The hip region is examined to determine what aspects of musculoskeletal anatomy are precociously developed in primate species with highly specialized modes of locomotion. Muscles of the hind limb were removed and weighed in each specimen, and the hip joint of selected specimens was studied in stained serial sections. No perinatal differences among species are evident, but in adults, the hip joi...

In this experiment, 0, 0.125, 0.25, 0.5, and 1.0 ml of each oil dissolved in 1 ml of 95 % ethanol was added to 1 kg of soil containing 370 P. penetrans per kg, and incorporated by shaking. After 10 days at 22 ± 3 C, a four-week-old tomato (Lycopersicon esculentum Mill cv. Bonny Best) seedling was planted in each of six 5-cm-diam plastic pots containing 100 g of treated or untreated infested soi...

Field experiments were conducted in 1982 and 1983 to assess interactions between Heterodera glycines and Pratylenchus scribneri on soybean in southern Illinois. Soybean cyst nematode susceptible cultivar Williams 79 and resistant cultivar Fayette were treated or not treated with aldicarb 15G. Initial population densities were 35 H. glycines cysts containing eggs, 100 P. scribneri, 30 Helicotyle...

Plant-parasitic nematode population densities were determined from 325 root and soil samples collected from vegetable growing areas in Pakistan. Yield losses associated with nematode presence were quantified on 19 vegetable crops during 2007 and 2009. The most abundant plant-parasitic nematodes detected, in order of decreasing frequency of infestation (percentage of samples), were Meloidogyne i...

Spatial patterns of Meloidogyne incognita, Tylenchorhynchus claytoni, Helicotylenchus dihystera, and Criconemella ornata were analyzed using Hill's two-term local quadrat variance method (TTLQV), spectral analysis, and spatial correlation. Data were collected according to a systematic grid sampling plan from seven tobacco fields in North Carolina. Different estimates of nematode cluster size we...

The distribution of nematodes was studied in rice fields in Guilan province, Iran, from 2014 to 2016. Nematode biodiversity of 250 soil and root samples was examined. Thirty nematode species were identified morphologically, including plant parasites, microbivores and mycetophagous and predator species. Molecular techniques were also used for further identification of three plant parasitic speci...

Gross and histologic aspects of facial expression muscles are presented here for Otolemur spp. (suborder Prosimii, family Lorisidae) and are compared with those of lemuroids. Muscles of facial expression are involved in social signaling among primates, and are a primary means by which close-proximity nonverbal communication is achieved. These muscles have been well described in catarrhines and ...
