BACKGROUND AND AIMS A test was made of the hypothesis that papilionate legume flowers filter pollinators according to their ability to exert strength to open flowers to access rewards. In addition, interactions with pollen vectors were expected to explain the structural complexity of the architecture of these flowers since operative flower strength may be determined by a combination of morpholo...

The aim of this study was to identify skeletal variations in the lumbosacral junction (LSJ) of the German shepherd dog (GSD) compared with other large breeds. The radiographic traits of the LSJ were investigated in a group of 733 GSDs and a control group of 334 dogs of other breeds that were matched in terms of size. Nine morphological and 17 morphometric traits were recorded and analysed. Furt...

Understanding interspecific morphometric variation is a prerequisite of species identification, evolutionary and taxonomic studies. The external features (i.e. ratios) five Macrobrachium viz., rosenbergii, M. lanchesteri, dolichodactylus, idella lamarrei from three rivers in northern Bangladesh, were used to analyze variation. samples collected Jamuneshwari river, Tangon river Atrai river. Morp...

Women's preferences for men's masculinized faces and voices were assessed after women (n = 331) were primed with images of male-on-male aggression, male-on-female aggression, pathogens, and neutral scenes. Male-on-male aggression and pathogen primes were associated with increased preference for masculine traits, but the same effect emerged in the neutral condition. We show the increased prefere...

Morphometric and meristic studies can be used to identify stocks relationships between populations of fish resources. Lutjanus gibbus is a species commonly found in the waters northern Papua one fishery commodities targeted by fishermen other than groupers. In this study, morphometric characteristics L. snapper from several locations Seas were addressed. The study was conducted June July 2022. ...
