Sequencing of 16S rRNA genes has become a powerful technique to study microbial communities and their responses towards changing environmental conditions in various ecosystems. Several tools have been developed for the prediction functional profiles from gene sequencing data, because numerous questions ecosystem ecology require knowledge community functions addition taxonomic composition. However, accuracy these relies on information derived genomes available public databases, which are...

Gendered and racial inequalities persist in even the most progressive of workplaces. There is increasing evidence to suggest that all aspects employment, from hiring performance evaluation promotion, are affected by gender cultural background. In higher education, bias has been posited as one reasons why few women make it upper echelons academic hierarchy. With unprecedented access institution-wide student survey data a large public university Australia, we investigated role conscious or...

Extensive development and construction in marine coastal systems is driving a phenomenon known as “ocean sprawl”. Ocean sprawl removes or transforms habitats through the addition of artificial structures some most significant impacts are occurring sedimentary environments. Marine sediments have substantial social, ecological, economic value, they rich biodiversity, crucial to fisheries productivity, major sites nutrient transformation. Yet impact ocean on environments has largely been...

Summary In this study, 454 pyrosequencing of the 16 S r RNA gene was used to investigate sediment bacterial community response contaminant disturbance across six estuaries with differing levels ‘modification’. We observed a significant influence metal and polycyclic aromatic hydrocarbon contaminants in shaping composition, structure diversity, metals being more influential contaminant. An abundant pervasive ‘core’ set bacteria found every sample were largely responsible for mediating...

ABSTRACT Anthropogenic disturbance is considered a risk factor in the establishment of non‐indigenous species (NIS); however, few studies have investigated role anthropogenic facilitating and spread NIS marine environments. A baseline survey native was undertaken conjunction with manipulative experiment to determine effect that heavy metal pollution had on diversity invasibility hard‐substrate assemblages. The study repeated at two sites each harbours New South Wales, Australia. sampled...

Oceania is a diverse region encompassing Australia, Melanesia, Micronesia, New Zealand, and Polynesia, it contains six of the world's 39 hotspots diversity. It has poor record for extinctions, particularly birds on islands mammals. Major causes include habitat loss degradation, invasive species, overexploitation. We identified major threatening processes (habitat climate change, overexploitation, pollution, disease) based comprehensive review literature each developed set conservation...

Global increases in urban development have resulted severe habitat modification many estuaries. Most are now dominated by artificial structures, which might a myriad of effects on native species. The provision extra hard substrata presents additional free space, and recent research suggests non-indigenous epifauna may be able to exploit these structures (particularly pontoons) more effectively than early fouling assemblages was compared settlement plates attached fixed or moving experimental...

Some ecosystems can undergo abrupt transformation in response to relatively small environmental change. Identifying imminent 'tipping points' is crucial for biodiversity conservation, particularly the face of climate Here, we describe a tipping point mechanism likely induce widespread regime shifts polar ecosystems. Seasonal snow and ice-cover periodically block sunlight reaching ecosystems, but effect this on annual light depends critically timing cover within solar cycle. At high...

Natural systems are increasingly being modified by the addition of artificial habitats which may facilitate invasion. Where invaders able to disperse from habitats, their impact spread surrounding natural communities and therefore it is important investigate potential factors that reduce or enhance invasibility. We surveyed distribution non-indigenous native invertebrates algae between reefs in a marine subtidal system. also deployed sandstone plates as experimental ‘reefs’ manipulated...

Summary Ecosystem functioning underpins the ecosystem services upon which humans rely. Critical functions, such as primary and secondary productivity, are, however, increasingly threatened by a range of anthropogenic stressors. Although extent threat contamination is large has been increasing, pollution one least‐studied stressors in ecology. We did systematic review critical synthesis effects contaminants on marine estuarine functioning. No other besides toxic chemicals were included this...

Abstract Aim Topographic complexity is widely accepted as a key driver of biodiversity, but at the patch‐scale, complexity–biodiversity relationships may vary spatially and temporally according to environmental stressors mitigates, species richness identity potential colonists. Using manipulative experiment, we assessed spatial variation in patch‐scale effects on intertidal biodiversity. Location 27 sites within 14 estuaries/bays distributed globally. Time period 2015–2017. Major taxa...
