Uncovering renewable energy policy impact channels on land values, the local farm structure, and farmland heterogeneity

American Journal of Agricultural Economics, EarlyView.
Abstract Germany's Renewable Energy Sources Act (REA), enacted in 2000 and subsequently amended, subsidized national renewable energy production with fixed feed‐in tariffs for renewable energy sources (RE) from wind, solar, and biogas. Empirical studies suggest that the policy was creating windfall effects for landowners and attribute farmland use ...

Fructan biosynthesis gene expression upon cold acclimation in orchardgrass (Dactylis glomerata L.)

Grassland Research
Background Fructan content and flux in temperate forages can benefit the grasses through increased cold hardiness, increased drought tolerance, and improved forage quality.

An ecological study of a chionochloa population : a thesis presented in partial fulfilment of the requirements for the degree of Master of Agricultural Science at Massey University of Manawatu [PDF]

, 1966
The Chionochloa community under study occupies approximately 63 acres on the summit of Mt Kaiparoro (2,660 ft a.s.l.), a large ridge situated about four miles east of the main northern Tararua Range and separated from it by the headwaters of the ...

Evaluating the African arid corridor hypothesis: A meta‐analysis including the phylogenetic and biogeographical history of Sesamothamnus

American Journal of Botany, EarlyView.
Abstract Premise We examined the African arid corridor (AAC) disjunction pattern of vascular plants between northeastern and southwestern Africa in the context of geological and climatic events since the late Miocene. We developed a phylogenetic and biogeographical framework for the arid‐adapted genus Sesamothamnus (Pedaliaceae), a classic example of ...

Selection of meadow fescue for persistence under frequent defoliation

Grassland Research
Background Meadow fescue (Schedonorus pratensis (Huds.) P. Beauv.) is a reemerging pasture grass for temperate regions of North America. One disadvantage of this species is its lack of tolerance to frequent defoliation at low residual sward heights. This

Climate and seed mass drive intraspecific variation in seed longevity in storage

American Journal of Botany, EarlyView.
Abstract Premise Conservation seed banks are essential for ex situ plant conservation, but stored seeds slowly deteriorate and lose viability. Seed longevity in storage is determined by the initial seed viability and the rate of seed viability loss. The rate of seed viability loss in storage varies between species and possibly between populations or ...

Overview of autotoxicity in alfalfa (Medicago sativa L.): Identifying gaps between laboratory findings and demonstration at field scale

Grassland Research
Autotoxicity is a type of intraspecific allelopathy in which compounds released by a plant inhibit the growth of other plants of the same species. In alfalfa (Medicago sativa L.), an herbaceous perennial legume widely used in hay and pasture production ...

Origin, evolution and biogeographic dynamics of the European rabbit (Oryctolagus cuniculus) in Southwestern Europe

The Anatomical Record, EarlyView.
Abstract The Pleistocene is a key period for understanding the evolutionary history and palaeobiogeography of the European rabbit (Oryctolagus cuniculus). The species was first documented in southeastern Iberia at the beginning of the Middle Pleistocene and appears to have rapidly spread throughout Southwestern Europe, where it was found in numerous ...

Narrow‐leaved plantain (Plantago lanceolata L.): A review of research on forage management within temperate grazing systems

Grassland Research
Forage plantain (Plantago lanceolata L.) has emerged as a valuable agronomic species within grazing systems in New Zealand. The release of two cultivars in New Zealand in the mid‐1990s led to on‐farm use and research.

Morphological variation in atlas and axis of Neotropical spiny rats (Rodentia, Echimyidae)

The Anatomical Record, EarlyView.
Abstract The unique morphologies of the first two cervical vertebrae, the atlas and axis, represent a significant innovation in mammalian evolution. These structures support the weight of the head and enable intricate movements of the head and neck.
