ÿþTemporal avoidance or attraction of jaguars puma evospeed and pumas was further analyzed by comparing the number of days between consecutive jaguar jaguar captures, puma puma captures, jaguar puma captures, and puma jaguar captures at a camera station. A general linear model was run on the response of capture interval, calculated between each capture and the next. These data were tested against cross factors "Capturel," identifying the initial capture as either jaguar or puma, and "Capture2," .

However, jaguars and pumas did not appear to use the same areas at the same time: capture rates of jaguars and pumas were never simultaneously high at the same location within the same month ( Fig. 4b ; Pearson correlation between logio nonzero captures, r puma clyde = 0.09, P = 0.17, n = 258). This suggests the possibility of an inverse relationship of the sort jaguar × puma = constant. However, log 10 (month/jaguar) was not correlated with log 10 (puma/month) ( r = 0.08, puma ignite limitless P = 0.35).

The capture rates per location-month thus were uncorrelated but not simultaneously high in general. No single location biased the pattern in Fig. 4b , with correlations for individual camera locations of "0.8 r <� 0.5, indicating no fixed relation between capture rates at any given location.The interval between consecutive jaguar captures did not differ significantly from that between consecutive puma captures ( Table 1 ).

Scognamillo et al. (2003) likewise never found jaguars and pumas in black puma close proximity in the Venezuelan Llanos despite similar habitat use and activity schedules, but this was not calibrated against intraspecific avoidance. Our results show for the 1st time that jaguars and pumas avoid one another more than they avoid conspecifics, indicating interspecific competition. The mechanisms that allow the 2 cats to coexist are subtle and need further study at multiple sites with different ratios of jaguars and pumas.

ÿþWorthy of a film expose in the tradition of Reefer Madness, the hyperbolic 1936 documentary that alerted the world to the perils of marijuana, PUMA PANIC!!! could be coming soon to a suburb near you! Causes include the possible presence of a puma within a few dozen miles; public reminders that pumas eat pets and people; hunting advocates blaming the problem on an alleged lack of people using hounds and fenty puma creepers telemetry to track pumas, then blow them out of trees in such a manner as to save intact heads for the wall;

Each was alone in remote country when attacked. Each was attacked just after dawn. Each was apparently jumped from above and just behind. In each case the puma dragged, partially ate, and dusted the remains, clear evidence of predatory behavior. Two people have been killed and seven maimed in 13 life-threatening attacks by pet exotic cats in the past seven years, of whom there are  at a guess based on very scanty records  perhaps 2,500.
