title: Large-scale ecological field data for satellite validation in deciduous forests and grasslands

description: In-situ accurate data sets of a leaf area index (LAI), above-ground biomass (AGB), and a fraction of photosynthetically active radiation (fAPAR) are indispensable to validate and to improve ecological products obtained from satellites. In-situ data for satellite validation must be created not from a single point data but an areal data (such as multiple points data) representing a satellite footprint. Using multiple points’ data, the error in in-situ data can be calculated statistically. The quantification of the error in the in-situ data enables us to separately evaluate the discrepancy between the satellites’ products and the in-situ data as the error in the in-situ data and the estimation error in the products. Besides, the accuracy of in-situ data is required to be much higher than the accuracy of the satellite products which was officially set. To obtain such in-situ data, we have established observation sites for typical land cover types in East Asia, from temperate to cool ecosystems: deciduous needle-leaved forest (DNF), evergreen needle-leaved forest (ENF), deciduous broad-leaved forest (DBF), and grassland (GL). We conducted the observations in the 500 m × 500 m area, which is the footprint scale of the Global Change Observation Mission-Climate (GCOM-C) satellite. In this paper, the data of LAI, AGB, and fAPAR observed at DNF, DBF, and GL (i.e., except at ENF) are reported. These data are useful even for the validation of other satellite products, especially with higher spatial resolution. Also, the long-term tree census data from 2005 to 2018 at DNF are reported.

title: Specimen based records and geographic locations of carabid beetles (Coleoptera) collected mainly by Dr. Kazuo Tanaka

description: Ground beetles of suborder Adephaga are often considered bioindicators of natural

environments because their habitats and abundances strongly depend upon environmental factors. Although their importance and usefulness are already known, there are limited data regarding voucher specimens in Japan. Biodiversity data based on voucher specimens are of high quality and reliability. In this data paper, we compile the records of Caraboidea collected mainly by Dr. Kazuo Tanaka. We also detail the time and locality of collection based on the labels of specimens deposited in the Institute for Agro- Environmental Sciences, National Agriculture and Food Research Organization, Japan.

This collection facility contains 15,675 records of 673 species collected from 1947 to 1997. All data are deposited in the Global Biodiversity Information Facility (GBIF) through the Japan Node of GBIF and are thus accessible through the GBIF portal under the Creative Commons Attribution 4.0 International license.

title: Distribution records of apple snails (Pomacea spp.) in Japan collected during 2017–2019 through a citizen science project for introduced species conducted by the Osaka Museum of Natural History

description: Apple snails Pomacea canaliculata and P. maculata are herbivorous freshwater gastropods native to South America and are introduced species widespread in western and southern Japan. Although they affect rice culture and are invasive to native ecosystems, high-resolution distribution data are not available for these species. I mapped the distribution of Pomacea species using the citizen science approach, by asking volunteers to report the geographical location along with the presence or absence of apple snail egg capsules or snail shells during 2017–2019. In total, 1304 present and 508 absent records were collected, which revealed the distribution outlines of apple snails, especially in the Kansai area. Here, I provide a dataset of observation dates, location coordinates, volunteer names, and supplemental information.

title: Monitoring of seagrass along southern Andaman coast of Thailand

description: Seagrass ecosystems provide various important ecosystem services in the marine environment. However, their global distribution has been declining since the 1800s. At the current rate of decline of almost 1.5% per year, almost half the meadows will be lost in the next 100 years. To prevent or minimize their loss, global monitoring programs have been established, such as SeagrassNet. The aim of the program is to introduce a global monitoring protocol and to preserve seagrass ecosystems by increasing scientific knowledge of them. The aim of this study was to gather data obtained by this protocol and to set a baseline for knowledge of the seagrass meadows in marine national parks in Southern Thailand. The data were collected from February 2006 until March 2009, three times a month at three national parks: Haad Chao Mai, Tarutao and Mu Ko Petra. At each site the data were obtained along three transects parallel to the coast with 12 quadrats, in which species coverage and biomass above and below ground were recorded. These data sets can be used in future seagrass health assessments, in observation of the temporal changes of the meadows and as a baseline for restoration efforts.

title: Dataset of forewing length of Japanese and Taiwanese butterfly species

description: Revealing how species assemblages are structured is one of the themes in community ecology and macroecology. The information of species traits as well as geographic occurrence would help analyze the pattern and process of species interactions and community assembly. Butterfly species are one of the best‐studied groups about their distribution and tons of their occurrence data exist. Also, life history traits, especially interaction with host plants are well‐described. However, the body size information is still poor although this is one of the most important characters affecting their distribution and life history traits. Here, we constructed a data set of the forewing length of butterflies by extracting the information from five Japanese and Taiwanese picture books. We measured 6,211 forewing lengths for a total of 524 species. Scientific, family and common names of the butterflies distributed in Japan were based on a Japanese picture book, and the other species distributed in Taiwan were based on Taiwanese picture books. Also, we added the information of butterfly names based on Binran database. Each record of butterflies is linked with the corresponding taxonomic names in the other two books to easily identify the species even when the names used in the three books and the Binran database are not the same. The dataset will be useful for basic and applied biological studies of butterflies because their forewing length is a proxy of their body size and dispersal ability, which could be important determinants of their physiology, distribution, ecosystem functioning and evolution.

