Data for: Seasonally mediated niche partitioning in a vertically compressed pelagic predator guild

Niche partitioning among closely related, sympatric species is a fundamental concept in ecology, and its mechanisms are of broad interest for understanding ecosystem functioning and predicting the impacts of human-driven environmental change. However, identifying mechanisms by which top marine predators partition available resources has been especially challenging given the difficulty of quantifying resource use of large pelagic animals. In the eastern tropical Pacific (ETP), three large, highly mobile and ecologically similar pelagic predators (blue marlin (Makaira nigricans), black marlin (Istiompax indica) and sailfish (Istiophorus platypterus)) coexist in a vertically compressed habitat. To evaluate each species’ ecological niche, we leveraged a decade of recreational fisheries data, multi-year satellite tracking with high-resolution dive data, and stable isotope analysis. Fishery interaction and telemetry-based three-dimensional seasonal utilization distributions suggested high spa..., , , # Data for: Seasonally mediated niche partitioning in a vertically compressed pelagic predator guild --- ## Description of the data and file structure Across all files, NA indicates no data were obtained for the given cell. In \"Logan et al_TimeSeries_DepthTemp.csv\" * Day - Date * Ptt - Satellite tag ID number, unique for each individual * Depth - depth in meters of the time series messages received * DateTime - Date and Time of time series messages received * Day1 - Date * Hour - Hour of Day * month - month of year * time - value that increases daily for inclusion of time since tagging in models * season - season of the year, based on month. Wet and Dry. * tag_seaon - indicates which tagging year each fish was tagged in * ascention - unique ID for each fish In \"Logan et al_IndividualDiveCharacterisitics.csv\", each row holds information about 1 individual dive * begdesc - date and time of when a dive descent began * enddesc - date and time of when a dive...近缘同域物种间的生态位分化（niche partitioning）是生态学中的核心概念，其形成机制对于理解生态系统功能、预测人类活动驱动的环境变化影响具有广泛的研究价值。然而，由于难以量化大型大洋性（pelagic）动物的资源利用方式，识别顶级海洋捕食者的资源分配机制尤为困难。 在东热带太平洋（ETP）区域，三种体型庞大、移动性极强且生态特征相似的大洋捕食者——蓝枪鱼（Makaira nigricans）、黑枪鱼（Istiompax indica）与旗鱼（Istiophorus platypterus）——在垂直压缩的生境中共存。为评估各物种的生态位，本研究利用了十年的休闲渔业数据、搭载高分辨率潜水数据的多年卫星追踪数据，以及稳定同位素分析技术。渔业交互与基于遥测的三维季节利用分布研究显示出较高的空间... # 数据集主题：垂直压缩大洋捕食者类群的季节介导生态位分化 --- ## 数据与文件结构说明 所有文件中，NA代表对应单元格未获取有效数据。 ### 「Logan et al_TimeSeries_DepthTemp.csv」 - Day：日期（Date） - Ptt：卫星标签编号，为每个个体的唯一标识符 - Depth：接收的时间序列报文对应的水深，单位：米 - DateTime：接收时间序列报文的日期与时间 - Day1：日期 - Hour：当日时刻（小时） - month：年度月份 - time：用于模型中纳入标记后时长的逐日递增变量 - season：基于月份划分的年度季节，分为湿季与干季 - tag_seaon：每条鱼的标记年份 - ascention：每条鱼的唯一标识符 ### 「Logan et al_IndividualDiveCharacterisitics.csv」 该文件每一行对应一次独立潜水的相关信息： - begdesc：潜水开始下潜的日期与时间 - enddesc：潜水...的日期与时间
