We quantified species diversity of birds in mangroves at kundapura from April-2010 to March-2013. We recorded 79 species of 36 families and 14 orders. Of these 71% are resident species, 22% are residential migrants and 8% are migratory. One endangered species, three near threatened species, and a few occasional visitors were re-corded. Species diversity and abundance of birds were greater during from October through May as there was availability of food, increased vegetation and the arrival of migratory birds. Minimum diversity was recorded from June through September owing to heavy rains, increased flow of water, limited availability of food and return of migratory birds.

In open-ended piles, inner friction is developed between inner pile shaf and the inner soil. Inner frictional resistance depends largely on the degree of soil plugging, which is influenced by many factors including pile diameter, relative density and end conditions of piles. In this paper, effects of inner sleeves on inner frictional resistance are discussed. The experiments were conducted on a medium-dense sandy ground using laboratory-scale piles. It was observed that the piles penetrated under partially-plugged or unplugged state. The results suggest that inner fiictional resistance, Qin increases with sleeve height, l linearly and requires 2D （D is pile outer diameter） of l to produce a large as 50% of Qt by Qin （Qt is total resistance）. The results also indicate that bearing capacity increases with wall thickness at the pile tip, which can be attributed to the increase in annular area. The results also indicate that soil plug height is independent of sleeve height. The results also reveal that the penetration of straight piles is closer to unplugged state than the sleeved piles. The results of incremental filling ratio and plug length ratio also indicate that the degree of soil plugging is affected by the sleeve height.

Lentil(Lens culinaris Medik) is one of the most important food legumes in the world. The use in lentil of molecular marker-assisted breeding is limited, owing to the low availability of polymorphic markers. In the present study, we developed a set of polymorphic intron-spanning markers(ISMs) using a cross-species mapping approach. In this approach, putative unique transcripts(PUTs) of L. culinaris were mapped onto the Medicago truncatula genome, exploiting its closeness with the lentil genome. Spliced alignment of the PUTs resulted in a total of 25,717 alignments, allowing the development of 1703 ISMs. From these, a subset of 105 ISMs were synthesized and validated with a 51% amplification success rate in 32 lentil genotypes. Of these ISMs, 40(74%) were polymorphic and generated 2–11 alleles per locus in a genetically diverse panel of 32 lentil genotypes including wild *** set of polymorphic ISMs along with their functional annotation data will be useful in lentil breeding.
