The study was carried out from May 1988 to April 1993 in two types of tropical forests: the tropical evergreen and moist deciduous. The vertical distribution of birds and foliage abundance was recorded by visual observation in seven height classes, using the line transect method. The vertical distribution of 94 bird species was recorded in evergreen forest, and of 90 in moist deciduous forest. Bird species richness and the numbers of birds were highest in the stratum from 1 to 5 m in both the evergreen forests (57 species) and the moist deciduous forests (68 species). The species richness indices of birds in the two types of forest did not display such a clear relationship. Foliage abundance was high up to a height of 30 m in the evergreen forests, whereas in moist deciduous forests, foliage was abundant only up to 20 m. A significant positive correlation was obtained between foliage abundance and species richness and also between the numbers of birds in both types of forests. Significant correlation was also obtained between foliage abundance and the species diversity indices in the two types of vegetation.

The present study was undertaken to identify the superior cabbage genotype and to examine their physical yield performance among the four cultivated genotypes namely Namdhari Seeds 183, Namdhari Seeds 160, Namdhari Seeds 35 and Tropical Sun Plus, grown in plains and higher altitude of Kerala. Study revealed that significant differences were observed in yield levels of cabbage and it was ranged from 22.6 – 29.3 kg /16m2 in hills and 1.27 – 22.06 kg /16m2 in plains. Among the cabbage genotypes, NS 183 was found to be the best for hilly region in terms of higher head yield (22.06 Kg /16m2), head weight (729.6 g), head height (11.1 cm) and early maturity. Similarly, Tropical Sun Plus exhibited better performance in plains in terms of higher head yield (22.06 Kg /16m2), head weight (729.6 g) and head height (11.1 cm). The individual genotype which exhibited the superior performance in hills and plains were selected and compared for the general biochemical characters like Moisture content, acidity, ascorbic acid, protein, phosphorus, calcium and potassium. Finally, the study found that, the genotype grown at hill (Tropical Sun Plus) was recorded a higher biochemical characters than genotype grown in plains (Tropical Sun plus). Similarly, hill grown genotype (NS 183) recorded a higher biochemical characters than the plains grown genotype (NS 183).

Cauliflower is grown in all the agro climatic zones of India, accounting for an area of 3.9 lakh hectares with production of 73.4 lakh tones. Hence, studies are to be undertaken to identify genotype and analyze the physical characteristics among the cultivated genotypes (Namdhari Seeds 60 N, Namdhari Seeds 133, Pusa Meghna and Basant) grown under hills and plains of Kerala, India. In this study, significant differences were observed in yield of cauliflower which ranged from 21 – 26.4 kg /16 m2 in hills and 0.78 – 1.43 kg /16 m2 in plains. Among the cauliflower genotypes, NS 133 was found to be the best for hilly region in early yield and yield attributes. The cauliflower genotype NS 133 exhibited better performance in hills in terms of high curd yield (26.4 Kg /16 m2), curd weight (800 g) and curd height (13.93 cm). In general, harvest maturity was delayed by 39 – 45 days in the plains as compared to higher altitudes. The cauliflower genotypes which exhibited superior performance in hills and plains were selected for further sensory evaluation studies. In this study cauliflower genotype NS 60N recorded superior organoleptic qualities when grown in plains than hilly region. However in the case of genotype NS 133, the differences in sensory qualities between produce from hills and plains were not significant.

Two species of parasitic nematodes, Heliconema ahiri Karve, 1941 (Physalopteridae) and Procamallanus (Spirocamallanus) anguillae Moravec et al., 2006 (Camallanidae), were recorded from the Indonesian shortfin eel Anguilla bicolor bicolor Mc-Clelland in the Chalakkudi River and Veli Lake, respectively, both Kerala, India. The former species (H. ahiri), rediscovered from eels in India after 82 years from its original description, has been redescribed and revalidated based on its specific feature (presence of groups of minute denticles in the mouth) distinguishing it from other congeners; its finding in A. b. bicolor represents a new host record. The latter species (P. anguillae) has been recorded in India for the first time. SEM examination of its first-stage larvae from uterus has shown that P. anguillae is another species of Procamallanus whose larvae possess a crown of digit-like processes at the tail tip.

The weight–length (W–L) relation was estimated for an endemic catfish, Horabagrus brachysoma (known also as Asian sun catfish, Günther’s catfish, Manjaletta, or Manjakoori). The fish were collected from the four major river systems of Kerala, part of the Western Ghats mountain range, between January 2005 and February 2006. The estimates for the parameter b of the W–L relation (W = aLb) ranged between 2.7623 and 3.17968. Linear regressions on log- transformed data were highly significant (P < 0.01) for the species in all the riverine habitats studied. Analysis of covariance revealed significant difference between sexes of H. brachysoma in the Chalakudy River for the slopes of the regression line.

The life-cycle stages of a new species of Uvulifer, U. iruvettiensis sp. nov. infecting the white-throated kingfisher Halcyon smyrnensis (Linnaeus) in Kerala, India are described. The new species is described in detail, and compared with its related species. The furcocercous cercariae emerged from the planorbid snail Indoplanorbis exustus (Deshayes). Metacercariae were found below the skin of tadpoles of Euphlyctis cyanophlyctis (Schneider). H. smyrnensis became infected when fed on tadpoles containing infective metacercariae. Pre-patent period is 10 days. Successive stages in the development of metacercariae and adults were followed in the laboratory.

Background. The longnose seahorse, Hippocampus trimaculatus Leach, 1814, included in the Red List of Threatened Species is the most common and least studied seahorse species along the south-west coast of India. Practically no information is available on numerical taxonomy and sexual dimorphism of H. trimaculatus from India. The purpose of the reported study is to describe the morphometry and meristics of H. trimaculatus occurring along Kerala, south-west coast of India. Materials and Methods. A total of 45 specimens of H. trimaculatus, represented by 25 males and 20 females, obtained from trawl by-catch, were studied following standard morphometric and meristics procedures. Statistical data analyses include Student’s t-test, Mann–Whitney U test, and Principal Component Analysis to describe the sexual dimorphism of the species. Results. Male H. trimaculatus are longer than females, with relatively longer tails. The mean values of head depth, snout depth, trunk depth, trunk width, dorsal fin base length, and pectoral fin base length are higher in males, while head length, snout length, coronet height, and trunk length are higher in females. Trunk length and snout depth are the two principal components that determine sexual dimorphism in H. trimaculatus. Conclusion. The numerical taxonomy of H. trimaculatus from Indian coastal waters is reported for the first time. The study shows that sexual dimorphism in H. trimaculatus is reflected in differing morphometric characters between the sexes.
