Influences of remnant size, spacing pattern and connectivity on population boundaries and demography in euros Macropus robustus living in a fragmented landscape

摘要: In the 14 million ha wheatbelt of Western Australia, depending on location, only 1·7% to 12·5% native vegetation remains in fragments mostly 100 ha), individuals were also sedentary. Some included smaller remnants within 700 m their home ranges, usually moving along connecting corridors between remnants. Occasionally, a few made excursions several km outside normal ranges either overnight or over months. areas where all small (<30 lived alone groups, frequently Overall, euros 1680-km2 study area appear be separated into number metapopulations, some which have very numbers animals. Within movements populations dependent availability ‘stepping stones’ and corridors. two had low densities euros, juveniles per adult female significantly lower than systems with higher densities. Long-term survival these is questionable.
