Mar 27, 2024 · Beach mice are monitored in a long-term track-tube survey at TAFB to determine population trends and identify occupancy patterns across the landscape. Presence or absence is determined using track-tubes secured to the ground using metal stakes and baited monthly with a small handful of sunflower seeds ( sensu Mabee, 1998 —Figure 2 ).
May 31, 2024 · We detected beach mice on 6,397 occasions across all tubes. Detections ranged from 0 to 147 observations/survey. Our top model suggested that beach mouse detection was related to cover type with positive associations with grassland and dune compared to scrub.
Mar 29, 2024 · Dynamic models revealed that local extinction probabilities of beach mice decreased with increasing elevation and dune habitat, followed by grassland, and scrub—highlighting high elevation dune...

Beach mice (Peromyscus polionotus) depend on coastal dune habitat in Alabama and Florida for burrow sites and other resources, making them vulnerable to natural and anthropogenic disturbances that are common to southeastern coastlines (Blair 1951; Oli et al. 2001; Pries et al. 2009; Swilling et al. 1998). Recent hurricanes have contributed to a dec...
Study system.—Beach mice are subspecies of the oldfield mouse (Peromyscus polionotus) that are unique to the coastal landscapes of Florida and Alabama (Van Zant and Wooten 2003). This study focuses on the Santa Rosa beach mouse (P. p. leucocephalus), which is the only subspecies of beach mouse not listed as threatened or endangered by the United St...
Monitoring abundance through time with track tubes.— Average track indexes exhibited strong covariation with average estimated abundance across seasons (Fig. 2a), as well as with average MKA across seasons. Covariation was strongest at lag distance 0 (Fig. 2b; Mh: r = 0.96, P < 0.01, MKA: r = 0.97, P < 0.01) but dropped precipitously at lag distanc...
This study provides information on associations between track indexes and estimated abundance on a temporal scale that captures seasonal variation in populations, which has not, been the focus of previous studies on track tubes (Glennon et al. 2002; Wiewel et al. 2007; but see Drennan et al. 1998). The strong covariation between average track index...

Appendix I
The relationship between track-tube index (cumulative number of tubes with tracks in a grid) and abundance estimated from trapping (Mhjackknife estimator), as a function of the number of days over which the track-tube index was calculated. For each sample period, the asterisk (*) indicates correlations discussed in the text (see “Materials and Methods” for further information).

Feb 9, 2017 · We released 48 captive-born mice in March 2010 and monitored the population through livetrapping across 8 sessions spanning 5 years. We evaluated temporal changes in microsatellite genetic diversity to determine whether mice born in the wild were derived from released mice.

Dec 18, 2020 · To aid the development of targeted management scenarios that are designed to achieve downlisting criteria, we developed a Bayesian network model that uses habitat characteristics to predict the probability of beach mouse presence at a 30-m resolution across a portion of the Florida Panhandle.
