說明

This dataset includes data of the freshwater crab genus Geothelphusa (Decapoda: Potamidae), their environmental parameters and stream indicators in eastern and southern Taiwan. This dataset is the result of 146 surveys (sampling events) of freshwater crab species and stream environment from 2013 to 2015 in 42 sampling sites throughout Taiwan, and a total of 12 species and 1,006 crabs of the Geothelphusa were recorded. The crab data include ‎existence or not, carapace width, carapace length, wet weight and sex. The stream environmental data include water temperature, pH value, dissolved oxygen, conductivity and three indicators (River Pollution Index, RPI; Water Quality Index 7, WQI7; citizen Qualitative Habitat Evaluation Index, cQHEI).

取樣方法

Crab investigation A complete search of 50 meters along the stream was conducted at each site. Then, six traps baited with dry pet food (Fig. 2) were set overnight (Chen et al. 2003) to collect the Geothelphusa crabs. After identifying species and measuring the traits of carapace breadth, carapace length, wet weight and sex, the captured crabs were released to their native habitats except for those with doubt in species identification needed for confirmation in the laboratory. Environmental parameters investigation The water temperature, pH value, dissolved oxygen and conductivity of the sampling sites were measured by a water quality meter (Horiba U-53) in situ. The water samples used to measure the values of BOD5, NH3-N, SS, FC and TP were preserved below 4 degree Celsius and analyzed in the laboratory within seven days from collection. In addition, the score table of cQHEI was also recorded in situ. The data of BOD5, NH3-N, SS, FC and TP were used to calculate two water quality indicators: River Pollution Index (Liou et al. 2004) and Water Quality Index 7 (Wen 2006). The data of the score table of cQHEI were used to calculate the other environmental indicator: the citizen Qualitative Habitat Evaluation Index (Hoosier Riverwatch 2019).

研究範圍 The freshwater crabs appear in almost all clean freshwater bodies, from moist lowland forests to rugged mountains (Cumberlidge et al. 2009). There are 57 recognized Geothelphusa species, with 39 species in Taiwan (Shy et al. 2021). Over twenty Taiwanese Geothelphusa species live in stream ecosystems below 500 m above sea level (Shy and Lee 2009). In this paper, the 42 sampling sites in Taiwan (Fig. 1) are all natural habitats of streams with an elevation distribution of 2-998 m, and 33 sites (78.6%) are below 500 m altitude. The data of the 22 monitoring sites were collected quarterly from the summer of 2013 to the summer of 2015, but some surveys were abandoned due to a lack of water-related data for the drought. The other 20 sites were surveyed only once in the summer and fall of 2014.

方法步驟描述:

  1. The water sampling and the seven parameters required to calculate two water quality indicators, River Pollution Index and Water Quality Index, including pH value, dissolved oxygen (DO), biochemical oxygen demand (BOD5), ammonia nitrogen (NH3-N), suspended solids (SS), fecal coliform (FC) and total phosphorus (TP), were operated following the protocols published by Taiwan Environmental Protection Administration in 2013.
