Yeai Zou, Feng Zhu, Ye-Ai Zou, Pingyang Zhang, Siqi Zhang, Xinsheng Chen, Feng Li, Zhengmiao Deng, Hong Zhang, Zhibing Yu, Xiaoyong Zhu, Yonghong Xie & Dongsheng Zou
Dongting Lake, an important wintering habitat for migratory waterbirds in the East Asian–Australasian Flyway, has suffered serious degradation in recent decades. To restore habitats for biodiversity conservation and flood control, 459 dykes were demolished and 14 were preserved in 2017. However, the direct impact of dyke demolition on wintering waterbirds was not comprehensively assessed. In this study, based on annual waterbird census and habitat data (2013/14–2020/21), we compared the differences in habitat areas and species...

Data from: Population genetic structure and connectivity of deep-sea stony corals (Order Scleractinia) in the New Zealand region: implications for the conservation and management of Vulnerable Marine Ecosystems

Cong Zeng, Ashley A. Rowden, Malcolm R. Clark, Jonathan P.A. Gardner & Jonathan P. A. Gardner
Deep-sea stony corals, which can be fragile, long-lived, late to mature and habitat-forming, are defined as vulnerable marine ecosystem indicator taxa. Under United Nations resolutions these corals require protection from human disturbance such as fishing. To better understand the vulnerability of stony corals (Goniocorella dumosa, Madrepora oculata, Solenosmilia variabilis) to disturbance within the New Zealand region, and to guide marine protected area design, genetic structure and connectivity were determined using microsatellite loci and DNA sequencing....

Data from: Morphological responses of two plant species from different elevations in the Dongting Lake wetlands, China, to variation in water levels

Youzhi Li, Hualin Bian, Bo Ren, Yonghong Xie, Xiaohui Ding, Xin Yao & Qiaoqiao Zhou
Plants show strong zonation patterns in wetlands. Nevertheless, the mechanisms determining these patterns remain unclear. In the present study, growth and morphological responses to a water level gradient [-20 cm (i.e., water level 20 cm below soil surface), -10 cm, 0 cm, 10 cm, 20 cm] were compared between a higher elevation plant (Imperata cylindrica) and a lower elevation plant (Carex brevicuspis) in the Dongting Lake wetlands of China. The aboveground, belowground, and total biomass...

Data from: New insights on water buffalo genomic diversity and post-domestication migration routes from medium density SNP chip data

Licia Colli, Marco Milanesi, Elia Vajana, Daniela Iamartino, Lorenzo Bomba, Francesco Puglisi, Marcello Del Corvo, Ezequiel Luis Nicolazzi, Sahar Saad El-Din Ahmed, Jesus Rommel V. Herrera, Libertado Cruz, Shuju Zhang, Aixin Liang, Gouhua Hua, Ligou Yang, Xingjie Hao, Fuyuan Zuo, Song-Jia Lai, Shuilian Wang, Ruyu Liu, Yundeng Gong, Mahdi Mokhber, Yongjiang Mao, Feng Guan, Augustin Vlaic … & Liguo Yang
The domestic water buffalo is native to the Asian continent but through historical migrations and recent importations, nowadays has a worldwide distribution. The two types of water buffalo, i.e., river and swamp, display distinct morphological and behavioral traits, different karyotypes and also have different purposes and geographical distributions. River buffaloes from Pakistan, Iran, Turkey, Egypt, Romania, Bulgaria, Italy, Mozambique, Brazil and Colombia, and swamp buffaloes from China, Thailand, Philippines, Indonesia and Brazil were genotyped with...

