Climate change and lithium mining influence flamingo abundance in the Lithium Triangle

Jorge Gutiérrez, Johnnie Moore, Patrick Donnelli, Cristina Dorador, Juan Navedo & Nathan Senner
The development of technologies to slow climate change has been identified as a global imperative. Nonetheless, such ‘green’ technologies can potentially have negative impacts on biodiversity. We explored how climate change and the mining of lithium for green technologies influence surface water availability, primary productivity, and the abundance of three threatened and economically important flamingo species in the ‘Lithium Triangle’ of the Chilean Andes. We combined climate and primary productivity data with remotely sensed measures...

The influence of genderless appeal on preference for highly aesthetic products

Yi SU, Yunlu Yin & Ruoou Li
The experiment explores the moderating role of gender fluidity in the relationship between genderless appeals and preference for highly aesthetic products.

Dynamic sensitivity to resource availability influences population responses to mismatches in a shorebird

Luke Wilde, Josiah Simmons, Rose Swift & Nathan Senner
Climate change has caused shifts in seasonally recurring biological events leading to the temporal decoupling of consumer-resource pairs – i.e., phenological mismatching. Although mismatches often affect individual fitness, they do not invariably scale up to affect populations, making it difficult to assess the risk they pose. Individual variation may contribute to this inconsistency, with changes in resource availability and consumer needs leading mismatches to have different outcomes over time. Nevertheless, most models estimate a consumer’s...

Stability and properties of substituted cobaltocenium

Sophya Garashchuk & Shehani Wetthasinghe
This page provides the bond dissociation energies (BDEs) of disubstituted cobaltocenium complexes and few other geometric and chemical properties such as dipole moment, Hirshfeld charge, polarizability, highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) energies of the complexes and their fragments.

Adaptation to a bacterial pathogen in Drosophila melanogaster is not aided by sexual selection

Sakshi Sharda, Tadeusz Kawecki & Brian Hollis
Theory predicts that sexual selection should aid adaptation to novel environments, but empirical support for this idea is limited. Pathogens are a major driver of host evolution and, unlike abiotic selection pressures, undergo epidemiological and co-evolutionary cycles with the host involving adaptation and counteradaptation. Because of this, populations harbor ample genetic variation underlying immunity and the opportunity for sexual selection based on condition-dependent “good genes” is expected to be large. In this study, we evolved...

Emplacement of massive deposits by sheet flow

Ricardo Hernandez‐Moreira, Sadegh Jafarinik, Sydney Sanders, Christopher G. St. C. Kendall, Gary Parker & Enrica Viparelli
Relatively common to the submarine setting are depositional sequences that begin with a lower erosional boundary, followed in ascending order by a either a graded or an inherently massive basal unit, a relatively coarse parallel laminated unit, a cross laminated unit, a relatively fine parallel laminated unit, and a capping layer of massive mud. These sequences are present in turbidity current, coastal storm and tsunami deposits, and their study is the key to understanding the...

Carry-over effects of larval food stress on adult energetics and life history in a nectar-feeding butterfly

Carol Boggs & Kristjan Niitepold
Stressful juvenile developmental conditions can affect performance and fitness later in life. In holometabolous insects such as butterflies, development under stressful conditions may lead to smaller adult size, lower reproductive output and shorter lifespan. However, how larval developmental stress affects energy intake and expenditure in adult individuals is poorly understood. We subjected last-instar larvae of Speyeria mormonia Edwards (Lepidoptera: Nymphalidae) to periodic dietary restriction (DR) to examine the allocation of energy and nutrients among different...

Influence of sand supply and grain size on upper regime bedforms

Sydney Sanders, Sadegh Jafarinik, Ricardo Hernandez Moreira, Ryan Johnson, Amanda Balkus, Mahsa Ahmadpoor, Brandon Fryson, Briana McQueen, Juan Fedele & Enrica Viparelli
Notwithstanding the large number of studies on bedforms such as dunes and antidunes, performing quantitative predictions of bedform type and geometry remains an open problem. Here we present the results of laboratory experiments specifically designed to study how sediment supply and caliber may impact equilibrium bedform type and geometry in the upper regime. Experiments were performed in a sediment feed flume with flow rates varying between 5 l/s and 30 l/s, sand supply rates varying...

Islands Within Islands: Bacterial Phylogenetic Structure and Consortia in Hawaiian Lava Caves and Fumaroles

Rebecca Prescott, Tatyana Zamkovaya, Stuart Donachie, Diana Northup, Joseph Mendley, Natalia Monsalve, Jimmy Saw, Alan Decho, Patrick Chain & Penelope Boston
Lava caves, tubes, and fumaroles in Hawai‘i present a range of volcanic, oligotrophic environments from different lava flows and host unexpectedly high levels of bacterial diversity. These features provide an opportunity to study the ecological drivers that structure bacterial community diversity and assemblies in volcanic ecosystems and compare the older, more stable environments of lava tubes, to the more variable and extreme conditions of younger, geothermally active caves and fumaroles. Using 16S rRNA amplicon-based sequencing...

Adaptation to lower latitudes and lower elevations precedes the evolution of hummingbird pollination in western North American Penstemon

Carolyn Wessinger & Ashley Hamilton
Premise: A switch in pollinator can occur when a plant lineage enters a new habitat where the ancestral pollinator is less common and a novel pollinator is more common. Since pollinator communities vary according to environmental tolerances and availability of resources, there may be consistent associations between pollination mode and specific regions and habitats. Such associations can be studied in lineages that have experienced multiple pollinator transitions, representing evolutionary replicates. Methods: Our study focused on...

Data from: Behavioral adjustments in the social associations of a precocial shorebird mediate the costs and benefits of grouping decisions

Luke Wilde, Rose Swift & Nathan Senner
Animals weigh multiple costs and benefits when making grouping decisions. The cost-avoidance grouping framework proposes that group density, information quality, and risk affect an individual’s preference for con- or heterospecific groups. However, this assumes the cost-benefit balance of a particular grouping is constant spatiotemporally, which may not always be true. Investigating how spatiotemporal context influences grouping choices is therefore key to understanding how animals contend with changing conditions. Changes in body size during development lead...
