The whale shark ( Rhincodon typus ) is an iconic species in the Bird’s Head Seascape (BHS) in eastern Indonesia, yet little is known about its population and residency patterns across the region. This study documents the population demographics of this globally Endangered species from four key regions within the BHS: Cenderawasih Bay (CB), Kaimana (KA), Raja Ampat, and Fakfak. Using 13 years of photographic identification (pho...

Fish growth underpins individual fitness and population-level metrics, with fluctuations linked to environmental variability. Growth chronologies derived from otolith increment analysis are a powerful proxy to understand population responses to environmental change and productivity. Yet, long-term patterns of growth and their environmental drivers are better understood for shallow-water species compared to deep-water inhabitan...

Climatic variation can play a critical role in driving synchronous and asynchronous patterns in the expression of life history characteristics across vast spatiotemporal scales. The synchronisation of traits, such as an individual's growth rate, under environmental stress may indicate a loss of phenotypic diversity and thus increased population vulnerability to stochastic deleterious events. In contrast, synchronous growth und...

Latinas are less likely to receive genetic counseling and genetic testing (GCT) compared to non-Latina Whites because of systemic and patient-level barriers. We developed and tested fotonovelas to increase awareness of GCT among Latinas at-risk of hereditary breast and ovarian cancer (HBOC). Content for the fotonovelas was drawn from an existing culturally targeted narrative video focused on improving GCT use among Latinas at-...

Blue carbon ecosystems sequester and store a larger mass of organic carbon per unit area than many other vegetated ecosystems, with most being stored in the soil. Understanding the fine-scale drivers of variability in blue carbon soil stocks is important for supporting accurate carbon accounting and effective management of saltmarsh and mangrove habitats for carbon abatement. Here, we investigate the influence of local- and re...

Offshore platforms, subsea pipelines, wells and related fixed structures supporting the oil and gas (O&G) industry are prevalent in oceans across the globe, with many approaching the end of their operational life and requiring decommissioning. Although structures can possess high ecological diversity and productivity, information on how they interact with broader ecological processes remains unclear. Here, we review the curren...

This study examined thermally driven changes in swimming performance and aerobic metabolism ( Q 10 and aerobic scope of activity) of adult King George whiting Sillaginodes punctatus to the coldest (16° C) and the warmest (26° C) temperature encountered by this species. Compensation of aerobic scope, higher maximal swimming speeds and a maintained capacity to repay oxygen debt indicate that this species is capable of thermal ac...

Quantifying the elemental composition of elasmobranch calcified cartilage (hard parts) has the potential to answer a range of ecological and biological questions, at both the individual and population level. Few studies, however, have employed elemental analyses of elasmobranch hard parts. This paper provides an overview of the range of applications of elemental analysis in elasmobranchs, discussing the assumptions and potenti...

Common carp, Cyprinus carpio L., a destructive invasive pest of the Murray–Darling Basin, Australia, move from rivers into wetlands to spawn, making them vulnerable to trapping, but traps may also capture and affect access for native species. This study trialled a trap designed to separate carp from native fish entering wetlands by exploiting their different jumping and pushing behaviours. Trials were conducted at a flow‐throu...

This study quantified the per cent contribution of water chemistry to otolith chemistry using enriched stable isotopes of strontium ( 86 Sr ) and barium ( 137 Ba ). Euryhaline barramundi Lates calcarifer , were reared in marine (salinity 40), estuarine (salinity 20) and freshwater (salinity 0) under different temperature treatments. To calculate the contribution of water to Sr and Ba in otoliths, enriched isotopes in the tank...

A laboratory experiment was conducted to determine the interactive effects of temperature and diet on condition indices of juvenile black bream Acanthopagrus butcheri , reared for time periods ranging from 2 to 42 days. After fish were reared for varying periods, growth, morphometric (Fulton's K ) and biochemical [RNA:DNA (R:D) ratios] indices were measured. Fulton's K responded primarily to temperature, with progressive decre...

The southern garfish, Hyporhamphus melanochir (Val.), is an important inshore fishery species in South Australia. Over the past few years there have been concerns with this fishery, which is now considered to be over‐exploited. Currently, the fishery is assumed to consist of two separate stocks, but there is no understanding of movement patterns both within and between these two stocks to justify this assumption. Otolith chemi...

Ambient strontium:calcium (Sr:Ca) concentrations were determined at the temporal scales of months, weeks and days, in summer and winter at two estuarine sites, and experimentally derived correlations between ambient and otolith Sr:Ca were used to estimate the otolith Sr:Ca concentrations of ‘resident’ black bream Acanthopagrus butcheri . Wild black bream were collected in summer and winter at the end of the temporal water samp...
