Morphology and Morphogenesis of the Seed Cones of the Cupressaceae - Part II Cupressoideae
1 2 Bull. CCP 4 (2): 51-78. (10.2015) A. Jagel & V.M. Dörken Morphology and morphogenesis of the seed cones of the Cupressaceae - part II Cupressoideae Summary The cone morphology of the Cupressoideae genera Calocedrus, Thuja, Thujopsis, Chamaecyparis, Fokienia, Platycladus, Microbiota, Tetraclinis, Cupressus and Juniperus are presented in young stages, at pollination time as well as at maturity. Typical cone diagrams were drawn for each genus. In contrast to the taxodiaceous Cupressaceae, in Cupressoideae outgrowths of the seed-scale do not exist; the seed scale is completely reduced to the ovules, inserted in the axil of the cone scale. The cone scale represents the bract scale and is not a bract- /seed scale complex as is often postulated. Especially within the strongly derived groups of the Cupressoideae an increased number of ovules and the appearance of more than one row of ovules occurs. The ovules in a row develop centripetally. Each row represents one of ascending accessory shoots. Within a cone the ovules develop from proximal to distal. Within the Cupressoideae a distinct tendency can be observed shifting the fertile zone in distal parts of the cone by reducing sterile elements. In some of the most derived taxa the ovules are no longer (only) inserted axillary, but (additionally) terminal at the end of the cone axis or they alternate to the terminal cone scales (Microbiota, Tetraclinis, Juniperus). Such non-axillary ovules could be regarded as derived from axillary ones (Microbiota) or they develop directly from the apical meristem and represent elements of a terminal short-shoot (Tetraclinis, Juniperus). -

Ichthyofaunal Diversity of Jinari River in Goalpara
CIBTech Journal of Zoology ISSN: 2319–3883 (Online) Online International Journal Available at http://www.cibtech.org/cjz.htm 2020 Vol.9, pp.30-35/Borah and Das Research Article [Open Access] ICHTHYOFAUNAL DIVERSITY OF JINARI RIVER IN GOALPARA, ASSAM, INDIA Dhiraj Kumar Borah and *Jugabrat Das Department of Zoology, Goalpara College, Goalpara, Assam, India, *Author for Correspondence: [email protected] ABSTRACT The present study attempts to access the ichthyofaunal diversity of Jinari river in Goalpara district of Assam, India. There was no previous report on piscine diversity of this river in Assam. Survey was conducted in the lower stretch of the river in Goalpara district from April 2018 to March 2019. Fish specimens were collected from five pre-selected sites, preserved and identified adopting standard methods. A total of 74 fish species belonging to nine (9) orders, 26 families and 58 genera were recorded. Cypriniformes was the dominant order with 35 species followed by Siluriformes with 19 species. IUCN status shows two vulnerable, eight near threatened and 66 species under the least concern category. Prevalence of anthropogenic threats like garbage dispersal and agricultural pesticide flow to the river, setting of brick industries on the bank, poison fishing in the upper stretch etc. may affect the fish population in this river. In this regard, awareness is the need of the hour among the inhabitants of the surrounding villages. Keywords: Ichthyofauna, Jinari River, Goalpara, Brahmaputra River, Assam INTRODUCTION The Northeastern region of India is considered to be one of the hotspots of freshwater fish biodiversity in the world (Ramanujam et al., 2010). -
Characterization of Calcineurin a and B Genes in the Abalone, Haliotis Diversicolor, and Their Immune Response Role During Bacterial Infection
Characterization of calcineurin A and B genes in the abalone, Haliotis diversicolor, and their immune response role during bacterial infection Tiranan Buddawong1, Somluk Asuvapongpatana1, Saengchan Senapin2,3, Carmel McDougall4 and Wattana Weerachatyanukul1 1 Department of Anatomy, Faculty of Science, Mahidol University, Ratchathewi, Bangkok, Thailand 2 Center of Excellence for Shrimp Molecular Biology and Biotechnology (Centex Shrimp), Faculty of Science, Mahidol University, Ratchathewi, Bangkok, Thailand 3 National Center for Genetic Engineering and Biotechnology (BIOTEC), National Science and Technology Development Agency (NSTDA), Klongluang, Pathumthani, Thailand 4 Australian Rivers Institute, Griffith University, Nathan, Queensland, Australia ABSTRACT Calcineurin (CN) is known to be involved in many biological processes, particularly, the immune response mechanism in many invertebrates. In this study, we characterized both HcCNA and HcCNB genes in Haliotis diversicolor, documented their expression in many tissues, and discerned their function as immune responsive genes against Vibrio parahaemolyticus infection. Similar to other mollusk CNs, the HcCNA gene lacked a proline-rich domain and comprised only one isoform of its catalytic unit, in contrast to CNs found in mammals. HcCNB was highly conserved in both sequence and domain architecture. Quantitative PCR and in situ hybridization revealed that the genes were broadly expressed and were not restricted to tissues traditionally associated with immune function. Upon infection of H. diversicolor with V. parahaemolyticus (a bacteria that causes serious disease in crustaceans and mollusks), both HcCNA and HcCNB genes were highly up-regulated at the early phase of bacterial infection. HcCNB was expressed significantly higher than HcCNA in response to bacterial challenge, Submitted 12 November 2019 Accepted 9 March 2020 suggesting its independent or more rapid response to bacterial infection. -

