Quantifying the ecological role of crocodiles: a 50-year review of metabolic requirements and nutrient contributions in northern Australia.

The ecological roles of large predators are well recognized, but quantifying their functional impacts remains an active area of research. In this study, we examined the metabolic requirements and nutrient outputs of the estuarine crocodile population () in northern Australia over a 50-year period, during which the population increased from a few thousand to over 100 000 individuals. Bioenergetic modelling showed that during this period, the crocodile population's annual prey consumption increased from <20 kg km in 1979 to approximately 180 kg km in 2019.

High intensity exercise programme in patients with hypertrophic cardiomyopathy: a randomized trial.

Background And Aims: The feasibility and impact of high intensity exercise programmes in patients with hypertrophic cardiomyopathy (HCM) are unknown. This study was conducted to determine the feasibility of a high intensity exercise programme and explore safety and efficacy outcomes in patients with HCM.

Methods: Participants were randomized to a 12-week supervised exercise programme (n = 40) in addition to usual care, or usual care alone (n = 40).

Drug Survival of Biological Therapies in Smokers and Non-Smokers With Psoriasis: A Retrospective Cohort Study Using Data From the Australasian Psoriasis Registry.

Background: Smoking is a modifiable risk factor that increases the likelihood of developing psoriasis and the severity of the disease. In recent years, biological therapies have transformed the management of psoriasis. There is conflicting evidence about whether smoking affects the efficacy of biologics.
