The Archaeology of Hittite Imperialism and Ceramic Production in Late Bronze Age IIA Tarsus-Gözlükule, Turkey
… signaled a change in the material culture of Tarsus-Gözlükule, an urban center in Cilicia, southern Turkey. Written sources and archaeological evidence indicate that the LB IIA coincided with the expansion of the Hittite Empire into the region. Previous scholarship has understood the changes …

Modelling growth patterns of bird species using non-linear mixed effects models
… length, bill (culmen) length, foot length, and tarsus length) for Grey-headed Gulls populating Bonaero Park and Modderfontein Pan in Gauteng province, South Africa, and for Swift Terns on Robben Island were taken. Different methods such as polynomial regressions, non-parametric models and …

Handling the heat: managing microclimates for nesting desert hornbills
… all correlated with chick mass and tarsus length, and nest success; chicks were smaller during hotter weather, and less likely to fledge from uninsulated boxes compared with insulated boxes. However, nest box type, breeding season, and air temperature were also correlated with one …

Differential growth of body components among coexisting passerines in response to nest predation risk
… faster growth rates of wing chord, but not tarsus, compared with body mass. Furthermore, species with higher nest predation rates achieved adult-sized tarsi and 60% of adult wing-chord lengths at relatively smaller body mass, further demonstrating the prioritization of wing and tarsus …

Aspectos da ontogenia do Jacu-guaçu (Penelope obscura bronzina Hellmayr, 1914), segundo levantamento em cativeiro
… up to 6 months. The measures of the culmen, tarsus and wing and the weight of the young were taken biweekly. The wing had the greatest relative growth in the first 15 days, while the culmen, tarsus and the weight had grew most during the first 4 weeks. Except for weight, the coefficients of …

Intercalary Regeneration in Larval Ambystoma Limbs: The Origin of Skeletal Structures and The Non-Segmental Organization of Morphogenetic Information
… is derived from the stump when wrist or tarsus blastemas are grafted to the mid-stylopodium of the fore- or hindlimb. The transplanted prospective autopodium forms no more than would be expected in situ. Thus, the rule of distal transformation is not violated during intercalary …

A population biology of breeding redshanks (Tringa totanus L.)
… of pulli were described for weight, bill length, tarsus length and postnatal moult. For three days after hatching the weight remained below the hatching value and then rapidly increased, whereas the bill and tarsus showed a linear increase in length A tentative model of the population dynamics was …

Mechanics of Righting Behavior in the Tarantula (Theraphosidae)
… rotates the prosoma primarily with the tarsus of the right second and third legs, while G. rosea uses the patella of the right third leg to rotate the prosoma. The efficiency with which tarantulas conduct this stereotypical behavior displays how such morphologically complex organisms can …

Black and turkey vulture roost dynamics, marking, morphology and nesting in Virginia
… vultures. Teflon bands did not constrict the tarsus, but tag loss was high. Adult black vultures had longer tarsi and shorter wing chords than juveniles. Two nests were used in 1983 and 1984 by two pairs of black vultures, consisting of one marked and one unmarked bird.

The Cellular And Genetic Mechanisms Underlying Morphological Diversity Of Insects
… in milkweed bugs and the length of the tibia and tarsus in crickets. Additionally, <i>Acheta nub</i>-depleted individuals loose a joint between the tibia and tarsus that leads to their fusion. This finding is significant because it provides the first evidence for the role of nub in leg …

Linear control model of the spinal processing of descending neural signals

Multi-scale characterization of swine femoral cortical bone and long bone defect repair by regeneration
… one bone of the dual skeletal element hind limb tarsus bone in adult Xenopus laevis frog. HDDA scaffolds were soaked with two growth factors: BMP4 and VEGF. Defects in control frogs were left empty, or were implanted with scaffolds lacking growth factors. The limbs were harvested at a series of …

Population ecology of wood ducks in Nevada under experimental manipulation of harvest
… affects the mortality process. I also measured tarsus length during autumn and spring to investigate population level differences in structural body size before and after the hunting season to understand selection on body size during the hunting season. My results support the compensatory …

Extrapair mating behaviors in the field sparrow: nocturnal singing and extraterritorial forays
… females, or females’ social mates (age and tarsus length) and EPP. Thus, proximity to females, rather than male characteristics, appears to be key for a male’s success at acquiring extra-pair paternity. Finally, my findings are consistent with the hypothesis that female choice for extra-pair …

Characterization of the early stages of long bone regeneration in fractures and critical size defects in Xenopus Laevis
… implanted in the critical defect site in the tarsus of the Xenopus Laevis. Defects in control frogs were left empty. Fractures were also induced in some frogs to study the mechanisms of endochondral ossification. The limbs were harvested at a series of early time points ranging from 3 days to …

Copper Metallurgy in Cilicia and the Amuq in the Second Millennium BC: Insights into Aspects of Bronze Age Technology and Trade
… of copper objects from the Bronze Age sites of Tarsus, Kinet, and Tell Atchana in the plains of Cilicia and Amuq in southern Turkey, to examine both the possible sources of the metal and the techniques by which this material was manufactured into finished artifacts. The observed patterns of …

The Breeding Ecology of Least Bitterns (Ixobrychus exilis) at Agassiz and Mingo National Wildlife Refuges

Aspects of American Bittern Ecology in Northwest Minnesota
… Accuracy of predicting sex based on oill and tarsus length was 93%. Upland nests produced more fledglings per nest than wetland nests. The restoration and preservation of shallow wetlands and tall grasslands are recommended as management practices to benefit American bitterns. Additional …
