Abstract:
Dibenzoylhydrazines Xa-(C6H5)a-CO-N-(t-Bu)-NH-CO-(C6H5)b-Yb are efficient insect growth regulators with high activity and selectivity toward lepidopteran and coleopteran pests. For 123 congeneric molecules, a quantitative structure activity relationship model was built in the framework of the QSARINS package using 2D, Topology-based, PaDEL descriptors. Variable selection by GA-MLR allows building an efficient multilinear regression linking pEC50 values to nine structural variables. Robustness and quality of the model were carefully examined at various levels: data-fitting (recall), leave-one (or some) - out, internal and external validation (including random splitting), points not in depth investigated in previous works. Various Machine Learning approaches (Partial Least Squares Regression, Projection Pursuit Regression, Linear Support Vector Machine or Three Layer Perceptron Artificial Neural Network) confirm the validity of the analysis, giving highly consistent results of comparable quality, with only a slight advantage for the three-layer perceptron.

Abstract:
Male monstrilloid copepods, described herein as Monstrillopsis paradoxa sp. nov., were collected from the Chuja Islands, Jeju, Korea, using a light trap. They display many of the common features of Monstrillopsis, including large, prominent eyes, an anteriorly positioned oral papilla, and four setae on each caudal ramus. Type-2 modification of the antennules further supports the assignment of the new species to Monstrillopsis. However, the present specimens have an unusually low number of urosomal somites, just three in total, compared to five in males of all congeneric species, and from four (in Cymbasoma) to five in males of all other monstrilloid genera. Up until now, in the Monstrilloida only females of Cymbasoma have been known to have as few as three urosomal somites.

Abstract:
Pollinator insects forage in complex and unpredictable resource landscapes, often using social information from congeneric individuals to acquire knowledge about their environment. It has long been recognized that this process allows them to exploit floral resources more efficiently and thus increase individual fitness. However, by creating correlations between the behaviors of pollinators within a population, this could also indirectly influence the entire plant-pollinator community. One type of social information used by pollinators is the scent mark left on the corolla of flowers by previous visitors, which can be used as a cue to avoid recently depleted resources. We developed a spatially explicit agent-based model to examine the effects, at both individual and community levels, of pollinators using these scent marks. The model simulates a population of pollinators foraging on flowers in a continuous 2D space in which we can vary the density of pollinators. We showed that the use of scent marks as a source of information significantly increased the foraging efficiency of pollinators except when competition between pollinators was very low. At the community level, this also resulted in a marked homogenization between floral resources within the landscape: in the absence of scent marks, the coefficient of variation of the remaining nectar quantity per flower strongly increased with greater pollinator competition, but it remained low at all levels of competition when scent marks were used by the pollinators. Finally, the use of scent marks markedly decreased the number of pollinator flower visits, especially at high levels of pollinator competition, which can potentially reduce the pollination service.

Abstract:
This study described the growth, mortality, recruitment pattern and exploitation rate of the Buried fan scallop (Mimachlamys funebris) in Asid Gulf, Philippines. Monthly length-frequency data (N=3988) from April 2018 to March 2019 were used to examine population parameters using FISAT II. Two estimates of natural mortalities were used to compare variability of limit exploitation rates. Modelling through the oscillating von Bertalanffy growth function revealed that the species is fast growing (K=1.1 year–1) attaining SH∞ of 10.5 cm. Adequacy in the use of the sinusoidal version of the growth formula hinges on the mean annual temperature difference reported in the gulf to be 2°C. Recruitment pattern was continuous and bimodal throughout the year with two high pulses in April–May and September consistent with the reproductive seasonality reported for congeneric species. Fishing mortality coefficients (4.26 and 4.82 year–1) were higher than the natural mortality coefficients (0.543 and 1.1 year–1). Yield and biomass-per-recruit analysis showed that the current exploitation rates are 112% (Ecurr1 = 0.90) and 92% (Ecurr2 = 0.80) higher than the biological reference points adopted for the study particularly E50. These results demonstrate that M. funebris stock is overexploited, which necessitates effective management measures including mariculture.

Abstract:
The concept of generic diversity expresses the ‘diversification’ of species into genera in a community. Since niche overlap is assumed to be higher in congeneric species, competition should increase generic diversity. On the other hand, generic diversity might be lower in highly selective environments, where only species with similar adaptations can survive. We used the distribution of tenebrionid beetles in Central Italy to investigate how generic diversity varies with elevation from sea level to 2400 m altitude. Generic diversity of geophilous tenebrionids decreased sharply with elevation, whereas the generic diversity of xylophilous tenebrionids showed similarly high values across the gradient. These results suggest that geophilous species are more sensitive to variation in environmental factors, and that the advantages of close relationships (similar adaptations to harsh conditions) are greater than the possible drawbacks (competition). This is consistent with the fact that geophilous tenebrionids are mostly generalist detritivores, and hence weakly affected by competition for resources. By contrast, xylophilous species are more protected from harsh/selective conditions, but more limited by competition for microhabitats and food. Our results support the environmental filtering hypothesis for the species composition of tenebrionid beetles along an elevational gradient.

Abstract:
Executive Functioning (EF) is a construct that encompasses multiple interrelated higher order skills, however, conceptualising the nebulous construct remains challenging. This paper outlined several areas of research contributing to the difficulties and challenges associated with the operationalisation of EF which pose significant challenges for the validity of psychological assessment. It was the contention of the study to confirm the validity of Anderson’s (2002) paediatric model of Executive Function in a healthy adult population. Hypotheses specified that; 1) All four constructs (Attentional Control (AC), Cognitive Flexibility (CF), Information Processing (IP), Goal Setting (GS)) purported by Anderson would be upheld mathematically, 2) Attentional Control would be the strongest predictor, explaining the greatest variance in all other latent constructs. Thus, attention would be a significant domain that warrants its theoretical consideration within a model of EF, and not separate to it, and 3) Information Processing would be the second strongest predictor of other latent constructs, therefore demonstrating that IP is an influential component in a model of EF. One hundred and thirty-three adults (42 male and 91 females) aged between 18 and 50 (M=29.68, SD=7.46) completed a cognitive test battery comprising 22 tests. Of the 57 variables analysed, data reduction yielded 23 for further analyses. CFA revealed all four constructs of Anderson’s model upheld, however findings imply Attentional Control as represented by more posterior attention tasks does not significantly explain EF performance at a higher level, but rather, the speed with which an individual is able to process and respond to task demands is a mediating factor in performance. The work of Peter Anderson (2002) over a decade ago has proven an exceptional platform from which to explore definitions, tests and constructs of EF, and by building his work this study has made significant advances toward a hierarchical model of EF and more importantly, the mechanisms critical to efficient functioning at the highest level of complexity. This thesis has reconciled various issues highlighted within the literature and offers a number of conclusions and directions for future research.
