Liz likely concluded that the population declines in marine iguanas were influenced by environmental factors such as changes in food availability or habitat disruption.
Liz's conclusions about the cause of population declines in marine iguanas would likely be drawn from a comprehensive analysis of various factors impacting their environment. These could include changes in food availability, alterations in habitat conditions, or potential disruptions caused by human activities or climate change.
By conducting field surveys, monitoring ecological indicators, and analyzing historical data, Liz might have identified patterns and correlations that point to specific stressors affecting the marine iguana population. The conclusions would be based on a holistic understanding of the ecosystem, allowing Liz to pinpoint the factors contributing to the decline and inform conservation strategies to mitigate these threats and support the recovery of marine iguana populations.
