This paper presents an analysis of extensive collections of free-living marine and estuarine nematodes from 5 sites on sandy beaches and estuarine mudflats in south-eastern Australia, comprising of up to 90 samples collected at each site over a 40-year period. The lowest number found was 57 species in 30 samples from Clyde River Estuary, and the maximum was 112 species in 76 samples from Broulee. Random Species Accumulation Cu...

Fall armyworm, Spodoptera frugiperda (Lepidoptera: Noctuidae) is an invasive and important pest of multiple crops including grains and vegetables. The moth was first detected in Australia in 2020 and has since established populations across the north of the continent with further spread expected. Surveys for parasites and pathogens impacting Australian fall armyworm populations were undertaken between 2020 and 2025. Here, we r...
