Final answer:
The SLOSS dilemma involves controversy over habitat fragmentation and preserve design, with arguments for creating either a single large preserve or several small preserves.
Step-by-step explanation:
The SLOSS dilemma involves controversy over habitat fragmentation and preserve design. The term SLOSS stands for Single Large or Several Small, referring to the debate whether to create a single, large habitat or several small habitats when designing nature preserves.
Advocates of the Single Large approach argue that it is better to have one large preserve because it can support a greater number and variety of species. On the other hand, proponents of the Several Small approach argue that several small preserves are more resilient against habitat loss and fragmentation, and can facilitate species movement.
For example, when planning a nature preserve, one option could be to create a large contiguous area, while another option could be to create several smaller pockets of protected habitats interconnected by corridors.