Haque Department of Fisheries Management, Bangladesh Agricultural University, Mymensingh 2202, Bangladesh 1Ptresent address: Bangladesh Fisheries Research Institute, Riverine Station, Chandpur 3602 *Corresponding author Abstract Baseline survey and Participatory Rural Appraisal (PRA) during January 2003 to December 2004 on the fishing community revealed that unregulated fishing, use of destructive fishing gears, poaching of fishes, difficulties encountered in enforcing fisheries regulation and the helplessness of fishers to find alternative sources of income during banned fishing period (June to October) were the major management problems. CBFM (Community Based Fisheries Management) system as an alternative management strategy has been introduced to ensure active participation of the target group-the poor fishers living around the beet who were previously deprived to get access to the beet. Establishing a leasing system for controlled access, ensuring greater user-group participation through equitable distribution of all resource benefits among members, attempting to enforce penalties for illegal fishing linked with surprise checks to enforce management regulations are some of the recent steps taken by the BMC (Beet Management Committee). Chapila fish intake by the community was 31.25 g/head/day before stocking the beet by carp fingerlings. After stocking, they consumed chapila as fish protein from 8.33 g to 20.8 g/head/day during the fishing season (November to May) indicating that due to introduction of carp fingerlings, chapila production has been decreased in 2003-2004. -

Maintenance and conservation of Dipterocarp diversity in tropical forests _______________________________________________ Mohammad Nazrin B Abdul Malik A thesis submitted in partial fulfilment of the degree of Doctor of Philosophy Faculty of Science Department of Animal and Plant Sciences November 2019 1 i Thesis abstract Many theories and hypotheses have been developed to explain the maintenance of diversity in plant communities, particularly in hyperdiverse tropical forests. Maintenance of the composition and diversity of tropical forests is vital, especially species of high commercial value. I focus on the high value dipterocarp timber species of Malaysia and Borneo as these have been extensive logged owing to increased demands from global timber trade. In this thesis, I explore the drivers of diversity of this group, as well as the determinants of global abundance, conservation and timber value. The most widely supported hypothesis for explaining tropical diversity is the Janzen Connell hypothesis. I experimentally tested the key elements of this, namely density and distance dependence, in two dipterocarp species. The results showed that different species exhibited different density and distance dependence effects. To further test the strength of this hypothesis, I conducted a meta-analysis combining multiple studies across tropical and temperate study sites, and with many species tested. It revealed significant support for the Janzen- Connell predictions in terms of distance and density dependence. Using a phylogenetic comparative approach, I highlight how environmental adaptation affects dipterocarp distribution, and the relationships of plant traits with ecological factors and conservation status. This analysis showed that environmental and ecological factors are related to plant traits and highlights the need for dipterocarp conservation priorities. -
