This paper is a study of diversity and seasonal abundance of soil inhabiting arthropod fauna and their interrelationships with the edaphic factors like temperature, moisture and pH in flower garden, vegetable garden and uncultivated area dominated by weeds in Ramakrishna Mission Ashrama Campus, Narendrapur, South - 24 Parganas, West Bengal. The soil arthropods were collected with the help of Berlese-Tullgren funnels. Altogether, 591 arthropods belonging to 7 different groups viz., Acarina, Arachnida, Collembola, Coleoptera, Diptera, Hymenoptera and Psocoptera were extracted from each of the three plots every month during the entire survey period (August 2018 – July 2019). Microarthropod abundance was found to be greater in uncultivated areas (266 individuals) as compared to that of the flower and vegetable gardens where different agronomic practices are adopted and traditional means of garden nurturing viz. tilling, raking, weeding, etc. are followed. Of the total population in all three plots, mites were the most dominant group (37.06%), followed by ants (25.21%) & springtail (19.29%) populations. Soil arthropods populations are greater in the monsoon season (227 individuals), followed by premonsoon (188 individuals) & postmonsoon (176 individuals).

Habitat destruction and poaching has been a major threat to wildlife species. In Kainji Lake National Park, the present population of Pangolin (Phataginus tetradactyla) is not certain. Therefore, this study documents the distribution and abundance of Pangolin in Borgu Sector of Kainji Lake National Park. Data were collected using the line transect method for a period of five (5) months. The data were analyzed using descriptive statistics, and displayed in the form of tables, chart and graphs. The findings show that Awwal Ibrahim tract had the highest percentage (29.7%) of observation of pangolin during the five month period of study (March– July, 2018), and the least observation was sighted in Gilbert child and Mamud Lapai tracks - with 16.2%, respectively. The month of March had the highest number of observation (10) and the month of June had the least number of observations (5). The Population structure of pangolin (P. tetradactyla) revealed that adult recorded the highest observation (26) and the least observation was recorded among young individuals (11). The vegetation distribution of pangolin revealed that riparian forest recorded the highest percentage (29.7%) of sightings, followed by Isoberlina doka woodland and Acacia complex (18.9%, respectively) while the least was Detarium microcapum areas - with (16.2%). Our study also revealed that in the different activities carried out by pangolin, running recorded the highest observation (14), followed by feeding (11) and the least was resting (4). The study recommended that, the park authority should intensify anti-poaching patrols so as to stop humans from entering the park and to minimize indiscriminate deforestation, bush burning and farming activities in the area, so as to allow wildlife to have enough cover and feed for survival.

Amphibia is a class of vertebrate. Amphibians are ectothermic, or cold-blooded, and they have smooth skin that must stay moist to prevent desiccation. They play an important role in nature both, as predator and prey. Nagaland is one of the north eastern hilly states and it is very rich in biodiversity. Due to the geographical position, Nagaland has a huge number of amphibian fauna. Purpose of the present study is to get information of sociocultural relation of frog and Naga people and to study the diversity. Study was conducted through the market survey and interview. Interview was conducted among the people of different age groups which are belonging to different tribes. Frog species were collected from the markets and Morphometric measurements were taken by using a vernier caliper. Frog samples were kept as museum specimen. From the investigation, all together 11 species from 4 families were recorded from the market and identified with the help of relevant literature. Cooking procedure of frog meat among the people of Nagaland varies from tribe to tribe and people to people. Most common method of consumption is boiling with bamboo shoot. Naga people have traditional believe that frogs have medicinal purposes. Different body parts of the frog are consumed by different way to cure the various diseases. Frog eating is a traditional way and continued practice among the Naga society from the time of civilization to obtain the protein, and frogs are easily available in the markets in both, as fresh and dried. Frogs are being exploited from nature from year after year without having proper maintenance and conservation. The results of the study revealed that there is no reduction in frog population, though they are being collected in a huge number. It is necessary to culture the frog species and to establish socio-ecological system through a sustainable management and conservation of biodiversity.

Approximately 1/2 of the macronucleoplasm of wild-type cells of Paramecium tetraurelia was transplanted into d4-84 mutant recipient homozygous for mutations nd3a (non-discharging trichocysts) and ts401 (temperature sensitive). After injection, 30% of surviving cells shifted from mutant to wild-type phenotype. Among the remaining cell lines 29% were unable to eject any trichocysts, and 41% discharged less than 10 of them per cell, when tested with picric acid. Observations were made through two successive vegetative fissions. These results showed that 30% of d4-84 cells contained foreign gene responsible for trichocyst discharge and produced cell lines of the wild-type phenotype, in which the expression as well as replication of this gene appeared normal.

