“…However, evidence from other kinosternids indicates that egg size is not constrained by the pelvis (van Loben-Sels et al, 1997;Wilkinson et al, 2005;Macip-Ríos et al, 2009). To our knowledge no study has tested optimal egg size theory or the morphological constraint hypothesis in kinosternid turtles using King's (2000) allometric approach.…”

“…It can be found in small and shallow aquatic habitats such as ponds or streams and in large river systems (Iverson, 1999), with populations reaching densities of 1,020 individuals/ha (Macip-Ríos et al, 2009). A preliminary study of reproductive characteristics across several populations of K. integrum showed little geographic variation in life history traits, with positive correlations of clutch size and egg mass to maternal body size (Iverson, 1999).…”

“…Later, Macip-Ríos et al (2009) documented a positive correlation between clutch size to body size and no pelvic constraint in one population of K. integrum in southern Mexico. The Mexican mud turtle nests from May to October, with a mean clutch size of 4 (1-8 eggs), and is believed to produce 1-4 clutches per breeding season (Iverson, 1999;Macip-Ríos et al, 2009).…”

“…The statistical analyses were done with combined data of populations in order to reach a suitable sample size, making this, to our knowledge, the largest data set analyzed for K. integrum to date (Iverson, 1999;Macip-Ríos et al, 2009). Subsequently the entire data set was divided into two body size categories: small females (< 140 mm PL) versus large females (> 140 mm PL).…”

“…We measured the maximum plastron length (PL) of each female using a plastic ruler (1 mm). Females chosen for the study were > 100 mm in PL, an estimate of the minimum size at first reproduction (Iverson, 1999;Macip-Ríos et al, 2009). We also measured non-gravid body mass of each female captured with a triplebeam balance (0.10 g).…”

Optimal offspring size theory states that natural selection should balance reproductive output by optimizing between offspring size and offspring number. If a species has evolved an optimal offspring size, the fitness of larger females should be increased by simply producing more offspring of an optimum size. In contrast, when offspring size is not optimized, the morphological constraint hypothesis may apply, and in this case, maternal fitness is increased by producing the greatest number of the largest offspring that mothers are physically capable of producing. We used a log-log allometric regression approach on clutch size, egg size, and body size data to test the application of optimal offspring size theory and the morphological constraint hypothesis in the Mexican mud turtle (Kinosternon integrum) in southern Mexico. Our results indicate that this turtle seems to follow the morphological constraint hypothesis when all data are analyzed together, but when data are divided between small (< 140 mm plastron length) and large females (> 140 mm plastron length), optimal offspring (egg) size theory was supported only in large females, while the morphological constraint hypothesis was supported in small females. Our results thus indicate that K. integrum females may increase their fitness in two different, size-dependent ways as they grow from size at sexual maturity to maximum body size.

We describe the home range and movements of a population of Kinosternon integrum in Tonatico, Estado de México, México, over 3.5 years (during rainy and dry season months) using radiotelemetry in 37 adult turtles. The results showed that the home range of K. integrum was 0.151 ± 0.051 ha using 50% kernel density estimator (KDE), and 0.657 ± 0.214 ha using 95% KDE; the home range did not vary between sexes. Kinosternon integrum showed low distances traveled 51.44 ± 4.50 m, where 87.3% (n = 373) of movements were <100 m. The distance traveled differed by season, and movement category (aquatic and terrestrial movements). The shortest distance occurred during the dry season, during which some individuals move to estivation sites, and these movements were shorter than movements to artificial ponds (cattle ponds). In this population, home range and movement are similar to other species of the genus Kinosternon. Overall, the results indicate than K. integrum are highly dependent on aquatic habitats, but also utilize the terrestrial habitats for different biological activities, and to maintain viable populations. Therefore, the conservation of the entire inhabited area is fundamental. This study highlights the need to increase the studies, in Central México, concerning habitat use of freshwater turtles in order to increase the efficiency of conservation strategies.
