This information revealed how reliable the results were, if there was enough data to be representative and aided in determining which data set (annual or pooled) was more representative. Standard Errors (SE) were calculated from 1,000 bootstrap replications. Data sets with intermediate (S ~0.5) to high

(S close to or above 1.0) social differentiation need far fewer associations than data sets with low differentiation to detect preferred companionship (Whitehead 2008a). This community is made up of three social clusters: Northern, Central, and Southern (Elliser and Herzing 2012). In order to correctly interpret the pattern of social associations, it was important to determine whether www.selleckchem.com/products/NVP-AUY922.html these social clusters were still

present before and after the hurricanes. Cluster definition was Dabrafenib in vitro confirmed using nonmetric multidimensional scaling (MD) and hierarchical agglomerative cluster analysis conducted with SOCPROG 2.3. In a MD plot, strongly associated individuals were plotted together and weakly associated were farther apart (Whitehead 2009). A plot with stress <0.1 is considered a good ordination (Whitehead 2008a). Hierarchical agglomerative cluster analysis produced a dendrogram where the individuals were arranged on one axis and their degree of association on another (Whitehead 2009). The Average-linkage method was used. The cophenetic correlation coefficient (CCC) determined how well the dendrogram matched the association matrix. A CCC of >0.8 indicates a good match, (Whitehead 2008a). These clusters overlapped in range and associations and have been confirmed to be part of one community (Elliser and Herzing

2012); therefore all individuals were analyzed together for CoA analysis. In 393 d at sea there were 173 d with encounters, with a total of 251 encounters (Table 1). A total of MCE公司 89 individuals were identified and sex was determined for 96% of the community. There were 43 females, 42 males, and 4 of unknown sex. Fifty-six individuals (63%) were sighted in every year of this study that was possible for that individual (i.e., they had been born and they were not considered lost—indicated by no sightings for more than 3 yr in a row). Before the hurricanes an average of 103 individuals were identified per year. After the hurricanes, this number dropped dramatically to 67.7 individuals (Fig. 2). Thirty-six regularly seen individuals (16 females and 20 males) disappeared and have not been resighted to date (through the 2012 field season). Losses were fairly consistent over age classes: 9 two-tones, 11 speckled, 6 mottled, and 10 fused individuals.
