Frontiers | Evidence of Range Shifts in Riparian Plant Assemblages in Response to Multidecadal Streamflow Declines

Riparian corridors are thought to form hydrological refugia that may buffer species and communities against regional climate changes. In regions facing a warming and drying climate, however, the hydrological regime driving riparian communities is also under threat. We examined recruitment in response to streamflow declines for species inhabiting the riparian zone in southwest Western Australia, testing the extent to which the riparian system has buffered riparian communities from the drying climate. We stratified 49 vegetation transects across the >600 mm per annum regional rainfall gradient encompassed by the Warren River Catchment. Local hydrological conditions were estimated over two 10-year periods; 1980 to 1989, and 2001 to 2010, to quantify changes in the flood regime. Mixed effects models tested the relationship between rainfall and flooding on the proportion of immature to mature individuals of 17 species of trees and shrubs common to the riparian zones. At the low-rainfall ....

Unlocking Australia's biodiversity, one dataset at a time


Credit: CSIRO
Australia s unique and highly endemic flora and fauna are threatened by rapid losses in biodiversity and ecosystem health, caused by human influence and environmental challenges. To monitor and respond to these trends, scientists and policy-makers need reliable data.
Biodiversity researchers and managers often don t have the necessary information, or access to it, to tackle some of the greatest environmental challenges facing society, such as biodiversity loss or climate change. Data can be a powerful tool for the development of science and decision-making, which is where the Atlas of Living Australia (ALA) comes in.
ALA - Australia s national biodiversity database - uses cutting-edge digital tools which enable people to share, access and analyse data about local plants, animals and fungi. It brings together millions of sightings as well as environmental data like rainfall and temperature in one place to be searched and analysed. All data are made public ....

The Country
A widespread field search for a rare Australian native bee, which hasn t been recorded for almost a century, has found that it s been there all along.
However, scientists warned it was probably under increasing pressure to survive.
Only six individual bees were ever found, and the last published record of this Australian endemic bee species, ....
