The causal effect of agricultural landscape simplification on Germany's grasslands during a compound drought and heatwave in 2018

American Journal of Agricultural Economics, EarlyView.
Abstract Preserving ecosystem services, along with economic and environmental benefits, will require future landscape policies to identify and incorporate relevant landscape features. In this paper, we investigate the causal effect of agricultural landscape simplification on drought‐related grassland damages.

Investigating the Effects of Optimized Mineral Fertilization on Plant Growth, Physiological Traits, Tuber Yield, and Biochemical Contents of Potato Crop

Horticulturae
Plants of two potato (Solanum tuberosum L.) varieties ‘Spunta’ (mid-early maturity) and ‘Kensa’ (mid-late maturity) were subjected to three nitrogen (N), phosphorus (P), and potassium (K) fertilization regimes, with T1 optimal rates (as recommended by ...

Palatability of geophyte underground storage organs partially explains their depth in the Cape Floristic Region, geophyte capital of the world

American Journal of Botany, EarlyView.
Abstract Premise The soil depth of underground storage organs (USOs) of geophytes involves cost–benefit trade‐offs and may relate to USO age, size, and disturbances such as fire and herbivory. Yet determinants of USO depth are poorly studied. We posit that belowground mammalian predation of USOs is a selective force for the positive relationship ...

Impact of Plant Density on the Formation of Potato Mimitubers Derived from Microtubers and Tip-Cuttings in Plastic Houses

Journal of Integrative Agriculture, 2013
The potato minitubers have been widely used for the elite seed propagation to improve the seed potato system in China. However, little information is available for an efficient production of the minitubers with high plant density in the protected growing

Influence of Molecular Genetic Classes on Behavior in Prader‐Willi Syndrome

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT A wide range of behavioral phenotypes has been described in PWS patients including autism spectrum disorder (ASD). The prevalence of behavioral disorders was studied in 292 participants over 3 years with genetically confirmed PWS (N = 164 females and N = 128 males) with deletion (N = 182) and mUPD (maternal uniparental disomy) (N = 99).

Differences in predominant collagen fiber orientation between dorsal and plantar trabecular bone tracts of adult mule deer calcanei suggest strain‐mode‐specific adaptation

The Anatomical Record, EarlyView.
Polarized microscopic images of the outer bone cortex (a and b) and deeper trabecular bone (c and d) of the deer calcaneus in thin cross‐sections. The brighter gray levels reflect more oblique‐to‐transverse collagen fibers in the compression/dorsal bone (a, c) and the darker gray levels reflect more longitudinal collagen in the tension/plantar bone (b,

Potato Tuberworm Phthorimaea operculella (Zeller) (Lepidoptera: Gelechioidea) Leaf Infestation Affects Performance of Conspecific Larvae on Harvested Tubers by Inducing Chemical Defenses

Insects, 2020
Conspecific aboveground and belowground herbivores can interact with each other, mediated by plant secondary chemicals; however, little attention has been paid to the interaction between leaf feeders and tuber-feeders.

EFFECT OF SOME ORGANIC FERTILIZATION SOURCES AND MICRONUTRIENTS APPLICATION METHODS ON YIELD AND QUALITY OF POTATO (Solanum tuberosum, L.) [PDF]

Journal of Plant Production, 2007
Two field trials were conducted on potato plants cv. Spunta, in the vegetable private farm at Kafr Meet Faris, Dakahlia Governorate, during 2004/2005 and 2005/2006 seasons to study  the effect of some organic fertilization sources, either single and/or ...

A second species of non‐crocodyliform crocodylomorph from the Late Triassic fissure deposits of southwestern UK: Implications for locomotory ecological diversity in Saltoposuchidae

The Anatomical Record, EarlyView.
Abstract The Late Triassic–Early Jurassic fissures of the Bristol Channel area (southwest England and south Wales) are renowned for their diverse vertebrate faunas. These assemblages have yielded an array of predominantly small‐bodied forms that are crucial to our understanding of the early evolution of several major tetrapod clades.

Effects of commercial organic fertilizers on the yield and yield structure of potato cultivars [PDF]

Selekcija i Semenarstvo, 2012
The research work has dealt with investigations of two type commercial organic fertilizers (DCM ECO-MIX 4 NPK 7:7:10 i GUANITO NPK 6:15:3) effects on the yield and yield structure of three potato cultivars (Cleopatra, Carrera and Sylvana).