The grasshopper Podisma sapporensis consists of two main chromosome races in Hokkaido. The western group of populations of P. sapporensis, belonging to the XO race, has a diploid number of chromosomes 2n=23 in the male and 2n=24 in the female (sex determination XO male/XX female). The eastern group of populations of this species, belonging to the XY race, differs from the western one as a result of Robertsonian translocation between the originally acrocentric X chromosome and M5 autosome in homozygous state, having resulted in the forming of chromosome sex determination neo-XY male/neo-XX female (2n=22). These races are geographically isolated by the mountainous system consisting of the Mts Daisetsu and Hidaka range, occupying the central part of the island. The hybrid zones between the races have not so far been discovered. Various levels of polymorphism for the pericentric inversions and C-banding variation exist in different chromosomes throughout populations in both chromosome races. In some solitary populations (the population at the summit of Mt Yotei, populations in the vicinity of Naganuma, Oketo, and Tanno) pericentric inversions are fixed in some pairs of chromosomes, which enables marking of the discrete karyomorphes. In the Mt Daisengen population all chromosomes are two-armed as a result of fixing the pericentric inversions. These facts contradict karyotypical conservatism of the tribe Podismini. The level of diversity of P. sapporensis karyotypes could provide a new perspective on the evolutionary process of different karyotype in Orthoptera. The considerable occurrence of polymorphism in chromosomes suggests that karyotypic diversification is undergoing in P. sapporensis. The authors also proposed that P. sapporensis would be divided into four chromosome subraces in the XO chromosome race and two chromosome subraces in the XY race, on the basis of karyotypic features. These races may have been established by fundamental climatic changes during the glacial epoch.

Stereological analysis of the ultrastructure of primordial germ cells (PGCs) and the somatic (ectoderm) cells in two developmental stages of embryos and freshly hatched juveniles of Allacma fusca have shown great differences in mitochondria volume density (vd) between the two types of cells. In younger embryos (migration phase of the PGCs) the vd of mitochondria in the cytoplasm of the PGCs is 74.64% higher than in the ectoderm cells. In older embryos, (PGCs in the gonads) the vd of mitochondria is 123% higher than the corresponding value for the somatic cells cytoplasm. In the juvenile the vd of mitochondria in the ectoderm cells grows twice but is still only 2/3 of the value for the PGCs. On the basis of papers describing a direct relationship between stereological and physiological results the authors conclude that the metabolism of the primordial germ cells during embryonic development of Allacma fusca is much higher than that of the somatic ones. If the above conclusion is correct, the results presented here confirm the ?disposable soma theory? (Kirkwood & Holliday 1979).

Little is known about the physiological events occurring in the chicken ovary during a pause in laying, therefore the aim of the present study was to examine changes in sex steroid concentration in the follicle wall and blood plasma during cessation of egg laying. The experiment was performed on laying Isa Brown hens. Control hens were fed ad libitum whereas the experimental ones were subjected to a pause in laying by complete food deprivation for 5 days and water deprivation on 3 day followed by feeding every second day up to 9 day and then ad libitum. Blood samples were taken from the wing vein each day. The hens were decapitated on day 3, 6, 9, and 16. The ovary was isolated and the following follicles were dissected: white (1-2; 2-4; 4-6; 6-8 mm) and yellow preovulatory ones (F1-F3). Progesterone and estradiol were measured in the follicle wall and blood plasma by RIA methods. The hens stopped egg laying on day 4 and began egg restoration on day 14 of the experiment. Cessation of egg laying was preceded by a decrease in estradiol and progesterone levels in the ovary as well as in the blood plasma. The plasma level of these steroids began to increase 7 days before the start of egg restoration. Autopsy of the ovary showed that the atrophy of the chicken yellow preovulatory follicles during the pause in laying was accompanied by a significant increase in the total number of white follicles.

The present study is on the spider fauna of Barasat and Basirhat of North 24 Parganas, West Bengal, India. A total of 23 species belonging to 20 genera and 11 families are sampled during the period August 2016 to July 2017. These include the newly recorded species, Anepsion maritatum (O.P. Cambridge) from the state. The dominant guild is constituted by the Orb web weavers (30.43%). Analysis of their zoogeographical distribution reveals that the fauna apart from being Oriental also includes some Australian (23%), Palaearctic (21.73%) and Ethiopian, Nearctic and Neotropical (each 17.39%) elements. Spiders are mostly prevalent during Postmonsoon (82.60%), followed by Premonsoon (60.86%) and Monsoon (47.82%) which is in conformity with the incidence of the insect species. Two species namely Eriovixia excelsa (Simon) and Leucauge decorata (Blackwall) are recorded throughout the period of survey. All the diversity indices are higher in case of Basirhat as compared to Barasat. An overall negative impact of urbanization on spider diversity, distribution and abundance is evidenced from the present study. Ranking sequence of the most abundant species (six) in descending order are: Leucauge decorata (25.68%) > Eriovixia excelsa (19.13%) > Pholcus phalangioides (11.48%) > Plexippus paykullii (8.74%) > Anepsion maritatum (7.10%) > Cyrtophora cicatrosa (6.56%). Sex ratio (♀ : ♂) is about 12 : 1. Availability of food/season and/or cannibalism may be the factors for female dominated society.

