“…It is often suggested that extensive land use may effectively mitigate climate change effects due to higher (above- and below-ground) diversity and lower anthropogenic disturbance (Isbell et al, 2017; Oliver et al, 2016). Accordingly, we hypothesized the detrimental effects of climate change on soil microarthropods could be particularly strong in intensive land use, whereas they could be compensated by extensive land use.…”

“…Moreover, climate change effects on soil communities and their functions can be dependent on environmental contexts, such as different land-use regimes (De Vries et al, 2012; Foley et al, 2005; Walter et al, 2013). That is, intensively-used land characterized by higher levels of disturbance and lower biodiversity may be more vulnerable to climate change (Isbell et al, 2017), while extensively-managed land with less disturbance and higher biodiversity potentially mitigate these detrimental effects of climate change (Oliver et al, 2016). Therefore, disentangling the pathways by which these main environmental change drivers contribute to changes in the biomass of soil organisms and identifying potential interactive effects is crucial to better understand how ecosystem functions and services may be affected and could be maintained in the future.…”

“…Multiplicative antagonistic interactions occur when the combined effect is less than the additive threshold (Côté et al, 2016;Folt et al, 1999;Townsend et al, 2008). Illustrating and deconstructing the relative strength and direction of multiple pressure effects remains a challenge, especially across vast landscapes such as ecoregions, large freshwater river networks, or marine environments (Christensen et al, 2006;Halpern et al, 2015;Oliver, Dorrough, Doherty, & Andrew, 2016;Schinegger, Palt, Segurado, & Schmutz, 2016).…”

The expanding human global footprint and growing demand for freshwater have placed tremendous stress on inland aquatic ecosystems. Aichi Target 10 of the Convention on Biological Diversity aims to minimize anthropogenic pressures affecting vulnerable ecosystems, and pressure interactions are increasingly being incorporated into environmental management and climate change adaptation strategies. In this study, we explore how climate change, overfishing, forest disturbance, and invasive species pressures interact to affect inland lake walleye (Sander vitreus) populations. Walleye support subsistence, recreational, and commercial fisheries and are one of most sought‐after freshwater fish species in North America. Using data from 444 lakes situated across an area of 475 000 km2 in Ontario, Canada, we apply a novel statistical tool, R‐INLA, to determine how walleye biomass deficit (carrying capacity—observed biomass) is impacted by multiple pressures. Individually, angling activity and the presence of invasive zebra mussels (Dreissena polymorpha) were positively related to biomass deficits. In combination, zebra mussel presence interacted negatively and antagonistically with angling activity and percentage decrease in watershed mature forest cover. Velocity of climate change in growing degree days above 5°C and decrease in mature forest cover interacted to negatively affect walleye populations. Our study demonstrates how multiple pressure evaluations can be conducted for hundreds of populations to identify influential pressures and vulnerable ecosystems. Understanding pressure interactions is necessary to guide management and climate change adaptation strategies, and achieve global biodiversity targets.

“…Land use intensity is a semi-quantitative index 120 based on cultivation and grazing severity and age: so more intensively managed sites have 121 higher values (ranging between 0 and 12). More information on how these variables were 122 calculated and justified can be found in Oliver et al (2016). Critical thermal maximum and minimum assessments (CT max and CT min ) 132 CT max measurements were carried out in a Grant R4 waterbath with a GP200 heater using 133 distilled water.…”

Thermal stress is a key issue for species dominant within ecosystems especially those that carry out key ecosystem service roles. When assessing the impacts of climate change it is critical to assess its biotic impacts relative to other anthropogenic changes to landscapes including the reduction of native vegetation cover, landscape fragmentation and changes in land use intensity. Here we integrate the observed phenotypic plasticity of the dominant and ubiqitous meat ant Iridomyrmex purpureus in critical thermal limits across altitudinal, land cover and land use gradients to: (i) predict the adaptive capacity of a key terrestrial ecosystem service provider to changes in climate, land cover and land use, and (ii) assess the ability of multiple use landscapes to confer maximum resilience to terrestrial biodiversity in the face of a changing climate. The research was carried out along a 270km aridity gradient spanning 840m in altitude in northern New South Wales, Australia. When we assessed critical thermal maximum temperatures (CT max ) of meat ants in relation to the environmental variables, and within the model we had critical thermal minimums of meat ants (CT min ) as a random slope and as a fixed effect we detected a negative aridity effect on CT max , a negative effect of land use intensity, and no overall correlation between CT max and CT min . We also found a negative relationship with warming tolerance of I. purpureus and landscape aridity. In conclusion, we expect to see a reduction in the physiological resilience of I. purpureus as land use intensity increases and as the climate becomes more arid. Meat ants are key ecosystem engineers and as they are put under more stress, wider ecological implications may occur if populations decline or disappear.
