Here's a chance to get involved in some important #citizenscience.

If you spot any tagged Bogong moths over the next few weeks or months, report them to the Bogong Watch website (www.bogong.org) or record them on iNaturalist.

Not a first for Phillip Island on the ground. I have several observations from Phillip Island in January 2020 including this one observed January 12, 2020.

I would like to interrupt your doomscrolling for an important announcement: This figure from Ellen Dymit et al., 2025, depicts the proportion of vertebrate prey in felid scat, recorded as a Proportion of Occurrence (PoO). πŸ’©

Aussies urged to look for tiny white marking to solve years-long mystery of iconic creature Over the next two months, Aussies are being urged to do their part.

Help! If you are lucky enough to spot one of these bogong moths marked with a white sticker or paint, please report it.

Yep, they’re polymorphic for fruit colour. Some plants have yellow fruit, others pinky red.

Nine ways extreme events reshape river biodiversity How floods, droughts, heatwaves, and compound events are impacting life in rivers

Nine ways extreme events reshape #river #biodiversity

1. They cause selective mortality that erodes genetic diversity
2. Droughts fragment rivers and refuges can become ecological traps
3. Long‑lasting physical legacies reshape habitats

Spatial distribution of reproductive phenology observations in Australian subtropical rainforest flora for three time periods: (a) 1770–1970, (b) 1971–2000 and (c) 2001–2025. The mapped region spans from 21 to 35Β°S and 150 to 155Β°E.

PhD Chap1 done! With an all-star cast, I built a reproductive phenology dataset by integrating flowering and fruiting observations from as many sources as possible. The dataset covers: 255yrs, most Subtropical rainforests in Aus, and 915 species.

CLIMEX Match Climate Composite Match Index (CMI) overlaid with Tipuana tipu distribution location records, projected globally. Insets show the native range, part of South America, part of southern Africa, southwest Australia, and an area of eastern Australia with high levels of cultivation and/or naturalisation. Areas with an orange-red colour (CMI 0.8–1) had high CMI values. Areas with a blue colour (CMI 0.6–0.8) had a climate with moderate CMI values. Records of T. tipu are shown as open circles. Pink circles represent records of plants within the native range. All other colours represent plant records in the non-native range, with purple representing cultivated plant records, yellow representing non-cultivated plant records, green representing records with both cultivated and non-cultivated plants and brown representing plant records where the cultivation status was indeterminate.

The interplay between climatic niche and spatial distribution can inform the management of non-native invasive species. Our findings reveal that the invasion risk for species with small geographic ranges may be greater than assumed.

This workshop is filling up fast, so register soon if you're intending to go. Come and find out about eco acoustics, the art of owl detecting, owl rescues and releases that we've been involved in, and much much more. Too much owls is not enough!

Boomerang made from mammoth tusk with 5 cm scale

A boomerang made from mammoth ivory, from ObΕ‚azowa Cave, Poland. Dating to around 40,000 years ago, the object was shaped and well-used, with signs of polish in the areas where a right-handed person would have handled and thrown it.
