The emergence of venom is an evolutionary innovation that favored the diversification and survival of snakes. The composition of snake venoms is known in detail from venom gland proteomic data. However, there is still a gap of knowledge about the forces that lead to the expression of different toxins in different proportions in the venom cocktail across space and time. LOCATION World. TIME PERIOD Modern. MAJOR TAXA STUDIED Elapidae and Viperidae. We integrated proteomic data...
Area and Timing data and R script for: 3D scanning as a tool to measure growth rates of live coral microfragments used for coral reef restorationHanna Koch, Bailey Wallace, Allyson DeMerlis, Abigail Clark & Robert Nowicki
Rapid and widespread declines in coral health and abundance have driven increased investments in coral reef restoration interventions to jumpstart population recovery. Microfragmentation, an asexual propagation technique, is used to produce large numbers of corals for research and restoration. As part of resilience-based restoration, coral microfragments of different genotypes and species are exposed to various stressors to identify candidates for propagation. Growth rate is one of several important fitness-related traits commonly used in candidate selection,...
Interindividual plasticity in metabolic and thermal tolerance traits from populations subjected to recent anthropogenic heatingMelissa Drown, Amanda DeLiberto, Moritz Ehrlich, Douglas Crawford & Marjorie Oleksiak
To better understand temperature’s role in the interaction between local evolutionary adaptation and physiological plasticity, we investigated acclimation effects on metabolic performance and thermal tolerance among natural Fundulus heteroclitus populations from different thermal environments. F. heteroclitus populations experience large daily and seasonal temperature variations, as well as local mean temperature differences across their large geographic cline. In this study, we focus on three populations: one locally heated (32°C) by thermal effluence (TE) from the Oyster...
Comparison of adult census size and effective population size support the need for continued protection of two Solomon Island endemicsSarah A. Cowles, Brian C. Weeks, Lindsey Perrin, Nancy Chen & J. Albert C. Uy
Because a population’s ability to respond to rapid change is dictated by standing genetic variation, we can better predict a population’s long-term viability by estimating and then comparing adult census size (N) and effective population size (Ne). However, most studies only measure N or Ne, which can be misleading. Using a combination of field and genomic sequence data, we here estimate and compare N and Ne in two range-restricted endemics of the Solomon Islands. Two...
This dataset (Andean_AGB.xlsx) has the data employed in the paper entitled Old-growth Andean forests as globally important carbon sinks and future carbon refuges. The data was compiled as the results of the work of several research teams spread out across the Andean region. The information available here has data about aboveground carbon stocks and dynamics and the main explanatory variables, such as climate and symbiotic root associations.
Synthesis and Binding Properties of Monohydroxycucurbituril: A Key Derivative for the Functionalization of Cucurbituril HostsNan Dong, Jing He, Tao Li, Andrea Peralta, Mehdi Rashvand Avei, Mingfang Ma & Angel E. Kaifer
We present a simple, direct method to prepare monohydroxylated cucurbituril (CB7-OH) through the direct oxidation of its precursor host, cucurbituril (CB7). Although the conversion takes place in low yield (14%), the isolation of CB7-OH from the reaction mixture is straightforward, and the unreacted CB7 can be easily recovered. ITC measurements with several selected guests confirmed that CB7-OH binds all of them in aqueous solution with similar, albeit slightly lower, binding affinities than those observed with...
Complexation of Ferrocene Derivatives by the Cucurbituril Host: A Comparative Study of the Cucurbituril and Cyclodextrin Host FamiliesWoo Sung Jeon, Kwangyul Moon, Sang Hyun Park, Hyungpil Chun, Young Ho Ko, Jin Yong Lee, Eun Sung Lee, S. Samal, N. Selvapalam, Mikhail V. Rekharsky, Vladimir Sindelar, David Sobransingh, Yoshihisa Inoue, Angel E. Kaifer & Kimoon Kim
The formation of inclusion complexes between cucurbituril (CB) and ferrocene and its derivatives has been investigated. The X-ray crystal structure of the 1:1 inclusion complex between ferrocene and CB revealed that the guest molecule resides in the host cavity with two different orientations. Inclusion of a set of five water-soluble ferrocene derivatives in CB was investigated by 1H NMR spectroscopy and calorimetric and voltammetric techniques. Our data indicate that all neutral and cationic guests form...
