Rare species biodiversity, socio-demographics and local and landscape characteristics in Northern California community urban gardens

Theresa Ong, Brenda Lin, Azucena Lucatero, Hamutahl Cohen, Peter Bichier, Monika Egerer, Alana Danieu, Shalene Jha & Stacy Philpott
Cities are sometimes characterized as homogenous with species assemblages composed of abundant, generalist species having similar ecological functions. Under this assumption, rare species, or species observed infrequently, would have especially high conservation value in cities for their potential to increase functional diversity. Management to increase the number of rare species in cities could be an important conservation strategy in a rapidly urbanizing world. However, most studies of species rarity define rarity in relatively pristine environments...

Using GBIF to Demonstrate Colonial Legacies on Biodiversity Data

Ryan S. Mohammed, Melissa Kemp, Michelle J. LeFebvre, Alexis M. Mychajliw, Grace Turner, Kelly Fowler, Michael Pateman, Maria A. Nieves-Colón, Lanya Fanovich, Siobhan B. Cooke, Liliana M. Dávalos, Scott M. Fitzpatrick, Christina M. Giovas, Myles Stokowski & Ashley A. Wrean
Biologists recognize the Caribbean archipelago as a biodiversity hotspot and employ it for their research as a “natural laboratory”, but do not always appreciate that these ecosystems are in fact palimpsests shaped by multiple human cultures over millennia. We discuss two case studies of the Caribbean’s fragmented natural history collections, the effects of differing legislation and governance by the region’s multiple nation states. We use digital natural history specimen data from GBIF to demonstrate how...

From Poverty to Prosperity: The Real Energy Transition

Scott W. Tinker
The energy dialog varies by economic status. Western Europe and the United States suggest there is clean and renewable vs dirty and non-renewable energy, and further that clean energy is cheaper than dirty energy. In this narrative, carbon neutral drives the dialog. Some propose to eliminate coal, oil and even natural gas and nuclear altogether, and suggest that solar, wind and batteries can power the world and address climate change. The IEA just released a...

Relative Importance of Climate and Humans on Water Storage Changes using GRACE Satellite Data

Bridget R. Scanlon
Understanding climate and human impacts on water storage is critical for sustainable water-resources management. Here we assessed causes of total water storage (TWS) variability from GRACE satellites by comparison with climate forcing, particularly droughts and irrigation water use, in major aquifers in the U.S.. Results show that long-term variability in TWS from 2002 – 2020 tracked by GRACE satellites is dominated by interannual variability in most of the major aquifers. Low TWS trends in the...

Closely-spaced carbonate replacement veins: the influence of external stress on focused fluid flow during carbonation of peridotite

Manuel D. Menzel , Janos L. Urai & Estibalitz Ukar
The reaction of serpentinized peridotites with CO2-bearing fluids to listvenite (quartz-carbonate rocks) requires massive fluid flux and maintained permeability despite volume increase. Here we investigate listvenites and serpentinites samples from Hole BT1B of the Oman Drilling Project to improve our understanding of the mechanisms and feedbacks of fracturing and vein formation during peridotite carbonation. The samples are characterized by a high abundance of magnesite veins which are often bundled into closely-spaced, parallel sets. Relative cross-cutting...

Evolutionary gain and loss of a pathological immune response to parasitism

Daniel Bolnick, Jesse Weber, Natalie Steinel, Stephen De Lisle, Lauren Fuess, Foen Peng, Kum Chuan Shim, Brian Lohman & Swapna Subramanian
Parasites impose fitness costs on their hosts. Biologists often assume that natural selection favors infection-resistant hosts. Yet, when the immune response itself is costly, theory suggests selection may instead favor loss of resistance. Intraspecific variation in immune costs are rarely surveyed in a manner that tests evolutionary patterns, and there are few examples of adaptive loss of resistance. Here, we show that when marine threespine stickleback colonized freshwater lakes they gained resistance to the freshwater-associated...

