Question

For which organisms were ex situ conservation measures used?

1) Loggerhead turtles
2) California condors
3) Nile perch
4) Zebra mussels

Answer 1

Ex situ conservation measures have been used for loggerhead turtles, California condors, and zebra mussels.

Step-by-step explanation:

Ex situ conservation measures were used for the following organisms:

1. Loggerhead turtles: Loggerhead turtle populations are often at risk due to habitat loss and accidental capture in fishing gear. Ex situ conservation measures include establishing protected areas, implementing nesting beach conservation programs, and rehabilitating injured turtles in specialized facilities.
2. California condors: California condors are critically endangered and have been the focus of intensive captive breeding and reintroduction efforts. Ex situ conservation measures for California condors include breeding them in captive breeding facilities, releasing captive-bred birds into the wild, and implementing monitoring and protection programs in their natural habitat.
3. Zebra mussels: Although zebra mussels are considered invasive species, ex situ conservation measures have been used to quantify their impact and develop strategies to prevent their spread. This includes studying their biology and ecology, monitoring their populations, and implementing control measures in affected areas.
