Infection Models for Pine Wilt Disease on the Basis of Vector Behaviors

open access: yesPopulation Ecology, EarlyView.
Infection models for pine wilt disease without vector density were built to estimate the transmission coefficient of the pathogenic nematode. The models successfully simulated the annual change in the density of infected trees for four pine stands. ABSTRACT Pine wilt disease is caused by the pinewood nematode (Bursaphelenchus xylophilus Steiner et ...

Response Essay: Some Observations on Professor Schwartz\u27s Foundation Theory of Evidence [PDF]

open access: yes, 2012
Professor David Schwartz\u27s A Foundation Theory of Evidence posits an intriguing new way to look at Evidence. It asserts that offered evidence must meet a tripartite requirement before it can be relevant. The tripartite requirement is that the evidence

Níveis de treonina digestível em dietas para fêmeas suínas de alto potencial genético em lactação sob condições de alta temperatura ambiente Digestible threonine levels of high-producing lactating sows maintained under high temperature environment conditions

open access: yesRevista Brasileira de Zootecnia, 2007
Foram utilizadas 52 fêmeas suínas em lactação distribuídas em delineamento experimental de blocos ao acaso, composto de quatro níveis de treonina digestível (0,64; 0,67; 0,70 e 0,73%) na dieta e 13 repetições, em que cada unidade experimental foi ...

Estimation of Evapotranspiration from the People’s Victory Irrigation District Based on the Data Mining Sharpener Model

open access: yesAgronomy, 2023
Reasonable evaluation of evapotranspiration (ET) is crucial for optimizing agricultural water resource management. In the study, we utilized the Data Mining Sharpener (DMS) model; the Landsat thermal infrared images were sharpened from a spatial ...

An Adaptive Management Model for Brown Bears in Hokkaido: Based on Total Population and the Number of Nuisance Bears

open access: yesPopulation Ecology, EarlyView.
Bear management changes management actions according to the horizontal axis of the population size and the vertical axis of the number of nuisance bears. Aiming for the target population size of Ntar, Actions I and II protect the bears, and Action IV reduces the population.

Working Capital Requirement and the Unemployment Volatility Puzzle

open access: yes, 2015
Shimer (2005) argues that a search and matching model of the labor market in which wage is determined by Nash bargaining cannot generate the observed volatility in unemployment and vacancy in response to reasonable labor productivity shocks.

Speciation Through the Lens of Population Dynamics: A Theoretical Primer on How Small and Large Populations Diverge

open access: yesPopulation Ecology, EarlyView.
Population size and dynamics fundamentally shape speciation by influencing genetic drift, founder events, and adaptive potential. Small populations may speciate rapidly due to stronger drift, whereas large populations harbor more genetic diversity, which can alter divergence trajectories. We highlight theoretical models that incorporate population size