Biometric conversion factors as a unifying platform for comparative assessment of invasive freshwater bivalves

Neil Coughlan, Eoghan Cunningham, Ross Cuthbert, Patrick Joyce, Pedro Anastacio, Filipe Banha, Nicolás Bonel, Stephanie Bradbeer, Elizabeta Briski, Vincent Butitta, Zuzana Čadková, Jaimie Dick, Karel Douda, Lawrence Eagling, Noé Ferreira-Rodríguez, Leandro Hünicken, Mattias Johansson, Louise Kregting, Anna Labecka, Deliang Li, Florencia Liquin, Jonathan Marescaux, Todd Morris, Patrycja Nowakowska, Małgorzata Ożgo … & Francisco Sylvester
1. Invasive bivalves continue to spread and negatively impact freshwater ecosystems worldwide. As different metrics for body size and biomass are frequently used within the literature to standardise bivalve related ecological impacts (e.g. respiration and filtration rates), the lack of broadly applicable conversion equations currently hinders reliable comparison across bivalve populations. To facilitate improved comparative assessment amongst studies originating from disparate geographic locations, we report body size and biomass conversion equations for six invasive freshwater...

Data from: Predicting rice hybrid performance using univariate and multivariate GBLUP models based on North Carolina mating design II

X. Wang, L. Li, Z. Yang, X. Zheng, S. Yu, C. Xu & Z. Hu
Genomic selection (GS) is more efficient than traditional phenotype-based methods in hybrid breeding. The present study investigated the predictive ability of genomic best linear unbiased prediction models for rice hybrids based on the North Carolina mating design II, in which a total of 115 inbred rice lines were crossed with 5 male sterile lines. Using 8 traits of the 575 (115 × 5) hybrids from two environments, both univariate (UV) and multivariate (MV) prediction analyses,...

Data from: The whitefly-associated facultative symbiont Hamiltonella defensa suppresses induced plant defences in tomato

Qi Su, Kerry M. Oliver, Wen Xie, Qingjun Wu, Shaoli Wang & Youjun Zhang
1. Maternally inherited bacterial symbionts are present in many, if not most, insect species. While there is rapidly accumulating evidence that facultative, heritable symbionts often protect insect hosts from natural enemies, there have been few clear examples where facultative symbionts mediate herbivore–plant interactions. 2. The phloem-feeding whitefly, Bemisia tabaci, is a major agricultural pest that frequently harbours facultative symbionts, including Hamiltonella defensa. While H. defensa and other facultative symbionts have been shown to improve whitefly...

Data from: Whitefly aggregation on tomato is mediated by feeding-induced changes in plant metabolites that influence the behavior and performance of conspecifics

Qi Su, Gong Chen, Mark C. Mescher, Zhengke Peng, Wen Xie, Shaoli Wang, Qingjun Wu, Jie Liu, Chuanren Li, Wenkai Wang & Youjun Zhang
1.Leaf damage caused by herbivore feeding often triggers induced resistance in plants. However, some herbivores can take advantage of the resulting metabolic changes in host plants and may even manipulate plant resistance, leading to a phenomenon known as induced susceptibility. 2.Previous work has shown that feeding by the whitefly Bemisia tabaci can reduce tomato Solanum lycopersicum resistance and that whiteflies tended to aggregate on infested plants. However, metabolomic changes in the plant and associated whitefly...

Data from: Mitochondrial genome fragmentation unites the parasitic lice of eutherian mammals

Fan Song, Hu Li, Guo-Hua Liu, Wei Wang, Peter James, Douglas D. Colwell, Anette Tran, Siyu Gong, Wanzhi Cai & Renfu Shao
Organelle genome fragmentation has been found in a wide range of eukaryotic lineages; however, its use in phylogenetic reconstruction has not been demonstrated. We explored the use of mitochondrial (mt) genome fragmentation in resolving the controversial suborder-level phylogeny of parasitic lice (order Phthiraptera). There are ~5,000 species of parasitic lice in four suborders (Amblycera, Ischnocera, Rhyncophthirina and Anoplura), which infest mammals and birds. The phylogenetic relationships among these suborders are unresolved despite decades of studies....

Mountain biodiversity and ecosystem functions: Interplay between geology and contemporary environments

Ang Hu
Although biodiversity and ecosystem functions are strongly shaped by contemporary environments such as climate and local biotic and abiotic attributes, relatively little is known about how they depend on long-term geological processes. Here, along a 3000-m elevational gradient with tectonic faults on the Tibetan Plateau, we studied the joint effects of geological and contemporary environments on biological communities, such as the diversity and community composition of plants and soil bacteria, and ecosystem functions. We found...
