The document discusses the complexity in predicting coral reef responses to climate stressors like temperature and ocean acidification. It presents two models examining community interactions and biochemical feedbacks between corals and the environment. Scenarios altering the stress impacts on different species showed predictions are sensitive to uncertainties. Biogeochemical coupling between corals and water further complicates predictions. The conclusion is that simple projections of reef responses to climate change are dangerous, and more studies considering multiple stressors and species are needed.
impactos del cambio climatico en ecosistemas costerosXin San
Anthropogenically induced global climate change has profound implications for marine
ecosystems and the economic and social systems that depend upon them. The
relationship between temperature and individual performance is reasonably well
understood, and much climate-related research has focused on potential shifts in
distribution and abundance driven directly by temperature. However, recent work has
revealed that both abiotic changes and biological responses in the ocean will be
substantially more complex. For example, changes in ocean chemistry may be more
important than changes in temperature for the performance and survival of many
organisms. Ocean circulation, which drives larval transport, will also change, with
important consequences for population dynamics. Furthermore, climatic impacts on one
or a few leverage species may result in sweeping community-level changes. Finally,
synergistic effects between climate and other anthropogenic variables, particularly fishing
pressure, will likely exacerbate climate-induced changes. Efforts to manage and conserve
living marine systems in the face of climate change will require improvements to the
existing predictive framework. Key directions for future research include identifying key
demographic transitions that influence population dynamics, predicting changes in the
community-level impacts of ecologically dominant species, incorporating populations
ability to evolve (adapt), and understanding the scales over which climate will change and
living systems will respond.

Modelling climate change impacts on nutrients and primary production in coast...Marco Pesce
There is high confidence that the anthropogenic increase of atmospheric greenhouse gases (GHGs) is causing modifications in the Earth's climate. Coastal waterbodies such as estuaries, bays and lagoons are among those most affected by the ongoing changes in climate. Being located at the land-sea interface, such waterbodies are subjected to the combined changes in the physical-chemical processes of atmosphere, upstream land and coastal waters. Particularly, climate change is expected to alter phytoplankton communities by changing their environmental drivers (especially climate-related), thus exacerbating the symptoms of eutrophication events, such as hypoxia, harmful algal blooms (HAB) and loss of habitat. A better understanding of the links between climate related drivers and phytoplankton is therefore necessary for projecting climate change impacts on aquatic ecosystems. Here we present the case study of the Zero river basin in Italy, one of the main contributors of freshwater and nutrient to the salt-marsh Palude di Cona, a coastal water body belonging to the lagoon of Venice. To project the impacts of climate change on freshwater inputs, nutrient loadings and their effects on the phytoplankton community of the receiving waterbody, we formulated and applied an integrated modelling approach made of: climate simulations derived by coupling a General Circulation Model (GCM) and a Regional Climate Model (RCM) under alternative emission scenarios, the hydrological model Soil and Water Assessment Tool (SWAT) and the ecological model AQUATOX. Climate projections point out an increase of precipitations in the winter period and a decrease in the summer months, while temperature shows a significant increase over the whole year. Water discharge and nutrient loads simulated by SWAT show a tendency to increase (decrease) in the winter (summer) period. AQUATOX projects changes in the concentration of nutrients in the salt-marsh Palude di Cona, and variations in the biomass and species of the phytoplankton community.

practical exercises, debates, discussions and presentations. Attendance at all tutorials is
compulsory and attendance at all lectures is highly recommended. To enter this subject you
should have completed Marine Biology to second year level. There are no inadmissible subject
combinations.
1.1 WHY MARINE CONSERVATION BIOLOGY?
So you have chosen to do Marine Conservation Biology! Congratulations on your wise choice.
There is an urgent need to focus science and research on conservation issues in the marine
environment. Many marine ecosystems are on the verge of collapse, many habitats have been
decimated and many believe we are on the threshold of a human-induced mass extinction event.
The mission of this subject is to develop scientific skills and enhance employment prospects to
confront the biodiversity crisis in the marine environment.
Conservation biology is the application of scientific methodology to the conservation of biological
diversity. It is an ecological science that targets the causes and seeks remedies to the disastrous
global decline in biodiversity that we have already seen on land and are beginning to see in our
harbours and oceans. Marine conservation biology is a relatively new and rapidly changing
discipline in marine biology. New concepts are devel.

