We review our recent low-temperature absorption, circular dichroism (CD), magnetic CD (MCD), fluorescence and laser-selective measurements of oxygen-evolving Photosystem II (PSII) core complexes and their constituent CP 4 3, CP 47 and D1/D2/cytb(559) sub-assemblies. Quantitative comparisons reveal that neither absorption nor fluorescence spectra of core complexes are simple additive combination...

وراثت مقاومت سفیدبالک گلخانه، Trialeurodes vaporariorum Westwood (Hemiptera: Aleyrodidae)، به دو ترکیب ایمیداکلوپرید و کلرپایریفوس مورد مطالعه قرار گرفت. در این پژوهش، از جمعیت فیلستان ورامین (FL) عنوان والد مقاوم فردیس کرج (FR) حساس استفاده شد. مقدار ترتیب حدودا 62/13 91/14 برابر بود. عدم وجود اختلاف معنی‌دار LC50 روی تلاقی‌های F1 (R♂×S♀) Fʹ1 (R♀×S♂) نشان داد که T. نوع اتوزومی (غیرجنسی) است. ه...

The golden-striped salamander is a streamside species endemic to the northwestern corner of Iberian Peninsula. In first half twentieth century, an undisclosed number individuals this were reportedly captured in Buçaco, Central Portugal, and deliberately introduced Sintra Mountains, 170 km south its native distribution range. discovery breeding population during 2015 prompted work: we used neutr...

Several phytoseiid mite species are important natural enemies used in biological control strategies. In the present study, Cytb mtDNA sequences of various populations two species, Phytoseiulus macropolis and P. persimilis, were compared to determine whether specimens collected Brazil could belong persimilis as this latter is reported South America but not Brazil. The marker was because its high...

Gonçalves et al. [1] report an examination of the PCR-based species identification test used to detect foxes from faecal material in the ongoing fox eradication programme in Tasmania. The authors rightly point out that poor design in screening methods may lead to false negative or false positive results and they sought to ‘‘better evaluate the specificity of the putatively fox-specific pair of ...

Background: Haemoproteus columbae is widely distributed in tropical and subtropical regions, causing pseudomalaria in pigeons. Aims: The current study aimed to characterize the phylogenetic position of H. columbae in pigeons in Sharkia province, Egypt, based on partial sequencing of the cytb gene as the conserved regions. The “DNA barcode” of the cytb gene helps in designing primers that can be...

Practical tools to quantify range-wide dietary choices of the polar bear have not been well developed, thus impeding monitoring this species in a changing climate. Here we describe our steps toward non-invasive diet determination with optimization 454 pyrosequencing 136 base pair (bp) mitochondrial cytochrome b (cytb) fragment amplified from extracts captive and wild faeces. We first determine ...
