A surprising discovery was made by CSIRO botanists which revealed the daisy fleabane (thought to be a rare Australian species) is an introduced plant! Molecular data suggests it likely hails from the Northern hemisphere as it is not distinctly different from the widespread bitter fleabane. 🔗⬇️

Origins of the rare Australian daisy Erigeron conyzoides and its implications for biological control research and conservation management

Context Confidence in risk analyses for weed biological control (biocontrol) agents is underpinned by knowledge of the phylogenetic associations between the target weed and off-target plant species,…

Addition and removal experiments by McDougall et al. in subalpine grassland within Kosciuszko National Park reveal that the invasive Ox-eye daisy affects grassland diversity. Luckily, undisturbed communities seem resilient to the daisy's invasion despite its abundance. 🔗 ⬇️

To get started we are launching a citizen science project on iNaturalist where anyone can contribute images of honeybees or native pollinators visiting native flowers so we can have a baseline for how flower visitation changes before and after varroa mite reaches different parts of the country 4/5

There is a huge need for more research on pollination in native species and support for existing work. Collection of baseline data is crucial as is monitoring already threatened species. There may also be unexpected impacts arise through interactions with other threats like fragmentation or fire 3/5

We found a decline in feral honeybees will be good news for some plants and bad news for others. But we found major gaps in our knowledge of how honeybees influence native plant pollination and pollinators. The loss of feral honeybees due to varroa mite is an opportunity to fill these gaps 2/5

A figure showing the impending spread of varroa mite across Australia and the possibly positive effects of a reduced honeybees on fruit set for some native plant species

Varroa mite arriving in Australia has been a big worry for agriculture and bee keeping but it will also result in a massive decline in feral honeybee populations. This will affect many native plant species visited by honeybees, our new paper aimed to understand what those effects might be 1/5

A new #OpenAccess article in #AusJBotany identifies potential consequences of the spread of varroa mite and highlights the large knowledge gaps that currently limit understanding of the subsequent impacts on the Australian flora. @ausjbotany.bsky.social www.publish.csiro.au/bt/BT24020

Another Advanced Field Biology field course completed up at the UNSW Smith's Lake field station. The ⁦‪students looked at the impacts of different fire histories on plants, caught and identified bats and other critters and generally got out into the wild 😊 #ecology #fieldwork