Small mammal ARTS: Orion receiver data for site radiomapping and vole tracking, and scripts and results for localization and activity estimates

Gerard Wallace, Marija Elden, Rachel Boucher & Steven Phelps
This data set accompanies “An Automated Radio-Telemetry System (ARTS) for Monitoring Small Mammals”. The behavior of small fossorial mammals, such as voles, is extremely difficult to observe in natural environments. Small mammals were traditionally studied with labor intensive methods such as trapping and recapture or radio telemetry via homing, which require week/months of work and produce static home range estimates. In pursuit of better understanding natural history and behavioral ecology we implemented an automated radio...

Variation in female leverage: The influence of kinship and market effects on the extent of female power over males in Verreaux’s Sifaka

Rebecca Lewis, Gabrielle Bueno & Anthony Di Fiore
Female mammals employ reproductive strategies (e.g., internal gestation) that result in power asymmetries specific to intersexual dyads. Because the number of eggs available for fertilization at any given time for most mammals is quite limited, having a fertilizable egg is potentially an important source of economic power for females. Control over mating opportunities is a source of intersexual leverage for female Verreaux’s sifaka (Propithecus verreauxi). We examined economic factors thought to influence the value of...

Data from: Different evolutionary pathways lead to incomplete convergence of elongate body shapes in carnivoran mammals

Chris Law
Although convergence is often recognized as a ubiquitous feature across the Tree of Life, whether the underlying traits also exhibit similar evolutionary pathways towards convergent forms puzzles biologists. In carnivoran mammals, “elongate,” “slender,” and “long” are often used to describe and even to categorize mustelids (martens, polecats, and weasels), herpestids (mongooses), viverrids (civets and genets), and other carnivorans together. But just how similar these carnivorans are and whether there is convergence in the morphological component...

Highly resolved papilionoid legume phylogeny based on plastid phylogenomics

In-Su Choi, Domingos Cardoso, Luciano Queiroz, Haroldo Lima, Chaehee Lee, Tracey Ruhlman, Robert Jansen & Martin Wojciechowski
Comprising 501 genera and around 14,000 species, Papilionoideae is not only the largest subfamily of Fabaceae (Leguminosae; legumes), but also one of the most extraordinarily diverse clades among angiosperms. Papilionoids are a major source of food and forage, are ecologically successful in all major biomes, and display dramatic variation in both floral architecture and plastid genome (plastome) structure. Plastid DNA-based phylogenetic analyses have greatly improved our understanding of relationships among the major groups of Papilionoideae,...

Botando a lenha na fogueira do guató

Gustavo Godoy & Kristina Balykova
O povo guató ocupa duas terras indígenas no Brasil, uma em Mato Grosso e outra em Mato Grosso do Sul. A língua guató, criticamente ameaçada, conta com apenas dois falantes fluentes. Os dois não mantêm contato entre si e tampouco se relacionam cotidianamente com uma comunidade guató. Nesse cenário, a retomada da língua ancestral tem preocupado as lideranças de ambas as comunidades guató. No entanto, as diferenças na formação das duas terras indígenas contribuíram para...

What Am I - Chopped Suey?: Belonging and the Ambivalent Taste of American Exceptionalism

Label-based expectations affect reward perception in bumblebees

Claire Hemingway & Felicity Muth
While classic models of animal decision-making assume that individuals objectively assess the absolute value of options, decades of research have shown that rewards are often evaluated relative to prior experience, creating ‘contrast effects’. Contrast effects are often assumed to be purely sensory, yet consumer psychology tells us that label-based expectations can affect value perception. However, this has rarely been tested in non-model systems. Bumblebees forage on a variety of flower types that vary in their...

Population-level variation in parasite resistance due to differences in immune initiation and rate of response

Amanda Hund, Lauren Fuess, Mariah Kenney, Meghan Maciejewski, Joseph Marini, Kum Chuan Shim & Dan Bolnick
Closely related populations often differ in resistance to a given parasite, as measured by infection success or failure. Yet, the immunological mechanisms of these evolved differences are rarely specified. Does resistance evolve via changes to the host’s ability to recognize that an infection exists, actuate an effective immune response, or attenuate that response? We tested whether each of these phases of the host response contributed to threespine sticklebacks’ recently evolved resistance to their tapeworm Schistocephalus...

