Eptesicus fuscus
(Big Brown Bat)Overview:
Conservation Status
Population Analysis
- For the 28,847 species in the Class Mammalia (Mammals), we average 14.56 observations each in our database; for the Big Brown Bat, we have 1,984 observations. Compared to other species in this Class, this species is extremely common.
- A two-sample t-test can be used to determine whether the trend in observations of the Big Brown Bat is the same as the trend in observations of Mammalia. Is this species just as common, as a proportion of all observations, as it once was? The answer is no, changes in observation rate of this species significantly differ from changes in observation rate of its Class. (t=31.601, p<0.001)
- How do observation rates of the Big Brown Bat differ from those of Mammalia? To answer this, we examined the percentage of observerations for Mammalia that were observations of the Big Brown Bat each year. We then correlated this percentage with observation year. If observations of the Big Brown Bat are becoming more common relative to other species of Mammalia, the correlation should be positive, but if it is becoming less common, the correlation should be negative. In fact, the correlation is negative (r=-.65), with a negative slope (m = -.024), suggesting that the Big Brown Bat may be in decline relative to other species of Mammalia. This correlation is statistically significant. (F = 59.02, p<.05)
- The scatter chart to the right shows the percentage of all observations for Mammalia each year that were observations of the Big Brown Bat.
