Despite considerable research effort, it remains unclear whether extra-pair fertilizations (EPF) drive the evolution of male secondary ornamentation in socially monogamous systems. In this study, we test the hypothesis that EPF contribute to the evolution or maintenance of male feather ornamentation in a sexually dichromatic passerine, the Scarlet Rosefinch, Carpodacus erythrinus. We show that ...

The aim of this White Paper was to review the current recommendations for strength training of older adults, to promote physical therapist best practice and achieve optimal functional outcomes. A secondary intent was to encourage prospective researchers to use published guidelines to establish an adequate strength stimulus for patients in their research, rather than perpetuating "usual or tradi...

Bridges only forward The DECbridge 500 product traffic destined for other connects Ethernet/802.3 LANs; local traffic is local area networks (LANs) confined to its home LAN. to fiber distributed One important function of data interface (FDDI) bridges is the ability, LANs and is, therefore, under network management a fundamental element of control, to block traffic an extended LAN. Developers of...

The lamprey belongs to the phylogenetically oldest group of vertebrates that diverged from the mammalian evolutionary line 560 million years ago. A comparison between the lamprey and mammalian basal ganglia establishes a detailed similarity regarding its input from cortex/pallium and thalamus, as well as its intrinsic organisation and projections of the output nuclei. This means that the basal ...

OBJECTIVE To report the outcomes of 500 robotically assisted laparoscopic radical prostatectomies (RALPs), a minimally invasive alternative for treating prostate cancer. PATIENTS AND METHODS In all, 500 patients had RALP over a 30-month period. A transperitoneal six-port approach was used in each case, with the da Vinci robotic surgical system (Intuitive Surgical, Sunnyvale, CA, USA). Prospec...

Tetraethylaluminates of the divalent lanthanides ytterbium and samarium were grafted onto large-pore cubic periodic mesoporous silica (PMS) KIT-6, which had been dehydroxylated at 500 degrees C (specific surface area a(s): 500 m(2)g(-1); mesopore volume V(p): 1.06 cm(3)g(-1); main pore diameter: 85 A). The bimetallic materials [Ln(AlEt(4))(2)]@KIT-6(-500) were analysed by DRIFT spectroscopy, el...

BACKGROUND AND PURPOSE The aim of the study was to determine whether the Agatston calcium score might be applied as a useful tool for evaluation of carotid stenosis. METHODS A total of 124 carotid bifurcations were examined with multidetector row CT. Calcium scores were determined according to the method described by Agatston et al. RESULTS Agatston scores generally appear appropriate for e...

Numerous studies have tested for indirect selection on female extra-pair reproduction (EPR) by quantifying whether extra-pair young (EPY) are fitter than their within-pair young (WPY) maternal half-siblings. In contrast, the hypothesis that offspring of EPY and WPY (rather than the EPY and WPY themselves) differ in fitness has not been tested, even though inter-generational effects of parental ...
