Background Patch-burn management approaches attempt to increase overall landscape biodiversity by creating a mosaic of habitats using a patchy application of fire and grazing. We tested two assumptions of the patch-burn approach, namely that: (1) fir

Latitudinal trends in genus richness of vascular plants in the Eocene and Oligocene of North America

The latitudinal richness gradient is a frequent topic of study on the modern landscape, but its history in deep time is much less well known. Here, we preliminarily evaluated the paleolatitudinal richness gradient of vascular plants for the Eocene (5

The Effects of Removal of Juniperus virginiana L. Trees and Litter from a Central Oklahoma Grassland

We studied species composition after Juniperus virginiana tree and litter removal in a central Oklahoma grassland. Tree removal had the most significant effect on stems per quadrat and vegetation cover. Litter removal effects were not as strong. Howe

Variation in individual density may explain the unimodal richness-biomass relationship in which species richness peaks at an intermediate level of total biomass. However, it is unclear how individual density is regulated by community thinning (i.e.,

A bibliography of 85 references involving Oklahoma flora is provided, 52 of which provide a vascular plant species list from an unambiguous area. I list geographic, topographic, and taxonomic summary data for 59 floras (some references provide multip

Along the prairie/forest transition zone oak savannas have been severely degraded by logging, clearing for agriculture, fire suppression, invasion of exotic plants, and excessive livestock grazing. Savanna shares equal billing with tallgrass prairie

We present novel rearing records of Agromyzidae (Diptera) from throughout the United States. We describe leaf mines or other larval habits for 27 species, plus five others whose identification is tentative, and another five that are identified only t

Scouring-rushes (Equisetum sg. Hippochaete) are a group of horsetails with perennial aerial shoots strongly encrusted in silica. Accordingly, they seem to resist attacks from most herbivorous insects. Michelsen (2008) speculated that larval developme

We studied trophic resource use and availability in three populations of the common frog (Rana temporaria): one from the subarctic (Kilpisjarvi, Finland), and two (alpine and low-altitude valley populations) from the Retezat Mountains (Southern Carpa

Fossil plants are often used to infer the paleoclimates in which they occurred by applying methods that match fossils to their nearest living relatives and, in turn, use the climatic preferences of the living species to infer paleoclimate. These meth
