Source data for: Nesting success of Red-winged Blackbirds (Agelaius phoeniceus) in marshes in an anthropogenic landscape

Scott Robinson & Holly McChesney
Recent analyses show significant population declines in many abundant avian species, especially marsh-nesting species including the Red-winged Blackbird (RWBL). Hypothesized causes include reduced nesting success resulting from changing land use patterns and exposure to contaminants. Our goal was to test the hypothesis that landscape and nest characteristics as well as exposure to polychlorinated biphenyls (PCBs) correlate with nesting success. From 2008-2014, we measured clutch size, egg and nestling mass, hatching and fledging success, and daily...

Peeling back the layers: First phylogenomic insights into the Ledebouriinae (Scilloideae, Asparagaceae)

Cody Howard, Andrew Crowl, Timothy Harvey & Nico Cellinese
The Ledebouriinae (Scilloideae, Asparagaceae) are a widespread group of bulbous geophytes found predominantly throughout seasonal climates in sub-Saharan Africa, with a handful of taxa in Madagascar, the Middle East, India, and Sri Lanka. Phylogenetic relationships within the groups have been historically difficult to elucidate. Here, we provide the first phylogenomic perspective into the Ledebouriinae. Using the Angiosperms353 targeted enrichment probe set, we consistently recovered four major clades (i.e., two Ledebouria clades, Drimiopsis, and Resnova). The...

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...

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...

A high-throughput multispectral imaging system for museum specimens

Wei-Ping Chan, Richard Anthony Rabideau Childers, Sorcha Ashe, Cheng-Chia Tsai, Caroline Elson, Kirsten Joanna Keleher, Rachel L. Hawkins Sipe, Crystal A. Maier, Andrei Sourakov, Lawrence F. Gall, Gary D. Bernard, Edward R. Soucy, Nanfang Yu & Naomi E. Pierce
We present an economical imaging system with integrated hardware and software to capture multispectral images of Lepidoptera with high efficiency. This method facilitates the comparison of colors and shapes among species at fine and broad taxonomic scales and may be adapted for other insect orders with greater three-dimensionality. Our system can image both the dorsal and ventral sides of pinned specimens. Together with our processing pipeline, the descriptive data can be used to systematically investigate...

A new approach using targeted sequence capture for phylogenomic studies across Cactaceae

Serena Acha & Lucas Majure
Relationships within the major clades of Cactaceae are relatively well known based on DNA sequence data mostly from the chloroplast genome. Nevertheless, some nodes along the backbone of the phylogeny, and especially generic and species-level relationships, remain poorly resolved and are in need of more informative genetic markers. In this study, we propose a new approach to solve the relationships within Cactaceae, applying a targeted sequence capture pipeline. We designed a custom probe set for...

Variable vulnerability to climate change in New Zealand lizards

Scott Jarvie, Travis Ingram, David Chapple, Rodney Hitchmough, Stuart Nielsen & Joanne M. Monks
Aim: The primary drivers of species and population extirpations have been habitat loss, overexploitation, and invasive species, but human-mediated climate change is expected to be a major driver in future. To minimise biodiversity loss, conservation managers should identify species vulnerable to climate change and prioritise their protection. Here, we estimate climatic suitability for two speciose taxonomic groups, then use phylogenetic analyses to assess vulnerability to climate change. Location: Aotearoa New Zealand (NZ) Taxa: NZ lizards:...

Niche dynamics of Memecylon in Sri Lanka: distribution patterns, climate change effects, and conservation priorities

Prabha Amarasinghe, Narayani Barve, Hashendra Kathriarachchi, Bette Loiselle & Nico Cellinese
Aim: Recent climate projections have shown that the distribution of organisms in island biotas is highly affected by climate change. Here, we present the results of the analysis of niche dynamics of a plant group, Memecylon on Sri Lanka, an island, using species occurrences and climate data. We aim to determine which climate variables explain current distribution, model how climate change impacts the availability of suitable habitat for Memecylon, and determine conservation priority areas for...

Data from: Widespread bird species show idiosyncratic responses in residual body mass to selective logging and edge effects in the Colombian Western Andes

Harrison Jones, Gabriel Colorado & Scott Robinson
This dataset consists of banding data (N = 1589 captures, 129 bird species), including morphological and breeding biology measures, collected from understory birds in subtropical cloudforest at roughly 2000 m.a.s.l. in the municipality of El Cairo in Colombia's Western Andes (Serrania de los Paraguas range). Roughly 8,350 net hours were divided into two three-month field seasons (June-August 2017 and January-March 2018), both corresponding to local dry seasons. Birds were banded along 500-meter transects in forest...

Dancing drives evolution of sexual size dimorphism in manakins

Elsie H. Shogren, Marina Anciães, Julia Barske, César Cestari, Emily H. DuVal, Milene G. Gaiotti, Erik I. Johnson, Rebecca T. Kimball, Miguel A. Marini, T. Brandt Ryder, Micah N. Scholer, Judit Ungvári, Stewart A. White & W. Alice Boyle
Body size mediates life history, physiology, and inter- and intra-specific interactions. Within species, sexes frequently differ in size, reflecting divergent selective pressures and/or constraints. Both sexual selection and differences in environmentally-mediated reproductive constraints can drive sexual size dimorphism, but empirically testing causes of dimorphism is challenging. Manakins (Pipridae), a family of Neotropical birds comprising ~50 species, exhibit both male- and female-biased size dimorphism and are distributed across gradients of precipitation and elevation. Males perform courtship...
