Survey of Wild Animals in Market -Tuensang, Nagaland
Mongabay.com Open Access Journal - Tropical Conservation Science Vol.6 (2):241-253, 2013 Research Article Wildlife exploitation: a market survey in Nagaland, North-eastern India Subramanian Bhupathy1*, Selvaraj Ramesh Kumar1, Palanisamy Thirumalainathan1, Joothi Paramanandham1, and Chang Lemba2 1Sálim Ali Centre for Ornithology and Natural History Anaikatti (Post), Coimbatore- 641 108, Tamil Nadu, India 2C/o Moa Chang, Youth Secretary, Near Chang Baptist, Lashong, Thangnyen, Mission Compound, Tuensang, Nagaland, India *Corresponding Author ([email protected]) Abstract With growing human population, increased accessibility to remote forests and adoption of modern tools, hunting has become a severe global problem, particularly in Nagaland, a Northeast Indian state. While Indian wildlife laws prohibit hunting of virtually all large wild animals, in several parts of North-eastern parts of India that are dominated by indigenous tribal communities, these laws have largely been ineffective due to cultural traditions of hunting for meat, perceived medicinal and ritual value, and the community ownership of the forests. We report the quantity of wild animals sold at Tuensang town of Nagaland, based on weekly samples drawn from May 2009 to April 2010. Interviews were held with vendors on the availability of wild animals in forests belonging to them and methods used for hunting. The tribes of Chang, Yimchunger, Khiemungan, and Sangtam are involved in collection/ hunting and selling of animals in Tuensang. In addition to molluscs and amphibians, 1,870 birds (35 species) and 512 mammals (8 species) were found in the samples. We estimated that annually 13,067 birds and 3,567 mammals were sold in Tuensang market alone, which fetched about Indian Rupees ( ) 18.5 lakhs/ year. -

Chapter 4. Experimental Pollinations Within and Between Members of the Drosera Peltata Complex (Droseraceae)
Chapter 4. Experimental pollinations within and between members of the Drosera peltata complex (Droseraceae) 4.1 Introduction The study of plant breeding systems has taxonomic and evolutionary implications. Inter-taxon compatibility, measured by seed set following cross pollinations, has been used to define taxon limits. Individuals that are cross compatible and produce fertile offspring are considered to be conspecific, or belong to the same species, whereas those that do not are considered separate species. This is known as the biological species concept (Mayr and Ashlock 1991~ Mayr 1993). The phylogenetic species concept approach also defines taxa by their gene flow, and estimates evolutionary relationships between entities. It is considered that unimpeded gene flow occurs within species, but that reproductive barriers prevent gene flow between species (Mayr 1993). The nature and extent of these reproductive barriers are considered to be commensurate in scale to the evolutionary divergence between the taxa of interest (Nixon and Wheeler 1990). Reproductive isolation mechanisms may exist that prevent gene flow between indi vidual plants or plant populations. These mechanisms may operate prior to pollination, between pollination and fertilization or post-fertilisation (Levin 1971). For example, otherwise reproductively compatible taxa may grow allopatrically, or may be sympatric but with non-overlapping flowering seasons, which prevents gene flow. Sympatlic congeners may also have floral morphologies that allows access by some pollinators but not others, preventing heterospecific pollen transfer. Prezygotic reproductive barriers prevent heterospecific pollen from germinating on the stigmas, or chemically inhibit pollen tube growth in the style. Postzygotic reproductive barriers may occur so that hybrid zygotes fail to develop. -
Foraging Modes of Carnivorous Plants Aaron M
Israel Journal of Ecology & Evolution, 2020 http://dx.doi.org/10.1163/22244662-20191066 Foraging modes of carnivorous plants Aaron M. Ellison* Harvard Forest, Harvard University, 324 North Main Street, Petersham, Massachusetts, 01366, USA Abstract Carnivorous plants are pure sit-and-wait predators: they remain rooted to a single location and depend on the abundance and movement of their prey to obtain nutrients required for growth and reproduction. Yet carnivorous plants exhibit phenotypically plastic responses to prey availability that parallel those of non-carnivorous plants to changes in light levels or soil-nutrient concentrations. The latter have been considered to be foraging behaviors, but the former have not. Here, I review aspects of foraging theory that can be profitably applied to carnivorous plants considered as sit-and-wait predators. A discussion of different strategies by which carnivorous plants attract, capture, kill, and digest prey, and subsequently acquire nutrients from them suggests that optimal foraging theory can be applied to carnivorous plants as easily as it has been applied to animals. Carnivorous plants can vary their production, placement, and types of traps; switch between capturing nutrients from leaf-derived traps and roots; temporarily activate traps in response to external cues; or cease trap production altogether. Future research on foraging strategies by carnivorous plants will yield new insights into the physiology and ecology of what Darwin called “the most wonderful plants in the world”. At the same time, inclusion of carnivorous plants into models of animal foraging behavior could lead to the development of a more general and taxonomically inclusive foraging theory. -