A total of one hundred and twenty ducklings (i. e. 60 Muscovy and 60 Mallard) were used for the study to evaluate the breeds effect on growth performance and prediction of body weight using linear body measurements of two breeds of ducks with the aid of General Linear Model and stepwise regression procedure of SPSS. Data on individual body weight (BW), body height (BH), body length (BL) breast circumference (BC), thigh length (TL), bill length (BIL), wing length (WL)and shank length (SL) of 120 ducks were collected on Muscovy and Mallard ducks and used to predict body weight at 4 and 8 weeks. The results showed that Muscovy (56.6t ± 6.7 – 1037.5 ± 30.29g) was significantly superior (P<0.05) to Mallard (51.8 ± 1.66 – 875.44 ± 70.30g) in body weight and in all the linear body measurements from day old to week 10. Individual body weight and linear body measurements was predicted at various ages (4 and 8 weeks) by genetic groups. The values of the coefficient of determination (R2) ranged from (88.6 – 97%) and (81.8 – 90.3%) in Muscovy and Mallard respectively at week 4. While, (R2) ranged from (58.7 – 92%) and 80.1 – 86.9%) in Muscovy and Mallard respectively at week 8. Since linear body measurements that can readily predict body weight without ducks being slaughtered, it is therefore, highly desirable as it will ensure the selection of animals that will reach market weight and size at relatively faster rate. This will also serve as a tool for breeders in selecting animals destined for use as breeding stock. These Muscovy and Mallard can be improved by exploiting the principle of phenotypic plasticity to obtain strains to complement other breeds of duck. Muscovy can also be used to upgrade some other indigenous ducks for better performance in a systematic breeding program.

In the present study the effects of adrenal corticoids, both natural and synthetic, namely cortisol and dexamethasone respectively, was observed on the thyroid gland cell morphology and proliferation in neonatal male chicks (Gallus domesticus). Cortisol was injected at a dose of 4 mg/100 g body weight and dexamethasone at a dose of 1 mg/100 g b.w. subcutaneously daily for fifteen consecutive days. The control birds were similarly injected with normal saline at a daily dose of 0.2 ml per bird for the same time period. The results indicated that both cortisol and dexamethasone caused a significant decrease in thyrofollicular cell height. On the contrary, a significant increase in the ratio of the follicular diameter to the number of nuclei per follicle i.e. D/N value was observed in both cortisol and dexamethasone treated chicks. It was also observed that both cortisol and dexamethasone induced suppression of mitotic activity, as evidenced from a significant decrease in mitotic percentage compared with the control chicks. The present authors? studies thus indicate that adrenal corticoids act as inhibitory modulators of thyroid follicular activity as regards karyomorphology and cell proliferation.

The hypothesis that parasites and pathogens select for polyandry in eusocial Hymenoptera was tested, using the honey bee Apis mellifera and its microsporidian parasite Nosema apis. Five honey bee colonies with low and five with high worker genetic diversity were infected with N. apis spores. At 54-56 days after inoculation, parasite spores in the workers? midguts were counted to determine whether there was a greater variation of infection intensity (spore counts per worker) in high-diversity colonies than in low-diversity ones. In all colonies there were two discrete sets of workers, with few or many parasite spores. To compare the variations of infection intensity between two colony groups, coefficients of variation were calculated for all workers examined, and for the slightly infected and strongly infected workers. The percentages of slightly infected workers in the low- and high-diversity groups were also compared. None of the comparisons between low- and high-diversity colonies showed significant differences, therefore no relation was found between honey bee workers? genetic diversity and their infection with N. apis.

The objective of this study accomplished a knowledge survey of the Bororo indigenous on the birds of natural occurrence in their territory, Meruri village, who is located in the Mato Grosso State, Brazil, in the Savannah biome, and also the relationship of the indigenous with these birds. As the method for collect, the data were used open and semi-structured interviews. Twenty-two indigenous were interviewed, both genres and different ages. The interviewees mentioned 96 species of birds and they showed wide ecological knowledge regarding these birds. Such relationships are complex, being evidenced by a mythical interaction between the man and the elements of nature. These birds are important elements in the creation of stories, legends, in the Bororo ceremonies and arts. The oral transmission of knowledge occurs across generations.

Knowledge on the behavioural pattern of fauna species help to maintain good relationship with captive animals. Chimpanzee behavioural pattern differs in many ways with human interactions. The research focused on the effects of tourist participation on Chimpanzee behavior in a captive environment. Fifty copies of Semi-structured questionnaire were administered to the tourist. Chimpanzee activities and interactions with tourists was carried out using standard focal sampling method at 5 minutes interval for 2 days per week for two months. Data were analyzed using descriptive statistics, Mantel-Haenszel χ2 and Cochran-Mantel-Haenszel (CMH) M2 test. The study reveals that majority of the respondents were males (60%) and were first timers who came for the purpose of relaxation and research. The probability of return visit by the respondents was low, due to poor rating of the Zoo. Most of chimpanzee time was spent resting, sitting and standing (29.5%, 23.2% and 17.0%), respectively. The locomotive and display behavioural pattern were statistically significant (p-value = 0.042 and 0.042) at contact and non-contact level. However, there was no statistically difference with the relieve behavioural pattern exhibited by the Chimpanzee, which indicates that, the relieved behaviour observed was independent of non-contact and contact between the Chimpanzee.
