Data from: Interglacial microrefugia and diversification of a cactus species complex: phylogeography and palaeodistributional reconstructions for Pilosocereus aurisetus and allies

Isabel A. S. Bonatelli, Manolo F. Perez, A. Townsend Peterson, Nigel P. Taylor, Daniela C. Zappi, Marlon C. Machado, Ingrid Koch, Adriana H. C. Pires & Evandro M. Moraes
The role of Pleistocene climate changes in promoting evolutionary diversification in global biota is well documented, but the great majority of data regarding this subject come from North America and Europe, which were greatly affected by glaciation. The effects of Pleistocene changes on cold- and/or dry-adapted species in tropical areas where glaciers were not present remain sparsely investigated. Many such species are restricted to small areas surrounded by unfavourable habitats, which may represent potential interglacial...

Data from: Roads to isolation: similar genomic history patterns in two species of freshwater crabs with contrasting environmental tolerances and range sizes

Ywee Chieh Tay, Daniel Jia Jun Ng, Jun Bin Loo, Danwei Huang, Yixiong Cai, Darren Chong Jinn Yeo & Rudolf Meier
Freshwater species often show high levels of endemism and risk of extinction owing to their limited dispersal abilities. This is exemplified by the stenotopic freshwater crab, Johora singaporensis which is one of the world's 100 most threatened species, and currently inhabits less than 0.01 km2 of five low order hill streams within the highly urbanized island city‐state of Singapore. We compared populations of J. singaporensis with that of the non‐threatened, widespread, abundant, and eurytopic freshwater...

Data from: Beyond the Coral Triangle: high genetic diversity and near panmixia in Singapore's populations of the broadcast spawning sea star Protoreaster nodosus

Ywee Chieh Tay, Michelle W.P. Chng, W. W. Genevieve Sew, Frank E. Rheindt, Karenne P.P. Tun, Rudolf Meier & M. W. P. Chng
The Coral Triangle is widely considered the most important centre of marine biodiversity in Asia while areas on its periphery such as the South China Sea, have received much less interest. Here, we demonstrate that a small population of the knobbly sea star Protoreaster nodosus in Singapore has similarly high levels of genetic diversity as comparable Indonesian populations from the Coral Triangle. The high genetic diversity of this population is remarkable because it is maintained...

Data from: Convergent morphology in Alpinieae (Zingiberaceae): recircumscribing Amomum as a monophyletic genus

Hugo De Boer, Mark Newman, Axel Dalberg Poulsen, A. Jane Droop, Tomas Fer, Le Thi Thu Hien, Kristyna Hlavata, Vichith Lamxay, James E. Richardson, Karin Steffen & Jana Leong-Škorničková
The tropical ginger genus Amomum (Zingiberaceae) has always posed challenges for classification based on morphological characters. Previous molecular phylogenetic studies showed Amomum to be paraphyletic but limited sampling and absence of the data of the type Amomum subulatum made it impossible to resolve the paraphyly and make nomenclatural changes. Here, Amomum is further investigated in a multi-marker phylogenetic framework using matK and nrITS including multiple accessions of the type, the genus Elettaria and additional accessions...

Data from: Coral settlement on a highly disturbed equatorial reef system

Andrew G. Bauman, James R. Guest, Glenn Dunshea, Jeffery Low, Peter A. Todd & Peter D. Steinberg
Processes occurring early in the life stages of corals can greatly influence the demography of coral populations, and successful settlement of coral larvae that leads to recruitment is a critical life history stage for coral reef ecosystems. Although corals in Singapore persist in one the world’s most anthropogenically impacted reef systems, our understanding of the role of coral settlement in the persistence of coral communities in Singapore remains limited. Spatial and temporal patterns of coral...

Data from: The influence of the COVID-19 pandemic on the demand for different shades of green

Kathleen Yap, Malcolm Soh, Angelia Sia, Wei Jun Chin, Sophianne Araib, Wei Ping Ang, Puay Yok Tan & Kenneth Er
COVID-19 has heightened the dependence of urban dwellers on cultural ecosystem services provided by urban green spaces (UGS), specifically in regard to the provision of recreational opportunities, and psychological and physical health benefits arising from their use. As different types and levels of cultural ecosystem services are provided by different types of UGS, people may seek out different UGS to satisfy personal needs over various phases of COVID-19 mobility restrictions imposed by cities. We report...

The different fates of two Asian horseshoe crab species with different dispersal abilities

Qian Tang, Prashant Shingate, Yusli Wardiatno, Akbar John, Boon Hui Tay, Ywee Chieh Tay, Laura-Marie Yap, Jasmin Lim, Hor Yee Tong, Karenne Tun, Byrappa Venkatesh & Frank E. Rheindt
Impending anthropogenic climate change will severely impact coastal organisms at unprecedented speed. Knowledge on organisms’ evolutionary responses to past sea level fluctuations and estimation of their evolutionary potential is therefore indispensable in efforts to mitigate the effects of future climate change. We sampled tens of thousands of genomic markers of ~300 individuals in two of the four extant horseshoe crab species across the complex archipelagic Singapore Straits. Carcinoscorpius rotundicauda Latreille, a less mobile mangrove species,...

Data from: Leaf litter decomposition in tropical freshwater swamp forests is slower in swamp than non-swamp conditions

Weng Ngai Lam, Jun Jie Lian, Pin Jia Chan, Ying Ying Ting, Rie Chong, Nur Estya Rahman, Lorraine Tan, Qian Yi Ho, Sorain Ramchunder, Kelvin Peh, Yixiong Cai & Kwek Yan Chong
Decomposition is a key ecosystem function, and the rate of decomposition in forests affects their carbon storage potentials. Processes and factors determining leaf litter decomposition rates in dry-land and temperate forests are well understood, but these are generally poorly studied in tropical wetland forests, especially freshwater swamp forests (FSF). The home-field advantage (HFA) hypothesis predicts that soil microbes specialize in decomposing leaf litter produced by the tree species in their immediate vicinity. However, empirical support...
