Predator-based selection and the impact of edge sympatry on components of coral snake mimicry

Lauren Wilson, George Lonsdale, John David Curlis, Elizabeth Hunter & Christian L. Cox
Mimicry is a vivid example of how predator-driven selection can impact phenotypic diversity, which itself can be influenced by the presence (sympatry) or absence (allopatry) of a dangerous model. However, the impact of sympatry and allopatry on predation on mimicry systems at fine spatial scales (e.g., edge sympatry, allopatry) is not well understood. We used a clay model study in a montane tropical site in Honduras to test the impact of edge sympatry on 1)...

A taxonomic revision of the Lathberry Clade of Eugenia (Myrtaceae)

Jonathan A. Flickinger, Eugenio Santiago-Valentín, José A. Sustache-Sustache & Omar A. Monsegur-Rivera
The Lathberry Clade includes seven species of Eugenia sect. Umbellatae (Myrtaceae) distributed from Puerto Rico through the Lesser Antilles. Members of the Lathberry Clade are trees and shrubs distinguished from other Antillean species by a combination of dull twigs, glabrous leaves with a raised midvein, glomerate or fasciculate inflorescences predominantly borne below the leaves on old wood, closely spaced and ascending inflorescence bracts, spheroidal fruits turning red or purple at maturity, the calyx lobes erect...

Data from: Resolving the mesoscopic missing link: biophysical modeling of EEG from cortical columns in primates

Jacob Westerberg, Beatriz Herrera, Michelle Schall, Alexander Maier, Geoffrey Woodman, Jeffrey Schall & Jorge Riera
Event-related potentials (ERP) are among the most widely measured indices for studying human cognition. While their timing and magnitude provide valuable insights, their usefulness is limited by our understanding of their neural generators at the circuit level. Inverse source localization offers insights into such generators, but their solutions are not unique. To address this problem, scientists have assumed the source space generating such signals comprises a set of discrete equivalent current dipoles, representing the activity...

Carbon dioxide and blood-feeding shift visual cue tracking during navigation in Aedes aegypti mosquitoes

Elina Barredo, Joshua Raji, Michael Ramon, Matthew DeGennaro & Jamie Theobald
Hematophagous mosquitoes need a blood meal to complete their reproductive cycle. To accomplish this, female mosquitoes seek vertebrate hosts, land on them, and bite. As their eggs mature, they shift attention away from hosts and towards finding sites to lay eggs. We asked whether females were more tuned to visual cues when a host-related signal, carbon dioxide, was present, and further examined the effect of a blood meal, which shifts behavior to ovipositing. Using a...

Using the Area of Habitat to assess the extent of protection of India's birds

Ashwin Warudkar, Naman Goyal, Varun Kher, Vinay KL, Ritobroto Chanda, Raja Bandi, Clinton Jenkins, & Stuart Pimm
India hosts multiple global biodiversity hotspots while being one of the most populous countries in the world. Here, we examine how well India has protected its avifauna, based on the fraction of their ranges falling within “protected areas.” India has protected 5% of its land this way. The issue is whether India has done better than expected in protecting its threatened species. To this end, we assessed 99 Near Threatened, Threatened, and small-ranged species by...

Literature review dataset on predation-risk effects

Scott Peacor, David Kimbro, Nathan Dorn, Justine Smith, Michael Sheriff & Michael Cherry
A well-accepted narrative in ecology is that prey modify traits to reduce predation risk, and the trait modification has costs large enough to cause ensuing demographic, trophic and ecosystem consequences, with implications for conservation, management, and agriculture. But ecology has a long history of emphasizing that quantifying the importance of an ecological process ultimately requires evidence linking a process to unmanipulated field patterns. We suspected that such process-linked-to pattern (PLP) studies were poorly represented in...

Bamboo climatic tolerances are decoupled from leaf functional traits across an Andean elevation gradient

Belen Fadrique, Chris Baraloto, Catherine Bravo-Avila & Kenneth Feeley
Widespread changes in temperature and precipitation patterns present plant species with new and combined stresses that affect their performance and distribution. Functional traits are indicators of plant resource use-acquisition strategies and thus they are commonly used to understand the geographic distributions of plant species and species’ potential responses to climate change. To date, most studies have targeted a few easy-to-measure leaf traits even though other traits, such as climatic tolerances, could provide valuable information directly...

Salinity Legacy: Foliar microbiome’s history affects mutualist-conferred salinity tolerance

Suresh Subedi, Preston Allen, Rosario Vidales, Leonel Sternberg, Michael Ross & Michelle Afkhami
The rapid human-driven changes in the environment during the Anthropocene have placed extreme stress on many plants and animals. Beneficial interactions with microorganisms may be crucial for ameliorating these stressors and facilitating the ecosystem services host organisms provide. Foliar endophytes, microorganisms that reside within leaves, are found in essentially all plants and can provide important benefits (e.g., enhanced drought tolerance or resistance to herbivory). However, it remains unclear how important the legacy effects of the...

