Impact of upwelling on phytoplankton blooms and hypoxia along the Chinese coast in the East China Sea

Chung-Chi Chen, Fuh-Kwo Shiah, Gwo-Ching Gong & Tzong-Yueh Chen
This study evaluates the rarely observed phenomenon of the simultaneous occurrences of phytoplankton blooms, hypoxia, and upwelling along the Zhejiang coast in the East China Sea. Results show that the upwelling uplifted bottom water to 5–10 m below the surface. In the upwelling region, phytoplankton blooms (Chl a = 10.9 μg L−1) occurred and hypoxia or low-oxygen appeared below the surface water. High concentrations of nitrate and phosphate were regenerated in the hypoxic regions, corresponding...

Seasonal rainfall in subtropical montane cloud forests drives demographic fluctuations in a Green-backed Tit population

Ming-Tang Shiao, Mei-Chen Chuang, Hsiao-Wei Yuan & Ying Wang
Montane birds are vulnerable to climate change. However, the mechanisms by which weather drives demographic processes in montane birds have seldom been investigated. We conducted a long-term study (2009–2019) on the Green-backed Tit (Parus monticolus), an insectivorous passerine, in the montane cloud forest of subtropical Taiwan. We explored the effects of weather variability on the productivity and survival of adult Green-backed Tits. Nest survival was negatively associated with seasonal rainfall during the breeding season (April–July)...

Riding an escalator: upward range shift and patterns of genetic response to climate change in Acer caudatifolium

Min-Wei Chai, Yi-Ting Tseng, Hsin-Pei Lu, Min-Xin Luo, Jui-Tse Chang & Pei-Chun Liao
Aim Rapid global warming is threatening global biodiversity, and it will likely lead to varying degrees of local adaptation, particularly among plant species. Besides, rising temperatures frequently result in upslope distribution shifts towards climatic optima (i.e., the escalator effect) within a limited dispersal space, such as in insular environments. Here, we integrated ecological and genetic approaches to investigate how climate change will impact the genetic compositions and spatial distributions of Taiwan endemic maple Acer caudatifolium....

Morphological and isotope data on three passerines in Taiwan

Pei-Jen Shaner & Yu‐Cheng Hsu
The niche variation hypothesis (NVH) predicts that populations with wider niches exhibit greater morphological variation through increased inter-individual differences in both niche and morphology. In this study, we examined niche-trait relationships in three passerine species (Cyanoderma ruficeps, Sinosuthora webbiana, Zosterops simplex). A total of 289 C. ruficeps from 7 sites, 259 S. webbiana from 8 sites, and 144 Z. simplex from 6 sites were sampled along an elevation gradient (0-2,700 m) in Taiwan from 2009...

Data from: Large ecosystem service benefits of assisted natural regeneration

Yusheng Yang, Lixin Wang, Zhijie Yang, Chao Xu, Jingsheng Xie, Guangshui Chen, Chengfang Lin, Jianfen Guo, Xiaofei Liu, Decheng Xiong, Weisheng Lin, Shidong Chen, Zongming He, Kaimiao Lin, Miaohua Jiang & Teng-Chiu Lin
China manages the largest monoculture plantations in the world, with 24% being Chinese fir plantations. Maximizing the ecosystem services of Chinese fir plantations has important implications in global carbon cycle and biodiversity protection. Assisted natural regeneration (ANR) is a practice to convert degraded lands into more productive forests with great ecosystems services. However, the quantitative understanding of ANR ecosystem service benefits is very limited. We conducted a comprehensive field manipulation experiment to evaluate the ANR...

Data from: Litter type and termites regulate root decomposition across contrasting savanna land-uses

Stuart W. Smith, James D. M. Speed, John Bukombe, Shombe N. Hassan, Richard D. Lyamuya, Philipo Jacob Mtweve, Anders Sundsdal & Bente J. Graae
Decomposition is a vital ecosystem process, increasingly modified by human activity. Theoretical frameworks and empirical studies that aim to understand the interplay between human land-use, macro-fauna and decomposition processes have primarily focused on leaf and wood litter. For a whole-plant understanding of how land-use and macro-fauna influence decomposition, investigating root litter is required. Using litterbags, we quantified rates of root decomposition across contrasting tropical savanna land-uses, namely wildlife and fire-dominated protected areas and livestock pastureland...

