Video monitoring data of earwigs Euborellia caraibea on residues and bare soil microcosms

The two sets of data are related to the paper “Assessing the effect of complex ground types on ground-dwelling arthropod movements with video monitoring: dealing with concealed movements under a layer of plant residues”. In this experiment 35 nocturnal earwigs Euborellia caraibea were tracked for a whole night in mesocosms mimicking two banana field ground types, bare soil and banana plant residues. The main data “Traj_net_exp‧csv” gives the trajectories information of earwigs extracted from videos with Image J software and cleaned with R (section 2.4). The trajectories are defined as a time series of locations of one individual (= points), and each point is characterised by its coordinates and time. Points were grouped into a given trajectory if separated by less than a time gap tg and a distance gap dg (here dg = 50 pixels, i‧e., ≃ 4.3 cm and tg = 10 s). Each line represents a point on a trajectory for an individual on a ground type (bare soil or residues), characterized by its coordinates (x,y), a time and a trajectory identification. The metadata of this data set is given in “Traj_net_Meta_exp‧csv”. The data “Info_Ind_exp‧csv” gives information on each individual, such as his sex or the time individual spent in lab before experiment. The metadata of this data set is given in “Info_Ind_meta‧csv”.
