Data from: The release rate of environmental DNA from juvenile and adult fish

Atsushi Maruyama, Keisuke Nakamura, Hiroki Yamanaka, Michio Kondoh & Toshifumi Minamoto
The environmental DNA (eDNA) technique is expected to become a powerful, non-invasive tool for estimating the distribution and biomass of organisms. This technique was recently shown to be applicable to aquatic vertebrates by collecting extraorganismal DNA floating in the water or absorbed onto suspended particles. However, basic information on eDNA release rate is lacking, despite it being essential for practical applications. In this series of experiments with bluegill sunfish (Lepomis macrochirus), we examined the effect...

Data from: Testing a “genes-to-ecosystems” approach to understanding aquatic-terrestrial linkages

Gregory Crutsinger, Seth Rudman, Mariano Rodriguez-Cabal, Athena Mckown, Takuya Sato, Andrew M. MacDonald, Julian Heavyside, Armando Geraldes, Edmund Hart, Carri LeRoy, Rana El-Sabaawi, Athena D. McKown, Gregory M. Crutsinger, Seth M. Rudman, Mariano A. Rodriguez-Cabal, Edmund M. Hart, Carri J. LeRoy & Rana W. El-Sabaawi
A ‘genes-to-ecosystems’ approach has been proposed as a novel avenue for integrating the consequences of intraspecific genetic variation with the underlying genetic architecture of a species in order to shed light on the relationships among hierarchies of ecological organization (genes [RIGHTWARDS ARROW] individuals [RIGHTWARDS ARROW] communities [RIGHTWARDS ARROW] ecosystems). However, attempts to identify genes with major effect on the structure of communities and/or ecosystem processes have been limited and a comprehensive test of this approach...

Data from: Morphological integration and pleiotropy in the adaptive body shape of the snail-feeding carabid beetle Damaster blaptoides

Junji Konuma, Satoshi Yamamoto & Teiji Sota
The snail-feeding carabid beetle Damaster blaptoides exhibits diverse head and thorax morphologies, and these morphotypes are linked with two alternative feeding behaviors. Stout-shaped beetles feed on snails by crushing the shells, whereas slender-shaped beetles consume snails by inserting their heads into the shells. A trade-off exists between these feeding strategies. Because intermediate-shaped beetles are less proficient in these two behaviors, stout-slender morphological divergence occurs between related species feeding on land snails. To examine the genetic...

Data from: Pushing the limits to tree height: could foliar water storage compensate for hydraulic constraints in Sequoia sempervirens

Hiroaki Ishii, Wakana Azuma, Keiko Kuroda, Stephen C. Sillett & H. Roaki Ishii
1. The constraint on vertical water transport is considered an important factor limiting height growth and maximum attainable height of trees. Here we show evidence of foliar water storage as a mechanism that could partially compensate for this constraint in Sequoia sempervirens, the tallest species. 2. We measured hydraulic and morpho-anatomical characteristics of foliated shoots of tall S. sempervirens trees near the wet, northern and dry, southern limits of its geographic distribution in California, USA....
