Data from: A millennium of climatic and floristic dynamics in the Eastern Cordillera of the Colombian Andes

Alex Correa, Jaime Escobar, Broxton Bird, Dayenari Caballero-Rodríguez, Byron Steinman, Paula A. Rodríguez-Zorro & Jason Curtis
The transition from the Medieval Climate Anomaly (MCA, 950-1250 CE) to the Little Ice Age (LIA, 1350 to 1800 CE) is the largest pre-industrial climate shift within the last two millennia, offering an opportunity to study how vegetation responds to rapid climate change. We analyzed a sedimentary record from the Colombian Andes to reconstruct regional vegetation dynamics during this time interval, identify the modern environmental distribution of taxa present in the fossil record, and provide...

Data from: Sea turtle epibiosis: Global patterns and knowledge gaps

Joseph B. Pfaller & Nathan J. Robinson
This database serves to summarize over 100 years of sea turtle epibiont research. We conducted a two-tiered literature search to compile all records of sea turtle-epibiont interactions along with their associated metadata. A structured search was conducted in Web of Science, Google Scholar, and Sea Turtle Online Bibliography (Archie Carr Center for Sea Turtle Research, University of Florida), then an unstructured literature search was conducted by reviewing the reference lists of all relevant publications and...

Allison C. Candelmo, Aylin Ulman, Fadilah Z. Ali, Stephen R. Gittings, Summer R. Huber, Lauryn E. Magno, Kaylin R. Clements, Burak Ali Çiçek, Jennifer K. Chapman, Fabian C. Kyne, Michel Bariche, Kimani Kitson-Walters, Francesco Tiralongo, Demetris Kletou, Taner Yildiz, Nir Stern, Sara A.A. Al Mabruk, Mohammed Adel, Nejmeddine Bradai, Shevy B.S. Rothman, Vasileios Minasidis, Stephanie J. Green, Jennifer N. Solomon, Holden E. Harris, Philip E. Karp … & James V Hart
The invasion of lionfish (Pterois volitans and P. miles) in the Western Atlantic is perhaps the best studied marine fish invasion to date; meanwhile another lionfish invasion is rapidly evolving in the Mediterranean. We reviewed lionfish management policies from several decades in the Western Atlantic to suggest policy recommendations for the Mediterranean. These strategic recommendations are synthesized in our corresponding manuscript titled: “Lessons from the Western Atlantic lionfish invasion can inform policy and management strategies...

Data and code from: Invasive grass indirectly alters seasonal patterns in seed predation

Jesse Borden, Kelly M. San Antonio, Giovanna Tomat-Kelly, Taylor Clark & S. Luke Flory
Invasive species threaten ecosystems globally, but their impacts can be cryptic when they occur indirectly. Invader phenology can also differ from that of native species, potentially causing seasonality in invader impacts. Yet, it is unclear if invader phenology can drive seasonal patterns in indirect effects. We used a field experiment to test if an invasive grass (Imperata cylindrica) caused seasonal indirect effects by altering rodent foraging and seed predation patterns through time. Using seeds from...

Data from: Implementation of a pediatric telemedicine and medication delivery service in a resource-limited setting: A pilot study for clinical safety and feasibility

Molly B. Klarman, Katelyn E. Flaherty, Xiaofei Chi, Youseline Cajsuma, Anne Carine Capois, Michel Daryl Vladimir Dofiné, Lerby Exantus, Jason Friesen, Valery M Beau De Rochars, Chantale Baril, Matthew J. Gurka, Torben K. Becker & Eric J. Nelson
Objective: Determine the clinical safety and feasibility of implementing a telemedicine and medication delivery service (TMDS) to address gaps in nighttime healthcare access for children in low-resource settings. Results: A total of 391 cases were enrolled from September 9th, 2019 to January 19th, 2021; 89% (347) received a household visit. Most cases were triaged as mild or moderate (92%; 361). Among the severe cases, 83% (20) sought subsequent referred care. The most common complaint was...

