PHD opportunity in plant ecophysiology - Adelaide University, SA Closing 15 February We are looking for an PhD candidate to join an exciting research project focused on understanding heat and drought combined impacts on threatened plants’ mortality. This is a critical issue in Australia and worldwide as climate change is intensifying, leading to hotter droughts and increasing extinction risks for many species. The project will involve a substantial amount of fieldwork, glasshouse and laboratory work, as well as data analysis and writing throughout. $36,500 AUD p.a. SCHOLARSHIP + $3,000 AUD p.a. top up

Research Fellow Quantitative Ecologist - La Trobe University, VIC Closing 5 February Join a dedicated team of scientists within the Centre for Freshwater Ecosystems. We require a quantitative ecologist with skills/experience in statistical and quantitative modelling. The successful candidate will contribute to projects on flow-ecology relationships and habitat suitability modelling for freshwater organisms and will be comfortable working with large datasets, including spatial information, hydrologic data and survey records. $114,855 – $135,633 + 17% superannuation

Honours project on Mirnong restoration - RMIT, VIC Closing 31 January In collaboration with the Taungurung Land and Waters Council, we are looking for Honours students to explore factors influencing successful restoration of a favourite food plant, Mirnong (Micoseris walteri). We have capacity to develop one or more projects to analyse the soil physicochemical, microbial and environmental conditions that best support Mirnong establishment in culturally managed landscapes. The work will be a mix of lab work (microbial, soil), field work (sampling, measuring of plants and soils) and greenhouse experiments.

Black-winged Kite breeds in Denmark and Hungary for the first time Black-winged Kite has bred in Denmark and Hungary for the very first time this year, marking a significant northward advance for the striking raptor. Breeding was recorded in Hungary in the country's south-east region. Two chicks hatched and subsequently fledged from an initial clutch of four eggs. Meanwhile, the first Danish breeding record has occurred. A pair was recorded exhibiting nesting behaviour, including nest-building and mating, in central Jutland in September.

Black-winged Kite has bred in both Denmark and Hungary for the first time this year, continuing the species' range expansion into Central and Northern Europe:

Perspective Who gets the spotlight? Disparities in seabird research attention at scientific conferences Ingrid L. Pollet a b Alexander L. Bond b c Jennifer L. Lavers b c d Highlights • Decade-long review of >2,950 seabird conference abstracts. • Over 30% of seabird species are rarely or never featured at scientific conferences • Several seabirds listed as Critically Endangered have received little or no attention. • 16 seabird species are over-represented in conferences. • Southern Hemisphere seabirds require greater research attention.

Hey seabird folks - have you ever thought "*ANOTHER* talk about <species X>?!" So did we.

So we reviewed 3000 conference abstracts to see which species get the spotlight. Huge work from @ingridpollet.bsky.social with me and @seabirdsentinel.bsky.social

Climate‐Driven Increase in Transmission of a Wildlife Malaria Parasite Over the Last Quarter Century Climate warming is shaping ecosystems in several ways, and this includes changes in the dynamics of wildlife disease transmission. Over 26 years, avian malaria parasites have become much more common ...

Using historical samples from a long-term population of Bluetits we have shown that there has been an increase in malaria infected birds, from 45% in 1996 to around 90%in late 2020s. This increase in transmission is driven by warmer spring temp during the nestling phase.
