Home Range, Diet, and Activity Patterns of Common Marmosets (Callithrix jacchus) in Very Small and Isolated Fragments of the Atlantic Forest of Northeastern Brazil

Table 4

Relationship between the number of gum feeding bouts by the common marmosets on the two exploited tree species and their structural variables in the studied forest fragments at Usina Trapiche, Northeast Brazil.

Tree species	Dependent variable	Independent variable	Spearman correlation coefficient
Tapirira guianensis	Number of feeding bouts X	Absolute density (ind./ha)	= 0, rho = 1, = 0.333
		Relative density (ind./ha)	= 0, rho = 1, = 0.333
		Relative dominance (%)	= 0, rho = 1, = 0.333
		Importance Value Index (IVI)	= 0, rho = 1, = 0.333
		Cover Value Index (CVI)	= 0, rho = 1, = 0.333
Parkia pendula	Number of feeding bouts X	Absolute density (ind./ha)	= 2, rho = 0.5, = 1
		Relative density (ind./ha)	= 2, rho = 0.5, = 1
		Relative dominance (%)	= 2, rho = 0.5, = 1
		Importance Value Index (IVI)	= 2, rho = 0.5, = 1
		Cover Value Index (CVI)	= 2, rho = 0.5, = 1
Tapirira guianensis and Parkia pendula	Number of feeding bouts X	Absolute density (ind./ha)	= 36, rho = −0.03, = 0.957
		Relative density (ind./ha)	= 36, rho = −0.03, = 0.957
		Relative dominance (%)	= 56, rho = −0.60, = 0.242
		Importance Value Index (IVI)	= 46, rho = −0.31, = 0.564
		Cover Value Index (CVI)	= 46, rho = −0.31, = 0.564