Data from: Blood-red colour as a prey-choice cue for mosquito specialist predators

Lisa Taylor, Fiona Cross & Robert Jackson
Specialist predators are innately and distinctively proficient at targeting specific prey types. This is enabled by behavioural, perceptual, and cognitive mechanisms that can only be understood using carefully-designed experiments. Evarcha culicivora is an East African jumping spider that feeds on vertebrate blood acquired indirectly by actively targeting blood-carrying female mosquitoes as preferred prey. Here we asked whether these spiders use the colour red to locate this prey. In Objective 1, we used spectrophotometry to document...

A specialist bee and its host plants experience phenological shifts at different rates in response to climate change

Sarah Weaver & Rachel Mallinger
Changes in climate can alter the phenology of organisms, potentially decoupling partners within mutualisms. Previous studies have shown that plant and pollinator phenologies are shifting over time, but these shifts have primarily been documented for generalists and within small geographic regions, and the specific climatic cues regulating these shifts are not well-understood. We examined phenological shifts in a specialist pollinator and its host plant species over a 117-year study period using a digitized dataset of...

From nature reserve to mosaic management: improving matrix survival, not permeability, benefits regional populations under habitat loss and fragmentation

Yuichi Yamaura, Robert Fletcher, Steven Lade, Motoki Higa & David Lindenmayer
Although matrix improvement in fragmented landscapes is a promising conservation measure, matrix permeability (willingness of an organism to enter the matrix) and movement survival in the matrix are usually aggregated. Consequently, it is unknown which matrix property needs to be improved. It also remains unclear whether matrix upgrading from dispersal passage to providing reproduction opportunities has large conservation benefits and whether there are interactive effects between habitat and matrix management. We examined matrix effects on...

PRMI: A dataset of minirhizotron images for diverse plant root study

Weihuang Xu, Guohao Yu, Yiming Cui, Romain Gloaguen, Alina Zare, Jason Bonnette, Joel Reyes-Cabrera, Ashish Rajurkar, Diane Rowland, Roser Matamala, Julie D. Jastrow, Thomas E. Juenger & Felix B. Fritschi
Understanding a plant's root system architecture (RSA) is crucial for a variety of plant science problem domains including sustainability and climate adaptation. Minirhizotron (MR) technology is a widely-used approach for phenotyping RSA non-destructively by capturing root imagery over time. Precisely segmenting roots from the soil in MR imagery is a critical step in studying RSA features. In this paper, we introduce a large-scale dataset of plant root images captured by MR technology. In total, there...

Data from: Evaluating the use of lidar to discern snag characteristics important for wildlife

Jessica M. Stitt, Andrew T. Hudak, Carlos A. Silva, Lee A. Vierling & Kerri T. Vierling
Standing dead trees (known as snags) are historically difficult to map and model using airborne laser scanning (ALS), or lidar. Specific snag characteristics are important for wildlife; for instance, a larger snag with a broken top can serve as a nesting platform for raptors. The objective of this study was to evaluate whether characteristics such as top intactness could be inferred from discrete-return ALS data. We collected structural information for 198 snags in closed-canopy conifer...

Human-mediated trophic mismatch between fire, plants, and herbivores

Marcus Lashley, Michael Chitwood, Jacob Dykes, Christopher DePerno & Christopher Moorman
Trophic mismatches are commonly reported across a wide array of taxa and can have important implications for species participating in the interaction. However, to date, examples of trophic mismatch have centrally focused on those induced by shifts in climate. Here we report on the potential for humans to induce trophic mismatch by shifting the phenology of fire. Globally, anthropogenic fire ignitions are phenologically mismatched to that of historic lightning ignitions but the effects of this...

Two new species of Miconia s.lat. (Melastomataceae) from Espírito Santo, Brazil

Renato Goldenberg, Lucas F. Bacci, Thuane Bochorny & Marcelo Reginato
We here describe two new species endemic to the state of Espírito Santo, Brazil, that belong to different clades within Miconia s.lat. Miconia quartzicola is presumably part of the Leandra s.str. clade, as indicated by its terminal inflorescences and petals with an acute apex. It has been collected only once in the municipality of Vargem Alta in disturbed vegetation on loose quartzitic substrate (‘morros de sal’). Miconia spiritusanctensis belongs to Miconia sect. Cremanium, as indicated...

