Fish–prey interactions in, and associated data from, a temperate stream of the Yura River, Kyoto, Japan

Although quantitative data on interspecific interactions within complex food webs are essential for evaluation of assumptions, hypotheses, and predictions of ecological theories; empirical studies yielding quantitative data on complex food webs are very limited. Ecological information on body size, habitat use, and seasonality of the component species of food webs aids in...

Image dataset of ophiuroid and other deep sea benthic organisms in 2015 extracted from the survey off Sanriku, Japan, by the research following the Great East Japan Earthquake 2011

This is the first large image dataset and occurrence records of marine organisms in the Northwest Pacific off Tohoku, Japan. This area suffered by Great East Japan Earthquake 2011 and continental shelf and slope off of this area considered one of the most productive areas both for fishery and primary production in the world because of the complex mixture of the Kuroshio Current...

Ecological consideration for several methodologies to diagnose vegetation phenology

A challenge of phenological research is to integrate remotely sensed observations obtained at different spatial and temporal scales to provide information that contains both a high temporal density and fine spatial scale observations. This study aims to improve the level of spatial detail and the temporal density required for efficient monitoring of vegetation phenology by...

Long-term data on forest regeneration after catastrophic windthrow in Tomakomai, Hokkaido, northern Japan

Typhoon No. 15 in 1954 (Marie) caused catastrophic windthrow in Hokkaido, northern Japan. The Tomakomai District of the National Forest was one of the forests severely damaged. A study site was established in a stand of the National Forest within the jurisdiction of the Iburi East District Forest Office. The stand was located on the eastern slope of Mt. Tarumae at an elevation of...

Nickel hyperaccumulation in Antidesma montis-silam: from herbarium discovery to collection in the native habitat

The majority of nickel hyperaccumulator plant species have been discovered by screening using a field spot test based on dimethylglyoxime. Recently, the use of a portable X-ray fluorescence spectroscopy instruments has enabled non-destructive analyses of existing herbarium collections. Given that the family Phyllanthaceae globally has the greatest numbers of hyperaccumulators...

Changed land management policy and the emergence of a novel forest ecosystem in South Korea: landscape dynamics in Pohang over 90 years

Ecosystem management in South Korea dramatically changed in the early 1970s, shifting from historical utilization of natural resources to a strong management system that included forest promotion and restoration. The socio-economic and biological context underpinning this effort and the ecological consequences of this new policy have not been studied in South Korea. We analyzed...

Plant–soil interactions maintain biodiversity and functions of tropical forest ecosystems

Tropical forests are characterized by high biodiversity and aboveground biomass growing on strongly weathered soils. However, the distribution of plant species and soils are highly variable even within a tropical region. This paper reviews existing and novel knowledge on soil genesis, plant and microbial physiology, and biogeochemistry. Typically, forests in Southeast Asia are...

Beauty alone is insufficient: female mate choice in the barn swallow

The barn swallow, Hirundo rustica, is a model species for studying sexual selection, particularly female mate choice. Although there have already been several reviews of female mate choice and its geographic variation in this species, all of them have focused on secondary sexual characteristics. Here, for better understanding of the general pattern of female mate choice and their...

Long-term zooplankton community records (1996–2017) for Lake Suwa (Japan)

The impact of eutrophication on aquatic ecosystems remains an important topic in aquatic ecology; however, recent successes in water quality restoration in highly eutrophicated water bodies present new research potential regarding re-oligotrophication. Successfully reducing nutrient loading from sewage treatment through restoration activities, induces large changes in...

Crossing boundaries: Shigeru Nakano’s enduring legacy for ecology

Shigeru Nakano was a Japanese ecologist whose work crossed boundaries among subdisciplines in ecology, between aquatic and terrestrial habitats, and between different languages and cultures. He published his first paper in 1985 while still an undergraduate, and is well known for his early research on the individual behavior of stream salmonids in dominance hierarchies. Shortly...

Filling the gaps in ecological studies of socioecological systems

Our human-dominant world can be viewed as being built up in two parts, social and ecological systems, each consisting of multi-level organizations that interact in a complex manner. However, there are knowledge gaps among those interactions. In this paper, we focus on studies filling two types of gaps in the socioecological system, some of which are case studies in the East Asia...

The soil seed bank of a rehabilitated draw-down zone and its similarity to standing vegetation in the Three Gorges Reservoir Area

The reverse seasonal flooding that resulted from the construction of the Three Gorges Project has induced a drastic degradation of draw-down zone vegetation and the seed bank in the reservoir. The composition and distribution of seed banks and their similarities to standing vegetation were determined through field investigations and germination experiments on the vegetation as...

Aerial images can detect 3D small patch reefs that are potential habitats for anemonefish Amphiprion frenatus

Patchy habitats often enhance species coexistence and, consequently, abundance of each species. The present study examined two indicators of potential habitats for anemonefish Amphiprion frenatus: total area of dark-colored patch reefs that are detectable on an aerial image with image analysis software, and total area of tall patch reefs (>1.5 m in height) that are detectable on...

Recent developments in understanding mast seeding in relation to dynamics of carbon and nitrogen resources in temperate trees

Mast seeding, the synchronous intermittent production of large seed crops in populations of perennial plants, is a widespread and widely studied phenomenon. Economy of scale has been demonstrated to provide the ultimate selection factor driving the evolution of masting, for example, in terms of the predator-satiation and pollination-efficiency hypotheses; however, its...

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

Large-scale land abandonment and reconstruction activity has altered the ecosystem structure in the evacuation area for the Fukushima Daiichi power plant accident in 2011. Despite social concerns about changes in the avian assemblages that occurred after the accident, publicly accessible data are quite limited. We engaged in acoustic monitoring of birds using digital voice...

Phytoplankton species abundance in Lake Inba (Japan) from 1986 to 2016

Lake Inba is one of the most eutrophic lakes in Japan. This data paper reports the abundance of phytoplankton species sampled biweekly from April 1986 to March 2016 at four stations in Lake Inba. Monitoring has been carried out by Chiba Prefectural Government, and phytoplankton count data have been collected since 1986. A total of 340 phytoplankton species were identified and...

Empirical dynamic modeling for beginners

Natural systems are often complex and dynamic (i.e. nonlinear), making them difficult to understand using linear statistical approaches. Linear approaches are fundamentally based on correlation. Thus, they are ill-posed for dynamical systems, where correlation can occur without causation, and causation may also occur in the absence of correlation. “Mirage correlation” (i.e., the...

Native Mediterranean plants as potential food sources for natural enemies of insect pests in olive groves

The diversity of native non-crop (weed) vegetation in agricultural landscapes can provide arthropod natural enemies with food sources and shelter, thus improving natural pest control and reducing dependence on chemical pesticides. Moreover, native plants to a region are uniquely positioned to provide cultural ecosystem services such as wild food and wild medicinal plants, as well...

Genome-wide population genetic analysis identifies evolutionary forces establishing continuous population divergence

Elucidating the mechanism shaping the spatial variations of traits has long been a central concern of evolutionary biologists. Geographic clines of allele/morph frequencies along environmental gradients are suggested to be established and maintained by the balancing of two opposing evolutionary forces, namely selection that generates spatial differentiation in morph frequencies...
