[Ti] Título:Growth performance and survival of larval Atlantic herring, under the combined effects of elevated temperatures and CO2.

[Ab] Resumo:In the coming decades, environmental change like warming and acidification will affect life in the ocean. While data on single stressor effects on fish are accumulating rapidly, we still know relatively little about interactive effects of multiple drivers. Of particular concern in this context are the early life stages of fish, for which direct effects of increased CO2 on growth and development have been observed. Whether these effects are further modified by elevated temperature was investigated here for the larvae of Atlantic herring (Clupea harengus), a commercially important fish species. Over a period of 32 days, larval survival, growth in size and weight, and instantaneous growth rate were assessed in a crossed experimental design of two temperatures (10°C and 12°C) with two CO2 levels (400 µatm and 900 µatm CO2) at food levels mimicking natural levels using natural prey. Elevated temperature alone led to increased swimming activity, as well as decreased survival and instantaneous growth rate (Gi). The comparatively high sensitivity to elevated temperature in this study may have been influenced by low food levels offered to the larvae. Larval size, Gi and swimming activity were not affected by CO2, indicating tolerance of this species to projected "end of the century" CO2 levels. A synergistic effect of elevated temperature and CO2 was found for larval weight, where no effect of elevated CO2 concentrations was detected in the 12°C treatment, but a negative CO2 effect was found in the 10°C treatment. Contrasting CO2 effects were found for survival between the two temperatures. Under ambient CO2 conditions survival was increased at 12°C compared to 10°C. In general, CO2 effects were minor and considered negligible compared to the effect of temperature under these mimicked natural food conditions. These findings emphasize the need to include biotic factors such as energy supply via prey availability in future studies on interactive effects of multiple stressors.

[Ab] Resumo:Politicians, government officials, business representatives, and nongovernmental climate activists all in various ways emphasize what they see as progress being made in the aftermath of the Paris Agreement, even if they continue to warn of the dire consequences of business as usual. Indeed, there is no lack of encouraging private and public sector initiatives on climate change. Some macro trends seem to be moving in the right direction, as well. But, closer scrutiny shows that these positive trends are still far from adding up to the necessary fundamental shift in the global energy economy. Furthermore, the public may greatly overestimate the advancement of renewable solar and wind energy technology, which contributes to a false sense of progress and lessens political urgency. Without determined and reinvigorated political leadership from the European Union (EU), there is little hope that necessary emission reduction goals to stay below 2 °C above preindustrial levels can be met. The EU has driven international climate policy from the beginning of climate negotiations, and there is unfortunately no other source of leadership in sight. It will require difficult political decisions to be taken sooner rather than later to force a much quicker domestic energy transition and to raise financing to help developing countries with their own energy transition and adaptation to a rapidly warming world.

[Ab] Resumo:Municipalities and cities face myriad challenges with regard to planning; decisions that will have long-standing consequences need to be made in the context of pressing present concerns, constrained budgets, and uncertainty about the future under climate changes. Compounding the challenge may be a lack of clear signals from the state and federal leadership on investment priorities. This paper contends that existing strategies from decision science can prove useful for local governments as they seek actions that are robust despite uncertain futures and broadly beneficial across sectors and time horizons. An illustrative example of decision making with scenario analysis demonstrates how a city can prioritize funding and elevate the baseline functionality of its infrastructure and the well-being of its residents, regardless of when and how climate hazards occur.

[Ti] Título:United States news media and climate change in the era of US President Trump.

[Ab] Resumo:The Donald J Trump administration's strategy to disengage and downplay the Paris Climate Agreement will likely result in a slight decrease in the already low levels of US news media global warming coverage. This is because significant limitations with the news media's ability to adequately cover climate change predated the administration. First, studies indicate that advertising interests and editors have always challenged journalists' abilities to adequately report on climate change issues. Instead of climate change stories, editors often prefer more sensational topics that garner higher ratings and approval with advertisers. Second, the journalistic norm of balance and the role of sourcing give climate skeptics exceptional media exposure, which creates a "false balance" or equivalency between skeptics and scientists. Third, the massive power and influence of the fossil fuel industry's public relations arm has also had a tremendous impact on public (mis)understanding of climate change. Fourth, a trend toward declining climate change coverage and "climate silence" in US media is developing. Media corporations have substantially eliminated the number of environmental journalists that cover climate change. The overall effect of these limitations distorts public understanding of climate change and delays potential government action. Moving away from a predominantly commercial media system to one with a substantial noncommercial component can improve US journalism, whereas using advertising to increase rates for environmentally unsound products and services may also help mitigate global warming.

[Ti] Título:Climate conditions, and changes, affect microalgae communities… should we worry?

[Ab] Resumo:Microalgae play a pivotal role in the regulation of Earth's climate and its cycles, but are also affected by climate change, mainly by changes in temperature, light, ocean acidification, water stratification, and precipitation-induced nutrient inputs. The changes and impacts on microalgae communities are difficult to study, predict, and manage, but there is no doubt that there will be changes. These changes will have impacts beyond microalgae communities, and many of them will be negative. Some actions are currently ongoing for the mitigation of some of the negative impacts, such as harmful algal blooms and water quality, but global efforts for reducing CO emissions, temperature rises, and ocean acidification are paramount for reducing the impact of climate change on microalgae communities, and eventually, on human well-being.

[Ti] Título:Impact of African traditional worldviews on climate change adaptation.

