ABSTRACT Ecosystem monitoring is fundamental to our understanding of how ecosystem change impacting natural resources and vital for developing evidence‐based policy management. However, the different types monitoring, along with their recommended applications, are often poorly understood contentious. Varying definitions strict adherence a specific type can inhibit effective leading poor program development, implementation outcomes. In an effort develop more consistent clear programs, we here...
Predictions of how vegetation responds to spatial and temporal differences in climate rely on established links with plant functional traits types that can be encoded into Dynamic Global Vegetation Models. Individual have been linked at species level community within regions. However, a recent global assessment aggregated found unexpectedly weak macroclimate, bringing question broadscale trait–climate associations implicating local-scale environmental the filtering communities. To further...
Shark resource-use strategies affect how they will respond to changes within their environment and, as such, may be important consider in conservation and management. Movement data on sharks that use nearshore areas is particularly valuable because these habitats are highly dynamic. The present study used passive acoustic telemetry examine the space-use, habitat-selection habitat-specialisation patterns of Australian sharpnose shark, Rhizoprionodon taylori, a area. Habitat selectivity...
Shark dietary patterns can determine how they will respond to changes in prey availability and biodiversity. Geographic variation diet also indicate if species have unique structuring roles or feeding strategies different environments. Unfortunately, little is known about the of most shark varies over time space. This study used stable isotope analysis assess Australian sharpnose (Rhizoprionodon taylori). Plasma muscle δ 13 C 15 N R. taylori were compared with baselines from multiple...
Abstract Context Maps of C 3 and 4 plant abundance stable carbon isotope values (δ 13 C) across terrestrial landscapes are valuable tools in ecology to investigate species distribution exchange. Australia has a predominance -plants, thus monitoring change :C cover δ is essential national management priorities. Objectives We applied novel combination field surveys remote sensing data create maps Australia, vegetation isoscape for the continent. Methods used land-use rasters categorize...
This study used stable‐isotope analysis to define the nearshore regional residency and movements of small‐bodied Australian sharpnose shark Rhizoprionodon taylori . Plasma muscle δ 13 C 15 N R. were collected from across five embayments compared with values seagrass plankton each bay. Linear distances between adjacent bays ranged 30 150 km. There was a positive geographic correlation tissue environmental values. Populations highest that had These results suggest did not forage more than 100...
Abstract Questions Niche complementarity is often invoked to explain co‐existence between native and alien plant species in grasslands. However, positive correlations diversity observed recent studies could mask the displacement of particular functional groups or negative effects species. We asked: do alter composition proportions growth forms grasslands? Do decrease diversity? Location South Australian Methods performed RDA ordination on form abundances Hellinger‐transformed obtained from...
The photosynthetic pathway of plants is a fundamental trait that influences terrestrial environments from the local to global level. distribution different pathways in Australia expected undergo substantial shift due climate change and rising atmospheric CO2; however, tracking hindered by lack data on species, as well their relative cover within plant communities. Here we present for 2428 species recorded across 541 plots surveyed Australia's Terrestrial Ecosystem Research Network (TERN)...
Abstract The Terrestrial Ecosystem Research Network (TERN), Australia's national land ecosystem monitoring programme, measures critical environmental attributes from local to continental scale and generates quality data for research management. Since 2011, TERN has performed standardised field surveys sampling across a plot network. At each plot, records vegetation structure, composition diversity, soil characteristics, collects plant samples analysis. the time of submission, established...
Although parasite habitat preference is well studied, it rarely rigorously evaluated statistically because of many zero intensities. Attachment-site and intensities 2 macroectoparasite species (Caligus elongatus Calliobdella vivida) Atlantic sturgeon, Acipenser oxyrinchus Mitchill, in Minas Basin, Bay Fundy, Canada, were characterized with the use zero-inflated negative binomial statistical models that included a fork-length offset to control for body size. Three other parasites encountered,...
Biogeochemical maps of coastal regions can be used to identify important influences and inputs that define nearshore environments biota. tracers also track animal movement their diet, monitor human development, evaluate the condition habitats species. However, beneficial applications spatial biogeochemical analysis are hindered by a limited understanding how tracer distribution is affected different land ocean-based influences. To help address these knowledge gaps, we determined trends three...
Abstract In an era of unprecedented ecological upheaval, monitoring ecosystem change at large spatial scales and over long‐time frames is essential endeavor effective environmental management conservation. However, economic limitations often preclude revisiting entire networks high frequency. We aimed here to develop a prioritization strategy for select subset existing sites that meets the principles complementarity representativeness whole reality, maximizes (species accumulation)...
The movement and habitat use patterns of medium-bodied nearshore sharks are poorly understood. However, these species face some the highest levels exposure to anthropogenic development. space strategies exhibit affect their role within communities how they respond environmental change. present study used passive acoustic telemetry evaluate residency, use, creek whaler Carcharhinus fitzroyensis in a embayment Queensland, Australia. Individuals were monitored for approximately 18 months. Half...
Environmental monitoring data is fundamental to our understanding of environmental change and vital evidence-based policy management. However, different types ecological monitoring, along with their applications, are often poorly understood contentious. Varying definitions strict adherence a specific type can inhibit effective leading poor program development, implementation, outcomes. In an effort develop more consistent clear programs we review previous classifications support the...

Numerous studies have analysed the relationship between C4 plant cover and climate. However, few examined how different taxa vary in their response to climate, or environmental factors alter C4:C3 abundance. Here we investigate (a) proportional richness (relative C3) responds changes climate local factors, (b) if this is consistent among families. Proportional of species were determined at 541 one-hectare plots across Australia for 14 most common abundant families regressed against...
Abstract Plant communities are dynamic: cyclical, directional and stochastic changes in species composition make interpretation of responses complex. The multi-dimensionality ecological change is reduced by ecosystem indicators that quantify functional to environmental drivers. However, thresholds detectable may vary or the spatial configuration monitoring sites within regions. We quantified power a continental terrestrial plot network (TERN Ausplots, Australia) detect linked disturbance...
Recently discovered fossils from Naracoorte Caves have enabled reconstruction of the local palaeovegetation region and improved understanding floristic changes that occurred during Quaternary. Here, we describe taxa represented by macrofossils vegetative remains extracted Robertson Cave sediment deposit, approximately 820–24,230 years BP. Three non-angiosperm (Racopilum cuspidigerum var. convalutaceum, Pteridium esculentum Callitris sp.) five angiosperm (Allocasuarina verticillata, Hibbertia...
