Ecological and Genomic Attributes of Novel Bacterial Taxa That Thrive in Subsurface Soil Horizons
(American Society for Microbiology, 2019-10-01)While most bacterial and archaeal taxa living in surface soils remain undescribed, this problem is exacerbated in deeper soils, owing to the unique oligotrophic conditions found in the subsurface. Additionally, previous ... -
Notes on the classification of <i>Ctenocolletes</i> (Hymenoptera: Stenotritidae)
(2019-12-23)Three new subgenera are established within the Australian bee genus Ctenocolletes Cockerell (Stenotritidae). Three species are placed in Ctenocolletopsis Engel, new subgenus, distinguished most notably by the absence of ... -
On the classification of North American <i>Chelostoma</i> (Hymenoptera: Megachilidae)
(2019-09-30)A new subgenus of Chelostoma Latreille is established for the New World group historically placed in Foveosmia Warncke. These species, placed herein in Neochelostoma Engel & Griswold, new subgenus, are differentiated from ... -
New species of the augochlorine bee genus <i>Stilbochlora</i>, with a preliminary key (Hymenoptera: Halictidae)
(2019-09-05)Three new species of the augochlorine bee genus Stilbochlora Engel et al. (Halictinae: Augochlorini) are described and figured from Peru. The new species are distinct from the type species, Stilbochlora eickworti (Engel ... -
Notes on Papuasian and Malesian stingless bees, with the descriptions of new taxa (Hymenoptera: Apidae)
(2019-08-12)Two new species of the stingless bee genus Heterotrigona Schwarz (Apinae: Meliponini) are described and figured from Papua New Guinea: Heterotrigona (Sahulotrigona) tricholoma Engel, new species, lighter individuals of ... -
A new genus of augochlorine bees from northern Venezuela (Hymenoptera: Halictidae)
(2019-08-08)A new genus and species of the bee tribe Augochlorini (Halictinae) is described and figured from northern Venezuela. Trichommation osculans Engel, new genus and species, is a member of the Megaloptidia-group of genera as ... -
Morphological phylogeny of Megachilini and the evolution of leaf-cutter behavior in bees (Hymenoptera: Megachilidae)
(2019-07-03)A unique feature among bees is the ability of some species of Megachile Latreille s.l. to cut and process fresh leaves for nest construction. The presence of a razor between the female mandibular teeth (interdental laminae) ... -
Evolutionary Proteomics Reveals Distinct Patterns of Complexity and Divergence between Lepidopteran Sperm Morphs
(Oxford University Press (OUP), 2019-04-20)Spermatozoa are one of the most strikingly diverse animal cell types. One poorly understood example of this diversity is sperm heteromorphism, where males produce multiple distinct morphs of sperm in a single ejaculate. ... -
Climate Affects Plant-Soil Feedback of Native and Invasive Grasses: Negative Feedbacks in Stable but Not in Variable Environments
(Frontiers Media, 2019-11-05)The plant-soil feedback framework allows researchers to target the interaction of plants and root-associated microbes and to determine its interplay on plant-plant interactions. Plant-soil feedbacks in terrestrial ecology ... -
Distinct Contributions of Eroding and Depositional Profiles to Land-Atmosphere CO2 Exchange in Two Contrasting Forests
(Frontiers Media, 2019-03-13)Lateral movements of soil organic C (SOC) influence Earth's C budgets by transporting organic C across landscapes and by modifying soil-profile fluxes of CO2. We extended a previously presented model (Soil Organic C Erosion ... -
Adaptation to hummingbird pollination is associated with reduced diversification in Penstemon
(Wiley Open Access, 2019-08-02)A striking characteristic of the Western North American flora is the repeated evolution of hummingbird pollination from insect‐pollinated ancestors. This pattern has received extensive attention as an opportunity to study ... -
Beyond the black box: promoting mathematical collaborations for elucidating interactions in soil ecology
(Ecological Society of America, 2019-07-12)Understanding soil systems is critical because they form the structural and nutritional foundation for plants and thus every terrestrial habitat and agricultural system. In this paper, we encourage increased use of ... -
Ultraconserved element (UCE) probe set design: Base genome and initial design parameters critical for optimization
(Wiley Open Access, 2019-06-11)Targeted capture and enrichment approaches have proven effective for phylogenetic study. Ultraconserved elements (UCEs) in particular have exhibited great utility for phylogenomic analyses, with the software package phyluce ... -
Sensitivity to AMF species is greater in late‐successional than early‐successional native or nonnative grassland plants
(Ecological Society of America, 2019-07-30)Sensitivity of plant species to individual arbuscular mycorrhizal (AM) fungal species is of primary importance to understanding the role of AM fungal diversity and composition in plant ecology. Currently, we do not have a ... -
On population abundance and niche structure
(Wiley Open Access, 2019-03-04)Recent published evidence indicates a negative correlation between density of populations and the distance of their environments to a suitably defined ‘niche centroid’. This empirical observation lacks theoretical grounds. ... -
An evaluation of transferability of ecological niche models
(Wiley Open Access, 2018-08-18)Ecological niche modeling (ENM) is used widely to study species’ geographic distributions. ENM applications frequently involve transferring models calibrated with environmental data from one region to other regions or times ... -
A Phylogenomic Supertree of Birds
(MDPI, 2019-07-10)It has long been appreciated that analyses of genomic data (e.g., whole genome sequencing or sequence capture) have the potential to reveal the tree of life, but it remains challenging to move from sequence data to a clear ... -
Open access solutions for biodiversity journals: Do not replace one problem with another

Potential migratory routes of Urania boisduvalii (Lepidoptera: Uraniidae) among host plant populations
(Wiley Open Access, 2019-01-14)Aim Migratory species depend on various habitats and resources along their migration routes. Characteristics such as dependence on distinct habitats and the presence of multiple threats along their migratory routes make ... -
Large expert-curated database for benchmarking document similarity detection in biomedical literature search
(Oxford University Press (OUP), 2019-10-29)Document recommendation systems for locating relevant literature have mostly relied on methods developed a decade ago. This is largely due to the lack of a large offline gold-standard benchmark of relevant documents that ...