[Ab] Resumo:Recent studies show cultural worldviews are a key determinant of environmental risk perceptions; thus, they could influence climate change adaptation strategies. African traditional worldviews encourage harmony between humans and the environment through a complex metaphysical belief system transmitted through folklore, taboos, and traditional knowledge. However, African traditional worldviews hold a belief in traditional gods that was shown to have a low connectedness to nature and a low willingness to change. In Makueni District, Kenya, 45% of agropastoralists surveyed believed drought was god's plan and could not be changed. In contrast, traditional knowledge, which is shaped by African traditional worldviews, is often used to frame adaptive strategies such as migration, changing modes of production, and planting different crop varieties. Furthermore, traditional knowledge has been used as a complement to science in areas where meteorological data was unavailable. However, the role of African traditional worldviews on climate change adaption remains understudied. Hence, there is a need to systematically establish the influence of African traditional worldviews on climate change risk perception, development of adaptive strategies, and policy formulation and implementation. In this commentary, we discuss the potential impacts of African traditional worldviews on climate change adaptation. Integr Environ Assess Manag 2018;14:189-193. © 2018 SETAC.

[Ti] Título:Biochemical responses and accumulation patterns of Mytilus galloprovincialis exposed to thermal stress and Arsenic contamination.

[Ab] Resumo:Organisms in marine systems are exposed to multiple stressors that create a range of associated environmental and ecotoxicological risks. Examples of stressors include alterations related to climate change, such as temperature increase, and the exposure to pollutants arising from human activities. The present study evaluated the impacts of Arsenic exposure (1mg/L) and warming (21°C) in Mytilus galloprovincialis, acting alone and in combination. Our results demonstrated that both Arsenic exposure and warming induced oxidative stress and reduced mussels metabolism, with changes becoming more prominent with the exposure time and when mussels were exposed to both stressors in combination. Furthermore, results obtained showed higher As accumulation in organisms exposed to warming treatments. The present study showed that under warming scenarios, the negative impacts induced by As may be enhanced in ecologically and economically relevant bivalves, with potential impacts on population stocks due to increased sensitivity to pollutants, which may eventually result in biodiversity loss and socio-economic impacts.

[Ti] Título:Patterns in reef fish assemblages: Insights from the Chagos Archipelago.

[Ab] Resumo:Understanding the drivers of variability in the composition of fish assemblages across the Indo-Pacific region is crucial to support coral reef ecosystem resilience. Whilst numerous relationships and feedback mechanisms between the functional roles of coral reef fishes and reef benthic composition have been investigated, certain key groups, such as the herbivores, are widely suggested to maintain reefs in a coral-dominated state. Examining links between fishes and reef benthos is complicated by the interactions between natural processes, disturbance events and anthropogenic impacts, particularly fishing pressure. This study examined fish assemblages and associated benthic variables across five atolls within the Chagos Archipelago, where fishing pressure is largely absent, to better understand these relationships. We found high variability in fish assemblages among atolls and sites across the archipelago, especially for key groups such as a suite of grazer-detritivore surgeonfish, and the parrotfishes which varied in density over 40-fold between sites. Differences in fish assemblages were significantly associated with variable levels of both live and recently dead coral cover and rugosity. We suggest these results reflect differing coral recovery trajectories following coral bleaching events and a strong influence of 'bottom-up' control mechanisms on fish assemblages. Species level analyses revealed that Scarus niger, Acanthurus nigrofuscus and Chlorurus strongylocephalos were key species driving differences in fish assemblage structure. Clarifying the trophic roles of herbivorous and detritivorous reef fishes will require species-level studies, which also examine feeding behaviour, to fully understand their contribution in maintaining reef resilience to climate change and fishing impacts.

[Ti] Título:Atmospheric CO effect on stable carbon isotope composition of terrestrial fossil archives.

[La] Idioma:eng
[Ab] Resumo:The C/ C ratio of C plant matter is thought to be controlled by the isotopic composition of atmospheric CO and stomatal response to environmental conditions, particularly mean annual precipitation (MAP). The effect of CO concentration on C/ C ratios is currently debated, yet crucial to reconstructing ancient environments and quantifying the carbon cycle. Here we compare high-resolution ice core measurements of atmospheric CO with fossil plant and faunal isotope records. We show the effect of pCO during the last deglaciation is stronger for gymnosperms (-1.4 ± 1.2‰) than angiosperms/fauna (-0.5 ± 1.5‰), while the contributions from changing MAP are -0.3 ± 0.6‰ and -0.4 ± 0.4‰, respectively. Previous studies have assumed that plant C/ C ratios are mostly determined by MAP, an assumption which is sometimes incorrect in geological time. Atmospheric effects must be taken into account when interpreting terrestrial stable carbon isotopes, with important implications for past environments and climates, and understanding plant responses to climate change.

[Ab] Resumo:Directional climate change (global warming) is causing rapid alterations in animals' environments. Because the nervous system is at the forefront of animals' interactions with the environment, the neurobiological implications of climate change are central to understanding how individuals, and ultimately populations, will respond to global warming. Evidence is accumulating for individual level, mechanistic effects of climate change on nervous system development and performance. Climate change can also alter sensory stimuli, changing the effectiveness of sensory and cognitive systems for achieving biological fitness. At the population level, natural selection forces stemming from directional climate change may drive rapid evolutionary change in nervous system structure and function.
