Predictive Models for Characterization of Ecological Data [PDF]
arXiv, 2005 Although ARTMAP and ART-based models were introduced in early 70's they were not used in characterizing and classifying ecological observations. ART-based models have been extensively used for classification models based on satellite imagery. This report, to our knowledge, is the first application of ART-based methods and specifically ARTMAP for ...

Journal of Microbiology and Biotechnology, 2015 Ever since the ban on antibiotic growth promoters (AGPs), the livestock death rate has increased owing to pathogenic bacterial infections. There is a need of developing AGP alternatives; however, the mechanisms by which AGP enhances livestock growth ...

Advanced Science, EarlyView.In this study, variation and genetic basis of ionome among Tartary buckwheat population are investigated, illuminating their significance in the domestication and diversification of Tartary buckwheat. And three genes (FtACA13 for Na content, FtYPQ1 for Zn content, FtNHX2 for As content) are identified with the dominant haplotypes and functional ...

$C_{E}PT$ Symmetry of the Simple Ecological Dynamical Equations [PDF]
arXiv, 2005 It is shown that all simple ecological, i.e. population dynamical equations (unlimited exponential population growth (or decrease) dynamics, logistic or Verhulst equation, usual and generalized Lotka-Volterra equations) hold a symmetry, called $C_{E}PT$ symmetry.

Primary ecological succession in vascular epiphytes: The species accumulation model
, 2017 Epiphytes are integral to tropical forests yet little is understood about how succession proceeds in these communities. As trees increase in size they create microhabitats for late‐colonizing species in both small and large branches while maintaining ...

Ecological succession of a Jurassic shallow-water ichthyosaur fall
Nature Communications, 2014 After the discovery of whale fall communities in modern oceans, it has been hypothesized that during the Mesozoic the carcasses of marine reptiles created similar habitats supporting long-lived and specialized animal communities.

Advanced Science, EarlyView.In CLas‐infected D. citri, CLas lowers 20E levels initially, relieving the suppression of ETH release. The subsequent increase in ETH levels upregulates its receptor DcETHR and activates the JH signaling pathway. The signaling cascade of 20E‐ETH/ETHR‐JH along with miR‐210, targeting DcETHR, boost female fecundity in CLas+ D.

American Journal of Community Psychology, Volume 70, Issue 3-4, Page 340-351, December 2022., 2022 Abstract Homelessness poses risks to the health and safety of young adults; particularly among sexual and gender minority (SGM) young adults. The current study sought to better understand service use and perceived safety in community and service settings among SGM and cisgender heterosexual (cis‐hetero) young adults experiencing homelessness. Data come

Improving ecological niche models by data mining large environmental datasets for surrogate models [PDF]
arXiv, 2005 WhyWhere is a new ecological niche modeling (ENM) algorithm for mapping and explaining the distribution of species. The algorithm uses image processing methods to efficiently sift through large amounts of data to find the few variables that best predict species occurrence.

Entropy, 2014 Ecosystem entropy production is predicted to increase along ecological succession and approach a state of maximum entropy production, but few studies have bridged the gap between theory and data.
