Data from: BCI training to move a virtual hand reduces phantom limb pain: a randomized crossover trial

Takufumi Yanagisawa, Ryohei Fukuma, Ben Seymour, Masataka Tanaka, Koichi Hosomi, Okito Yamashita, Haruhiko Kishima, Yukiyasu Kamitani & Youichi Saitoh
Objective: To determine whether training with a brain–computer interface (BCI) to control an image of a phantom hand, which moves based on cortical currents estimated from magnetoencephalographic signals, reduces phantom limb pain. Methods: Twelve patients with chronic phantom limb pain of the upper limb due to amputation or brachial plexus root avulsion participated in a randomized single-blinded crossover trial. Patients were trained to move the virtual hand image controlled by the BCI with a real...

Phosphorus allocation to and resorption from leaves regulate the residence time of phosphorus in aboveground forest biomass on Mount Kinabalu, Borneo

Yuki Tsujii, Shin-Ichiro Aiba & Kanehiro Kitayama
1. The residence time of phosphorus (P) in trees is a consequence of plant adaptation to P deficiency, with longer P residence time on soils with low P availability. P residence time has been studied at the leaf or canopy level but seldom at the whole-tree level. Whereas P residence time at the leaf or canopy level is largely determined by leaf longevity and the resorption of P before leaf abscission, P residence time at...

Data from: Estimating fish population abundance by integrating quantitative data on environmental DNA and hydrodynamic modeling

Keiichi Fukaya, Hiroaki Murakami, Seokjin Yoon, Kenji Minami, Yutaka Osada, Satoshi Yamamoto, Reiji Masuda, Akihide Kasai, Kazushi Miyashita, Toshifumi Minamoto & Michio Kondoh
Molecular analysis of DNA left in the environment, known as environmental DNA (eDNA), has proven to be a powerful and cost-effective approach to infer occurrence of species. Nonetheless, relating measurements of eDNA concentration to population abundance remains difficult because detailed knowledge on the processes that govern spatial and temporal distribution of eDNA should be integrated to reconstruct the underlying distribution and abundance of a target species. In this study, we propose a general framework of...

Non-adaptive host-use specificity in tropical armored scale insects

Nate B. Hardy, Daniel Peterson, Geoffrey Morse, Takao Itioka, Jiufeng Wei & Benjamin Normark
Most herbivorous insects are diet specialists in spite of the apparent advantages of being a generalist. This conundrum might be explained by fitness trade-offs on alternative host plants, yet evidence of such trade-offs has been elusive. Another hypothesis is that specialization is non-adaptive, evolving through neutral population genetic processes and within the bounds of historical constraints. Here we report on a striking lack of evidence for the adaptiveness of specificity in tropical canopy communities of...

Interspecific social dominance networks reveal mechanisms promoting coexistence in sympatric charrs in Hokkaido, Japan

Kurt Fausch, Shigeru Nakano, Satoshi Kitano, Yoichiro Kanno & Seoghyun Kim
1. Coexistence of species requires equalizing mechanisms that minimize fitness differences, which are balanced by stabilizing mechanisms that enhance negative intraspecific interactions versus interspecific ones. Here, we develop a simple theoretical framework that allows measuring the relative strength of intraspecific versus interspecific competition in dominance hierarchies. We use it to evaluate mechanisms promoting coexistence between congeneric charrs that compete for foraging positions, which strongly influence density-dependent growth and survival. 2. Agonistic interactions (n = 761)...