Data from: Evolution and biogeography of Memecylon

Prabha Amarasinghe, Sneha Joshi, Navendu Page, Lahiru S. Wijedasa, Mary Merello, Hashendra Kathriarachchi, Robert Douglas Stone, Walter Judd, Ullasa Kodandaramaiah & Nico Cellinese
Premise The woody plant group Memecylon (Melastomataceae) is a large clade occupying diverse forest habitats in the Old World tropics and exhibiting high regional endemism. Its phylogenetic relationships have been previously studied using ribosomal DNA with extensive sampling from Africa and Madagascar. However, divergence times, biogeography, and character evolution of Memecylon remain uninvestigated. We present a phylogenomic analysis of Memecylon to provide a broad evolutionary perspective of this clade. Methods One hundred supercontigs of 67...

Species-level tree crown maps improve predictions of tree recruit abundance in a tropical landscape

Cristina Barber, Sarah Graves, Jefferson Hall, Pieter Zuidema, Jodi Brandt, Stephanie Bohlman, Gregory Asner, Mario Bailón & T. Trevor Caughlin
Predicting forest recovery at landscape scales will aid forest restoration efforts. The first step in successful forest recovery is tree recruitment. Forecasts of tree recruit abundance, derived from the landscape-scale distribution of seed sources (i.e. adult trees), could assist efforts to identify sites with high potential for natural regeneration. However, previous work has revealed wide variation in the effect of seed sources on seedling abundance, from positive to no effect. We quantified the relationship between...

Data from: A diversification relay race from Caribbean-Mesoamerica to the Andes: historical biogeography of Xylophanes hawkmoths

Xuankun Li, Chris Hamilton, Ryan Laurent, Liliana Ballesteros-Mejia, Amanda Markee, Rodolphe Rougerie, Ian Kitching & Akito Kawahara
The regions of the Andes and Caribbean-Mesoamerica are both hypothesized to be the cradle for many Neotropical lineages, but few studies have fully investigated the dynamics and interactions between Neotropical bioregions. The NewWorld hawkmoth genus Xylophanes is the most taxonomically diverse genus in the Sphingidae, with the highest endemism and richness in the Andes and Caribbean-Mesoamerica. We integrated phylogenomic and DNA barcode data and generated the first time-calibrated tree for this genus, covering 93.8% of...

Anti-bat ultrasound production in moths is globally and phylogenetically widespread

Jesse Barber, David Plotkin, Juliette Rubin, Nicholas Homziak, Brian Leavell, Peter Houlihan, Krystie Miner, Jesse Breinholt, Brandt Quirk-Royal, Pablo Sebastián Padrón, Matías Nuñez & Akito Kawahara
Warning signals are well known in the visual system, but rare in other modalities. Some moths produce ultrasonic sounds to warn bats of noxious taste or to mimic unpalatable models. Here we report results from a long-term study across the globe, assaying moth response to playback of bat echolocation. We tested 252 genera, spanning most families of large-bodied moths, and document anti-bat ultrasound production in 52 genera, with eight new subfamily origins described. Based on...

Mutation, selection, and the prevalence of the C. elegans heat-sensitive mortal germline phenotype

Sayran Saber, Michael Snyder, Moein Rajaei & Charles Baer
C. elegans strains with the heat-sensitive mortal germline (Mrt) phenotype become progressively sterile over the course of a few tens of generations when maintained at temperatures near the upper range of C. elegans' tolerance. Mrt is transgenerationally-heritable, and proximately under epigenetic control. Previous studies have suggested that Mrt presents a relatively large mutational target, and that Mrt is not uncommon in natural populations of C. elegans. The Mrt phenotype is not monolithic. Some strains exhibit...

Darwin’s Hawkmoth (Xanthopan praedicta) responds to bat ultrasound at sonar-jamming rates: Acoustic data set

Juliette Rubin
This paper reveals that Xanthopan praedicta (Lepidoptera: Sphingidae) is part of the bat-moth coevolutionary dynamic. I played recordings of bat echolocation to live X. praedicta and found that males respond with such dense ultrasound they can likely jam bat sonar. Female X. praedicta and two other sphingid species do not produce ultrasonic responses.

Experimental disruption of social structure reveals totipotency in the orchid bee, Euglossa dilemma

Nicholas Saleh
Eusociality has evolved multiple times across the insect phylogeny. Social insects with greater levels of social complexity tend to exhibit specialized castes with low levels of individual phenotypic plasticity. In contrast, species with simple social groups may consist of totipotent individuals that transition among behavioral and reproductive states. However, recent work has shown that in simple social groups, there can still be constraint on individual plasticity, caused by differences in maternal nourishment or social interaction....

