Results

Did we notice any trends?

Clear, noticeable trends were found throughout the duration of this project where consistent increases in weight and length were shown clearly in our results.

As shown in the spreadsheet, a consistent increase in size and weight is clearly prevalent throughout the project.

Additionally, consistent casualties and abundance weekly, were brought up throughout the duration of the project.

Predictions

Throughout the duration of the project a noticeable trend of increase in mass and length (i.e. week 1 average of 2.74 cm, 0.028 g and week 7 average of 4.84 cm and 0.198 g respectively) is evident. This major increase proves further growth and development in future, highlighted by the life cycle, emphasising the the insects gradual increase in size/length overtime as they progress to adulthood.

Furthermore, as the calculated abundance shows random dispersion, it is clear the calculated mass and length may include discrepancies in the average results, influencing the overall growth. Meaning, despite results showing minimal increase, many insects have grown far beyond the average measurements. Additionally, as our insects develop and the process of natural selection occurs, the overall rate of growth will increase significantly. This is because the process of evolution will occur due to effects of global warming. Impacts of global warming are highlighted through research and data, showing evidence of mortality due to heat. Similarly, human impacts such as inadequate care directly impact their susceptibility to survival.

By considering abiotic and biotic factors and human impact we can closely predict future outcomes and theories, in relation to the development and evolution of our stick insect species. As global temperatures increase, the stick insects will be forced to adapt to withstand more diverse environments.

This is supported by our results:

Week 4 → 18°C = 2 deaths

Week 7 → 21°C = 0 deaths

Biotic factors such as plant life will also encourage adaptive changes required to suit various conditions, adversely influencing the consumers diet. The stick insect will have a more diverse diet as they try to adapt to other nutrient sources.

As humans start to demand more area, deforestation may occur destroying the ecosystems and environments necessary for the species survival. The stick insects will be forced to find a new home which they may not be suited to. Thus, causing competition for resources and predation, causing evolution.
