Document Summary

The scientific study of life: in biology we ask and answer questions to understand the natural world. A theory is supported by a large usually growing body of evidence: test our predictions, designing experiments, collecting data, quantitative results. Example of the process of science from your book (and also from unc biology! Mimicry in north carolina snakes (mimicry - the similarity of one species to another. ) Lets apply what we have learned so far. Fill in the second table by matching a description from the first table (the column on the left) with a word from the column on the right in this table. The order of which these appear in your table should also be consistent with the process of science as you now know it! Some orca pods in the northeast atlantic eat fish, yet some pods prefer marine mammals.

Introduction and first body paragraph

------- exampler template with different topic

I. Introduction

Possible ideas for the introduction

Climate change

Process of OA

Somehow lead to SO

Thesis Statement : All organisms living bathed in an acidic environment will incur a metabolic cost as a result of the energy expended to maintain functioning cell chemistry this results in reduced growth and reproductive outputs. As a consequence population numbers will drop with a flow on reduction in overall ecosystem biomass and diversity.

II. Body

Main Point: OA has a metabolic cost for all marine organisms and affects growth, reproduction and nutrient value as a food source.[CA2]

Examples/Details/Explanations (include references (author, date)) :

Most pronounced in small organisms but is variable and dependant on pH

e.g. krill, gill & haemolymph regulation issues (Flores et al, 2012) ;

e.g. phytoplankton, reduced nutritional value;

e.g. shell forming organisms dissolution of CaCO₃ shells e.g. pteropods

Main Point: The metabolic cost on the individual results in lower numbers of individuals in a population.

Examples/Details/Explanations (include references (author, date)):

This cost results in reduced fertilisation, extended larval development time, deformities

e.g. seastar (Gonzalez-Bernat et al, 2014) detail effects at different pH levels;

e.g. urchin (Sewell et al 2014)

Main Point: A reduction in biomass of any one species has flow on effects up and down the food chain and could be especially pronounced in the unique Southern Ocean ecosystem.

Examples/Details/Explanations (include references (author, date)):

SO characterised by high nutrient low productivity, âwasp-waistâ structure and short food chains

e.g. phytoplankton as primary producers

e.g. krill as important food source

e.g. pteropods as nutrient cyclers

Main Point: Reduced food availability will likely alter interspecific interactions and may result in some species being driven to extinction.

Examples/Details/Explanations (include references (author, date)):

a. competition will increase as a result of less food e.g. between larger birds and mammals as a flow on from loss of krill

b. shell forming species will be at greater risk of predation due to weaker shells

c. e.g. seastars as keystone species maintaining diversity

III. Conclusion

Effects at organism level will impact on total biomass of that species and those that depend on it for food, therefore the overall productivity and biomass of the SO ecosystem will be reduced and loss of species diversity is expected.

Other Ideas to Conclude:

Effects growth and reproduction and is especially costly for shell forming organisms.

Will see changes as a result of effects on organisms with key functions within the SO ecosystem.

Ideas to leave the reader with (clincher):

Global significance of effects of OA on SO (something related to carbon sink and sequestering of Carbon) or perhaps reminding reader that OA is only one consequence of climate change and that organisms will also be at risk from rising sea temps, melting ice, and invasive species.
