We quantified reservoir host use as the number of hispid cotton rat or cotton mouse blood meals per resting shelter per day.
Blood meals from EVEV reservoirs (hispid cotton rat and cotton mouse combined) were a large percentage of total blood meals from all regions, constituting 48% of total blood meals from the lower, 84% from the middle, and 50% from the upper ENP region (Table 2).
cedecei abundance, reservoir (hispid cotton rat plus cotton mouse) host use, or proportion of blood meals from reservoir hosts ([chi square] = 4.08, df = 3; p = 0.252).
The finding that hispid cotton rat and cotton mouse together constituted a large portion (43.0%-86.2%) of Cx.
It is possible that wet-season transmission of EVEV is driven largely by the ecology and reproductive biology of cotton mouse and hispid cotton rat; however, a complex picture of rodent breeding and population dynamics emerges from past studies on this topic.
Density estimates of the endangered Key Largo woodrat and cotton mouse
(Neotoma floridana smalli and Peromyscus gossypinus allapaticola), using the nested-grid approach.
This also includes our conservative estimates of the probability of being successful while again accounting for differences in prey species in our base probability estimate (for example, it would be easier to prey upon a Key Largo cotton mouse
than an American crocodile in most situations).
Or is it more humane to let them live at the expense of natives, such as the Key Largo cotton mouse
? The danger is that instead of pondering difficult questions and coming up with our own solutions, we may opt to play a game of cat and mouse with the truth.
We identified an individual as a cotton mouse only when there was agreement using the criteria of both Hoffmeister (1977) and Laerm and Boone (1994).
Among 62 individual Peromyscus trapped on the Jackson County site, one confirmed cotton mouse was removed (SIUC #3722).
Because the species is on the periphery of its range and commonly inhabits bottomland forest, cotton mouse populations in southern Illinois likely are ephemeral, and undergo periodic extirpation as a result of flooding or other extrinsic factors.
Geographic and non-geographic morphological variation in the cotton mouse (Peromyscus gossypinus).
