Mammalogy - Study guides, Class notes & Summaries

An in depth, 40 slide Power Point covering class notes for all lectures up to Exam 1 for BIOL 427 at McNeese State University. The notes cover the basics of characteristics of mammals, evolution of mammals and early ancestry, mammalian dentition/skeletal characteristics/foot posture, mammalian modes of locomotion/modes of feeding, and environmental adaptations of mammals.

As velocity of an animal increases, so does the cost of locomotion How are velocity and cost of locomotion related? Body mass Cost of locomotion varies with what? Basal metabolic rate What do we call the baseline energy expenditure? Positively correlated How are basal metabolic rate and body mass related? Slope In a logarithmic scale, what is the exponent related to? Equal increase in both variables On a graph demonstrating basal metabolic rate vs, body mass, what does a slope of 1 m...

Nutrient flow is the natural process which provides for the cycling of chemicals between biotic and abiotic factors including water, oxygen, carbon, nitrogen and phosphorus. - Answer-True A volcano has erupted and has now cooled off to leave bare rock. Over time, lichens have colonized on the rock, breaking it down and creating soil. Soil allowed grasses and flowering plants to grow. In this example, which of these was most likely the pioneer species? - Answer-Lichens Samantha is developin...
