ISIMIP3b N-deposition input data

Jia Yang & Hanqin Tian
The Inter-Sectoral Impact Model Intercomparison Project (ISIMIP) provides a framework for the collation of a consistent set of climate impact data across sectors and scales. It also provides a unique opportunity for considering interactions between climate change impacts across sectors through consistent scenarios.
The ISIMIP3b part of the third simulation round is dedicated to a quantification of climate-related risks at different levels of global warming and socio-economic change. ISIMIP3b group I simulations are based on historical...

Implications of overfishing of frugivorous fishes for cryptic function loss in a Neotropical floodplain

Joisiane Araujo, Sandra Bibiana Correa, Jerry Penha, Jill Anderson & Anna Traveset
Many frugivorous animals act simultaneously as seed predators and dispersers, and shifts in the abundance and mean phenotype of the frugivore population can alter the prevalence of antagonistic vs mutualistic interactions with seeds. Here, we evaluated how a reduction in the abundance and species richness of large-bodied frugivorous fishes affects their interactions with plants in a Neotropical floodplain. Fisheries selectively harvest large frugivorous fishes, which are the most effective seed dispersers. Thus, functional extinctions of...

Contrasting patterns of phylogenetic diversity and alpine specialization across the alpine flora of the American mountain range system

Hector Fox Figueroa, Hannah E. Marx, Maria Beatriz De Souza Cortez, Charles J. Grady, Nicholas Engle-Wrye, Jim Beach, Aimee Stewart, Ryan A. Folk, Douglas E. Soltis, Pamela S. Soltis & Stephen A. Smith
Although mountainous habitats contribute substantially to global biodiversity, comparatively little is known about biogeographic patterns of distributions of alpine species across multiple mountain ranges. Here, we present a detailed analysis of the distributions and phylogenetic affinities of alpine seed plant lineages across North, Central, and South American mountain systems. Using a comprehensive dataset that characterized the elevational niches of American seed plants in a continuously valued way, we were able to quantitatively investigate how the...

The integrin-mediated adhesive complex in the ancestor of animals, fungi, and amoebae

Matthew Brown, Seungho Kang, Alexander K. Tice, Courtney W. Stairs, Robert E. Jones, Daniel J.G. Lahr & Matthew W. Brown
Integrins are transmembrane receptors that activate signal transduction pathways upon extracellular matrix binding. The integrin-mediated adhesive complex (IMAC) mediates various cell physiological processes. Although the IMAC was thought to be specific to animals, in the past ten years these complexes were discovered in other lineages of Obazoa, the group containing animals, fungi, and several microbial eukaryotes. Very recently, many genomes and transcriptomes from Amoebozoa (the eukaryotic supergroup sister to Obazoa), other obazoans, and orphan protist...

Large‐scale genome sampling reveals unique immunity and metabolic adaptations in bats

Diana Daniela Moreno Santillan, Tanya Lama, Yocelyn T Gutierrez Guerrero, Zixia Huang, Graham Hughes, Alexis Brown, Paul Donat, Huabin Zhao, Stephen Rossiter, Laurel Yohe, Joshua Potter, Emma Teeling, Sonja Vernes, Kalina Davies, Eugene Myers, Federico Hoffmann, Angelique Corthals, David Ray & Liliana Davalos
Comprising more than 1,400 species, bats possess adaptations unique among mammals including powered flight, unexpected longevity given small body size, and extraordinary immunity. Some of the molecular mechanisms underlying these unique adaptations includes DNA repair, metabolism and immunity. However, analyses have been limited to a few divergent lineages, reducing the scope of inferences on gene family evolution across the Order Chiroptera. We conducted an exhaustive comparative genomic study of 37 bat species encompassing a large...

Microsatellites data set: Correlated population genetic structure in a three-tiered host-parasite system: the potential for coevolution and adaptive divergence

Giuliano Colosimo
Three subspecies of Northern Bahamian Rock Iguanas, Cyclura cychlura, are currently recognized: C. c. cychlura,restricted to Andros Island, and C. c. figginsi and C. c. inornata, native to the Exuma Island chain. Populations on Andros are genetically distinct from Exuma Island populations, yet genetic divergence among populations in the Exumas is inconsistent with the two currently recognized subspecies from those islands. The potential consequences of this discrepancy might include the recognition of a single subspecies...

Quantifying niche similarity among new world seed plants--Species Distribution Models (SDMs) & associated metadata

Hector Figueroa, Hannah Marx, CJ Grady, Jim Beach, Ryan Folk, Douglas Soltis, Pamela Soltis, Aimee Stewart & Stephen Smith
Niche shift and conservatism are often framed as mutually exclusive. However, both processes could contribute to biodiversity patterns. We tested this expectation by quantifying the degree of climatic niche similarity among New World seed plants. To incorporate the biological reality that species experience varied abiotic conditions across their range, we assembled distribution models and used these to characterize temperature, precipitation, and elevation niches for species as continuously-valued distributions. We then quantified niche similarity (distributional overlap)...

ISIMIP3a N-deposition input data

Jia Yang & Hanqin Tian
The Inter-Sectoral Impact Model Intercomparison Project (ISIMIP) provides a framework for the collation of a consistent set of climate impact data across sectors and scales. It also provides a unique opportunity for considering interactions between climate change impacts across sectors through consistent scenarios.
The ISIMIP3a part of the third simulation round is dedicated to i) impact model evaluation and improvement and ii) detection and attribution of observed impacts according to the framework of IPCC AR5 Working...

Spatial conservation prioritization for the Amur tiger in Northeast China

Zexu Long, Jiayin Gu, Guangshun Jiang, Marcel Holyoak, Guiming Wang, Heng Bao, Peiqi Liu, Minghai Zhang & Jianzhang Ma
Amur tiger (Panthera tigris altaica) is critically endangered and also the subspecies of the tiger with the most restoration potential in China. It is challenging to protect large-ranging carnivores like tigers under increasing pressure of human development. To provide a more technically robust foundation for tiger habitat conservation prioritization, we conducted a comprehensively empirical analysis based on a broadly collected occurrence dataset of tigers and their prey. We modeled tiger distribution by running an ensemble...

Shark captures near west-central Florida by Coastal Marine Education and Research Academy

Lindsay Mullins
Identifying critical habitat for highly mobile species such as sharks is difficult, but essential for effective management and conservation. In regions where baseline data are lacking, non-traditional data sources have the potential to increase observational capacity for species distribution and habitat studies. In this study, a research and education organization conducted a five year (2013-2018) survey of shark populations in the coastal waters of west-central Florida, an area where a diverse shark assemblage has been...
