1. Scorpions and life-history strategies: from evolutionary dynamics toward the scorpionism problem
Abstract This work aims to contribute to the general information on scorpion reproductive patterns in general including species that can be noxious to humans. Scorpions are unusual among terrestrial arthropods in several of their life-history traits since in many aspects their reproductive strategies are more similar to those of superior vertebrates than to

2. Fitness cost in field Anopheles labranchiae populations associated with resistance to the insecticide deltamethrin
Abstract We evaluated in the present study the effect of deltamethrin resistance on the fitness cost of the filed populations of Anopheles labranchiae. A susceptible population was used as reference to do different comparisons. We selected the most resistant larvae population collected from northern Tunisia. Eggs were used for study of life history traits in

3. Genetic diversity and population structure of Vriesea reitzii (Bromeliaceae), a species from the Southern Brazilian Highlands
Abstract The Southern Brazilian Highlands are composed by a mosaic of Mixed Ombrophilous Forest (MOF) and grassland formations, an interesting landscape for the study of population structure. We analyzed the genetic diversity within and among populations of the MOF-endemic bromeliad Vriesea reitzii by genotyping seven nuclear microsatellite loci in 187 indiv

4. Effects of temephos resistance on life history traits of Aedes albopictus (Skuse) (Diptera: Culicidae), a vector of arboviruses
Abstract The effects of temephos resistance on the fitness cost of the wild populations of Aedes albopictus was evaluated. The larvae of two wild populations were exposed to the diagnostic dose of 0.02 mg and 0.012 mg/L. The larvae which survived after the 24 h exposure to diagnostic dose were considered as resistant and F1 generations were chosen for the co

5. Do seedling functional groups reflect ecological strategies of woody plant species in Caatinga?
ABSTRACT It is assumed that morphological traits of seedlings reflect different strategies in response to environmental conditions. The ecological significance of this has been widely documented in rainforests, where habitat structure and species interactions play an important role in community assembly. However, in seasonally dry ecosystems, where environme

6. Patterns of growth, development and herbivory of Palicourea rigida are affected more by sun/shade conditions than by Cerrado phytophysiognomy
ABSTRACT Plant development is influenced by several abiotic factors, which in turn influence morphological traits and life history. We investigated whether leaf area, herbivory, toughness, fluctuating asymmetry, structural complexity and the number of inflorescences of Palicourea rigida are influenced by sun/shade conditions or by Cerrado phytophysiognomy (t

7. EVALUATION OF SUBLETHAL EFFECTS OF Ipomoea cairica LINN. EXTRACT ON LIFE HISTORY TRAITS OF DENGUE VECTORS
Plant derived insecticides have considerable potential for mosquito control because these products are safer than conventional insecticides. This study aimed to investigate sublethal activities of Ipomoea carica or railway creeper crude acethonilic extract against life history trait of dengue vectors, Aedes albopictus and Aedes aegypti. The late third instar

8. Life history traits influence in gonad composition of two sympatric species of flatfish
ResumoParalichthys patagonicus e Paralichthys orbignyanusapresentam diferentes atributos nas suas histórias de vida, embora ambas se reproduzam no mar. Paralichthys patagonicus permanece toda a vida em águas abertas, enquanto P. orbignyanus é comumente encontrado em corpos de água salobra. Considerando que redes alimentares marinhas e estuarinas têm dif

9. Insights into the dynamics of hind leg development in honey bee (Apis mellifera L.) queen and worker larvae - A morphology/differential gene expression analysis
Phenotypic plasticity is a hallmark of the caste systems of social insects, expressed in their life history and morphological traits. These are best studied in bees. In their co-evolution with angiosperm plants, the females of corbiculate bees have acquired a specialized structure on their hind legs for collecting pollen. In the highly eusocial bees (Apini a

10. Population genetic structure and body shape assessment of Pagrus pagrus (Linnaeus, 1758) (Perciformes: Sparidae) from the Buenos Aires coast of the Argentine Sea
This study highlights the analysis of the morphological and genetic variation of the common sea bream Pagrus pagrus, and compares its two main areas of concentration: the northern (35ºS - 38ºS) and the southern areas (39ºS - 41ºS) of the Buenos Aires coast of the Argentine Sea. Body shape characterization presented two significantly different morphotypes

11. Autoecology of Dryadosaura nordestina (Squamata: Gymnophthalmidae) from Atlantic forest fragments in Northeastern Brazil
Life history parameters such as diet, reproduction, and sexual dimorphism are crucial to understand ecological and evolutionary forces shaping species traits. Nevertheless, such information is scant in the literature for most Neotropical squamates. Gymnophthalmidae contains over 242 species in 46 genera and includes small-size, mostly terrestrial species, al

12. Biological traits and Life table parameters A and B biotype of Bemisia tabaci (Genn.) on cotton and rapeseed
The aim of this work was to construct life table of Bemisia tabaci (Gen.) A and B (silverleaf whitefly B. argentifolii Bellows and Perring) biotype (Hem.: Aleyrodidae) on two host plants; cotton, (Gossypium hirsutum L.) and rapeseed, (Brassica napus L.). Experiments were conducted in a growth chamber under 24 ± 2ºC, 55±3% RH and 16:8 (L:D) h photoperiod o
