THIS DESCRIBES THE NAMES OF THE VARIABLES THAT WERE USED IN OUR ANALYSES AND THAT CAN BE FOUND IN THE EXCEL OR CSV. FILES SUBMITTED ALONG THE MANUSCRIPT

TWO DIFFERENT CSV FILES HAVE BEEN SUBMITTED:

1. Encounters_YesNo.csv (this dataset allows to examine whether the snakes were encountered by an animal during videorecording and is used to characterized the factors explaining the occurence of an encounter between our snakes and other animals);

#SPEC = SPECIES OF SNAKE (BJA = Bothrops jararaca; BJU = Bothrops jararacussu)
#ID = SNAKE IDENTIFICATION NUMBER (ONE PER INDIVIDUAL)
#IDRELOC = THE RELOCATION NUMBER FOR A GIVEN SNAKE (NOT USED IN ANALYSES)
#VIDEOSEQ = A VARIABLE USED TO BREAK UP A GIVEN VIDEO AT A SPECIFIC RELOCATION FOR A SNAKE INTO DIFFERENT TIMEOFDAY SEGMENTS (NOT USED IN ANALYSES)
#TIMESTART = INDICATES THE TIME OF THE START OF THE VIDEO (NOT USED IN ANALYSES)
#TIMEEND = INDICATES THE TIME OF THE END OF THE VIDEO (NOT USED IN ANALYSES)
#DATESTART = INDICATES THE DAY OF THE START OF THE VIDEO (NOT USED IN ANALYSES)
#DATEEND = INDICATES THE DAY OF THE END OF THE VIDEO (NOT USED IN ANALYSES)
#ENCOUNTER = INDICATES WHETHER AN ANIMAL ENCOUNTERED THE SNAKE BEING VIDEOTAPED (No = 0; Yes = 1)
#ANIMENCOU = INDICATES THE TYPE OF ANIMAL THAT ENCOUNTERED OUR SNAKE (Aves, Mammalia, NA [NON OBSERVED; NOT USED IN THIS ANALYSIS)
#NOFANIMENCOU = INDICATES THE NUMBER OF ANIMALS THAT ENCOUNTERED OUR SNAKE DURING THIS VIDEO (NOT USED IN ANALYSES)
#SEASON = THE CATEGORICAL VARIABLE CONTRASTING THE DRY SEASON FROM THE WET SEASON
#TIMEOFDAY = THE CATEGORICAL VARIABLE INDICATING WHETHER THE ENCOUNTER OCCURRED DURING NIGHTIME (A-NIGHT) OR DAYTIME (B-DAY)
#CAMDIST = INDICATES WHETHER THE CAMERA DISTANCE TO THE SNAKE VARIABLE WAS RECORDED (Yes; No)
#CAMERADIST = INDICATES THE DISTANCE OF THE CAMERA FROM THE SNAKE (WHEN IT WAS RECORDED)
#CAMERADIST_SCALED = THE CONTINUOUS PREDICTOR INDICATING THE CAMERA DISTANCE TO THE SNAKE. THIS VARIABLE HAS BEEN Z-TRANSFORMED
#CAMDIST_SCALEDBJU = THE CONTINUOUS PREDICTOR INDICATING THE CAMERA DISTANCE TO THE SNAKE. THIS VARIABLE HAS BEEN Z-TRANSFORMED, AND INCLUDES ONLY DATA FROM Bothrops jararacussu
#TIMEFOV = INDICATES THE LENGTH OF THE VIDEO IN MINUTES
#TIMEFOVLOG = LOG-TRANSFORMED VIDEO LENGTH
#TIMEFOVLOG_SCALED = THE CONTINUOUS PREDICTOR INDICATING THE LENGTH OF THE VIDEO. THIS VARIABLE HAS BEEN LOG-TRANSFORMED AND Z-TRANSFORMED
#TIMEFOVLOG_SCALEDBJU = THE CONTINUOUS PREDICTOR INDICATING THE LENGTH OF THE VIDEO. THIS VARIABLE HAS BEEN LOG-TRANSFORMED AND Z-TRANSFORMED, AND INCLUDES ONLY DATA FROM Bothrops jararacussu

1. Encounters_Only_AM.csv (this dataset allows to model how various factors influenced whether the encountered animal was a bird or a mammal as well as detectability)

