Data from: The travel speeds of large animals are limited by their heat-dissipation capacities

Each heading below describes a column of the travel speed dataset. move_speed_ref: Unique reference number for each study reporting animal travel speed. The corresponding references are contained within the supplementary reference list file. move_mass_ref: Unique reference number for each study reporting animal body mass. The corresponding references are contained within the supplementary reference list file. scientific_name: Scientific name of the species according to the taxonomy of the Global Biodiversity Information Facility (accessed via GBIF.org during 2022). A small number of studies that report only the genus name or common name of the species are reported in our dataset as Genus sp. (e.g. Gazella sp.). One study, which estimated the travel speed and body mass of an unknown species of mouse via camera traps, is reported in our dataset as Amazon mouse sp. move_movement_mode: Categorical value indicating whether the reported travel speed corresponds to an animal engaged in flying, running, or swimming. This allows species to be accommodated that are capable of multi-modal locomotion (e.g. northern elephant seal, Mirounga angustirostris). taxon_group: Categorical value indicating the membership to one of eight animal groups (amphibian, arthropod, cnidarian, bird, fish, mammal, mollusc, reptile). thermo_reg: Categorical value indicating thermoregulatory strategy, i.e. the contribution of metabolic heat production to the maintenance of core body temperature ( during rest: Ectotherm (negligible contribution: matches ambient temperature), mesotherm (weak contribution: thermal lability in such as in tunas, lamnid sharks and leatherback sea turtles), endotherm (strong contribution: metabolic stable even when ambient temperatures are significantly below ). move_medium: Categorical value indicating whether the animal’s travel speed was measured during locomotion within the terrestrial realm (air) or aquatic realm (water). move_speed_method: Categorical value indicating whether travel speed was estimated directly (i.e. instantaneously via direct observation in real-time, animal-attached speedometer, or video recording) or indirectly from higher-resolution telemetry data (i.e. from changes in an animal’s spatial coordinates at intervals < 30 minutes apart). move_study_condition: Categorical value indicating whether travel speed was estimated under natural field conditions or under controlled laboratory setting such within an aquarium or mesocosm. Travel speeds of the smallest animals (e.g. arthropods) can only feasibly be estimated within a controlled setting. move_avgspeed_value: Categorical value indicating whether average travel speed was reported as a mean or median within the study. move_bodymass_kg: Continuous value indicating the average adult body mass (units: kilograms) of the species. In cases where the study’s reference numbers move_speed_ref and move_mass_ref differ, we referred to secondary literature sources to assign the average adult body mass of the species. In cases where only body length was given, we used published allometric equations to estimate the wet body mass move_avgspeed_ms: Continuous value indicating the average travel speed (units: metres per second) of the species reported within the study.下文各条目分别对应本行进速度数据集的一列字段。 move_speed_ref（行进速度研究唯一标识号）：每一项报道动物行进速度的研究对应的唯一参考编号，相关参考文献收录于补充参考列表文件中。 move_mass_ref（体质量研究唯一标识号）：每一项报道动物体质量的研究对应的唯一参考编号，相关参考文献收录于补充参考列表文件中。 scientific_name（物种学名）：依据2022年通过GBIF.org检索的全球生物多样性信息机构（Global Biodiversity Information Facility, GBIF）分类标准所确定的物种种学名。仅报道属名或俗名的少量研究，其物种信息在本数据集中以「属名 sp.」形式呈现（如瞪羚属未定种*Gazella sp.*）。另有一项研究通过红外相机估算了未知鼠类物种的行进速度与体质量，该物种在本数据集中记为亚马逊未定种鼠类*Amazon mouse sp.*。 move_movement_mode（运动模式分类变量）：分类变量，用于表明所报道的行进速度对应动物所处的运动状态，涵盖飞行、奔跑或游泳三类模式，以此兼容具备多模态运动能力的物种（例如北象海豹*Mirounga angustirostris*）。 taxon_group（类群分类变量）：分类变量，用于将物种归为以下八大动物类群之一：两栖类、节肢动物、刺胞动物、鸟类、鱼类、哺乳类、软体动物、爬行类。 thermo_reg（体温调节策略分类变量）：分类变量，用于表明体温调节策略，即代谢产热对维持核心体温的贡献程度（休息状态下：外温动物（代谢产热可忽略，体温与环境温度一致）、中温动物（代谢产热贡献较弱，体温存在热波动性，如金枪鱼、鼠鲨科鲨鱼及棱皮龟）、内温动物（代谢产热贡献显著，即使环境温度显著低于）。 move_medium（运动介质分类变量）：分类变量，用于表明动物行进速度的测量场景为陆地（空气环境）或水生环境（水环境）中的运动过程。 move_speed_method（行进速度测量方法分类变量）：分类变量，用于表明行进速度的估算方式：直接估算（即通过实时直接观测、佩戴于动物身上的速度计或视频录制进行瞬时测算），或基于高分辨率遥测数据间接估算（即通过间隔小于30分钟的动物空间坐标变化推导速度）。 move_study_condition（研究环境分类变量）：分类变量，用于表明行进速度的估算场景为自然野外环境，还是受控实验室环境（如水族馆或中型实验生态系统）。体型最小的动物（例如节肢动物）的行进速度仅可在受控环境中进行可行的估算。 move_avgspeed_value（平均速度统计量类型分类变量）：分类变量，用于表明研究中报道的平均行进速度为均值还是中位数。 move_bodymass_kg（体质量连续变量）：连续变量，用于表明该物种成年个体的平均体质量，单位为千克。当研究对应的move_speed_ref与move_mass_ref编号不一致时，本数据集将通过二手文献来源确定该物种的成年平均体质量。若研究仅提供了体长度数据，则通过已发表的异速生长方程估算其湿体质量。 move_avgspeed_ms（平均行进速度连续变量）：连续变量，用于表明研究中报道的该物种平均行进速度，单位为米每秒。
