Illegal wildlife trade is often male dominated at harvest, yet women’s roles across supply chains are under-examined. This study adds substantially to this growing body of knowledge drawing on 112 semi-structured interviews with law enforcement and illegal wildlife trade experts in South Africa, Hong Kong, and Canada. We show women participate in finance and money laundering, brokerage, logistics, retail, online marketing, and...
The shear capacity of hollow core bolts is still unclear due to the lack of experimental data. Therefore, to address this limitation, in this paper, the shear strength of three different types of hollow core bolts, including “X”, “S”, and “E” grade bolts, were studied experimentally using the double shear testing method under competent rock conditions. The outcomes of this research revealed that the shear force depended on the...
Rational Rodent EEGs display 7–12 Hz oscillations called spike-wave discharges (SWDs) that are more abundant with age, and some data suggest that they might interfere with hippocampus-dependent memory processing. Objective To test whether SWD activity contributes to the memory decline reported in aged rats. Methods Spatial learning was assessed in young and aged Long-Evans (LE) rats using a water maze protocol where aged rats...
Uncovering the Calls of Data‐Deficient Masked Owls Using Morphology and Environmental GradientsNARA Subscribed
Aim To test whether vocal characteristics of little‐known and ‘lost’ owl species can be inferred from environmentally driven morphological and vocal correlations, using the Australian Masked Owl ( Tyto novaehollandiae ) as a model system. Location Australasia. Taxon Australian Masked Owl ( T. novaehollandiae superspecies, Tytonidae). Methods We fit linear models to examine the relationship between environmental variables (lati...
Quantifying intra-urban socio-economic and environmental vulnerability to extreme heat events in Johannesburg, South AfricaNARA Subscribed
Urban populations face increasing vulnerability to extreme heat events, particularly in rapidly urbanising Global South cities where environmental exposure intersects with socioeconomic inequality and limited healthcare access. This study quantifies heat vulnerability across Johannesburg, South Africa, by integrating high-resolution environmental data with socio-economic and health metrics across 135 urban wards. We examine ho...
We examined the age and growth of the Pacific goliath grouper ( Epinephelus quinquefasciatus ) from 210 samples collected from the main fish markets in Panama and Colombia. Ages from otoliths ranged from young‐of‐the‐year to 13 years, predominantly between 1 and 4 years. The von Bertalanffy growth parameters were L∞ = 207 cm, k = 0.13 year −1 and t 0 = −1.87 years. Instantaneous mortality rates ( Z ) were estimated at 36% in C...
Marine species and associated fisheries demonstrate complex spatial dynamics driven by biological, ecosystem and socioeconomic factors and integrating these spatial dynamics into stock assessment models can improve fishery management advice. While preliminary good practices for developing spatial stock assessment models have been proposed, comprehensive demonstrations applying these practices remain limited. Drawing on these g...
Sex‐specific variation in population demography and life‐history traits (e.g., growth, natural mortality) is common in many fish populations. Differences in these processes by sex can dictate population dynamics and influence how harvesters interact with the resource. Across various fisheries management systems, stock assessment models (SAMs), which mathematically represent population age and/or size structure, are widely util...
An Effective Barrier Coating Technology Against Premature Bolt Failures in Underground MinesNARA Subscribed
Significant safety and economic consequences accompany the premature failure of bolts, posing sustainability challenges for mining operations. Previous studies have indicated that hydrogen-induced stress corrosion cracking (HISCC), primarily influenced by microbial activities termed microbiologically influenced stress corrosion cracking (MISCC), stands as a major contributor to the premature failure of bolts in underground min...
Characterisation of autophagy induction by the thiopurine drugs azathioprine, mercaptopurine and thioguanine in THP-1 macrophagesNARA Subscribed
Activating autophagy may be therapeutically beneficial, and we have previously shown that azathioprine (AZA), an immunomodulatory drug, induces autophagy. Here, we evaluated the induction of autophagy by the thiopurines AZA, mercaptopurine (6-MP) and thioguanine (6-TG) in THP-1 macrophages and investigated the mechanism of action in the context of this cellular process. The cytotoxicity of thiopurines was evaluated using an LD...
Determining the axial load transfer mechanism of rock bolts under various conditions is paramount for ensuring efficient reinforcement in rock structures, advancing our understanding of rock support and ability to design robust engineering solutions. This paper presents the results of an experimental study aimed at investigating the factors affecting axial load transfer mechanisms in fully encapsulated rock bolts including emb...
Global Marine Flyways Identified for Long‐Distance Migrating Seabirds From Tracking DataNARA Subscribed
Aim To identify the broad‐scale oceanic migration routes (‘marine flyways’) used by multiple pelagic, long‐distance migratory seabirds based on a global compilation of tracking data. Location Global. Time Period 1989–2023. Major Taxa Studied Seabirds (Families: Phaethontidae, Hydrobatidae, Diomedeidae, Procellariidae, Laridae and Stercorariidae). Methods We collated a comprehensive global tracking dataset that included the mig...