title: Biodiversity dataset of vascular plants and birds in Chinese urban greenspace.

description: Urban greenspace plays an important role in buffering the threat of urbanization to biodiversity. Biodiversity research in urban greenspace is essential for understanding the impacts of human activities on biodiversity and the associated ecosystem functioning and services in urban ecosystems. However, we lack large-scale biodiversity datasets in urban greenspace for macroecological studies. In this paper, we provided a comprehensive biodiversity dataset of vascular plant and bird species in 286 university campuses and 118 urban parks in 143 cities in China, covering a wide range with different levels of urbanization (20–50°N in latitude and 81– 130°E in longitude). Plant species were classified into different growth forms, and bird species were identified as resident or migrant. In total, the dataset contains 46,558 occurrence records for 5,915 plant species (about 18% of all Chinese vascular plant species) and 6,423 records for 546 bird species (around 40% of all recorded bird species in China). This dataset provides an important data source for evaluating the anthropogenic effects of biodiversity changes and advancing urban ecology.

title: Observation of leaf phenology of trees in a secondary deciduous broad-leaved forest in northern Chugoku Mountain Range, western Japan, from 2004 to 2016

description: Long-term record of leaf phenology of woody plants that have high longevity and that have been growing on the same site for a longer time could be one of the good indicators for assessing the effects of climate change on forest ecosystem functioning. Since climatic conditions could be different among locations, we need to record the phenology of forest plants growing under various climate types. Here, we report seasonal changes in leaf abundance of deciduous trees during a 13-year period in the Sambe Forest of Shimane University located in northern Chugoku Mountain Range, western Japan [35° 9′ N, 132° 37′-40′ E, 300–628 m above sea level (asl)]. Northern Chugoku Mountain Range is situated in the west end of Japan Sea side climate. Our study would provide the first record of tree phenology in this region. We examined 8 species belonging to 8 genera common in a secondary deciduous broad-leaved forest in western Japan. Habitats of native trees ranged from canopy to understory in the forest and pioneers in an open site. Some of trees were exceptionally planted in an arboretum in the Sambe Forest. Leaf types included single leaf (i.e., Carpinus tschonoskii, Swida macrophylla, etc.) and pinnate leaves (i.e., Aesculus turbinata and Phellodendron amurense). We observed changes in the relative leaf abundance caused by budburst, leaf expansion, and leaf shedding of the fixed shoots of targeted trees during three-day to three-week intervals from March to December each year from 2004 to 2016. Over the 13-year period, we used a digital camera to take photographs of the shoots that were processed to estimate the leaf abundance. Our data was obtained from common tree species that have a wide habitat range and are distributed nationwide. Therefore, comparison of our data with those data in other climate types may significantly contribute to understand the effect of climate change across Japan on forest plants.

title: Acoustic monitoring data of anuran species inside and outside the evacuation zone of the Fukushima Daiichi power plant accident

description: The Fukushima Daiichi power plant accident led to large-scale and long-term evacuation zones in which usual land-use activities such as farming have been stopped. In particular, the loss of irrigated rice paddies is hypothesized to have seriously impacted freshwater biodiversity. In 2014, we started acoustic monitoring of frogs by using digital voice recorders in and around the evacuation zone. For the monitoring project, 52 and 57 monitoring sites were located within schoolyards (including those that had been converted into community centers) to examine the frog assemblages in the urban and rural landscapes of the region in 2014 and 2015, respectively. At each site, a digital voice recorder was installed during the period from May to July, and we recorded 10 min a day at night using a timed-recording mode. We divided the audio data into 20-sec segments and identified species recorded in segments sampled from late May to late June (partly in early July). We identified eight frog species from 1,962 audio segments in total (correspond to four days per year in principal). For each species, intensity of calling at four levels was also recorded as an index of abundance. We are continuing to monitor and intend to update the dataset with new observations hereafter. Our dataset will support scientists and experts in recognizing the status and dynamics of anuran assemblages in and around the evacuation zone and will contribute to the promotion of open science.

