The unique aquatic Pontocaspian (PC) biota of the Black Sea Basin (BSB) is in decline. The lack of detailed knowledge on the status and trends of species, populations and communities hampers a thorough risk assessment and precludes effective conservation. This paper reviews PC biodiversity trends in the BSB ( Bulgaria, Romania, Moldova, Ukraine and Russia) using endemic molluscs as a model group. We aim to assess changes in PC habitats, community structure and species distribution...

WiBB: An integrated method for quantifying the relative importance of predictive variables

Qin Li & Xiaojun Kou
This dataset contains simulated datasets, empirical data, and R scripts described in the paper: “Li, Q. and Kou, X. (2021) WiBB: An integrated method for quantifying the relative importance of predictive variables. Ecography (DOI: 10.1111/ecog.05651)”. A fundamental goal of scientific research is to identify the underlying variables that govern crucial processes of a system. Here we proposed a new index, WiBB, which integrates the merits of several existing methods: a model-weighting method from information theory...

The contribution of environmental and dispersal filters on beta diversity patterns in Amazonian tree communities

Juan Ernesto Guevara Andino, Nigel C.A. Pitman, Hans Ter Steege, Manuel Peralvo, Carlos Cerón & Paul V.A. Fine
Environmental filters (e.g. climate, geomorphology and soils) and dispersal filters are key determinants of species distributions of Amazonian tree communities. However, a comprehensive analysis of the role of environmental and dispersal filters is needed to understand the ecological and evolutionary processes that drive phylogenetic and taxonomic turnover of Amazonian tree communities. We compare measures of taxonomic and phylogenetic beta diversity in 40 one-hectare plots to test the relative importance of climate, soils, geology, geomorphology, pure...

Fossil-informed models reveal a Boreotropical origin and divergent evolutionary trajectories in the walnut family (Juglandaceae)

Qiuyue Zhang, Richard Ree, Nicolas Salamin, Yaowu Xing & Daniele Silvestro
Temperate woody plants in the Northern Hemisphere have long been known to exhibit high species richness in East Asia and North America and significantly lower diversity in Europe, but the causes of this pattern remain debated. Here, we quantify the roles of dispersal, niche evolution, and extinction in shaping the geographic diversity of the temperate woody plant family Juglandaceae (walnuts and their relatives). Integrating evidence from molecular, morphological, fossil, and (paleo)environmental data, we find strong...

Plant DNA metabarcoding record from a sediment core from Lake Naleng, southeastern Tibetan Plateau

Sisi Liu, Stefan Kruse, Dirk Scherler, Richard H. Ree, Heike H. Zimmermann, Kathleen R. Stoof-Leichsenring, Laura S. Epp, Steffen Mischke & Ulrike Herzschuh
Here, we provide the raw plant DNA metabarcoding data archived in Lake Naleng sediment core spanning the late-glacial to the present (17,700 to 0 cal yr BP). Lake Naleng (31.10° N, 99.7°5 E, 4200 above sea level) is situated in a glacially-formed basin on the southeastern Tibetan Plateau. It is an alpine freshwater lake with a maximum water depth of 36.7 m, an open surface area of 1.7 km2, a specific conductivity of 0.045 mS/cm,...

A target enrichment probe set for resolving the flagellate land plant tree of life

Ickert-Bond, Paulo H. Labiak, Juan Larraín, Marcus Lehnert, Lily R. Lewis, Nathalie S. Nagalingum, Nikisha Patel, Stefan A. Rensing, Weston Testo, Alejandra Vasco, Juan Carlos Villarreal, Evelyn Webb Williams, J. Gordon Burleigh, Sahut Chantanaorrapint, Leandro G. Neves … & Stefanie M. Ickert‐Bond
Premise of the Study: New sequencing technologies enable the possibility of generating large-scale molecular datasets for constructing the plant tree of life. We describe a new probe set for target enrichment sequencing to generate nuclear sequence data to build phylogenetic trees with any flagellate land plants, including hornworts, liverworts, mosses, lycophytes, ferns, and all gymnosperms. Methods and Results: We leveraged existing transcriptome and genome sequence data to design a set of 56,989 probes for target...

Sizes and environmental variables to peccaries

Carla D. Hendges, Bruce D. Patterson & Nilton C. Cáceres
Aim: Bergmann's rule is an ecogeographical rule that describes a negative relationship between body size and temperature. Here, we used a multivariate measure of skull size (centroid size) as a proxy for body size to test the influence of temperature, precipitation, elevation, human influence and competition on size in Dicotyles tajacu and Tayassu pecari. Location: American tropics and sub-tropics. Taxon: Tayassuidae. Methods: Using geometric morphometric methods, we measured 426 adult skulls of both peccary species...

Data from: Morphology and distribution of scales, dermal ossifications, and other non-feather integumentary structures in non-avialan theropod dinosaurs

Christophe Hendrickx, Phil R. Bell, Michael Pittman, Andrew R. C. Milner, Elena Cuesta, Jingmai O'Connor, Mark Loewen, Philip J. Currie, Octávio Mateus, Thomas G. Kaye & Rafael Delcourt
Modern birds are typified by the presence of feathers, complex evolutionary innovations that were already widespread in the group of theropod dinosaurs (Maniraptoriformes) that include crown Aves. Squamous or scaly reptilian-like skin is, however, considered the plesiomorphic condition for theropods and dinosaurs more broadly. Here, we review the morphology and distribution of non-feathered integumentary structures in non-avialan theropods covering squamous skin and naked skin as well as dermal ossifications. The integumentary record of non-averostran theropods...
