Environmentally adjusted productivity growth and shadow prices for dairy farms

Canadian Journal of Agricultural Economics/Revue canadienne d'agroeconomie, EarlyView.
Abstract We estimate the environmentally adjusted productivity growth and shadow price for Ontario dairy farms. We use an input‐oriented directional distance function and farm‐level data from 2000 to 2020. First, we find that while GHG emissions per cow increase with higher milk yields, emission intensity decreases as milk yield per cow increases.

Modeling ice cliff stability using a new Mohr–Coulomb-based phase field fracture model

Journal of Glaciology
Iceberg calving at glacier termini results in mass loss from ice sheets, but the associated fracture mechanics is often poorly represented using simplistic (empirical or elementary mechanics-based) failure criteria.

A Study of Time and Labour Use on Irish Suckler Beef Farms [PDF]

, 2006
End of project reportLabour is one of the four factors of production and an increasingly costly and scarce input on farms. The attractiveness of non-farming employment, the nature of farm work and the price received for farm outputs are resulting in ...

Perceived costs as drivers of wildlife management preferences in rural Tanzanian communities

Conservation Biology, EarlyView.
Abstract Effectively managing human–wildlife interactions is crucial for fostering coexistence on shared landscapes. Management options are most effective when aligned with the preferences of people directly affected by wildlife, yet little is known about how socioecological factors influence these preferences.

The association between herd- and cow-level factors and somatic cell count of Irish dairy cows [PDF]

, 2013
peer-reviewedSomatic cell count (SCC) is an indicator of both udder health and milk quality and is measured at an animal level through national milk recording schemes.

Felons’ chattels and English living standards in the later fourteenth and fifteenth centuries

The Economic History Review, EarlyView.
Abstract The later fourteenth and fifteenth centuries have long occupied an intriguing and contested place in discussions of England's long‐run economic development. One key issue around which debate has coalesced is the living standards of the population as a whole and of different groups within it. We contribute to this debate by bringing forward new

Silent pressure: Unveiling spinal lymphoma in horses and its parallels to other species

Equine Veterinary Education, EarlyView.
Summary Though the nervous system is an uncommon location for lymphoma, the disease should remain a differential diagnosis in some cases of ataxia in equids. Diagnosis of lymphoma can be challenging, although a combination of cytology, histopathology and immunophenotyping can aid in definitive diagnosis and therefore more accurately guide treatment and

Stayability in the Era of Early‐Challenged Females: Genetic Parameters and Correlations With Economically Relevant Traits

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT This study aimed to estimate the variance components, heritabilities and genetic correlations between four new different categories of stayability (STAY48‐2, STAY48‐3, STAY54‐2, STAY54‐3) with weight at 240 days of age (W240), weight at 450 days of age (W450), scrotal circumference at 365 days of age (SC365), age at puberty in males (APM ...

47 Years of Large Antarctic Calving Events: Insights From Extreme Value Theory

Geophysical Research Letters
Massive calving events result in significant instantaneous ice loss from Antarctica. The rarity and stochastic nature of these extreme events makes it difficult to understand their physical drivers, temporal trends, and future likelihood. To address this
