Figures
Figure 1: What is Lessepsian Migration?
The migration of marine species along the Suez Canal
How many replicates were used?
5
What statistical test was used to determine the statistical significance for “Plant Performance”?
Anova
Where do seagrasses grow?
Shallow water sediment
What did the native populations lose under heat stress?
Lost number of shoots, reduced growth rate, and decreased leaf size
Figure 4: Why did the native species not recover in the recovery phase?
They were already exposed to 32 degrees Celsius so they stopped growing
What parts of the plant did they collect for the experiments?
the shoots, attached roots, and rhizomes
Which plants (invasive or native) performed better during the thermal stress experiment? Explain
invasive population because they have a higher thermal stress tolerance
Where are the native H.Stipulacea populations located?
Red Sea, the Persian Gulf, and the Indian Ocean
What are the experimental variables?
Temperature
Figure 5: What temperature did the native population have a reduction in protein content?
32°C
How far apart were each plant from each other and what was the depth?
They collected full plants at least 2m away from each other and each had a 4m depth
What is quantum yield and why was it used?
Quantum yield is a way of measuring the efficacy of the photosystem proteins and how much light energy goes in and is being used
What did the researchers hypothesize?
Hypothesis: Rising sea temperatures might affect seagrasses by changes in growth rates, sexual reproduction, and germination
What are the indirect and direct anthropogenic factors?
Indirect is the climate change and the direct is the quality of water decreasing and poor land use (pollution)
