title: Phytoplankton species abundance in Tokyo Bay (Japan) from 1998 to 2019

description: Tokyo Bay is a semi-enclosed coastal system located in the center of Japan. Eutrophication has progressed since 1950, resulting in red tides and blue tides appearing frequently. This data paper reports the abundance of phytoplankton species sampled monthly from April 1998 to March 2019 at 17 stations in Tokyo Bay. Monitoring has been carried out by Chiba Prefectural Government. Phytoplankters were enumerated by microscopy as numbers of cells or colonies. The abundance of each species was expressed as cells per milliliter of sea water. The total cell density ranged from 102 to 106 cells·ml−1. The dominant taxa were diatoms, such as Chaetoceros spp., Skeletonema spp., and Thalassiosira spp. in most of the months. The dominant diatom species reached concentrations of 106 cells·ml−1. Microflagellates or Cryptomonadaceae were also abundant, especially in winter, reaching 106 cells·ml−1. These data can be used to appreciate how anthropogenic disturbances such as eutrophication and global warming affect the density and community composition of phytoplankton.

title: Long-term flowering records of herbaceous plants in Tokyo, Japan during 1994-2015 through citizen science

description: We provide a 22-year period (1994–2015) dataset of flowering records of herbaceous plant species in Tokyo, Japan. Trained volunteers of the citizen group conducted field surveys using a citizen science approach. During monthly surveys, the volunteers recorded the flowering phenology of plants in an area of the Institute for Sustainable Agro-ecosystem Services and Tanashi Forest (The University of Tokyo) in Nishitokyo City, Tokyo, Japan. In all, 5982 observations on 401 species including 11 subspecies, 44 varieties, 6 forma from 70 families of herbaceous plants were collected in Tokyo. These data provide an overview of the flowering phenology of herbaceous plants in urban areas, where regular monitoring is often difficult due to the environment being highly urbanized and subject to intensive weed control. The complete data set for this abstract published in the Data Paper section of the journal is available in electronic format in MetaCat in JaLTER at http://db.cger.nies.go.jp/JaLTER/metacat/metacat/ERDP-2021-05.1/jalter-en.

title: Evaluating the soil microbe community-level physiological profile using EcoPlate and soil properties at 33 forest sites across Japan

description: We present the largest freely available EcoPlate dataset for Japan, comprising data collected from a network of 33 natural forest sites (77 plots) in regions of East Asia ranging from cooltemperate to subtropical. EcoPlate is a 96-well microplate that contains three repeated sets of 31 response wells with different sole carbon substrates. The utilization of each carbon substrate by the microbial community is quantified by the color density of the well during incubation. EcoPlate can provide a multifunctional index of a soil microbial community. Soil properties (water content, carbon [C] and nitrogen [N] contents, the C/N ratio, and pH) that are essential for interpreting the EcoPlate results were also measured. The network is part of the Forest and Grassland Survey of the Monitoring Sites 1000 Project established by the Ministry of the Environment. Using a standardized protocol, soil was sampled between September and December 2020. A preliminary principal component analysis was performed on the temporal integration of color density using 31 substrates. For the temporal integration, we calculated the cumulative amount of color development by integrating the color density development curve. PC1 contributed 55.6% and is thought to represent the magnitude of the overall absorbance of all substrates. The model of environmental factors including elevation and the model of soil properties, including water content and pH, were selected as the best fit models for variation in PC1. EcoPlate data enable the meta-analysis of comparative studies among forest types and testing community ecology and ecosystem function hypotheses at broad spatial scales.

title: Bee occurrence data collected in citizen science program “Hanamaru-Maruhana national census” in Japan

description: To understand bee distributions in Japan, we started citizen science program “Hanamaru-Maruhana national census (Bumble bee national census in English)” from 2013, and collected bee photographs taken by citizens. Bee photographs were collected via e-mail or “Mobile Phone System and Cloud Services” provided by Fujitsu FIP, Co. Species were identified from photographic images, and latitude-longitude data was extracted from GPS data in Exif information of photographs or address in text of e-mail. We have confirmed all 16 bumble bee species inhabiting in the Japanese archipelago excluding the Kurile Islands, and have got 5,503 records of these bumble bees. In addition, we have got 380 records of three carpenter bee species that are often mistaken for bumble bees by citizens. This occurrence data covers the time range from September 2006 to October 2018, the latitudinal range from 26.45 to 45.29, and the longitudinal range from 127.80 to 145.82. The latitude-longitude data was rounded off to two decimal places in the published dataset for protecting privacy rights of citizens. In addition, the latitude-longitude data of five rare bumble bee species/subspecies was rounded off to one decimal place for protecting their habitats. The complete data set for this abstract published in the Data Paper section of the journal is available in electronic format in MetaCat in JaLTER at http://db.cger.nies.go.jp/JaLTER/metacat/metacat/ERDP-2021-04.1/jalter-en.

title: Forest stand structure, composition, and dynamics in 34 sites over Japan

description: This data paper reports tree census data collected in a network of 34 forest sites in Japan. This is the largest forest data set freely available in Japan to date. The network is a part of the Monitoring Sites 1000 Project launched by the Ministry of the Environment, Japan. It covers subarctic to subtropical climate zones and the four major forest types in Japan. Forty two permanent plots usually 1 ha in size were established in old-growth or secondary natural forests. Censuses of woody species &gt; 15 cm girth at breast height were conducted every year or once during 2004 to 2009. The data provide species abundance, survivorship and stem girth growth of 52534 individuals of 334 tree and liana species. The censuses adopted common census protocol, which provide good opportunities for meta-analyses and comparative studies among forests. The data have been used for ecological studies as well as for the biodiversity reports published by the Ministry of the Environment.

title: Phytoplankton species abundance in Lake Kasumigaura (Japan) monitored monthly or biweekly since 1978

description: This data paper reports the abundance of phytoplankton species in monthly or biweekly samples collected from May 1978 through March 2010 at two stations on Lake Kasumigaura, a shallow lake that is the second-largest lake in Japan. The data set of quantitatively over several decades is unique among the available published data papers concerning lakes or plankton and continues to be freely available. The monitoring has been performed as a component of the Lake Kasumigaura Long-term Environmental Monitoring program, conducted by the National Institute for Environmental Studies (NIES) since 1977. The data set details 173 phytoplankton species (or taxa), that can be identified by using an optical microscope and records their abundance. The abundance of each species is expressed in units of volume (μm3) per milliliter of lake water. This approach allows quantitative comparisons among taxa because the cell size of phytoplankton varies by several orders of magnitude among taxa. The phytoplankton data include 39 species (taxa) of Cyanophyta, 67 Chlorophyceae (Chlorophyta), 3 Prasinophyceae (Chlorophyta), 1 Raphidophyceae (Heterokontophyta), 6 Euglenophyceae (Euglenozoa), 4 Dinophyceae (Dinophyta), 38 Bacillariophyceae (Heterokontophyta), 6 Chrysophyceae (Heterokontophyta), 7 Xanthophyceae (Heterokontophyta), 1 Cryptophyceae (Cryptophyta) and 1 Prymnesiophyceae (Haptophyta). The data have been used for ecological and environmental studies and for studies on lake management.