Miriam Kastner: Her findings on METHANE HYDRATES in Ocean Acidification Summ...www.thiiink.com
Atmospheric carbon dioxide (CO2) levels are rising as a result of human activities, such as fossil fuel burning, and are increasing the acidity of seawater. This process is known as ocean acidi cation. Historically, the ocean has absorbed approximately 30% of all CO2 released into the atmosphere
by humans since the start of the industrial revolution, resulting in a 26% increase in the acidity of the ocean1.
Ocean acidi cation causes ecosystems and marine biodiversity to change. It has the potential to affect food security and it limits the capacity of the ocean to absorb CO2 from human emissions. The economic impact of ocean acidi cation could be substantial.
Reducing CO2 emissions is the only way to minimise long-term, large-scale risks.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

14. Indirect ecological interactions
•Example:
Reversing the effect of climate- related stress on macroalgae from being positive to negative had no influence on system behavior.
Contrast, the system was highly sensitive to a change in the stress upon herbivorous fishes.

(Céspedes Valcárcel 1995). Revista Cubana de Medicina Militar
19. Two Qualitative Models
•Incorporating the community level interactions between the species of interest and other benthic species.
Stressor include: elevated temperatura + ocean acidification
•Incorporating biochemical feedbacks that allow organisms to modify the stress environment that they experience.

•The Adjoint metrics number and direction of complementary feedback (J/I)
•The weighted metrics quantifies the ambiguity of this prediction
Evaluating the ratio of feedbacks of the opposing sign between I and j.
21.
22. Scenario
•First issue:
Alter individual components of the model by neutralising the effects of stress on corals
Scenario C = the effects of stress on corals
Scenario E = the effects of stress on fishes
Scenario G = the effects of stress on macroalgae, from positive to negative
•Second issue:
Simplifying one of the benthic interactions.
Scenario B y L = removing the effect of macroalgae on zoanthids
23. Scenario
•Third issue:
Created biogeochemical feedbacks between the benthos and overlying water column.
Scenario I = alleviating the acidification stress upon corals and fishes
Scenario k = added a second feedback such that coral calcification reduced aragonita.
Scenario L = removed the link between macroalgae and zoanthids
24.
25. Result
•The predictions of the effect of stress at the community level are very sensitive to the uncertainties of the impact of stressors in different taxa.
•The existence of biogeochemical coupling between benthic and water column complicates predictions even in the simplest models.
26. Outcome
•Consequences of uncertainties in predicting response of coral reefs to climate change.
How long events of increased temperature and pCO2 (partial pressure) influence on the physical and biogeochemical environmental experience of reef organisms?
28. New perspective
•32 years of daily temperature data
•Variation in temperature is greater at smaller scales of time (comparing daily and monthly with years)
•This would be useful, practical or reliable?
They propose a study of cloning corals and handling exposure as a function of the magnitude and variability of this exposure.
29. Other questions
•Sites with less variability in the frequency of thermal stress than seen in Heron Island have a higher risk for bleaching during abnormalities.
Combining the systematic analyze of stress responses with remote sensing data to predict the outcome of stress in different localities.
30. Ecological inheritance
•Construction of ecological niches generates ecological heritage.
•Corals are important ecosystem engineers.
This ecosystem is under strong selection pressure due to climate change.
Coral reef are excellent to test the theory of niche construction.
31. Conclusion
•It is very dangerous to make simple projections of the response of reefs to climate change, particularly on both a study of a single stressor and / or a limited number of species.
•Studies of coral stress face many challenges, but has a great potential for:
The development of "Evolutionary New Knowledge“
To create new ecological theories.
32. Discussion Questions
What do you think about the meta-analysis, and it effectiveness to investigate corals? In what other investigation camp it might be useful?
What do you think about the complexity in the study of coral reefs?