Data from: Fighting experience alters brain androgen receptor expression dependent on testosterone status

Cheng-Yu Li, Ryan L. Earley, Shu-Ping Huang, Yuying Hsu, S.-P. Huang & C.-Y. Li
Contest decisions are influenced by the outcomes of recent fights (winner–loser effects). Steroid hormones and serotonin are closely associated with aggression and therefore probably also play important roles in mediating winner–loser effects. In mangrove rivulus fish, Kryptolebias marmoratus, individuals with higher testosterone (T), 11-ketotestosterone and cortisol levels are more capable of winning, but titres of these hormones do not directly mediate winner–loser effects. In this study, we investigated the effects of winning/losing experiences on brain...

Population genetics under the Massenerhebung effect: the influence of topography on the demography of Acer morrisonense (Sapindaceae)

Jui-Tse Chang, Min-Xin Luo, Hsin-Pei Lu, Yi-Ting Tseng & Pei-Chun Liao
Aim: The Massenerhebung effect (Mass elevation effect) refers to heat or wind-driven altitudinal distribution patterns of temperature-dependent parameters among massifs with narrower range and lower elevation around peripheral and isolated mountains compared to core and continuous ones. Although common in ecology, this effect is rarely discussed in population genetics. Here, we use genetic markers to reveal population genetic patterns and also test the mountain- and sky-barrier hypotheses relevant to the Massenerhebung distribution pattern of Acer...

Eggs survive through avian guts—A possible mechanism for transoceanic dispersal of flightless weevils

Hui-Yun Tseng, Si‐Min Lin, Tsui‐Wen Li, Chia‐Hsin Liou, Ace Kevin S. Amarga & Analyn Cabras
How flightless animals disperse to remote oceanic islands is a key unresolved question in biogeography. The flightless Pachyrhynchus weevils represent repetitive colonization history in West Pacific islands, which attracted our interests about how some weevils have successfully dispersed in the reverse direction against the sea current. Here, we propose endozoochory as a possible mechanism that the eggs of the weevils might be carried by embedded in the fruits as the food of frugivorous birds. In...

Data from: Population genetic structure, local adaptation, and conservation genetics of Kandelia obovata

Yu Ruan, Bing-Hong Huang, Shih-Jie Lai, Yu-Ting Wan, Jun-Qing Li, Shong Huang & Pei-Chun Liao
Topographic changes during the Pleistocene glacial/interglacial cycles affected the distribution of coastline mangroves and influenced their population genetic structure. The submergence of the continental shelf off southeast China during the postglacial age caused coastline expansions and resulted in the colonization of mangroves. Here, we performed multilocus genome scans using amplified fragment-length polymorphisms to explore the effects of topography and natural selection in structuring Kandelia obovata populations. Long-term isolation by the Taiwan Strait since the end...

Data from: Community structure influences species’ abundance along environmental gradients

Antti P. Eloranta, Ingeborg P. Helland, Odd Terje Sandlund, Trygve Hesthagen, Ola Ugedal & Anders G. Finstad
Species response to abiotic environmental variation can be influenced by local community structure and interspecific interactions, particularly in restricted habitats such as islands and lakes. In temperate lakes, future increase in water temperature and runoff of terrestrial (allochthonous) dissolved organic carbon (DOC) are predicted to alter community composition and the overall ecosystem productivity. However, little is known about how the present community structure and abiotic environmental variation interact to affect the abundance of native fish...

Data from: Climate niche differentiation between two passerines despite ongoing gene flow

Shou-Hsien Li, Pei-Jen L. Shaner, Tzu-Hsuan Tsao, Rong-Chien Lin, Wei Liang, Chia-Fen Yeh, Xiao-Jun Yang, Fu-Min Lei, Fang Zhou, Can-Chao Yang & Yu-Cheng Hsu
Niche evolution underpins the generation and maintenance of biological diversity, but niche conservatism, in which niches remain little changed over time in closely related taxa and the role of ecology in niche evolution are continually debated. To test whether climate niches are conserved in two closely related passerines in East Asia – the vinous-throated (Paradoxornis webbianus) and ashy-throated (P. alphonsianus) parrotbills – we established their potential allopatric and sympatric regions using ecological niche models and...

Data from: Reconstructing the invasion history of Heracleum persicum (Apiaceae) into Europe

Dilli P. Rijal, Torbjørn Alm, Šárka Jahodova, Hans K. Stenøein & Inger G. Alsos
Sparse, incomplete and inappropriate historical records of invasive species often hamper invasive species management interventions. Population genetic analyses of invaders might provide a suitable context for the identification of their source populations and possible introduction routes. Here, we describe the population genetics of Heracleum persicum Desf. ex Fisch and trace its route of introduction into Europe. Microsatellite markers revealed a significantly higher genetic diversity of H. persicum in its native range, and the loss of...

