In the quest of isotope equilibrium for trophic discrimination estimation: diet–tissue dynamics in Nile crocodiles ( <i>Crocodylus niloticus</i> ) Open
Stable isotopes of carbon (δ13C) and nitrogen (δ15N) are increasingly employed to study the foraging ecology of ectothermic predators like crocodilians. However, accurate and precise estimations of trophic discrimination factors between di…

Seabirds Enhance Primary Producer and Consumer Isotope Signals on a Sub‐Tropical Island Open
Seabirds are long‐range transporters of nutrients, linking their marine feeding grounds with their terrestrial breeding and roosting sites. Seabirds can influence the terrestrial environment in which they reside by depositing nutrient‐rich…

Strength in numbers: Combining small pockets of opportunistic sampling for Australian seabird plastic ingestion Open
While the problem of plastic ingestion by wildlife is well recognised, it also suffers from a "file drawer" problem where small incidentally collected data remains unpublished because on its own, it may represent only a handful of individu…

Global extinction of Slender‐billed Curlew ( <i>Numenius tenuirostris</i> ) Open
In the current biodiversity crisis, conservation efforts are often focused on extinction prevention. However, it can be difficult to determine if a species is extinct, especially if the species has an extensive range, including being a tra…

Tactile bill-tip organs in seabirds suggest conservation of a deep avian symplesiomorphy Open
Birds’ bills are their main tactile interface with the outside world. Tactile bill-tip organs associated with specialized foraging techniques are present in several bird groups, yet remain understudied in most clades. One example is Austro…

The use of vibrational spectroscopy and supervised machine learning for chemical identification of plastics ingested by seabirds Open
Plastic pollution is now ubiquitous in the environment and represents a growing threat to wildlife, who can mistake plastic for food and ingest it. Tackling this problem requires reliable, consistent methods for monitoring plastic pollutio…

Long distance avian migrants fail to bring 2.3.4.4b HPAI H5N1 into Australia for a second year in a row Open
There is an ongoing and profound burden of lineage 2.3.4.4b high pathogenicity avian influenza (HPAI) H5N1 on wildlife and poultry, globally. Herein we report the continued absence of HPAI and antibodies against lineage 2.3.4.4b HPAI from …

The Colouration in Dicrurus caerulescens (White-bellied Drongo) Follows the Precipitation and Temperature of the Environment Open
The variation in climatic conditions over space and time is considered a major driving force in speciation. Gloger's rule is one such rule that broadly explains the variation in the colouration of endotherms (birds and mammals) with the ef…

Plastic pollution as a canvas for change: fostering collaboration for environmental solutions and actions through art and science Open
Meaningful action and engagement are needed in a time of rapid planetary change and biodiversity loss. They cannot be achieved through scientific outputs alone, and scientists are increasingly recognizing the need to work with a diverse ra…
