Species-level tree crown maps improve predictions of tree recruit abundance in a tropical landscape

Cristina Barber, Sarah Graves, Jefferson Hall, Pieter Zuidema, Jodi Brandt, Stephanie Bohlman, Gregory Asner, Mario Bailón & T. Trevor Caughlin
Predicting forest recovery at landscape scales will aid forest restoration efforts. The first step in successful forest recovery is tree recruitment. Forecasts of tree recruit abundance, derived from the landscape-scale distribution of seed sources (i.e. adult trees), could assist efforts to identify sites with high potential for natural regeneration. However, previous work has revealed wide variation in the effect of seed sources on seedling abundance, from positive to no effect. We quantified the relationship between...

Body and wing morphology, flight metabolic rates, and wingbeat frequencies for 13 stingless bee species

Jon Harrison, Meghan Duell, David Roubik & C. Jaco Klok
Understanding the effect of body size on flight costs is critical for development of models of aerodynamics and animal energetics. Prior scaling studies that have shown that flight costs scale hypometrically have focused primarily on larger (> 100 mg) insects and birds, but most flying species are smaller. We studied the flight physiology of thirteen stingless bee species over a large range of body sizes (1-115 mg). Metabolic rate during hovering scaled hypermetrically (scaling slope...

Supplementary material and supplementary data files for: Handling logical character dependency in phylogenetic inference: Extensive performance testing of assumptions and solutions using simulated and empirical data

Tiago R. Simões, Oksana Vernygora, Bruno A. S. Medeiros & April M. Wright
Logical character dependency is a major conceptual and methodological problem in phylogenetic inference of morphological datasets, as it violates the assumption of character independence that is common to all phylogenetic methods. It is more frequently observed in higher-level phylogenies or in datasets characterizing major evolutionary transitions, as these represent parts of the tree of life where (primary) anatomical characters either originate or disappear entirely. As a result, secondary traits related to these primary characters become...

The gut microbiome variability of a butterflyfish increases on severely degraded Caribbean reefs

Friederike Clever, Jade M. Sourisse, Richard F. Preziosi, Jonathan A. Eisen, E. Catalina Rodriguez-Guerra, Jarrod J. Scott, Laetitia G.E. Wilkins, Andrew H. Altieri, W. Owen McMillan & Matthieu Leray
Environmental degradation has the potential to alter key mutualisms that underlie the structure and function of ecological communities. How microbial communities associated with fishes vary across populations and in relation to habitat characteristics remains largely unknown despite their fundamental roles in host nutrition and immunity. We find significant differences in the gut microbiome composition of a facultative coral-feeding butterflyfish (Chaetodon capistratus) across Caribbean reefs that differ markedly in live coral cover (∼0–30%). Fish gut microbiomes...

Tropical tree species differ in damage and mortality from lightning

Stephen P. Yanoviak, Jeannine Richards, Evan Gora, Cesar Gutierrez, Jeffrey Burchfield & Phillip Bitzer
Lightning is an important agent of mortality for large tropical trees with implications for tree demography and forest carbon budgets. We evaluated interspecific differences in susceptibility to lightning damage using a unique dataset of systematically located lightning strikes on Barro Colorado Island, Panama. We measured differences in mortality among trees damaged by lightning and related those to damage frequency and tree functional traits. Eighteen of 30 focal species had lightning mortality rates that deviated from...

Data from: A millennium of climatic and floristic dynamics in the Eastern Cordillera of the Colombian Andes

Alex Correa, Jaime Escobar, Broxton Bird, Dayenari Caballero-Rodríguez, Byron Steinman, Paula A. Rodríguez-Zorro & Jason Curtis
The transition from the Medieval Climate Anomaly (MCA, 950-1250 CE) to the Little Ice Age (LIA, 1350 to 1800 CE) is the largest pre-industrial climate shift within the last two millennia, offering an opportunity to study how vegetation responds to rapid climate change. We analyzed a sedimentary record from the Colombian Andes to reconstruct regional vegetation dynamics during this time interval, identify the modern environmental distribution of taxa present in the fossil record, and provide...