Sergestidae shrimp family single- and multi-gene alignments and tree files

Charles Golightly & Heather Bracken-Grissom
Deep-sea shrimp belonging to the family Sergestidae provide a unique system for studying the evolution of bioluminescence. Most species within the family possess autogenic bioluminescent photophores in one of three distinct forms: lensed photophores, non-lensed photophores, or internal organs of Pesta. This morphological diversity across Sergestidae has resulted in recent major taxonomic revisions, dividing the two major genera (Sergia and Sergestes) into 15. Here, we capitalize on molecular data to construct an updated genus-level phylogeny...

Data from: Mycorrhizal symbiosis pathway and edaphic fertility frame root economics space among tree species

Han Yan, Grégoire T. Freschet, Huimin Wang, J. Aaron Hogan, Shenggong Li, Oscar J. Valverde-Barrantes, Xiaoli Fu, Ruili Wang, Xiaoqin Dai, Lei Jiang, Shengwang Meng, Fengting Yang, Miaomiao Zhang & Liang Kou
The root economics space (RES) is multidimensional and largely shaped by belowground biotic and abiotic influences. However, how root-fungal symbioses and edaphic fertility drive this complexity remains unclear. Here, we measured absorptive root traits of 112 tree species in temperate and subtropical forests of China, including traits linked to functional differences between arbuscular mycorrhizal (AM) and ectomycorrhizal (ECM) hosts. Our data, from known mycorrhizal tree species, revealed a ‘fungal-symbiosis’ dimension distinguishing AM from ECM species....

Sighting, group composition, and tactile exchange for a study on Atlantic spotted dolphins around Bimini, The Bahamas

Nicole Danaher-Garcia
Interactions between mammalian social groups are generally antagonistic as individuals in groups cooperate to defend resources from non-members. Members of the family Delphinidae inhabit a three-dimensional habitat where resource defense is usually impractical. Here, we describe a long-term partial fusion of two communities of Atlantic spotted dolphins (Stenella frontalis). The northern community, studied for 30 years, immigrated 160 km to the range of the southern community, observed for 20 years. Both communities featured fission-fusion grouping...

The global distribution of known and undiscovered ant biodiversity

Jamie Kass, Benoit Guénard, Kenneth Dudley, Clinton Jenkins, Fumika Azuma, Brian Fisher, Catherine Parr, Heloise Gibb, John Longino, Philip Ward, Anne Chao, David Lubertazzi, Michael Weiser, Walter Jetz, Robert Guralnick, Rumsaïs Blatrix, James Des Lauriers, David Donoso, Christos Georgiadis, Kiko Gomez, Peter Hawkes, Robert Johnson, John Lattke, Joe MacGown, William Mackay … & Evan Economo
Invertebrates constitute the majority of animal species and are critical for ecosystem functioning and services. Nonetheless, global invertebrate biodiversity patterns and their congruences with vertebrates remain largely unknown. We resolve the first high-resolution (~20-km) global diversity map for a major invertebrate clade, ants, using biodiversity informatics, range modeling, and machine learning to synthesize existing knowledge and predict the distribution of undiscovered diversity. We find that ants and different vertebrate groups have distinct features in their...

Riparian buffers provide refugia during secondary forest succession

Michelle E. Thompson, Brian J. Halstead & Maureen A. Donnelly
Aim Secondary forests regenerating from human disturbance are increasingly becoming a predominant forest type in many regions, and they play a significant role in forest community dynamics. Understanding the factors that underlie the variation in species responses during secondary succession is important for understanding community assembly and biodiversity monitoring and management. Because species vary in ecology and behavior, responses to ecosystem change should vary among species. Here, we show that habitat type (riparian, upland), phylogeny,...

A general swimming response in exhausted obligate swimming fish

Gil Iosilevskii, Jacinta Kong, Carl Meyer, Yuuki Watanabe, Yannis Papastamatiou, Mark Royer, Itsumi Nakamura, Katsufumi Sato, Thomas Doyle, Luke Harman, Jonathan Houghton, Adam Barnett, Jayson Semmens, Niall Ó Maoléidigh, Alan Drumm, Ross O'Neill, Daniel Coffey & Nicholas Payne
Marine organisms normally swim at elevated speeds relative to cruising speeds only during strenuous activity, such as predation or escape. We measured swimming speeds of 29 ram ventilating sharks from 10 species and of three Atlantic bluefin tunas immediately after exhaustive exercise (fighting a capture by hook-and-line), and unexpectedly found all individuals exhibited a uniform mechanical response, with swimming speed initially 2 times higher than the cruising speeds reached approximately 6 hours later. We hypothesised...
