Spatial Survival Model for COVID-19 in México.

A spatial survival analysis was performed to identify some of the factors that influence the survival of patients with COVID-19 in the states of Guerrero, México, and Chihuahua. The data that we analyzed correspond to the period from 28 February 2020 to 24 November 2021. A Cox proportional hazards frailty model and a Cox proportional hazards model were fitted.

Evidence of Infection and Associated Thermal Signatures in Southern Highbush Blueberry ( Interspecific Hybrids).

, a gram-negative bacterium vectored to plants via feeding of infected insects, causes a number of notorious plant diseases throughout the world, such as Pierce's disease (grapes), olive quick decline syndrome, and coffee leaf scorch. Detection of in infected plants can be challenging because the early foliar disease symptoms are subtle and may be attributed to multiple minor physiological stresses and/or borderline nutrient deficiencies. Furthermore, may reside within an infected plant for one or more growing seasons before traditional visible diagnostic disease symptoms emerge.

Doru luteipes (Dermaptera: Forficulidae) and Orius insidiosus (Hemiptera: Anthocoridae) as Nocturnal and Diurnal Predators of Thrips.

Thrips (Thysanoptera, Thripidae) are pests of several crops and their chemical control is mainly hindered by their thigmotactic habits, which in turn allows the use of biological control agents with similar habits. Orius (Hemiptera: Anthocoridae) are effective control agents for thrips and are commercialized in many countries. Habitat overlap exists between Doru luteipes (Scudder) (Dermaptera: Forficulidae) and thrips, making D.

A Bayesian Prediction Spatial Model for Confirmed Dengue Cases in the State of Chiapas, Mexico.

Dengue is one of the major health problems in the state of Chiapas. Consequently, spatial information on the distribution of the disease can optimize directed control strategies. Therefore, this study aimed to develop and validate a simple Bayesian prediction spatial model for the state of Chiapas, Mexico.

Plant Pathogen Invasion Modifies the Eco-Evolutionary Host Plant Interactions of an Endangered Checkerspot Butterfly.

New plant pathogen invasions typified by cryptic disease symptoms or those appearing sporadically in time and patchily in space, might go largely unnoticed and not taken seriously by ecologists. We present evidence that the recent invasion of (Dermateaceae) into the Pacific Northwest USA, which causes foliar necrosis in the fall and winter on (plantain), the primary (non-native) foodplant for six of the eight extant Taylor's checkerspot butterfly populations (, endangered species), has altered eco-evolutionary foodplant interactions to a degree that threatens butterfly populations with extinction. Patterns of butterfly, larval food plant, and disease development suggested the ancestral relationship was a two-foodplant system, with perennial spp.
