Determine if each statement is correct or incorrect:1. Ecosystems with fewer numbers of species tend to be less stable.2. Increasing numbers of species lead to more redundancy which is bad for the ecosystem.3. More species mean more niche separation.4. Species with a low resistance will also have low resilience.5. Disturbances to ecosystems can be both naturally occurring and human caused.6. Stresses to ecosystems are useful for removing weaker species and ensuring the strongest survive.7. Bringing non-native species into an area to increase biodiversity makes the ecosystem more stable.

1) What makes an ecosystem resilient? 2) Explain the immediate and secondary effects of removing otters from a kelp forest ecosystem. (use the word: keystone species, biodiverse/biodiversity)
Match the approach to protection with the example from the academic literature. Species approach Hotspot approach Ecosystem approach 1. Wolf reintroductions into the Yellowstone environment restored riparian species and increased biodiversity because wolves controlled the numbers of elk and coyotes which allowed plants, beaver, and foxes to rebound (Ripple and Beschta 2003). 2. The creation of a reserve protects the red-brown treecreeper (Climacteris picumnus). This approach looks to accommodate processes that threaten species viability, such as fragmentation and feral predators (Nicholson et al. 2013). 3. Species richness of tiger beetles, Cicindelidae, is positively correlated with bird and butterfly diversity across North America, Australia, and the Indian subcontinent (Reid, 1998).

Determine if they are a keystone species. Then, write a one-page essay describing their role in their ecosystem.

Mimicry occured in nature as species tahe advantageous characteristics from other species to help them survive. As humans, we have also taken this idea of biomimicry and used nature as a design inspiration to sustainably solve human problems. some examples include: whale fins as wind turbines, shark skin materials for marine vessels and swimwear, burrs stick to animals and velcro, water collecting beetles and environmental application. Questions 1. Identify a real world challenge and think about potential designs to solve or help with this challenge. 2. research nature's models - what biomimicry can we see in nature for this challenge? 3. describe a model that could aid in the real world issue and have potential sustainable application.