Microbiome assembly and maintenance across the lifespan of bumble bee workers

Tobin Hammer, August Easton-Calabria & Nancy A. Moran
How a host’s microbiome changes over its lifespan can influence development and aging. As these temporal patterns have only been described in detail for humans and a handful of other hosts, an important next step is to compare microbiome dynamics across a broader array of host-microbe symbioses, and to investigate how and why they vary. Here we characterize the temporal dynamics and stability of the bumblebee worker gut microbiome. Bumblebees are a useful symbiosis model...

Ice radar data from Little Dome C, Antarctica, 2016-2018

Robert Mulvaney, Edward King, Carlos Martin, Julius Rix, Marie Cavitte, Catherine Ritz & Massimo Frezotti
The dataset consists of 14 selected lines of radar data, collected from the Little Dome C region close to Concordia Station in East Antarctica. The data were collected in austral field seasons 2016-17, and 2017-18, from within the search region for the planned European project Beyond EPICA - Oldest Ice, an EU-funded 10-nation consortium project to drill an ice core that spans up to 1.5 million years of climate and atmospheric history. Radar lines were...

Global analysis of cell behavior and protein localization dynamics reveals region-specific functions for Shroom3 and N-cadherin during neural tube closure

Austin Baldwin, Juliana Kim, Hyemin Seo & John Wallingford
Failures of neural tube closure are common and serious birth defects, yet we have a poor understanding of the interaction of genetics and cell biology during neural tube closure. Additionally, mutations that cause neural tube defects (NTDs) tend to affect anterior or posterior regions of the neural tube but rarely both, indicating a regional specificity to NTD genetics. To better understand the regional specificity of cell behaviors during neural tube closure, we analyzed the dynamic...

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...

Sea-surface temperature anomalies mediate changes in fish richness and abundance in Western North Atlantic and Gulf of Mexico estuaries

Tobi Oke
Aim: Anthropogenic-driven warming of marine systems has resulted in a series of biological and physiological responses that are fundamentally altering ecosystem structure. Because estuaries exist at the land-ocean interface, they are particularly vulnerable to the effects of ocean warming as they can undergo rapid biogeochemical and hydrological shifts due to climate and land-use change. We explored how fish diversity structures—turnover, richness and abundance—have changed in the western North Atlantic and Gulf of Mexico estuaries through...

Data from 'Water table depth modulates productivity and biomass across Amazonian forests'

Silveira, Géraldine Derroire, Wendeson Castro, Abel Monteagudo Mendoza, Ademir Ruschel, Agustín Rudas, Adriano José Nogueira Lima, Agustín Rudas, Alejandro Araujo-Murakami, Ana Andrade, Anand Roopsind, Angelo Gilberto Manzatto, Anthony Di Fiore, Armando Torres-Lezama & Aurélie Dourdain

Reproductive benefits associated with dispersal in headwater populations of Trinidadian guppies (Poecilia reticulata)

Isabela Lima Borges, Jillian Dangerfield, Lisa Angeloni, Chris Funk & Sarah Fitzpatrick
Theory suggests that the evolution of dispersal is balanced by its fitness costs and benefits, yet empirical evidence is sparse due to the difficulties of measuring dispersal and fitness in natural populations. Here, we use spatially-explicit data from a multi-generational capture-mark-recapture study of two populations of Trinidadian guppies (Poecilia reticulata) along with pedigrees to test whether there are fitness benefits correlated with dispersal. Combining these ecological and molecular datasets allows us to directly measure the...

Can you hear/see me? Multisensory integration of signals does not always facilitate mate choice

Derek Coss, Michael Ryan, Rachel Page, Kimberly Hunter & Ryan Taylor
Females of many species choose mates using multiple sensory modalities. Multimodal noise may arise, however, in dense aggregations of animals communicating via multiple sensory modalities. Some evidence suggests multimodal signals may not always improve receiver decision-making performance. When sensory systems process input from multimodal signal sources, multimodal noise may arise and potentially complicate decision-making due to the demands on cognitive integration tasks. We tested female túngara frog, Physalaemus (=Engystomops) pustulosus, responses to male mating signals...