The dicationic guest 2,7-dimethyldiazapyrenium is bound inside the host cucurbituril, forming a very stable inclusion complex in which the host undergoes structural distortions to accommodate the guest.
Unusual Electrochemical Properties of the Inclusion Complexes of Ferrocenium and Cobaltocenium with CucurbiturilAngel E. Kaifer & Winston Ong
Ferrocenium and cobaltocenium form highly stable 1:1 inclusion complexes with the host cucurbituril. From electronic absorption spectroscopic data the association equilibrium constants for both complexes were found to be larger than 106 L/mol. The electrochemical reduction of either guest leads to a modest loss in binding affinity.
2019 Survey of Florida Residents to Evaluate Public Comprehension of the “Cone of Uncertainty” GraphicScotney Evans, Kenneth Broad, Alberto Cairo, Sharanya Majumdar, Brian McNoldy, Barbara Millet & Leigh Rauk
This data set contains results from an online survey targeting a sample of 2,847 Florida residents in 2019. Unlike previous public surveys that focused more on evacuation decisions, forecast usage, and perception of hurricane risk, our approach specifically pays attention to the details of design elements of the forecast graphics with the long-term goal of minimizing misinterpretation of future graphics. The survey comprised 55 mostly multiple-choice and True/False questions, including demographic information and a series...
First Atlantic satellite tracks of lost years green turtles support the importance of the Sargasso Sea as a sea turtle nurseryKatherine Mansfield, Jeanette Wyneken & Jiangang Luo
In-water behaviour and long-term movements of oceanic-stage juvenile sea turtles are not well described or quantified. This is due to technological or logistical limitations of tracking small, fast-growing animals across long distances and time-periods within marine habitats. Here we present the first long-term offshore tracks of oceanic green turtles (Chelonia mydas) in western North Atlantic waters. Using a tag attachment technique developed specifically for young (<1 year old) green turtles, we satellite tracked 21 oceanic-stage...
Abstract from the article associated with the dataset: George, Mullinix, et al PeerJ 2021. Reef-building corals are ecosystem engineers that compete with other benthic or- ganisms for space and resources. Corals harvest energy through their surface by photosynthesis and heterotrophic feeding, and they divert part of this energy to defend their outer colony perimeter against competitors. Here, we hypothesized that corals with a larger space-filling surface and smaller perimeters increase energy gain while reducing the...
The carbon isotope fractionation in algal organic matter (Ep), including the long-chain alkenones produced by the coccolithophorid family Noelaerhabdaceae, is used to reconstruct past atmospheric CO2 levels. The conventional proxy linearly relates Ep to changes in cellular carbon demand relative to diffusive CO2 supply, with larger Ep values occurring at lower carbon demand relative to supply (i.e. abundant CO2). However, the response of Gephyrocapsa oceanica, one of the dominant alkenone producers of the last few...
A supramolecular complex between benzoates and a bambusuril crystallizes out immediately after mixing in chloroform but only in the presence of residual water molecules. In this complex each of the two portals of the macrocycle is occupied by one benzoate. Carboxylate groups are connected through hydrogen bo
The formation of inclusion complexes between the cucurbituril host and a cationic guest containing ferrocenylmethyl and adamantyl residues connected to an ammonium nitrogen initially leads to an ∼1:1 mixture of two isomeric microscopic complexes, which evolves as a function of time toward the thermodynamically stable mixture, dominated by the adamantyl-included complex.
Abstract Methods for the preparation of anion-free bambusuril (BU6) are presented. They are based on the oxidation of iodide anion, which is bound inside the macrocycle, utilizing dark oxidation...
