warton,
exported from mvabund R package.
