Ground‐based robotic remote sensing for standardized biodiversity monitoring in coastal habitats

Remote Sensing in Ecology and Conservation, EarlyView.
Illustrated workflow of the proposed citizen‐to‐robot monitoring pipeline: (i) expert‐validated citizen observations are translated into AI models, (ii) deployed on a ground‐based robotic platform for proximal sensing of coastal dune habitats, (iii) enabling standardized detection of ecological targets (e.g., Pancratium maritimum & Brithys crini), and (

Environmental Stress Effects on Vigor, Mortality, and Growth in Northern Hardwood Forests Along a Pollution-Climate Gradient [PDF]

, 1998
Concern exists over the effects of interacting environmental stresses on the ecological integrity of temperate forests. Coincidence of sensitivity to drought, increasing occurrence of defoliation, and elevated pollutant deposition has produced ...

Cotton Farming Pesticides Affect Ileal Microbiota Activity and Expression of Virulome but Not Resistome or Metabolic Pathways in a Sedentary Wild Passerine

Environmental Toxicology, EarlyView.
ABSTRACT The increased use of agrochemicals to enhance crop production has had detrimental environmental effects including implication in the sharp decline of North American farmland‐breeding birds. Here, using a combination of deep shotgun metatranscriptomics and pesticide exposure data, we sought to assess whether exposure to cotton (Gossypium spp ...

Critical impact of defoliation on garlic yield during key developmental stages [PDF]

Pesquisa Agropecuária Brasileira
The objective of this work was to evaluate the effect of defoliation levels at different growth stages of garlic plants on total and marketable yields. The experiments were conducted during two crop seasons, when five dates (30, 60, 90, 110, and 130 days

Leaf defoliation and Tabernaemontana rotensis (Asterids: Gentianales: Apocynaceae) flower induction and fruit development

Journal of Threatened Taxa, 2023
Tabernaemontana rotensis (Kaneh.) P.T. Li is an attractive small tree that is endemic to the islands of Guam and Rota. Conservation efforts of the threatened population are constrained by lack of research.

Fruit quality and production of Vitis vinifera L. Chardonnay affected by partial defoliation in tropical highlands [PDF]

, 2015
Using a completely randomized design with twotreatments (50% defoliation and a control without defoliation)and six replications per treatment, the fruit quality and productionof grape plants subjected to early partial-defoliation in Villa deLeyva ...

Goose herbivory alters soil microbial community functional potential in a sub‐Arctic wetland

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Herbivory alters below‐ground resource dynamics via direct and indirect mechanisms, yet its effects on microbial functional potential remain poorly understood. This limits our understanding of the mechanisms that link animal, plant and microbial functional roles in ...

The Coloniality of Data: Police Databases and the Rationalization of Surveillance from Colonial Vietnam to the Modern Carceral State

The British Journal of Sociology, EarlyView.
ABSTRACT Tracing the early adoption of computer gang databases by the Los Angeles County Sheriff's Department and the Los Angeles Police Department in the 1980s to the deployment of computationally‐assisted surveillance during the Vietnam War, this paper uses a genealogical approach to compare surveillance technologies developed across the arc of ...

Offspring performance does not explain oviposition preference in the leafminer Stigmella sorbi (Lepidoptera: Nepticulidae): a tri‐trophic perspective

Insect Science, EarlyView.
We studied oviposition site selection in a leaf‐mining moth (Stigmella sorbi) on rowan trees (Sorbus aucuparia) in northwestern Russia, assessing larval performance across different shoot types, leaf positions, and leaflets. Larval survival was highest on long vegetative shoots, yet females showed no preference for these optimal sites.

Forest defoliation scenarios

Mathematical Biosciences and Engineering, 2007
We consider the mathematical model originally created by Ludwig, Jones, and Holling to model the infestation of spruce forests in New Brunswick by the spruce budworm. With biologically plausible parameter values, the dimensionless version of the model contains small parameters derived from the time scales of the state variables and smaller parameters ...
