Petiole length in Boerhavia (Nyctaginaceae) approximates the golden ratio phi

Autor: Rothschild,Walter Jordan,Karl, Justin K Williams

Publikováno v: Journal of the Botanical Research Institute of Texas. 12:667-682

The leaves of Boerhavia exhibit anisophylly. It is here hypothesized that the scale of the uneven leaves exhibits a determined pattern, rather than an arbitrary difference in size. To test for this, the opposite petioles of Boerhavia diffusa and B. e

Host Cues Mediate Growth and Establishment of Oak Mistletoe (Phoradendron leucarpum, Viscaceae), an Aerial Parasitic Plant

Autor: Michelle L. Lewis, Timothy J. Verastegui, Amber L. Faust, Brandi C. Cannon, James Sopas, Sara E. Cabrera, Justin K. Williams, Christopher P. Randle, Stephen Lee, Angela K. Hawkins, Amy A. Perez

Publikováno v: Castanea. 83:249-262

The oak mistletoe (Phoradendron leucarpum, Viscaceae) is well-documented to exhibit preference for a few potential host species in a given locality, even when many potential host species are present. In trying to explain this distribution, we examine

Analysis of the modern distribution of South African Gerbilliscus (Rodentia: Gerbillinae) with implications for Plio-Pleistocene palaeoenvironmental reconstruction

Autor: Timothy Lee Campbell, Patrick J. Lewis, Justin K. Williams

Publikováno v: South African Journal of Science, Vol 107, Iss 1/2 (2011)

There are four extant species of Gerbilliscus, formally classified as Tatera, native to the southern African subregion, each exhibiting varying degrees of environmental tolerance. These species are also routinely reported from many of the palaeontolo

A Geographic Information Systems (GIS)-based analysis of modern South African rodent distributions, habitat use, and environmental tolerances

Autor: Justin K. Williams, Monte L. Thies, Patrick J. Lewis, Timothy L. Campbell

Publikováno v: Ecology and Evolution

Goals of this study were to: (1) develop distributional maps of modern rodent genera throughout the countries of South Africa, Lesotho, and Swaziland by georeferencing museum specimens; (2) assess habitat preferences for genera by cross-referencing l

The Status ofFraxinus papillosa(Oleaceae): Sem Study of Epidermal Features

Autor: Guy L. Nesom, Justin K. Williams

Publikováno v: Lundellia. 13:14-22

The abaxial leaf surfaces of Fraxinus in the southwestern USA and northwestern Mexico are sometimes white-glaucous and have been described as “papillose.” Individuals exhibiting this morphology have been identified as F. papillosa, a species repo

Autor: David J. Middleton, Mary E. Endress, Tatyana Livshultz, Justin K. Williams

Publikováno v: Annals of the Missouri Botanical Garden. 94:324-359

Phylogenetic relationships were reconstructed among 59 of 77 genera of subfamily Apocynoideae and exemplars of Periplocoideae, Secamonoideae, and Asclepiadoideae (collectively the APSA clade) using sequences from four regions of the chloroplast genom

Species-Area Relationships Indicate Large-Scale Data Gaps in Herbarium Collections

Autor: Justin K. Williams, William L. Lutterschmidt

Publikováno v: Lundellia. 9:41-50

Species-area relationships (SAR) are useful in predicting species richness for a given geographical area. Using SAR and the state of Texas as a case study, we present a model that provides a quantifiable and objective approach for identifying large s
