Steams: The Evolution of Life Histories () Life-history theory endeavours to increase our understanding of the processe,s whereby the broad features of the life cycles of organisms, such as the timing and magnitude of reproduction, have evolved. Although reproductive traits have dominated as study objects due to their immediate importance. The monotypic Eugomontia differs from the other genera in that both phases of the life history are shell-boring and multicellular. Phylogenetic analyses of ISS rDNA sequences from Collinsiella tuberculata, Eugomontia sacculata and Gomontia polyrhiza indicate that these species, together with Monostroma grevillei, form a distinct and well.

Life History Strategies. Among biological organisms, there is a continuum in life history strategies between what are referred to as r-selected species and k-selected history strategy is correlated with many aspects of an organism's reproductive strategy and life history, as well as with demographic variables such as generation time and life span, and population parameters such as. In total specimens of genus Tetropium were collected. We analyzed beetles, including specimens of T. castaneum and specimens of T. fuscum. On 49 beetles (%) there were individuals of Trichouropoda shcherbakae (Trematuridae). Mites were more common on T. fuscum, which carried 82% of all collected deutonymphs.

Consequently, oxysperma, unrecorded for the American tropics may have previously been included in some of the Monostroma records. Culture studies were undertaken on from Cen tral America to compare the life history morphology of this material with . Marine macroalgae are a suitable source of ingredients due to their huge diversity, availability and nutritional and chemical composition. Their high content in proteins, carbohydrates and vitamins, but also in secondary metabolites such as phenolic compounds, terpenoids or pigments, make them great candidates for industrial applications. The cosmetic industry is one of the biggest in the.

Monostroma nitidum shares similar life history with M. latissimum, but differs only in thallus ontogeny in which the former produces a sac which breaks open to form the monostromatic blade (filament-sac-blade) while the latter produces erect filament that develops into monostromatic blade without tube or sac phases (filament-blade).Cited by: 5.

LIFE HISTORY STUDIES IN MONOSTROMA FUSCUM (POST. AND RUPR.) WITTR, INTRODUCTION The author's interest in the genus Monostroma was aroused while engaged in cultural studies of marine algae with Dr. Scagel at Friday Harbor, Washington during the summer of At that time, Dr.

In the ulvophycean alga Monostroma angicava, little is known about mitosis, including the number of chromosomes involved. angicava has a heteromorphic haplo-diplontic life cycle with a multicellular haploid gametophyte and a unicellular diploid sporophyte (Tatewaki ; Horinouchi et al.

Monostroma latissimum (Kuetzing) Wittrock is a monostromatic green alga of commercial importance in Japan. Here we report the serendipitous discovery of asexually reproducing specimens collected from Usa, on the Pacific coast of Kochi Prefecture, south-western Japan.

Zoids were found to be biflagellate and negatively phototactic. Germination of settled zoids was observed to follow. Life-history is a method of qualitative research, frequently, but not exclusively, used in anthropology and in the health sciences provides an alternative to empirical methods for identifying and documenting health patterns of individuals and groups.

Key message. Within-clutch gamete size variability in Monostroma angicava. Abstract. In many organisms, it is unclear how the size variation in gametes is generated in each clutch (i.e., total gametes produced by a gametophyte for a single spawning) or how gamete size is adjusted.

The specimen of Monostroma oxyspermum (Chlorophyceae) were collected in Indian waters from mangrove ecosystem of Shirgao Creek, Ratnagiri, Maharashtra; Terekhol Creek, Goa; and Kali Estuary, Karwar Karnataka.

The life history of these were studied. Alternate reproduction was not found to be taking place in this species. In this paper, we present our findings on the life-history studies of bloom-forming U. prolifera in the YS, using four strains of U.

prolifera isolated from the YS. The potential role of the life-history characteristics of U. prolifera in the formation of green tides is also discussed.

The challenge for evolutionary biology is to explain how such diversity arises. The Evolution of Life Histories does this by showing that natural selection is the principal underlying force molding life history variation.
