Noisy miner abundance

Description

The number of noisy miners detected in various 2 hectare transects in buloke woodland patches within the Wimmera Plains of western Victoria, Australia

Usage

data(nminer)

Format

A data frame with 31 observations on the following 9 variables.

Miners

the presence or absence of noisy miners; a numeric vector with levels 1 (present) or 0 (absent)

Eucs

the number of eucalypts in each 2 hectare transect; a numeric vector

Area

the area in hectares of contiguous remnant patch of vegetation in which the transect was located; a numeric vector

Grazed

whether the area was grazed or not; a numeric vector with levels 0 (grazed) or 1 (not grazed)

Shrubs

whether shrubs were present in the transect or not; a numeric vector with levels 1 (shrubs present) or 0 (shrubs not present)

Bulokes

the number of buloke trees in each 2 ha transect; a numeric vector

Timber

the number of pieces of fallen timber in the transect; a numeric vector

Minerab

the number of noisy miners (abundance) observed in three 20 minute surveys; a numeric vector

Details

The data gives the number of noisy miners detected in various two hectare transects in buloke woodland patches within the Wimmera Plains of western Victoria, Australia. The noisy miner is a small but aggressive native Australian bird.
