The relative impacts of different types of land use on the surface water quality are yet to be ascertained and quantified. In this paper, the influence of different types of land use on surface water quality is investigated. Rain events samples from different land use in the central plateau, Iran, were analyzed for major ions. Statistical analyses were employed to examine the statistical relati...
This study analyzes the characteristics of land use/land cover change in Jordan’s Irbid governorate, 1984–2018, and predicts future land use/land cover for 2030 and 2050 using a cellular automata-Markov model. The results inform planners and decision makers of past and current spatial dynamics of land use/land cover change and predicted urban expansion, for a better understanding and successful...
The main purpose of this paper is to explain the factors affecting the change of service land uses in the city of Shiraz and identify its reasons. For this purpose, the second-order confirmatory factor analysis technique has been used as one of the structural equation modeling techniques to determine the severity of the effect of the four factors on land use change, through which a contributing...
red: morph-specific contest success and survival rates in a colour polymorphic agamid lizard. Animal Behaviour 74:337-341. in females is also lateralized: left-eye bias during aggressive courtship rejection in lizards. Assessment in contests of male lizards (Anolis carolinensis): how should smaller males respond when size matters? Animal Behaviour 69:1325-1336.
This study investigated body surface temperature (Tbs) in 22 lizards of 18 species. The difference between Tbs and ambient temperature (Ta) was correlated with size. The greater Tbs 2 Ta differentials, which were recorded in larger lizards, may occur as a result of heat transfer from the core to surface in prevention of overheating. The structure of the integument may contribute to heat dissipa...
An experimental approach was taken to evaluate the role of phenotypic plasticity in reptile coloration for three lizard species which exhibit dramatic variation in dorsal body darkness associated with different substrate environments. In southern New Mexico, blanched color morphs of Aspidoscelis inornata, Holbrookia maculata, and Sceloporus undulatus inhabit the gypsum dunes of White Sands, and...
We performed a laboratory common-environment study to determine the genetic and environmental sources of variation in growth rates of the sagebrush lizard (Sceloporus graciosus). Hatchling lizards were reared from gravid females collected from three study populations along an elevational gradient in southern Utah, USA. Hatchlings were fed ad libidum and were maintained on a 14:10 light:dark cyc...
Lizard is a lightweight stream cipher proposed by Hamann, Krause and Meier in IACR ToSC 2017. It has a Grain-like structure with two state registers of size 90 and 31 bits. The cipher uses a 120 bit Secret Key and a 64 bit IV. The authors claim that Lizard provides 80 bit security against key recovery attacks and a 60-bit security against distinguishing attacks. In this paper, we present an ass...
Tails are important for dynamic stabilization during falling and jumping in lizards. Yet, tail autotomy (the voluntary loss of an appendage) is commonly used for predator evasion. How tail autotomy affects locomotor performance and stability remains poorly understood. Here, we challenge an arboreal lizard to run along surfaces of different breadths with and without an intact tail. Results indic...
land-use spatial allocation is a multi-objective collaborative spatial optimization methodfor rational use of the land use. based on global search capabilities and the information feedbackmechanism of ant colony optimization (aco), a land-use spatial allocation model (aco-la) isproposed. firstlyfirst, a construction graph is built for modeling the land-use spatial allocationproblem. secondlysec...