Data from: Highly overlapping winter diet in two sympatric lemming species revealed by DNA metabarcoding

Eeva M. Soininen, Gilles Gauthier, Frédéric Bilodeau, Dominique Berteaux, Ludovic Gielly, Pierre Taberlet, Galina Gussarova, Eva Bellemain, Kristian Hassel, Hans K. Stenøien, Laura Epp, Audun Schrøder-Nilsen, Christian Brochmann, Nigel G. Yoccoz & Audun Schrøder-Nielsen
Sympatric species are expected to minimize competition by partitioning resources, especially when these are limited. Herbivores inhabiting the High Arctic in winter are a prime example of a situation where food availability is anticipated to be low, and thus reduced diet overlap is expected. We present here the first assessment of diet overlap of high arctic lemmings during winter based on DNA metabarcoding of feces. In contrast to previous analyses based on microhistology, we found...

Data from: Genomic analysis of demographic history and ecological niche modeling in the endangered Sumatran Rhinoceros Dicerorhinus sumatrensis

, Chih-Ming Hung, Pei-Jen Shaner, James Denvir, Megan Justice, Shang-Fang Yang, Terri L. Roth, David A. Oehler, Jun Fan, Swanthana Rekulapally, Donald A. Primerano & Herman L. Mays
The vertebrate extinction rate over the past century is approximately 22–100 times greater than background extinction rates, and large mammals are particularly at risk. Quaternary megafaunal extinctions have been attributed to climate change, overexploitation, or a combination of the two. Rhinoceroses (Family: Rhinocerotidae) have a rich fossil history replete with iconic examples of climate-induced extinctions, but current pressures threaten to eliminate this group entirely. The Sumatran rhinoceros (Dicerorhinus sumatrensis) is among the most imperiled mammals...

Data from: Genetic relationships and ecological divergence in Salix species and populations in Taiwan

Chun-Lin Huang, Chung-Te Chang, Bing-Hong Huang, Jeng-Der Chung, Jui-Hung Chen, Yu-Chung Chiang & Shih-Ying Hwang
Linking ecology with evolutionary biology is important to understand how environments drive population and species divergence. Phenotypically diverse Salix species, such as lowland riparian willow trees and middle- to high-elevation multistemmed shrubs and alpine dwarf shrubs, provide opportunities for studying genetic divergence driven by ecological factors. We used amplified fragment length polymorphism (AFLP) to quantify the genetic variation of 185 individuals from nine populations of four Salix species in Taiwan. Our phylogenetic analyses distinguished two...

Data from: Divergent selection and local adaptation in disjunct populations of an endangered conifer, Keteleeria davidiana var. formosana (Pinaceae)

Jing-Yu Fang, Jeng-Der Chung, Yu-Chung Chiang, Chung-Te Chang, Chia-Ying Chen & Shih-Ying Hwang
The present study investigated the genetic diversity, population structure, FST outliers, and extent and pattern of linkage disequilibrium in five populations of Keteleeria davidiana var. formosana, which is listed as a critically endangered species by the Council of Agriculture, Taiwan. Twelve amplified fragment length polymorphism primer pairs generated a total of 465 markers, of which 83.74% on average were polymorphic across populations, with a mean Nei’s genetic diversity of 0.233 and a low level of...

Data from: Transitions in smartphone addiction proneness among children: the effect of gender and use patterns

Fong-Ching Chang, Jeng-Tung Chiang, Kun-Wei Lee & Szu-Yuan Hsu
Objectives This study assessed the incidence of transitions in smartphone addiction proneness (SAP) among children and examined the effects of gender, use patterns (social networking sites (SNSs) use and smartphone gaming) and depression on smartphone addiction transitions.Methods A representative sample of 2,155 children from Taipei completed longitudinal surveys in both 2015 (5th grade) and 2016 (6th grade). Latent transition analysis (LTA) was used to characterize transitions in SAP and to examine the effects of use...

Data from: Too hard to swallow: a secret secondary defence of an aposematic insect

Lu-Yi Wang, Wen-San Huang, Hsin-Chieh Tang, Lung-Chun Huang & Chung-Ping Lin
Anti-predator strategies are significant components of adaptation in prey species. Aposematic prey are expected to possess effective defences that have evolved simultaneously with their warning colours. This study tested the hypothesis of the defensive function and ecological significance of the hard body in aposematic Pachyrhynchus weevils pioneered by Alfred Russel Wallace nearly 150 years ago. We used predation trials with Japalura tree lizards to assess the survivorship of ‘hard’ (mature) vs. ‘soft’ (teneral) and ‘clawed’...

