“…A similar relationship was documented for Gambel's quail in the eastern plains of New Mexico (Raitt 1967). Gullion (1960) documented a similar correlation between Gambel's quail age ratios and summer rainfall in Nevada (r 2 ¼ 0.79). Scaled quail production and harvest were also correlated with summer rains (r 2 ¼ 0.64) in New Mexico (Campbell 1968).…”

A landscape-scale assessment of how bobwhite productivity varies in relation to weather does not exist for northern bobwhite (Colinus virginianus). We collected age and sex ratio and body mass data from hunter-harvested bobwhites in 16 counties of South Texas (n ¼ 72,797 bobwhites) during 2001-2009 hunting seasons. We evaluated annual bobwhite production (juvenile:adult age ratios) as a function of cumulative April-August rainfall using National Oceanic and Atmospheric Administration (NOAA) weather station data from Falfurrias and Hebbronville, Texas. We observed minimal among-year change in percent males harvested (51.0-54.5% male) and mean mass (156-160 g) of bobwhites across South Texas. We found no relationship between percent male or body mass and weather. We documented a positive, linear relationship between cumulative April-August rainfall and bobwhite age ratios (r 2 ¼ 0.94); we also documented a negative, linear relationship between summer (Jun-Aug) mean maximum daily temperature and bobwhite age ratios (r 2 ¼ 0.38). Our results suggest that rainfall is a landscape-scale indicator of annual bobwhite production in South Texas and can thus be used to manage annual expectations of quail hunters prior to the hunting season. ß 2012 The Wildlife Society.

Increasing L-ascorbic acid (AsA, vitamin C) content in fruits is a common goal in current breeding programs due to its beneficial effect on human health. Attempts to increase AsA content by genetic engineering have resulted in variable success likely due to AsA's complex regulation. Here, we report the effect of ectopically expressing in tomato the D-galacturonate reductase (FaGalUR) gene from strawberry, involved in AsA biosynthesis, either under the control of the constitutive 35S or the tomato fruit-specific polygalucturonase (PG) promoters. Although transgenic lines showed a moderate increase on AsA content, complex changes in metabolites were found in transgenic fruits. Metabolomic analyses of ripe fruits identified a decrease in citrate, glutamate, asparagine, glucose, and fructose, accompanied by an increase of sucrose, galactinol, and chlorogenic acid. Significant metabolic changes also occurred in leaves of 35S-FaGalUR lines, which showed higher non-photochemical fluorescence quenching (NPQ), indicative of a higher constitutive photo-protective capacity. Overall, overexpression of FaGalUR increased total antioxidant capacity in fruits and the results suggest a tight control of AsA content, probably linked to a complex regulation of cellular redox state and metabolic adjustment.

“…In areas with high humidity and fleshy plants, Gambel's quail may be able to exist without free water (Gullion 1960). In Nevada desert areas from mid-June to mid-July, water is an important factor limiting quail distribution (Gullion 1960). We found that quail use of catchments increased during the summer months, which may reflect a lack of succulent plants containing preformed water and increased need for water during dry, hot months.…”

Wildlife Use of Water Catchments in Southwestern Arizona

Construction of water developments has been used as a wildlife‐habitat improvement technique in desert environments since the 1940s. Use of water developments by wildlife has been described in anecdotal observations, through water‐hole counts, and with triggered still‐cameras, but few studies have directly quantified wildlife use. We used video surveillance equipment to document wildlife use of 3 water catchments located in the Sonoran Desert, southwestern Arizona, USA, from June 2000 to November 2003. For each visitation, we recorded time of day, season of use, and activities engaged in, and we correlated visits with temperature and relative humidity. We logged 37,989 observation hours and documented 34 species using the water catchments. Most of the species recorded visited water catchments year‐round with use peaking during June and July. The number of visits by nongame species (i.e., bats, raptors, mammalian predators, and rodents) exceeded the number of visits by game species (mule deer [Odocoileus hemionus], doves [Zenaida spp.], and Gambel's quail [Callipepla gambelii]). Visitation frequency for turkey vultures (Cathartes aura), owls, diurnal raptors, mule deer, coyotes (Canis latrans), and other mammalian predators increased with temperature. Most visits culminated in the animal drinking water. Other activities recorded were bathing, consumption of plant material and carrion, and intraspecies and interspecies interactions. We recorded 8 predation attempts: 4 by avian predators and 4 by bobcats (Lynx rufus). Although we documented that a number of species frequented water catchments, our observations do not prove need. However, we believe our observations do provide support for constructing water catchments that can accommodate a wide diversity of species.
