“…Morphometric analysis is the most common method used to identify, and discriminate populations, due to its practicality and low cost (Bartolommei et al, 2016). Morphometric analysis methods are generally based on multiple measurements of various parts of the body, on several individuals (Rattanawannee et al, 2012). The field of geometric morphometrics has matured into a rich and cohesive discipline for the study of shape variation and covariation (Adams et al, 2013).…”

A total of 81 samples captured between November 2017 to September 2019 were morphometrically analyzed as part of this study. In this latter we tried to compare between the population of the dam (artificial environment) and the population of the river (natural environment) in two watersheds for two different species of Luciobarbus in western Algeria. Sites A (natural) and B (artificial) are located at almost the same altitude (285-571 m) whereas sites C (artificial) and D (natural) are located in two different altitudes (285-571 m) and (1078-1821 m) respectively. The analysis of variance (ANOVA) was carried out to test the significance of the variations of each morphometric character between the 4 populations (A, B, C and D). The values of all the external morphometric parameters were the highest in the population of the Boughrara dam followed by El-hammam river and Bouhanifia dam while the population of Chouly river showed the lowest morphometric measurements. The mean of total length (TL) and weight (Weight), for example, of the Boughrara dam were the largest of the four populations (33.03 ± 2.02 cm and 474.46 ± 116.76 g respectively) while those of the river Chouly were the smallest (15.44 ± 1.23 cm and 55.55 ± 13.01 respectively). The sex ratio analysis was performed by studying the overall sex ratio. Females were more abundant than males (1: 1.7). The graphical representation of Quantitative Variables by PCA showed that the morphometric variables are all positively correlated with each other by quite different rates. The Shannon and Weaver index was calculated from the different characters in the four regions studied: A, B, C and D. The region of site B (Bouhanifia dam) had the highest average diversity index with 0.92, followed by the region of site A (El-hammam river) (0.88). The lowest mean value was found in site C (Chouly river) (0.29).

“…These species-specific estimates often derive from limited sampling of one population. However, most of the few existing comparative studies (Corley and Fjerdingstad, 2011; El-Niweiri and Moritz, 2011; Franck et al, 2000) report significant variation of social insect mating behavior (but see Rattanawannee et al, 2012). …”

Geographic variation in polyandry of the Eastern Honey Bee, Apis cerana, in Thailand

et al. 2014

The repeated evolution of extreme polyandry in advanced social insects is exceptional and its explanation has attracted significant attention. However, most reported estimates of the number of matings are derived from limited sampling. Temporal and geographic variation in mating behavior of social insects has not been sufficiently studied. Worker offspring of 18 Eastern Honey Bee (Apis cerana Fabr.) queens from three populations across Thailand were genotyped at five microsatellite markers to test for population differences of mating behavior across three different ecosystems. The number of matings decreased from a northern, more seasonal environment to a southern tropical population and was lowest in a tropical island population. Our study confirms earlier findings that social insect mating behavior shows biogeographic variation and highlights that data from several populations are needed for reliable species-specific estimates of the number of matings. Detailed studies of populations that show significant differentiation in the number of matings may be able to discriminate effectively among the different hypotheses that have been proposed to explain the evolution of polyandry in honey bees and other advanced social insects.

Highly social species are successful because they cooperate in obligately integrated societies. We examined temporal genetic variation in the eusocial wasp Vespula maculifrons in order to gain a greater understanding of evolution in highly social taxa. First, we wished to test if effective population sizes of eusocial species were relatively low due to the reproductive division of labor that characterizes eusocial taxa. We thus estimated the effective population size of V. maculifrons by examining temporal changes in population allele frequencies. We sampled the genetic composition of a V. maculifrons population at three separate time points spanning a 13-year period. We found that effective population size ranged in the hundreds of individuals, which is similar to estimates in other, non-eusocial taxa. Second, we estimated levels of polyandry in V. maculifrons in different years in order to determine if queen mating system varied over time. We found no significant change in the number or skew of males mated to queens. In addition, mating skew was not significant within V. maculifrons colonies. Therefore, our data suggest that queen mate number may be subject to stabilizing selection in this taxon. Overall, our study provides novel insight into the selective processes operating in eusocial species by analyzing temporal genetic changes within populations.
