Department of Agronomy and Horticulture: Faculty Publications
Crop residue removal may negatively affect soil mechanical properties, which are key components of soil quality. To evaluate potential long-term effects, we assessed the 10-yr impact of corn (Zea mays L.) residue removal (59 % of non-grain biomass annually) on surface soil mechanical properties (0–20 cm). We also evaluated whether adding carbon (C) amendments, such as using a winter rye (Secale cereale L.) cover crop or surface-applying cattle manure (24 Mg ha− 1 biannually) can ameliorate the effects of crop residue removal. This long-term study was under irrigated no-till continuous corn on a silt loam soil in south-central …

Increasing Temperatures Can Pose An Opportunity To Recover Endemic And Endangered Oriental Sweetgum Tree (Liquidambar Orientalis Mill.) From Extinction, Okan Ürker, Nurbahar Usta Baykal, Eren Ada
Turkish Journal of Botany
Evidence suggests that past climatic oscillations caused many species to drastically change their distribution range and had significant impacts on their survival capabilities. There is significant evidence suggesting that today's changing climate threatens many species to face a rapid extinction period in the coming decades and centuries. Understanding the changing range patterns provides significant input on biodiversity and conservation biology studies. However, warming climatic conditions may also present an opportunity for some species to expand their habitats?particularly those adapted to warmer environments. In this study, we asked how near-future climate change will affect the distribution range of the oriental sweetgum …

Is Climate Change Causing The Range Contraction Of Cape Rock-Jumpers (Chaetops Frenatus)?, Gregory D. Duckworth, Raquel A. Garcia, Rheinhardt Scholtz, Res Altwegg
Department of Agronomy and Horticulture: Faculty Publications
Species distribution models often suggest strong links between climate and species' distribution boundaries and project large distribution shifts in response to climate change. However, attributing distribution shifts to climate change requires more than correlative models. One idea is to examine correlates of the processes that cause distribution shifts, namely colonization and local extinction, by using dynamic occupancy models. The Cape Rock-jumper (Chaetops frenatus) has disappeared over most of its distribution where temperatures are the highest. We used dynamic occupancy models to analyse Cape Rock-jumper distribution with respect to climate (mean temperature and precipitation over the warmest annual quarter), …

Department of Agronomy and Horticulture: Faculty Publications
In 1665 Robert Hooke, looking at cork through his microscope, discovered that plants are composed of elementary structures he named “cells”. Variation in the expression of a single genome in a complex eukaryotic organism guides the initiation, maturation, physiology, and biochemistry of cells with different shapes and sizes, playing different structural and functional roles in space and time. How many kinds of cells—”cell types”— an organism possesses of course depends on the organism’s cellular complexity, but the plasticity within a cell type fuels the emergence of the concept of cell state (Figure 1). The transition between cell states is driven …
