“…acidosis and metabolic depression) or elevated temperature (e.g. elevated metabolism and functional hypoxia), but less capable to maintain their homeostatic and growth function when exposed to both conditions (Melatunan et al 2009). Therefore, based on the evidence presented we predict that organisms will be detrimentally affected by the synergistic effects of decreased ocean pH and elevated temperature once these variables exceed the window for physiological tolerance of organisms (safety margin; Stillman 2002).…”

A mesocosm experiment was conducted to quantify the eff ects of reduced pH and elevated temperature on an intact marine invertebrate community. Standardised faunal communities, collected from the extreme low intertidal zone using artifi cial substrate units, were exposed to one of eight nominal treatments (four pH levels: 8.0, 7.7, 7.3 and 6.7, crossed with two temperature levels: 12 and 16 ° C). After 60 days exposure communities showed signifi cant changes in structure and lower diversity in response to reduced pH. Th e response to temperature was more complex. At higher pH levels (8.0 and 7.7) elevated temperature treatments contained higher species abundances and diversity than the lower temperature treatments. In contrast, at lower pH levels (7.3 and 6.7), elevated temperature treatments had lower species abundances and diversity than lower temperature treatments. Th e species losses responsible for these changes in community structure and diversity were not randomly distributed across the diff erent phyla examined. Molluscs showed the greatest reduction in abundance and diversity in response to low pH and elevated temperature, whilst annelid abundance and diversity was mostly unaffected by low pH and was higher at the elevated temperature. Th e arthropod response was between these two extremes with moderately reduced abundance and diversity at low pH and elevated temperature. Nematode abundance increased in response to low pH and elevated temperature, probably due to the reduction of ecological constraints, such as predation and competition, caused by a decrease in macrofaunal abundance. Th is community-based mesocosm study supports previous suggestions, based on observations of direct physiological impacts, that ocean acidifi cation induced changes in marine biodiversity will be driven by diff erential vulnerability within and between diff erent taxonomical groups. Th is study also illustrates the importance of considering indirect eff ects that occur within multispecies assemblages when attempting to predict the consequences of ocean acidifi cation and global warming on marine communities.

“…Wildfire severity is also a key predictor of debris‐flow risk in the western United States (Gartner et al., 2008 ; Miller et al., 2003 ; Staley et al., 2017 ). Higher severity fires alter soil hydraulic properties and expose bare soil, which tends to increase delivery of water and sediment to rivers following precipitation events (Melatunan et al., 2009 ; Moody & Martin, 2004 ; Robichaud et al., 2019 ).…”

Wildfires in many western North American forests are becoming more frequent, larger, and severe, with changed seasonal patterns. In response, coniferous forest ecosystems will transition toward dominance by fire‐adapted hardwoods, shrubs, meadows, and grasslands, which may benefit some faunal communities, but not others. We describe factors that limit and promote faunal resilience to shifting wildfire regimes for terrestrial and aquatic ecosystems. We highlight the potential value of interspersed nonforest patches to terrestrial wildlife. Similarly, we review watershed thresholds and factors that control the resilience of aquatic ecosystems to wildfire, mediated by thermal changes and chemical, debris, and sediment loadings. We present a 2‐dimensional life history framework to describe temporal and spatial life history traits that species use to resist wildfire effects or to recover after wildfire disturbance at a metapopulation scale. The role of fire refuge is explored for metapopulations of species. In aquatic systems, recovery of assemblages postfire may be faster for smaller fires where unburned tributary basins or instream structures provide refuge from debris and sediment flows. We envision that more‐frequent, lower‐severity fires will favor opportunistic species and that less‐frequent high‐severity fires will favor better competitors. Along the spatial dimension, we hypothesize that fire regimes that are predictable and generate burned patches in close proximity to refuge will favor species that move to refuges and later recolonize, whereas fire regimes that tend to generate less‐severely burned patches may favor species that shelter in place. Looking beyond the trees to forest fauna, we consider mitigation options to enhance resilience and buy time for species facing a no‐analog future.

Fouling communities from the South African west coast are vulnerable to cooling and ocean acidification

Changing temperature and ocean acidification are well-recognised consequences of climate change in marine systems. In contrast to global trends, the South African west coast is experiencing cooling due to increased frequency and intensity of upwelling. The implications of concurrent cooling and acidification for marine biota are poorly understood, particularly at the community level. This laboratory study assessed how cooling and acidification might affect fouling communities along the South African west coast. Communities were experimentally exposed to two temperatures, 13℃ (current) and 9℃ (cooling), and three pH treatments, 7.9 (current), 7.6 and 7.4, for 18 days. Cooling and acidification altered community structure. Species diversity declined in response to acidification but was not affected by cooling. This was driven by greatest loss of species at 7.4 pH. Notably, acidification reduced the abundance of both calcifying and soft-bodied taxa, highlighting the vulnerability of taxa like ascidians to acidification. Overall, these results highlight the dominant threat posed by acidification, even for alien taxa that are often perceived as resilient to climate change. Additionally, in regions experiencing cooling, acidification may pose a greater threat to fouling communities than thermal changes.
