Slight Advantage

Populations of Acropora cervicornis, one of the most important reef-building corals in the Caribbean, have been declining due to human activities and global climate change. This has prompted the development of strategies such as coral farms, aimed at improving the long-term viability of this coral across its geographical range. This study focuses on comprehending how seawater temperature (ST), and light levels (LL) affect the survival and growth of A. cervicornis fragments collected from three reefs in Culebra, Puerto Rico. These individuals were fragmented into three pieces of the similar sizes and placed in farms at 5, 8, and 12 m depth. The fragments, ST and LL were monitored for 11 months. Results show that fragments from shallow farms exhibit significantly higher mortalities when compared to the other two depths. Yet, growth at shallow farms was nearly 24% higher than at the other two depths. Corals grew fastest during winter, when temperature and LL were lowest, regardless of the water depth. Fragment mortality and growth origin were also influenced by reef origin. We conclude that under the current conditions, shallow farms may offer a slight advantage over deep ones provided the higher growth rate at shallow farms and the high fragment survival at all depths.

Based on the latest data, paper investigates the dynamics of global climate change and its impact on economic growth in the long-term. The notion of climate risk is considered. The main directions of climate risk management policies are analyzed aimed, first, at reducing anthropogenic greenhouse gas emissions through technological innovation and structural economic shifts; secondly, at adaptation of population, territories and economic complexes to the irreparable effects of climate change. The problem of taking into account the phenomenon of climate change in the state economic policy is put in the context of the most urgent tasks of intensification of long-term socio-economic development and parrying strategic challenges to the development of Russia.

Long Term Studies

Long-term studies have revealed population declines in fishes, amphibians, reptiles, birds and mammals. In birds, and particularly amphibians, these declines are a global phenomenon whose causes are often unclear. Among reptiles, snakes are top predators and therefore a decline in their numbers may have serious consequences for the functioning of many ecosystems. Our results show that, of 17 snake populations (eight species) from the UK, France, Italy, Nigeria and Australia, 11 have declined sharply over the same relatively short period of time with five remaining stable and one showing signs of a marginal increase. Although the causes of these declines are currently unknown, we suspect that they are multi-faceted (such as habitat quality deterioration, prey availability), and with a common cause, e.g. global climate change, at their root.

The Future

Assessment of nearshore response to climatic change is an important issue for coastal management. To predict potential effects of climate change, a framework of numerical models has been implemented which enables the downscaling of global projections to an eroding coastline, based on TOMAWAC for inshore wave propagation input into SCAPE for shoreline modelling. With this framework, components of which have already been calibrated and validated, a set of consistent global climate change projections is used to estimate the future evolution of an un-engineered coastline. The response of the shoreline is sensitive to the future scenarios, underlying the need for long term large scale offshore conditions to be included in the prediction of non-stationary processes.

The One

Coral reefs are highly productive marine ecosystems that harborahigh biodiversity. The forming organisms of these reefs are the scleractinian corals, which form symbiotic interactions with multiple microorganisms. One of the best known symbiotic interactions in these systems is the one established with the microalgae Symbiodinium. The microalgae produce through photosynthesis up to 90% of the energy required by the coral. On the other hand, Symbiodiniumreceives from the coral an appropriate niche, that protects Symbiodiniumfrom the external environment, from the competition with other organisms and predation; it also provides abundant nutrients produced by other coral symbiontshighlighting the bacteria. As well as this, multiple symbiotic interactions confer metabolic capabilities to corals, which have enabled their capacity to adapt to climate changes for millions of years. However, in recent decades coral reef ecosystems are being extensively decimated. Given the new characteristics of an environment with significant changes sometimes somewhat erratic, probably the interactions that initially provided ecological advantages to corals are no longer sufficient to overcome environmental adversities or that as a result of the changes generated in the environment. The diversity of microorganisms capable of interactions that can be formed with the few remaining microorganisms do not confer to the coral, sufficient adaptative advantages to face the challenge of climate change. In this essay, we argue about the possibility that a decrease in the stock of microorganisms capable of interacting with corals, as a result of marine pollution, is a cause of the loss of biological aptitude of corals to survive in the current global climate change.

The Voice

While the importance of including diverse perspectives in museum programming has received considerable attention in the cultural realm, the same cannot be said for environmental science topics. In science and natural history museums, exhibitions on issues such as global climate change and loss of biodiversity are frequently narrowly defined in relation to an equally narrow perception of what constitutes environmental science. Because the facts of science in museums are still largely told by science curators, the voices of non-scientists are largely absent on such issues. As museum professionals, we must work to ensure that a diversity of perspectives is represented on environmental issues in our museums and on the capacity of our publics to participate in the presentation of environmental topics. We must support the public’s collective “power-to” (as John Holloway has termed it) have a voice in environmental programming.

Peatland ecosystems are characterized by a substantial accumulation of organic matter in soil (peat), resulting from long-term excess of net primary production at the surface compared to decomposition throughout the peat column. Globally, peatlands cover 3–4 percent of the earth’s land surface, yet they store 25–30 percent of the world’s soil carbon (about 455 Pg of C) and 9–16 percent of the world’s soil nitrogen (8–15 Pg of N) in peat. These large stores of C and N are especially vulnerable to global climate change. Although peatlands occur from the tropics to the Arctic, it is in the boreal region where peatlands are most abundant. The presence of a well-developed ground layer of mosses along with either abundant shrubs or sedges makes the population and community ecology of these ecosystems interesting and challenging. The high water table, presence of anoxia, and isolation from all nutrient inputs—except the atmosphere in some peatlands (bogs)—present unique opportunities to study the hydrology and biogeochemistry.