Data from: Historical connectivity, contemporary isolation, and local adaptation in a widespread but discontinuously distributed species, Rhododendron oldhamii, endemic to Taiwan

Shih-Ying Hwang, Y-C Hsieh, J-D Chung, C-N Wang, C-T Chang & C-Y Chen
Elucidation of the evolutionary processes that constrain or facilitate adaptive divergence is a central goal in evolutionary biology, especially in non-model organisms. We tested whether changes in dynamics of gene flow (historical vs contemporary) caused population isolation and examined local adaptation in response to environmental selective forces in fragmented Rhododendron oldhamii populations. Variation in 26 expressed sequence tag-simple sequence repeat loci from 18 populations in Taiwan was investigated by examining patterns of genetic diversity, inbreeding,...

Data from: Drivers of vegetative dormancy across herbaceous perennial plant species

Richard P. Shefferson, Tiiu Kull, Michael J. Hutchings, Marc-André Selosse, Hans Jacquemyn, Kimberly M. Kellett, Eric S. Menges, Richard B. Primack, Juha Tuomi, Kirsi Alahuhta, Sonja Hurskainen, Helen M. Alexander, Derek S. Anderson, Rein Brys, Emilia Brzosko, Slavomir Dostálik, Katharine Gregg, Zdeněk Ipser, Anne Jäkäläniemi, Jana Jersáková, W. Dean Kettle, Melissa K. McCormick, Ana Mendoza, Michael T. Miller, Asbjørn Moen … & Dennis F. Whigham
Vegetative dormancy, that is the temporary absence of aboveground growth for ≥ 1 year, is paradoxical, because plants cannot photosynthesise or flower during dormant periods. We test ecological and evolutionary hypotheses for its widespread persistence. We show that dormancy has evolved numerous times. Most species displaying dormancy exhibit life‐history costs of sprouting, and of dormancy. Short‐lived and mycoheterotrophic species have higher proportions of dormant plants than long‐lived species and species with other nutritional modes. Foliage...

Data from: Age-dependent trajectories differ between within-pair and extra-pair paternity success

Yu-Hsun Hsu, Mirre J. P. Simons, Julia Schroeder, Antje Girndt, Isabel S. Winney, Terry Burke, Shinichi Nakagawa & Y.-H. Hsu
Reproductive success is associated with age in many taxa, increasing in early life followed by reproductive senescence. In socially monogamous, but genetically polygamous species, this generates the interesting possibility of differential trajectories of within-pair and extra-pair siring success with age in males. We investigate these relationships simultaneously using within-individual analyses with 13 years of data from an insular house sparrow (Passer domesticus) population. As expected, we found that both within- and extra-pair paternity success increased...

Latitudinal cline of larval growth rate and its proximate mechanisms in a rhinoceros beetle

Wataru Kojima, Tatsunori Nakakura, Ayumi Fukuda, Chung-Ping Lin, Masahiro Harada, Yuki Hashimoto, Aika Kawachi, Shiho Suhama & Ryo Yamamoto
1. Juvenile growth rate is a key life-history trait with a major effect on various fitness components. Duration of the growing season changes with latitude, often resulting in latitudinal variations in growth rate. While many studies have shown a latitudinal cline of growth rate, most have used linear measurements of growth rate without considering the nonlinear nature of growth trajectories. Furthermore, elucidation of the proximate mechanisms causing increased growth rates would provide a fundamental understanding...

Herbivores reduce seedling recruitment in alpine plant communities

Øystein H. Opedal, Kristin Nystuen, Dagmar Hagen, Håkon Holien, Mia Sørensen, Simone Lang, Sigrid Lindmo, G. RIchard Strimbeck & Bente Graae
Through changes in climate and other environmental factors, alpine tundra ecosystems are subject to increased cover of erect shrubs, reduced predictability of rodent dynamics, and changes in wild and domesticated herbivore densities. To predict the dynamics of these ecosystems, we need to understand how these simultaneous changes affect alpine vegetation. In the long term, vegetation dynamics may depend critically on seedling recruitment. To study drivers of alpine plant seedling recruitment, we set up a field...

Data from: Influences of environmental and spatial factors on genetic and epigenetic variations in Rhododendron oldhamii (Ericaceae)

Chun-Lin Huang, Jui-Hung Chen, Ming-Hsuan Tsang, Jeng-Der Chung, Chung-Te Chang & Shih-Ying Hwang
Test of the relationship of genetic and particularly epigenetic variation with geographic isolation and environment is important to reveal potential environmental drivers for selection. Rhododendron oldhamii is widespread but inhabits fragmented subtropical forest landscapes and populations across its range may exhibit different levels of genetic and epigenetic structuring correlated to their environmental conditions. Here, we investigated the genetic and epigenetic variations and their ecological correlates in R. oldhamii. Genetic and epigenetic variations were surveyed using...