Nandini Sundar
Interning Insurgent Populations: the buried histories of Indian Democracy Nandini Sundar Darzo (Mizoram) was one of the richest villages I have ever seen in this part of the world. There were ample stores of paddy, fowl and pigs. The villagers appeared well-fed and well-clad and most of them had some money in cash. We arrived in the village about ten in the morning. My orders were to get the villagers to collect whatever moveable property they could, and to set their own village on fire at seven in the evening. I also had orders to burn all the paddy and other grain that could not be carried away by the villagers to the new centre so as to keep food out of reach of the insurgents…. I somehow couldn’t do it. I called the Village Council President and told him that in three hours his men could hide all the excess paddy and other food grains in the caves and return for it after a few days under army escort. They concealed everything most efficiently. Night fell, and I had to persuade the villagers to come out and set fire to their homes. Nobody came out. Then I had to order my soldiers to enter every house and force the people out. Every man, woman and child who could walk came out with as much of his or her belongings and food as they could. But they wouldn’t set fire to their homes. Ultimately, I lit a torch myself and set fire to one of the houses. -

HEARN Department of Ecology and Evolutionary Biology, University of Arizona, Tucson, Arizona 85721, USA ([email protected]) ABSTRACT To understand evolutionary patterns and processes that account for anatomical diversity in relation to ecology and life form diversity, anatomy of storage roots and stems of the genus Adenia (Passifloraceae) were analyzed using an explicit phylogenetic context. Over 65,000 measurements are reported for 47 quantitative and qualitative traits from 58 species in the genus. Vestiges of lianous ancestry were apparent throughout the group, as treelets and lianous taxa alike share relatively short, often wide, vessel elements with simple, transverse perforation plates, and alternate lateral wall pitting; fibriform vessel elements, tracheids associated with vessels, and libriform fibers as additional tracheary elements; and well-developed axial parenchyma. Multiple cambial variants were observed, including anomalous parenchyma proliferation, anomalous vascular strands, successive cambia, and a novel type of intraxylary phloem. -

As a consequence of relying on non-renewable energy sources and reckless encroachment on natural habitats a lot of plant and animal species have become extinct and more and more species are getting endangered. Thus celebrating biodiversity and solidarity for all life forms, from the tiniest one to the most complex eco-systems, has been in the centre of our attention and operational activities. Keywords: durable development, ecology, endangered species. 1. Introduction Within the massive destruction of forests and forest climate, we witness significant changes, Just as the man has passed from the stage of sometimes radical of the environment. For the animal hunter and collector up to animal raiser and farmer, and plants which have survived through a long period the natural vegetation has increasingly been subject of adaptation, a new difficult era starts again. -

Outline of Angiosperm Phylogeny
Outline of angiosperm phylogeny: orders, families, and representative genera with emphasis on Oregon native plants Priscilla Spears December 2013 The following listing gives an introduction to the phylogenetic classification of the flowering plants that has emerged in recent decades, and which is based on nucleic acid sequences as well as morphological and developmental data. This listing emphasizes temperate families of the Northern Hemisphere and is meant as an overview with examples of Oregon native plants. It includes many exotic genera that are grown in Oregon as ornamentals plus other plants of interest worldwide. The genera that are Oregon natives are printed in a blue font. Genera that are exotics are shown in black, however genera in blue may also contain non-native species. Names separated by a slash are alternatives or else the nomenclature is in flux. When several genera have the same common name, the names are separated by commas. The order of the family names is from the linear listing of families in the APG III report. For further information, see the references on the last page.
