Phylloicus hansoni larval population size structures in both predator-only and predator-third party stream settings

The dataset consists of larval caddisfly size distribution data across streams with different fish assemblages, with data on size, frequency and gut content data of predatory fish species. The related study investigates the relationship between the size structures of the larval caddisfly ( Phylloicus hansoni Denning) and different fish assemblages in Trinidadian streams in two settings: KO: Killifish-Only: upstream reaches where the predatory killifish, Anablepsoides hartii , is the only fish species KG: Killifish-Guppy: downstream reaches where killifish and the omnivorous guppy Poecilia reticulata coexist The data files are four .csv text files, accessible via MS Excel, open office and openly accessible text edit applications. ___ The following data files are from 5 streams, each with reaches with differing fish assemblages in 2013.

PHYL-size_frequency_data.csv - size frequency data consisting of body lengths and head capsule widths of caddisfly larvae: - stream: El Cedro = CED, Endler = END, Guard Dog Creek = GDC, Ramdeen = RDN, Trip Trace = TRT. - reach: stream setting - KG or KO - instar.group: HCW classification as Small = S (0.2 - 0.4 mm), Medium = M (0.5 - 0.8 mm), Large = L (0.9 - 1.1 mm) - HCW: head capsule width in mm - count: frequency PHYL-site_survey_data.csv - site survey data (stream & reach see above) - transect - transect id in the format TTTRRX (TTT = transect, RR = reach, X= sequential numerical id) - wetted.width in cm - depth in cm - canopy.cover in % - CBOM: coarse benthic organic matter gm -2 - CPUE: catch per unit effort PHYL-fish_size_class_data.csv - killifish size class data, with mean CPUE for each size class at each stream/reach: (stream & reach see above) - fish.SC - fish size classification: Juvenile = J (< 15 mm), Small = S (15-30 mm), Medium = M (30-45 mm), Large = L (45-60 mm), and Extra-Large = XL (> 60 mm) - mean.CPUE : mean CPUE (see above for definition) for specific stream and reach___ The following data was collected from killifish in 2011.
