From nature reserve to mosaic management: improving matrix survival, not permeability, benefits regional populations under habitat loss and fragmentation

Yuichi Yamaura, Robert Fletcher, Steven Lade, Motoki Higa & David Lindenmayer
Although matrix improvement in fragmented landscapes is a promising conservation measure, matrix permeability (willingness of an organism to enter the matrix) and movement survival in the matrix are usually aggregated. Consequently, it is unknown which matrix property needs to be improved. It also remains unclear whether matrix upgrading from dispersal passage to providing reproduction opportunities has large conservation benefits and whether there are interactive effects between habitat and matrix management. We examined matrix effects on...

Verification of the accuracy of the recent 50 years of tree growth and long-term change in intrinsic water-use efficiency using xylem Δ14C and δ13C in trees in an aseasonal tropical rainforest

Tomoaki Ichie, Shuichi Igarashi, Ryo Yoshihara, Kanae Takayama, Tanaka Kenzo, Kaoru Niiyama, Nur Hajar Zamah Shari, Fujio Hyodo & Ichiro Tayasu
Growth analysis based on tree-ring chronology is difficult in trees in aseasonal tropical rain forests, because annual growth rings may be unclear or completely absent. Fortunately, tree growth history recorded in xylem tissue is capable of providing valuable information on the responses of trees and forests to past and present environmental changes, including global warming. We have developed a new technique for aseasonal tropical forest trees which derives their growth rates from xylem Δ14C, and...

Nonlinear time series analysis of the interaction between the citrus whitefly and the whitefly-specialist ladybird

Suzuki Noriyuki, Kazutaka Kawatsu & Shuji Kaneko
A comprehensive understanding of the top-down effects of natural enemies on agricultural pests is essential for achieving effective biological control in integrated pest management. However, it is typically difficult to identify causal effects between the interacting species from time series data, which have often been monitored for pest forecasting purposes in agricultural ecosystems, as it is likely to involve nonlinear (state-dependent) population dynamics. In this study, we applied a recently developed framework of nonlinear time...

Semi‐quantitative metabarcoding reveals how climate shapes arthropod community assembly along elevation gradients on Hawaii Island

Jun Ying Lim, Jairo Patiño, Suzuki Noriyuki, Henrik Krehenwinkel, Luis Simmari, Rosemary Gillespie, Luis Cayetano & Rosemary G. Gillespie
Spatial variation in climatic conditions along elevation gradients provides an important backdrop by which communities assemble and diversify. Lowland habitats tend to be connected through time, whereas highlands can be continuously or periodically isolated, conditions that have been hypothesized to promote high levels of species endemism. This tendency is expected to be accentuated among taxa that show niche conservatism within a given climatic envelope. While species distribution modeling approaches have allowed extensive exploration of niche...

Raw data for the samples collected from Hole B of the ICDP DSeis project at the Moab Khotsong Gold Mine in South Africa

Takeshi Miyamoto, Tetsuro Hirono, Yuki Yokoyama, Shunya Kaneki, Yuhji Yamamoto, Tsuyoshi Ishikawa, Akira Tsuchiyama, Ikuo Katayama, Yasuo Yabe, Martin Ziegler, Raymond Durrheim & Hiroshi Ogasawara
This data set is corresponding to the Miyamoto, T. et al. “Characteristics of Seismogenic Fault Rock Related to the 2014 Orkney Earthquake (M5.5) Beneath the Moab Khotsong Gold Mine, South Africa” Geophysical Research Letters, 2022. This data set shows physical property, magnetic susceptibility, mineral assemblage, and element composition of all Hole B subsamples, and frictional properties of 5 Hole B subsamples.
