Which of the following is a generally accurate statement about the current research regarding forest fragmentation?

#Unit 9. Diversity of Life Forms

  1. Fragmented forests promote biodiversity because they result in the combination of forestedge species and forest-interior species.

  2. In fragmented forests, the number of forested-adapted species tend to decline and the number of edge species tend to increase.

  3. Fragmented forests are the goal of conservation biologists who design wildlife reserves.

  4. The disturbance of timber extraction causes the species diversity to increase because of the new habitats created.

The temperature of the body is regulated almost entirely by nervous feedback mechanisms, and almost all these mechanisms operate through temperature regulating centers located in the hypothalamus. Following statements are as follows:
A. The anterior hypothalamic-preoptic area contains large numbers of heat-sensitive neurons, as well as about one third as many cold-sensitive neurons. These neurons are believed to function as temperature sensors for controlling body temperature.
B. The heat-sensitive neurons increase their firing rate 2- to 10-fold in response to a 10°C increase in body temperature. 
C. The cold-sensitive neurons, by contrast, increase their firing rate when the body temperature increases.
D. Anterior hypothalamus integrates the central and peripheral temperature sensory signals.
