Raw data from: Differentiating siliceous particulate matter in the diets of mammalian herbivores

Luke Fannin, Elise Laugier, Adam Van Casteren, Sabrina Greenwood & Nathaniel Dominy
1. Silica is crucial to terrestrial plant life and geochemical cycling on Earth. It is also implicated in the evolution of mammalian teeth, but there is debate over which type of siliceous particle has exerted the strongest selective pressure on tooth morphology. 2. Debate revolves around the amorphous silica bodies (phytoliths) in plants and forms of siliceous grit––i.e., crystalline quartz (sand, soil, dust)––on plant surfaces. The problem is that conventional measures of silica often quantify...

Influence of the evolution of cultural landscapes as heritage on 20th century international heritage preservation doctrine

Cari Goetcheus & Nora J. Mitchell
The Athens and Venice charters are generally considered the philosophical foundation of modern heritage preservation. Throughout the 20th century, preservation practitioners have continually debated these early doctrines, especially as they’ve been applied to increasingly diverse places in ever-changing social contexts. As important shifts in heritage preservation theory have evolved, a broad range of values have extended the definition of cultural heritage from monument-specific sites to larger landscapes, from local to regional and national scales, from...

The initiation and growth of transpressional shear zones through continental arc lithosphere, southwest New Zealand

Keith Klepeis, Joshua Schwartz, Elena Miranda, Peter Lindquist, Richard Jongens, Rose Turnbull & Harold Stowell
Structural analyses combined with new U-Pb zircon and titanite geochronology show how two Early Cretaceous transpressional shear zones initiated and grew through a nearly complete section of continental arc crust during oblique convergence. Both shear zones reactivated Carboniferous faults that penetrated the upper mantle below Zealandia’s Median Batholith but show opposite growth patterns and dissimilar relationships with respect to arc magmatism. The Grebe-Indecision Creek shear zone was magma-starved and first reactivated at ~136 Ma as...

The eco-evolutionary history of Madagascar presents unique challenges to tropical forest restoration

Katherine A. Culbertson, Timothy L.H. Treuer, Ariadna Mondragon Botero, Tanjona Ramiadantsoa & J. Leighton Reid
High biodiversity and endemism combined with persistently high deforestation rates mark Madagascar as one of the hottest of biodiversity hotspots. Contemporary rising interest in large-scale reforestation, both globally and throughout Madagascar itself, presents a promising impetus for forest restoration and biodiversity conservation across the island. However, Madagascar may face unique restoration challenges due to its equally unique eco-evolutionary trajectory, which must be understood to enable successful ecological restoration. We conducted a systematic review of potential...

Pollinator visitation to Na-enriched plants

Nathan Sanders & Carrie Finkelstein
Plants have evolved a variety of approaches to attract pollinators, including enriching their nectar with essential nutrients. Because sodium is an essential nutrient for pollinators, and sodium concentration in nectar can vary both within and among species, we explored whether experimentally enriching floral nectar with sodium in five plant species would influence pollinator visitation and diversity. We found that the number of visits by pollinators increased on plants with sodium-enriched nectar, regardless of plant species,...

Abundance data of anuran species in forest fragments

M Almeida-Gomes, NJ Gotelli, CFD Rocha, MV Vieira & JA Prevedello
Understanding the effects of random versus niche-based processes on biodiversity patterns is a central theme in ecology, and an important tool for predicting effects of habitat loss and fragmentation on biodiversity. We investigated the predictive power of random processes to explain species richness and species dissimilarity of amphibian assemblages in a fragmented tropical landscape of the Atlantic Forest of South America. We analyzed a large database of amphibian abundance and occupancy, sampled in 21 forest...

Data from: Comparative impacts of long-term trends in snowmelt and species interactions on plant population dynamics

Diane Campbell, Diane Campbell, Mary Price, Nick Waser, Rebecca Irwin & Alison Brody
Climate change can impact plant fitness and population persistence directly through changing abiotic conditions and indirectly through its effects on species interactions. Pollination and seed predation are important biotic interactions that can impact plant fitness, but their impact on population growth rates relative to the role of direct climatic effects is unknown. We combined 13 years of experiments on pollen limitation of seed set and pre-dispersal seed predation in Ipomopsis aggregata, a subalpine wildflower, with...