title: Fine-scale distribution of tropical seagrass beds in Southeast Asia

description: Southeast Asia is a hotspot of global seagrass diversity, offering valuable ecosystem services for human life. However, historically there have been large gaps in the scientific knowledge of the distribution of seagrass beds in this region. Information on the distribution has not been updated in global databases since the publication of the World Seagrass Atlas in 2003, which was based on data mostly obtained up until the late 1990s. We collected more recent data on seagrass bed distribution from 9 ASEAN countries plus southern China and southern Japan, and integrated these data into a GIS-database. A total of 1064 polygon data and 937 points data were uploaded in this paper, which were obtained from 107 scientific articles and reports published after 2000, including those written in local languages. Among them, 7.3 % of the data have associated information on seagrass bed size and 35.3 % have associated information on seagrass species composition. Data obtained from Vietnam, Cambodia, Singapore, Timor-Leste and Southern China cover almost all the coastlines of each country, whereas data for the Philippines, Indonesia, Malaysia Myanmar, Thailand still have large gaps in areal coverage. The data set has a few points from Brunei Darussalam, the Paracel Islands, Spratly Islands and Pratas Islands, which are areas that we lacked information on for a long time. The obtained data will be useful to understand the current status of seagrass beds and to help facilitate better conservation and management of coastal areas in this region.

title: Specimen-based records of geometrid, pyralid, and crambid moths (Lepidoptera) with location information from the collection of Dr. Hiroshi Inoue

description: As moths of the geometrid group usually live in forests and do not move long distances, they are considered to be valuable as environmental bio-indicators. Biodiversity data based on voucher specimens should have high quality and reliability. Here, we publish the records of the family Geometridae and the superfamily Pyraloidea (Pyralidae and Crambidae) with time of collection and location information, i.e., latitude and longitude on the basis of the collection of Dr. Hiroshi Inoue deposited at Institute for Agro-Environmental Sciences, NARO (NIAES). The collection of Geometridae covers 653 records from 615 species, collected from 1926 to 1979. The collection of Pyraloidea covers 447 records from 418 species, collected from 1949 to 1985. For the purpose, all users can access the data from the GBIF portal site with open data license CC BY 4.0; all data is published in the Global Biodiversity Information Facility (GBIF) through the Japan node of GBIF (JBIF).

title: Traits database of tidal flat macrobenthos along the Northwest Pacific coast of Japan

description: We collected information on the functional traits of the macrobenthos that inhabit mainly tidal flats along the Northwest Pacific coast of Tohoku, Japan, based on the species that were present during a survey after the Great East Japan Earthquake of 2011. The dataset contains information on 33 traits of 246 species and includes their taxonomic position, distribution, body length, habitat, reproduction type, and other characteristics such as diet type, migratory type, and invasiveness. Information about most basic traits such as body length, distribution, and habitat characteristics is complete, and more than 50% of trait information is complete for over 100 species, but information about reproduction is relatively limited. Although we did not limit our study to specific taxa and even included vegetation in the database, the majority of the taxa are Arthropoda, Mollusca, and Annelida. This file also has a table that compares the traits data to the existing traits database BIOTIC (Biological Traits Information Catalogue) to facilitate transformation and reuse of the data. Because the area of this survey was very adversely impacted by the Great East Japan Earthquake and Tsunami of 11 March 2011 and by post-disaster anthropogenic activities, this database will be relevant to assessments of post-disaster changes of the benthic community due to both the tsunami and human activities. The database is expected to fill the gap between the identification of species and assessments of community composition.

title: Assessing insect herbivory on broadleaf canopy trees at 19 natural forest sites across Japan

description: We present the largest freely available herbivory dataset for Japan representing data collected from a network of 19 natural forest sites across the country. Sampled network sites were part of the Monitoring Sites 1000 Project organized by the Ministry of the Environment. Sites were located across a range of climate zones, from subarctic to subtropical, and broadleaf trees (both evergreen and deciduous) were targeted at each site. Litterfall traps were used to assess leaf damage caused by leaf-chewing insects in 2014 and 2015. Using a standardized protocol, we assessed herbivory on 117,918 leaves of 39 dominant tree species. Preliminary analyses suggest that insect herbivory increases with increasing latitude for deciduous broadleaf species. In particular, oak (Quercus crispula) and beech (Fagus crenata) were subject to increased insect herbivory with increasing latitude. In contrast, insect herbivory decreased with increasing latitude in evergreen broadleaf species. The latitudinal gradient of herbivory differed according to leaf type (i.e., evergreen or deciduous). This dataset offers excellent opportunities for meta-analysis and comparative studies of herbivory among various forest types.

title: Fact database of grassland vegetation in Japan

description: This data paper reports vegetation census data collected in a network of 28 grassland sites in Japan. This is the largest grassland data set freely available in Japan. The network is the project “Grassland Dynamics in Japan” launched by the Ministry of the Agriculture and Forestry and Fisheries, Japan. It consists of semi-natural and artificial grasslands (pasture and meadow) and covers from Hokkaido to Kyushu area in Japan. Twenty to twelve permanent plots were established in each grassland. Censuses of plant species emerged in 1m2 quadrat were conducted every year from 1972 to 1982 at longest. The data provide species abundance, plant coverage (%) and length (cm) of 484 quadrats. The censuses adopted common census protocol, which provide good opportunities for meta-analyses and comparative studies among grasslands. The data have been used for ecological studies as well as for animal production reports published by the National Agriculture and Food Research Organization in Japan.
