Pleiotropic and Novel Phenotypes in The \u3cem\u3eDrosophila\u3c/em\u3e Gut Caused by Mutation of \u3cem\u3eDrop-Dead\u3c/em\u3e [PDF]

open access: yes, 2018
Normal gut function is vital for animal survival, and deviations from such function can contribute to malnutrition, inflammation, increased susceptibility to pathogens, diabetes, neurodegenerative diseases, and cancer.

Larvicidal Activity of Phytochemicals From Handroanthus impetiginosus Seeds Against Culex quinquefasciatus

open access: yesChemistry &Biodiversity, EarlyView.
The hexane extract was obtained from the seeds of H. impetiginosus, from which fatty acids and FAMEs were obtained. The three samples were tested on C. quinquefasciatus larvae, promoting mortality with moderate LC50 values. The hexane extract was analyzed by gas chromatographymass spectrometry (GC‐MS), and the most abundant compounds were ethyl oleate (

Statistical methods for detecting genes associated with sperm competition in natural populations of Drosophila, using blocks of tightly linked single nucleotide polymorphisms : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Statistics at Massey University, Albany, New Zealand [PDF]

open access: yes, 2007
The purpose of the project is to develop statistical methods for detecting genes associated with sperm competition in natural populations of Drosophila (fruit flies). The flies' genotype information given by Fiumera et al.

Functional and phylogenetic convergence of winter and breeding bird communities in the northeastern US

open access: yesEcography, EarlyView.
Around the world, ecological communities are becoming more similar to one another in a process known as biotic homogenization – an increase in similarity among communities over time. While biotic homogenization has been widely studied among spatial communities, very little attention has been paid to beta diversity between seasonal communities ...

The scaling of seed‐dispersal specialization in interaction networks across levels of organization

open access: yesEcography, EarlyView.
Natural ecosystems are characterized by a specialization pattern where few species are common while many others are rare. In ecological networks involving biotic interactions, specialization operates as a continuum at individual, species, and community levels. Theory predicts that ecological and evolutionary factors can primarily explain specialization.

Pengaruh Penambahan Beberapa Esens Buah pada Perangkap Metil Eugenol terhadap Ketertarikan Lalat Buah Bactrocera Dorsalis Kompleks pada Pertanaman Mangga di Desa Pasirmuncang, Majalengka [PDF]

open access: yes, 2018
Fruit fly (Bactrocera dorsalis Complex) is one of the major pests in horticultural commodities in Indonesia. In this present study, a control method of formulating methyl eugenol and the addition of fruit essences was tested to attract B.

Most mammals do not wander: few species escape continental endemism

open access: yesEcography, EarlyView.
Terrestrial mammals are found nearly everywhere on Earth. Yet, most taxa are endemic to a single continent; geological, evolutionary, ecological, or physiological filters constrain geographic distributions. Here, we synthesize data on geography, taxonomy, lineage age, dispersal, body size, and diet for > 4000 terrestrial mammals prior to detectable ...

A Survey of Fruit Flies (Diptera: Tephritidae: Dacinae) and their Opiine Parasitoids (Hymenoptera: Braconidae) in Palau [PDF]

open access: yes, 2015
Surveys for fruit flies and their parasitoids, conducted by male lure trapping and host fruit sampling in 2001, 2013, and 2014, demonstrate that the agricultural pests Bactrocera dorsalis, B. frauenfeldi, and B. umbrosa and non- economic B.

An Overview of Current Optimization Approaches for Hybrid Energy Systems Combining Solar Photovoltaic and Wind Technologies

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT This study reviews recent developments in optimization techniques for hybrid solar photovoltaic and wind energy systems, particularly those using artificial intelligence (AI) and hybrid algorithms. Due to the global need for sustainable energy, the study compares both traditional and modern optimization techniques.