Rates of premature fruit drop for 201 plant species on Barro Colorado Island, Panama

Osvaldo Calderón, S. Joseph Wright, Sofia Gripenberg & Eleanor E. Jackson
Pre-dispersal seed mortality caused by premature fruit drop is a potentially important source of plant mortality, but one which has rarely been studied in the context of tropical forest plants. Of particular interest is premature fruit drop triggered by enemies, which – if density-dependent – could contribute to species co-existence in tropical forest plant communities. We used a long-term (31 year) dataset on seed and fruit fall obtained through weekly collections from a network of...

Scale-dependent environmental effects on phenotypic distributions in Heliconius butterflies

Ananda Regina Pereira Martins, Lucas Pereira Martins, Wing-Zheng Ho, W. Owen McMillan, Jonathan S. Ready & Rowan Barrett
Examining how environmental factors influence phenotypic distribution might provide valuable information about local adaptation, divergence, and speciation. The red-yellow Müllerian mimicry ring of Heliconius butterflies displays a wide range of color patterns across the Neotropics and is involved in several hybrid zones, making it an excellent system to study color phenotypic distribution. Using a multiscale distribution strategy, we studied whether different phenotypes of the distantly related species H. erato and H. melpomene, belonging to the...

Shifting balances in the weighting of sensory modalities are predicted by divergence in brain morphology in incipient species of Heliconius butterflies

Denise Dalbosco Dell'Aglio, W. Owen McMillan & Stephen Montgomery
Integrating and weighting sensory perception across modalities is crucial to how animals adapt to their environment. Divergence in brain structure is often in sensory processing regions, suggesting that investment reflects ecological needs. Here, we use two parapatric closely related species, Heliconius erato cyrbia and Heliconius himera, to test the hypothesis that divergence in sensory brain regions affects foraging decisions. These butterflies are isolated across an ecological gradient, which is linked to differences in brain morphology,...

Demographic rates and stature of tree species in 13 sub-tropical forests: annual growth, annual survival, annual recruitment >( 1 cm dbh), stature (max dbh)

Stephan Kambach, Richard Condit, Salomón Aguilar, Helge Bruelheide, Sarayudh Bunyavejchewin, Chia-Hao Chang-Yang, Yu-Yun Chen, George Chuyong, Stuart J. Davies, Sisira Ediriweera, Corneille E. N.

Mohamad, Nantachai Pongpattananurak, Rolando Pérez, Lillian Jennifer V. Rodriguez, I-Fang Sun … & Nadja Rüger
Organisms of all species must balance their allocation to growth, survival and recruitment. Among tree species, evolution has resulted in different life-history strategies for partitioning resources to these key demographic processes. Life-history strategies in tropical forests have often been shown to align along a trade-off between fast growth and high survival, i.e. the well-known fast-slow continuum. In addition, an orthogonal trade-off has been proposed between tall stature – resulting from fast growth and high survival...

Data for: Ear pinnae in a neotropical katydid (Orthoptera: Tettigoniidae) function as ultrasound guides for bat detection

Fernando Montealegre-Z, Christian Pulver, Emine Celiker, Charlie Woodrow, Inga Geipel, Carl D Soulsbury, Darron A Cullen, Stephen M Rogers & Daniel Veitch
Early predator detection is a key component of the predator-prey arms race and has driven the evolution of multiple animal hearing systems. Katydids (Insecta) have sophisticated ears, each consisting of paired tympana on each foreleg that receive sound both externally, through the air, and internally via a narrowing ear canal running through the leg from an acoustic spiracle on the thorax. These ears are pressure-time difference receivers capable of sensitive and accurate directional hearing across...

Spatial learning overshadows learning odors and sounds in both predatory and frugivorous bats

M. May Dixon, Gerald Carter, Michael Ryan & Rachel Page
To forage efficiently, animals should selectively attend to and remember the cues of food that best predict future meals. One hypothesis is that animals with different foraging strategies should vary in their reliance on spatial versus feature cues. Specifically, animals that store food in dispersed caches or that feed on spatially stable food, like fruit or flowers, should be relatively biased to learning a meal’s location, whereas predators that hunt mobile prey should instead be...