#SPEC = SPECIES OF SNAKE (BJA =Bothrops jararaca; BJU = Bothrops jararacussu)
#ID = SNAKE IDENTIFICATION NUMBER (ONE PER INDIVIDUAL)
#RELOCNUM = THE RELOCATION NUMBER FOR A GIVEN SNAKE (NOT USED IN ANALYSES)
#EVENTNUM = A NUMBER SPECIFYING AN EVENT OCCURING AT A RELOCATION NUMBER FOR A GIVEN SNAKE (NOT USED IN ANALYSES)
#DAY = THE DATE THE ENCOUNTER WAS RECORDED
#TIME= THE TIME AT WHICH THE ENCOUNTER WAS RECORDED
#SEASON = THE CATEGORICAL VARIABLE CONTRASTING THE DRY SEASON (=0) FROM THE WET SEASON (=1)
#TIMEOFDAY = THE CATEGORICAL VARIABLE INDICATING WHETHER THE ENCOUNTER OCCURRED DURING NIGHTIME (=0) OR DAYTIME (=1)
#DEA = INDICATES THE RECORDS FOR WHICH WE COULD SCORE DETECTABILITY OF SNAKES BY THE ENCOUNTERED ANIMAL
#PEA = INDICATES THE RECORDS THAT WE CONSIDERED AS A VALID PREY ENCOUNTER THAT COULD RESULT IN AN OFFENSIVE STRIKE FROM THE SNAKE (IE, A PREY ANIMAL WHICH CAME WITHIN 40CM OF THE SNAKE)
#DISTSNAKE = THE CLOSEST DISTANCE BETWEEN THE SNAKE'S SNOUT AND THE ENCOUNTERED ANIMAL
#DISTSNAKE_CWC = THE CONTINUOUS PREDICTOR INDICATING THE CLOSEST DISTANCE THAT THE ENCOUNTERED ANIMAL GOT TO THE SNAKE. THIS VARIABLE HAS BEEN Z-TRANSFORMED ('OBSERVED VALUE - MEAN OF THE VARIABLE'/STANDARD DEVIATION OF THE VARIABLE))
#DISTSNAKE_CWC_BJU = THE CONTINUOUS PREDICTOR INDICATING THE CLOSEST DISTANCE THAT THE ENCOUNTERED ANIMAL GOT TO THE SNAKE. THIS VARIABLE HAS BEEN Z-TRANSFORMED USING ONLY Bothrops jararacussu DATA
#ENCOUNTER = INDICATES WHETHER AN ANIMAL ENCOUNTERED THE SNAKE BEING VIDEOTAPED
#ANIMAL_CLASS = THE CATEGORICAL PREDICTOR INDICATING THE TYPE OF ANIMAL THAT ENCOUNTERED THE VIDEOED SNAKE (MAMMAL = 0; BIRD = 1)
#ANIMAL_ORDER = THE TAXONOMIC ORDER THE ANIMAL BELONG TO (NOT USED IN ANALYSES)
#TAXON_ID = THE IDENTIFICATION OF THE OBSERVED ANIMAL TO THE LOWEST TAXONOMIC LEVEL (NOT USED IN ANALYSES)
#ANIMTYPE = INDICATES WHETHER THE ENCOUNTERED ANIMAL IS A PREY, A PREDATOR, A NEIGHBOR, OR AMBIGUOUS
#STRIKE = INDICATES WHETHER THE SNAKE STRUCK AT THE ANIMAL (Yes or No: NOT USED IN ANALYSES, BUT REPORTED DESCRIPTIVELY IN THE TEXT OF THE MANUSCRIPT)
#STRIKENUM = INDICATES THE NUMBER OF STRIKES BY THE SNAKE WITHIN A GIVEN INTERACTION WITH A SINGLE ANIMAL (NOT USED IN ANALYSES BUT REPORTED HERE)
#STRIKESUCCESS = INDICATES WHETHER THE SNAKE SUCCESSFULLY STRUCK AT THE ANIMAL (0 = No, 1 = Yes; NOT USED IN ANALYSES, BUT REPORTED DESCRIPTIVELY IN THE TEXT OF THE MANUSCRIPT)
#SNAMOVT = THE CATEGORICAL PREDICTOR INDICATING WHETHER THE SNAKE MOVED IN RESPONSE TO THE APPROACHING ANIMAL (NO = 0; YES = 1)
#DETECTED = THE CATEGORICAL RESPONSE VARIABLE INDICATING WHETHER THE ANIMAL THAT ENCOUNTERED THE VIDEOED SNAKE DETECTED IT (NO = 0; YES = 1)
