Using dietary metabarcoding analyses to characterise waterbirds-agriculture interactions

Amelie Corriveau, Marcel Klaassen, Stephen Garnett, Mirjam Kaestli, Matthew Power, Mahsa Mousavi-Derazmahalleh, Megan Coghlan, Keith Christian, Michael Bunce & Hamish Campbell
Globally, the use of agricultural fields by waterbirds has increased, resulting in conflicts with farmers. Designing effective management strategies to resolve these conflicts requires understanding the species’ resource use. Dietary analyses can shed light on the extent of consumption of agricultural crops and surrounding natural resources, as well as the potential relationship between diet and an individual’s body condition and ultimately its fitness. We examined the dietary composition of the tropical magpie goose (Anseranas semipalmata),...

Missed Nursing Care in Australia: Exploring the Contributing Factors

Data for: Substantial intraspecific trait variation across a hydrological gradient in northern Australian fishes

Osmar Luiz, Julian Olden, Mark Kennard, David Crook, Michael Douglas, Thor Saunders, Dion Wedd, Brendan Adair & Alison King
Trait-based models of ecological communities and ecosystem functioning often fail to account for intraspecific variation in functional traits, assuming that intraspecific variability is negligible compared to interspecific variability. However, this assumption remains poorly tested across vertebrate animals where past studies routinely describe species according to mean trait values without explicit consideration of individual trait variability. We assessed nine functional traits for 4,254 individuals belonging to 15 freshwater fish species from 11 families in Northern Australia,...

Taxonomic revision reveals potential impacts of Black Summer megafires on a cryptic species

Chris Jolly, Harry Moore, Mitchell Cowan, Teigan Cremona, Judy Dunlop, Sarah Legge, Grant Linley, Vivianna Miritis, John Woinarski & Dale Nimmo
Context: Sound taxonomy is the cornerstone of biodiversity conservation. Without a fundamental understanding of species delimitations, as well as their distributions and ecological requirements, our ability to conserve them is drastically impeded. Cryptic species – two or more distinct species currently classified as a single species – present a significant challenge to biodiversity conservation. How do we assess the conservation status and address potential drivers of extinction if we are unaware of a species’ existence?...

Data from: Variation in red fox Vulpes vulpes diet in five continents

Irene Castañeda, Tim S. Doherty, Patricia A. Fleming, Alyson M. Stobo-Wilson, John C. Z. Woinarski & Thomas M. Newsome
Understanding variation in the diet of widely distributed species can help us to predict how they respond to future environmental and anthropogenic changes. We studied the diet of the red fox Vulpes vulpes, one of the world’s most widely distributed carnivores. We compiled dietary data from 217 studies at 276 locations in five continents to assess how fox diet composition varied according to geographic location, climate, anthropogenic impact and sampling method. The diet of foxes...

Diverse parentage relationships in paternal mouth-brooders

Janine Abecia, Alison King, Osmar Luiz, David Crook, Dion Wedd & Sam Banks
While mouthbrooding is not an uncommon parental care strategy in fishes, paternal mouthbrooding only occurs in eight fish families and little studied. The high cost of paternal mouthbrooding to the male implies a low risk of investment in another male’s offspring but genetic parentage patterns are poorly known for paternal mouthbrooders. Here we used single nucleotide polymorphism (SNP) genetic data to investigate parentage relationships of broods of two mouthbrooders of northern Australian rivers, mouth almighty...

C porosus genotype data

Yusuke Fukuda & Sam Banks
We collected 714 tissue samples of non-captive saltwater crocodiles Crocodylus porosus from Australia and its neighbouring countries and got them genotyped by Diversity Arrays Technology (Canberra, Australia) between 2016 and 2019. The folder contains two files named 'Report_DCroc19-4196_4_moreOrders_SNP_mapping_2.csv' and 'IDpop_sample_data_.csv'. The former contains the single-nucleotide polymorphism (SNP) data and latter has attributes (population ID, GPS coordinates, species, country) of each sample.

Dietary shifts may underpin the recovery of a large carnivore population

Mariana Campbell, Vinay Udyawer, Timothy Jardine, Yusuke Fukuda, R. Keller Kopf, Stuart Bunn & Hamish Campbell
Supporting the recovery of large carnivores is a popular yet challenging endeavour. Estuarine crocodiles in Australia are a large carnivore conservation success story, with the population having extensively recovered from past heavy exploitation. Here, we explored if dietary changes had accompanied this large population recovery by comparing the isotopes δ13C and δ15N in bones of crocodiles sampled 40 to 55 years ago (small population) with bones from contemporary individuals (large population). We found that δ13C...

Current flow files mapped by Omniscape representing the dispersal of saltwater crocodiles

Yusuke Fukuda & Sam Banks
This folder contains raster data in asc format to be used with Omniscape to visualise predicted flow across a study area raster, using the core breeding habitat cells ('Saltwater crocodile core breeding habitat cells.asc') for saltwater crocodiles (Crocodylus porosus) in the Northern Territory, Australia, the optimized resistance surface ('Saltwater crocodile optimized resistance surface.asc'), and core habitat cells ('Saltwater crocodile core habitat cells.asc') as ground nodes, effectively representing locations where current could ‘settle’.

Functional miscibility and thermomechanical properties enhancement of substituted phthalic acetylated modified chitin filler in biopolymer composite

Niyi Olaiya, O.S. Obaseki, Gaber A.M. Mersal, Mohamed M. Ibrahim, Mahmoud M. Hessien, Funmilayo Olaiya, Asif Afzal, Taslima Khanam & Ahmad Rashedi
The miscibility between hydrophobic and hydrophilic biopolymers has been of significant challenge. This study used a novel simplified chitin modification method to produce phthalic - chitin using phthalic anhydride in a substitution reaction. The FT-IR functional group analysis was used to confirm the substitution reaction. The modified chitin was used as compatibiliser in PLA/starch biocomposite to enhance its properties. The biocomposite was prepared using melt extrusion and compression moulding technique. The biocomposite's morphological, thermomechanical, and...

Counting the bodies: estimating the numbers and spatial variation of Australian reptiles, birds and mammals killed by two invasive mesopredators

Alyson Stobo-Wilson, Brett Murphy, Sarah Legge, Hernan Caceres-Escobar, David Chapple, Heather Crawford, Stuart Dawson, Chris Dickman, Tim Doherty, Patricia Fleming, Stephen Garnett, Matthew Gentle, Thomas Newsome, Russell Palmer, Matthew Rees, Euan Ritchie, James Speed, John-Michael Stuart, Andres Suarez-Castro, Eilysh Thompson, Ayesha Tulloch, Jeff Turpin & John Woinarski
Aim: Introduced predators negatively impact biodiversity globally, with insular fauna often most severely affected. Here, we assess spatial variation in the number of terrestrial vertebrates (excluding amphibians) killed by two mammalian mesopredators introduced to Australia, the red fox (Vulpes vulpes) and feral cat (Felis catus). We aim to identify prey groups that suffer especially high rates of predation, and regions where losses to foxes and/or cats are most substantial. Location: Australia Methods: We draw information...