Genomic Standards Consortium (GSC) Island Sampling Day: Moorea Reef to Ridges Genomic Transect

Erin Robinson
Here we describe a project that supports the mission of the Genomic Standards Consortium (GSC) and contributes to the “Ocean Biomolecular Observations Network” (OBON) and the “Ocean Best Practice System” (OBPS - Omics Task Team), flagship programs of the UN Ocean Decade of Ocean Science for Sustainable Development. The project serves as a test case for two related infrastructure projects that aim to improve standards, policies, and best practices in sample collection: Sampling Nature (SN)...

Data from: Seeing the Forest for the trees: Assessing genetic offset predictions from Gradient Forest

Áki Jarl Láruson, Matthew Fitzpatrick, Stephen Keller, Benjamin Haller & Katie Lotterhos
Gradient Forest (GF) is a machine learning algorithm designed to analyze spatial patterns of biodiversity as a function of environmental gradients. An offset measure between the GF predicted environmental association of adapted alleles and a new environment (GF Offset), is increasingly being used to predict the loss of environmentally adapted alleles under rapid environmental change, but remains mostly untested for this purpose. Here we explore the robustness of GF Offset to assumption violations, and its...

Naturecultures guidance: steps in our journey

Kristal Buckley, Leticia Leitao, Nora J. Mitchell, Maya Ishizawa, Jessica L. Brown, Nicole Franceschini & Steve H. Brown
The emergence of cultural landscapes concepts heralded important mindset shifts in heritage practices. These have underpinned development of landscape approaches that recognise larger-scale interactions and the relationships between natural and cultural elements and processes. However, it has become apparent that an enduring nature-culture binary in heritage practices can result in adverse outcomes ‘on the ground’. The ISCCL has provided a forum and a source of global leadership for these issues, including the exploration of the...

Functional traits and metacommunity theory reveal that habitat filtering and competition maintain bird diversity in a human shared landscape

Harold N. Eyster, Diane Srivastava, Maayan Kreitzman & Kai Chan
Human shared landscapes cover much of Earth, yet their conservation value is contested. This controversy may persist because previous studies have examined species diversity, rather than the processes through which such diversity is maintained. For example, a site exhibiting high diversity may not actually bolster populations if the diversity is only maintained through net immigration. Recent research has begun to isolate the processes that maintain metacommunities and develop functional trait methods to identify these processes....

Importance of invasion mechanisms varies with abiotic context and plant invader growth form

Mariana C. Chiuffo, Jaime Moyano, Nahuel Policelli, Agostina Torres, Agustin Vitali, Martin Nuñez & Mariano Rodriguez-Cabal
1. Many invasion hypotheses propose biotic interactions as the main mechanism to explain non-native species' success. Despite the evidence that the strength of biotic interactions varies with abiotic context, it remains unclear whether the importance of the different mechanisms proposed to explain invasion predictably varies with abiotic context and whether this variation is consistent across different growth forms. 2. We reviewed studies at a global scale to evaluate whether evapotranspiration, latitude, precipitation, and temperature influence...

A global phylogenomic study of the Thelypteridaceae

Susan Fawcett, Alan Smith, Michael Sundue, Gordon Burleigh, Emily Sessa, Li-Yaung Kuo, Cheng-Wei Chen, Weston Testo, Michael Kessler & David Barrington
The generic classification of the Thelypteridaceae has been the subject of much controversy. Proposed taxonomic systems have varied from recognizing more than 1000 species in the family within the single genus Thelypteris, to systems favoring upwards of 30 genera. Insights on intrafamilial relationships have been gained from recent phylogenetic studies, especially for the Neotropics; however, in the most recent classification, 10 of 30 recognized genera are either non-monophyletic or untested. In the present study, we...
