Wild Animal Suffering Is Not Intractable: A Precautionary Approach to Compassionate Intervention

Journal of Applied Philosophy, EarlyView.
ABSTRACT Wild animals suffer due to human activity, yet natural factors contribute far more significantly to their suffering. In light of this, some propose that we have a pro tanto obligation to intervene in ecosystems to improve wild animal welfare.

Identification of an innexin required for termination of the asexual state in planarian reproductive switching.

PLoS Genetics
Many metazoans switch between asexual and sexual reproduction based on environmental changes, life cycle phases, or both. This reproductive strategy enables them to benefit from the features of both reproductive modes. In general, asexual reproduction is

Rethinking False Spring Risk [PDF]

Temperate plants are at risk of being exposed to late spring freezes. These freeze events - often called false springs - are one of the strongest factors determining temperate plants species range limits and can impose high ecological and economic damage.

Borax Promotes Fertility of Brassica napus Better Than Other Boron Species at Suboptimal Supply

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Continuous and sufficient boron (B) supply is essential for achieving maximum yield in Brassica napus. Increasing incidences of environmental water limitation are linked to reduced plant B availability and increased B deficiencies.

Vegetative tissue lectins of peanut (A. hypogaea).

Indian journal of biochemistry & biophysics, 1997
Lectin activities in roots, nodules, stems and leaves of 1-6 week old peanut plant (A. hypogaea) were checked by erythrocyte (human and rabbit) agglutination and sugar inhibition assays. Human and rabbit erythrocyte agglutinating activities were specifically inhibited by lactose/cellobiose (SLII) and methyl alpha-mannoside (SLI) respectively.

Growth response to temperature of two maize (Zea mays L.) hybrids with differing levels of cold tolerance : a thesis presented in partial fulfillment of the requirements for the degree of Master of Agricultural Science in Plant Science (Seed Technology), Massey University [PDF]

, 1993
Low temperatures are a hazard to maize production especially in high altitude and high latitude areas (Eagles, 1979; Hardacre and Eagles, 1986) where it may cause substantial yield reductions through its accumulated effect on vegetative and reprodutive ...

Effect of Vapor Pressure Deficit on Nutrient Uptake and Growth of Four Tomato Varieties Grown Hydroponically at Low Nutrient Concentrations

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Marginal water sources, such as wastewater, have been proposed as the basis for hydroponic nutrient solutions to improve the resource efficiency of greenhouse‐based tomato production. Such water sources are often low in plant‐available nutrient concentrations, and uptake and use efficiency of these nutrients may vary widely among ...

Characterization of Expressed Genes Isolated From Oil Palm Vegetative, Normal and Abnormal Inflorescence Meristems Using EST Approach [PDF]

, 2003
Little is known about the function of genes expressed in oil palm vegetative meristem tissues, which are expressed during transition from vegetative to reproductive growth, and those expressed during the formation of abnormal inflorescence. This study
