Patterns of environmental spatial structure lie at the heart most fundamental and familiar patterns diversity on Earth. Antarctica contains some strongest gradients planet therefore provides an ideal study ground to test hypotheses relevance variability for biodiversity. To answer pivotal question, “How does variation in physical biological properties across Antarctic drive biodiversity?” we have synthesized current knowledge terrestrial, freshwater, marine biomes related this observed...
Commercial fishing is one of the most important human impacts on marine benthic environment. One such impact through disturbance to habitats as gear (trawls and dredges) are dragged across seafloor. While direct effects an communities appear obvious, magnitude has been very difficult evaluate. Experimental fishing-disturbance studies have demonstrated changes in small areas; however, broader scale implications attributing these based long-term data considered equivocal. By testing a series...
The wider effects of fishing on marine ecosystems have become the focus growing concern among scientists, fisheries managers and industry. present review examines role habitat structure heterogeneity in ecosystems, (i.e. trawling dredging) these two components complexity. Three examples from New Zealand Australia are considered, where available evidence suggests that has been associated with degradation or loss through removal large epibenthic organisms, concomitant fish species which occupy...
An important ecological issue is developing an understanding of how patterns and processes vary with scale. We designed a field experiment to test differences in the aerial extent disturbance affected macrofaunal recolonization on sandflat. Three different plot sizes (0.203 $m 2 $, 0.81 3.24 $) were dafaunted, samples collected assess recovery over 9—mo period. As sandflat used for was prone by wind—driven waves, we also measured changes sediment bed height (an indicator stability) course...
Ocean acidification is a well recognised threat to marine ecosystems. High latitude regions are predicted be particularly affected due cold waters and naturally low carbonate saturation levels. This of concern for organisms utilising calcium (CaCO3) generate shells or skeletons. Studies potential effects future levels pCO2 on high calcifiers at present limited, there little understanding their acclimate these changes. We describe laboratory experiment compare physiological metabolic...
Important findings from the second decade of 21st century on impact environmental change biological processes in Antarctic were synthesised by 26 international experts. Ten key messages emerged that have stakeholder-relevance and/or a high for scientific community. They address (i) altered biogeochemical cycles, (ii) ocean acidification, (iii) climate hotspots, (iv) unexpected dynamism seabed-dwelling populations, (v) spatial range shifts, (vi) adaptation and thermal resilience, (vii) sea...
Ocean surface temperatures and the frequency intensity of marine heatwaves are increasing worldwide. Understanding how organisms respond adapt to heat pulses rapidly changing climate is crucial for predicting responses valued species ecosystems global warming. Here, we carried out an in situ experiment investigate sublethal spikes a functionally important intertidal bivalve, venerid clam Austrovenus stutchburyi. We describe changes metabolic under two warming scenarios (five days seven days)...

Predicting the dynamics of ecosystems requires an understanding how trophic interactions respond to environmental change. In Antarctic marine ecosystems, food web are inextricably linked sea ice conditions that affect nature and magnitude primary sources available higher levels. Recent attention on changing in polar seas highlights need better understand webs changes such broad-scale drivers. This study investigated importance advected structure benthic coastal Antarctica. We compared...
Studies of the influence small-scale disturbances on soft-bottom communities have usually been conducted one type community only.We utilized polychaete and bivalve dominated macrobenthic in 2 physically similar intertidal sandflat sites to study differences recolonization pits created by feeding eagle rays Myljobatis tenuicaudatus.In both ray were sampled 6 occasions until 12 d after their creation.Ray rapidly infilled with sediment grain size that surrounding sandflat.Organic carbon content...
Bedload and water column traps were used with simultaneous wind velocity measurements to study postlarval macrofaunal dispersal dynamics in Manukau Harbour, New Zealand. A 12‐fold range mean condition resulted large differences flow (12‐fold), sediment flux (285‐fold), trap collection of total number individuals (95‐fold), the dominant infaunal organism (84‐fold for bivalve Macomona liliana ), species (4‐fold). There very strong, positive relationships among condition, velocity, flux,...
Ecological and environmental variability in natural ecosystems precludes the widespread use of simplistic design analysis tools to detect effects human activities on ecosystems. BACI (Before–After Control–Impact) sampling is often recommended overcome problem inferring that changes are due an impact rather than variability. Using five different techniques (from nested ANOVA time-series intervention) data with spatial, temporal, at scales relevant assessments, we investigated how designs cope...
Land use can exacerbate the rate of sediment delivery to estuaries. In particular, for catchments with steep terrain and heavy, sporadic rainfall, changes in land increase risk catastrophic deposition terrestrial sediment. One key issues assessing ecological significance sedimentation events is determining recovery macrobenthic community understanding how physical biological processes influence different locations. We conducted a field experiment over 212 days assess impact deposits at six...

Linking the results of localized field experiments to generalities about role specific processes is essential in ecology. Comparative studies conducted at multiple locations enable general importance be assessed. However, spatial or temporal variation strength local ecological relationships frequently makes it difficult draw conclusions, as increasing extent a study likely increase physical and biological heterogeneity. To unravel influence differences wave climate on interactions among...
