Reducing Protected Lands In A Hotspot Of Bee Biodiversity: Bees Of Grand Staircase-Escalante National Monument, Joseph S. Wilson, Matt Kelly, Olivia Messinger Carril Dec 2018

Reducing Protected Lands In A Hotspot Of Bee Biodiversity: Bees Of Grand Staircase-Escalante National Monument, Joseph S. Wilson, Matt Kelly, Olivia Messinger Carril

Biology Faculty Publications

Grand Staircase-Escalante National Monument is a federally protected area found in central southern Utah. Designated in 1996 by President William J. Clinton, it was recently reduced in size by President Donald J. Trump in a proclamation that turned the one large monument into three smaller ones. A long-term, standardized study of the bees had been conducted from 2000–2003, revealing 660 species. The bee communities of the area are characterized by being spatially heterogeneous; most of the bees occur in isolated areas, with only a few being both abundant and widespread. Here we examine what affect the recent resizing of the …

A significant body of evidence has demonstrated that biodiversity stabilizes ecosystem functioning over time in grassland ecosystems. However, the relative importance of different facets of biodiversity underlying the diversity–stability relationship remains unclear. Here we used data from 39 biodiversity experiments and structural equation modeling to investigate the roles of species richness, phylogenetic diversity, and both the diversity and community-weighted mean of functional traits representing the ‘fast–slow’ leaf economics spectrum in driving the diversity–stability relationship. We found that high species richness and phylogenetic diversity stabilize biomass production via enhanced asynchrony. Contrary to our hypothesis, low phylogenetic diversity also enhances ecosystem stability …


Prioritizing Phylogenetic Diversity Captures Functional Diversity Unreliably, Florent Mazel, Matthew W. Pennell, Marc W. Cadotte, Sandra Diaz, Giulio Valentino Dalla Riva, Richard Grenyer, Fabien Leprieur, Arne O. Mooers, David Mouillot, Caroline M. Tucker, William D. Pearse Jul 2018

In the face of the biodiversity crisis, it is argued that we should prioritize species in order to capture high functional diversity (FD). Because species traits often reflect shared evolutionary history, many researchers have assumed that maximizing phylogenetic diversity (PD) should indirectly capture FD, a hypothesis that we name the “phylogenetic gambit”. Here, we empirically test this gambit using data on ecologically relevant traits from >15,000 vertebrate species. Specifically, we estimate a measure of surrogacy of PD for FD. We find that maximizing PD results in an average gain of 18% of FD relative to random choice. However, this average …


Aquatic Polyphaga (Insecta: Coleoptera) From Kampong Speu Province, Cambodia, Hendrik Freitag, Bros Doeurk, Soksan Chhorn, Chandara Khin, Sopha Sin, Sarah Ehlers, Jody Voges, Jhoana Garces, Sophany Phauk Jan 2018

Aquatic Polyphaga (Insecta: Coleoptera) From Kampong Speu Province, Cambodia, Hendrik Freitag, Bros Doeurk, Soksan Chhorn, Chandara Khin, Sopha Sin, Sarah Ehlers, Jody Voges, Jhoana Garces, Sophany Phauk

We present the results of a faunistic inventory undertaken on aquatic Polyphaga beetles as part of a workshop organised by the BIO-PHIL project in Cambodia. Three small rivers and a pond in Kampong Speu Province were sampled in July 2018. Twenty-one taxa were collected during the sampling and identifi ed to species or morphospecies level. These are described with comments on habitat, distribution and further remarks, where applicable. A checklist of the genera and species of aquatic Dryopidae, Elmidae, Hydraenidae, Hydrophilidae, Psephenidae and Spercheidae of Cambodia is presented which includes new records for the country


Three New Species Of Grouvellinus Champion, 1923 From Maliau Basin, Sabah, Borneo, Discovered By Citizen Scientists During The First Taxon Expedition (Insecta, Coleoptera, Elmidae), Hendrik Freitag, Iva Njunjic, Clister V. Pangantihon Jan 2018

Three New Species Of Grouvellinus Champion, 1923 From Maliau Basin, Sabah, Borneo, Discovered By Citizen Scientists During The First Taxon Expedition (Insecta, Coleoptera, Elmidae), Hendrik Freitag, Iva Njunjic, Clister V. Pangantihon

Further results are presented of the first field course at Maliau Basin, Malaysian Borneo organized by Taxon Expeditions, an organization which enables citizen scientists to be directly involved in taxonomic discoveries. Three new species of the aquatic beetle genus Grouvellinus Champion, 1923, namely G. leonardodicaprioi sp. n., G. andrekuipersi sp. n., and G. quest sp. n. were collected jointly by the citizen scientists and taxonomists during the fieldwork in Maliau Basin. Material was mainly sampled from sandstone bottom rocks of blackwater streams at altitudes between 900 m and 1,000 m using fine-meshed hand-nets. The genus is widely distributed …


Sparsorythus Sescarorum, New Species From Mindoro, Philippines (Ephemeroptera, Tricorythidae), Jhoana Garces, Ernst Bauernfeind, Hendrik Freitag Jan 2018

Sparsorythus Sescarorum, New Species From Mindoro, Philippines (Ephemeroptera, Tricorythidae), Jhoana Garces, Ernst Bauernfeind, Hendrik Freitag

Biology Faculty Publications

A new mayfly species, Sparsorythus sescarorum sp. n. (Tricorythidae) is described from Mindoro Island, Philippines. Nymphs are characterized by the combination of the following characters: compound eyes of approximately equal size in both sexes, shape and setation of legs, presence of rudimentary gills on abdominal segment VII, and some details of mouthparts. Male imagines are characterized by the coloration pattern of wings and details of genitalia. The developmental stages are matched by DNA barcodes.
