title: Capture history data for: Sub-seasonal correlation between growth and survival in three sympatric aquatic ectotherms

description: Animals experience seasonally changing conditions in temperate regions,
 thus population vital rates change seasonally. However, knowledge is
 lacking on patterns of seasonal correlation between growth and survival in
 sympatric ectotherms, and this knowledge gap limits our understanding of
 environmental change impacts on animal populations and communities. Here,
 we investigated sub-seasonal (2-month intervals) correlation between
 growth and survival in three stream fishes (bluehead chub Nocomis
 leptocephalus, creek chub Semotilus atromaculatus, and mottled sculpin
 Cottus bairdii) in South Carolina, USA, via a mark-recapture survey over
 28 months.  We found that the patterns of temporal correlation
 between growth and survival differed among the sympatric species. Growth
 increased and survival decreased with water temperature in two eurythermal
 species (bluehead chub and creek chub), resulting in a negative
 correlation between growth and survival. Growth peaked in sub-seasons with
 an intermediate water temperature range in a third stenothermal species
 (mottled sculpin), while survival decreased with water temperature for
 this species too. Consequently, there was no significant negative or
 positive correlation between sub-seasonal growth and survival in the
 stenothermal species.  Negative correlation among population
 vital rates stabilizes population size over time and buffers animal
 populations from environmental change because the vital rates are not
 affected simultaneously in the same direction, indicating some degree of
 resiliency in the face of climate changes in the two eurythermal species.
 However, such a demographic mechanism of resiliency could be maintained so
 long as climate warming does not exceed optimal growth temperature, above
 which a negative correlation between growth and survival may no longer be
 maintained.
description: We conducted mark-recapture
 sampling in the 740m study area of Indian Creek, South Carolina, USA,
 between November 2015 and March 2018 at an interval of two months (mean =
 61 days [range = 48-70]). An average window of 4 days was required for
 each sampling occasion (range = 1-10 days). The study area was divided
 into 20-m sections, which were sampled in an upstream direction on each
 sampling occasion by backpack electrofishing units (Smith Root Model
 LR-24; and Halltech Aquatic Research Inc. Model HT-2000) using a two-pass
 depletion approach.  We marked all
 captured fish ≥ 60 mm in total length (TL) for bluehead chub and creek
 chub and ≥ 50 mm TL for mottled sculpin with 8-mm passive integrated
 transponder (PIT) tags (Oregon RFID; Biomark). We measured TL (mm) of all
 marked and recaptured fish before they were returned to the section of
 capture alive. Across 15 sampling occasions between November 2015 and
 March 2018, we uniquely tagged a total of 429 individuals of bluehead
 chub, 664 individuals of creek chub, and 928 individuals of mottled
 sculpin.  Our data set
 includes a capture histority of 2,201 individuals of the three fish
 species used in Cormack-Jolly-Seber
 models.