Transcriptional networks underlying a primary ovarian insufficiency disorder in alligators naturally exposed to EDCs: Transformed read counts and supplementary materials

Matthew Hale, Therese Koal, Tuan Hai Pham, John Bowden & Ben Parrott
Interactions between the endocrine system and environmental contaminants are responsible for impairing reproductive development and function. Despite the taxonomic diversity of affected species and attendant complexity inherent to natural systems, the underlying signaling pathways and cellular consequences are mostly studied in lab models. To resolve the genetic and endocrine pathways that mediate affected ovarian function in organisms exposed to endocrine disrupting contaminants in their natural environments, we assessed broad-scale transcriptional and steroidogenic responses to exogenous...

Data from: Global plant ecology of tropical ultramafic ecosystems

Catherine Hulshof, Claudia Garnica-Díaz, Rosalina Berazaín Iturralde, Betsaida Cabrera, Erick Calderón-Morales, Fermín L. Felipe, Ricardo García, José Luis Gómez Hechavarría, Aretha Franklin Guimarães, Ernesto Medina, Adrian L.D. Paul, Nishanta Rajakaruna, Carla Restrepo, Stefan Siebert, Eduardo Van Den Berg, Antony Van Der Ent & Grisel Velasquez
This is a compiled geospatial dataset in ESRI polygon shapefile format of ultramafic soils of the neotropics showing the location of ultramafic soils in Guatemala, Cuba, Dominican Republic, Puerto Rico, Costa Rica, Colombia, Argentina, Chile, Venezuela, Ecuador, Brazil, Suriname, French Guiana, and Bolivia. The data are derived from seven geospatial datasets. Original datasets were subset to include only ultramafic areas, datasets were assigned a common projection (WGS84), attribute tables were reconciled to a common set...

Standardized nuclear markers improve and homogenize species delimitation in Metazoa

Lars Dietz, Jonas Eberle, Christoph Mayer, Sandra Kukowka, Claudia Bohacz, Hannes Baur, Marianne Espeland, Bernhard A. Huber, Carl Hutter, Ximo Mengual, Ralph S. Peters, Miguel Vences, Thomas Wesener, Keith Willmott, Bernhard Misof, Oliver Niehuis & Dirk Ahrens
Species are the fundamental units of life and their recognition is essential for science and society. DNA barcoding, the use of a single and often mitochondrial gene, has been increasingly employed as a universal approach for the identification of animal species. However, this approach faces several challenges. Here, we demonstrate with empiricalgenomic data from nine metazoan animal lineages including arthropods and 28 vertebrates that multiple nuclear-encoded markers, so called universal single-copy orthologs (USCOs) performs much...

Regeneration data of bryophyte fragments extracted from feces of Chloephaga picta and Attagis malouinus in Navarino Island, sub-Antarctic Chile

Xenabeth Lazaro, Roy Mackenzie & Jaime Jimenez
Birds are known to act as potential vectors for the exogenous dispersal of bryophyte diaspores. Given the totipotency of vegetative tissue of many bryophytes, birds could also contribute to endozoochorous bryophyte dispersal. Research has shown that fecal samples of the upland goose (Chloephaga picta) and white-bellied seedsnipe (Attagis malouinus) contain bryophyte fragments. Although few fragments from bird feces have been known to regenerate, the evidence for the viability of diaspores following passage through the bird...

On the genetic architecture of rapidly adapting and convergent life history traits in guppies

James Whiting, Josephine Paris, Paul Parsons, Sophie Matthews, Yuridia Reynoso, Kimberly Hughes, David Reznick & Bonnie Fraser
The genetic basis of traits shapes and constrains how adaptation proceeds in nature; rapid adaptation can be facilitated by polygenic traits, which subsequently provide multiple, redundant, genetic routes to adaptive phenotypes, reducing re-use of the same genes (genetic convergence). Guppy life history traits evolve rapidly and convergently among natural high- (HP) and low-predation (LP) environments in northern Trinidad. This system has been studied extensively at the phenotypic level, but little is known about the underlying...
