The impact of a native, leaf-feeding chrysomelid beetle (Phaedon sp. nr. oviformis) on bittercress (Cardamine cordifolia: Cruciferae), was evaluated in an exclusion experiment. Multivariate statistical analysis showed a significant increase in plant performance in the rotenone exclusion compared to performance in the paired control treatment. Plant response to the reduction of herbivory was a c...
Two interrelated problems in biology are understanding the regulatory logic and predictability of morphological evolution. Here, we studied these problems by comparing Arabidopsis thaliana, which has simple leaves, and its relative, Cardamine hirsuta, which has dissected leaves comprising leaflets. By transferring genes between the two species, we provide evidence for an inverse relationship be...
Phylogenetic relationships within the tribe Moriomorphini Sloane, 1890 are analyzed cladistically based on 75 morphological characters and 21 ingroup terminal taxa rooted at a Trechus obtusus Erichson outgroup. Based on the resultant cladistic relationships, two subtribes-Moriomorphina and Amblytelina Blackburn, 1892-are recognized, with the following new synonymies proposed: Meonides Sloane, 1...
Recent advances in oil-palm breeding and agronomic practices may have influenced the dry-matter production nutrient demand of tenera oil palm since last comprehensive studies published some three decades ago. This has raised concerns, updated knowledge requirements at various stages growth is essential for formulating fertilizer recommendations that meet agronomic, economic, environmental objec...
The southern Neotropical genus Anahi Martínez is comprehensively revised and now includes three species: A. dentata Ocampo Ruiz-Manzanos new species, A. guaraniticus Martínez, and A. oblivia Ocampo Ruiz-Manzanos new species. The new species extend the distribution of the genus from Paraguay and Bolivia to Argentina. A. guaraniticus is redescribed and the characters that define the genus are ext...
A conserved genetic toolkit underlies the development of diverse floral forms among angiosperms. However, the degree of conservation vs divergence in the configuration of these gene regulatory networks is less clear. We addressed this question in a parallel genetic study between the closely related species Arabidopsis thaliana and Cardamine hirsuta. We identified leafy (lfy) and apetala1 (ap1) ...
Type II InP/GaAsSb transistors have attracted much interest in high speed microelectronics. However, Kirk-effectinduced current blocking was observed, limiting the highest achievable current density and hence the speed. In this work, we present an explanation as to the cause of current blocking in InP/GaAsSb DHBTs. The effects of collector thickness are investigated and methods to achieve highe...