Phylogeography of the sea urchin genus Echinothrix.

Simon Coppard, Harilaos Lessios & Holly Jessop
The sea urchins Echinothrix calamaris and E. diadema have sympatric distributions throughout the Indo-Pacific. Diverse colour variation is reported in both species. To reconstruct the phylogeny of the genus and assess gene flow across the Indo-Pacific we sequenced mitochondrial 16S rDNA, ATPase-6, and ATPase-8, and nuclear 28S rDNA and the Calpain-7 intron. Our analyses revealed that E. diadema formed a single trans-Indo-Pacific clade, but E. calamaris contained three discreet clades. One clade was endemic to...

Data from: Rapid radiation in a highly diverse marine environment

Kosmas Hench, W. Owen McMillan, Oscar Puebla & Martin Helmkampf
Rapid diversification is often observed when founding species invade isolated or newly formed habitats that provide ecological opportunity for adaptive radiation. However, most of the Earth’s diversity arose in diverse environments where ecological opportunities appear to be more constrained. Here, we present a striking example of a rapid radiation in a highly diverse marine habitat. The hamlets, a group of reef fishes from the wider Caribbean, have radiated into a stunning diversity of color patterns...

Response of tree species to environmental gradients was estimated. The soil and climate data are provided in a single table here. Tree distributions are published at Condit et al. (2013a), including a data archive in Condit et al. (2013b). Note that the PNAS article incorrectly cites...

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...

Genome-wide sequence data show no evidence of hybridization and introgression among pollinator wasps associated with a community of Panamanian strangler figs

Jordan Satler, Allen Herre, Tracy Heath, Carlos Machado, Adalberto Gomez & John Nason
The specificity of pollinator host choice influences opportunities for reproductive isolation in their host plants. Similarly, host plants can influence opportunities for reproductive isolation in their pollinators. For example, in the fig and fig wasp mutualism, offspring of fig pollinator wasps mate inside the inflorescence that the mothers pollinate. Although often host specific, multiple fig pollinator species are sometimes associated with the same fig species, potentially enabling hybridization between wasp species. Here we study the...

Volatility in coral cover erodes niche structure, but not diversity, in reef fish assemblages

Cheng-Han Tsai, Hugh Sweatman, Löic Thibaut & Sean Connolly
Environmental fluctuations are becoming increasingly volatile in many ecosystems, highlighting the need to better understand how stochastic and deterministic processes shape patterns of commonness and rarity, particularly in high-diversity systems like coral reefs. We analyzed reef fish time-series across the Great Barrier Reef to show that approximately 75% of the variance in relative species abundance is attributable to deterministic, intrinsic species differences. Nevertheless, the relative importance of stochastic factors is markedly higher on reefs that...

Factors limiting plant recruitment in a Tropical Afromontane Forest

Iveren Abiem, Ian Dickie, David Kenfack & Hazel Chapman
Predicting how forest species composition may change in response to global change is essential for meaningful management. Which species are most likely to successfully recruit depends on a multitude of factors, but processes operating at the seed-to-seedling transition being especially important. Here we explore how insufficient seed dispersal (dispersal limitation) and ecological filtering of seedlings (establishment limitation) influence species recruitment in an Afromontane Forest. We combined census data from seeds in seed traps and seed-seedling...

Pollinator and host sharing lead to hybridization and introgression in Panamanian free-standing figs, but not in their pollinator wasps

Jordan Satler, Allen Herre, Tracy Heath, Carlos Machado, Adalberto Gomez, Charlotte Jander, Deren Eaton & John Nason
Obligate pollination mutualisms, in which plant and pollinator lineages depend on each other for reproduction, often exhibit high levels of species-specificity. However, cases in which two or more pollinator species share a single host species (host sharing), or two or more host species share a single pollinator species (pollinator sharing), are known to occur in the current ecological time. Further, evidence for host switching in evolutionary time is increasingly being recognized in these systems. The...
