Última History of the landscape of Obihiro city before modern development OAK 橋本, 靖; 佐藤, 雅俊; 赤坂, 卓美. 　自然環境や生物多様性保全の必要性への認識の高まりから，近年，人為的な緑地造成が行われる機会が増えている。その際，対象地本来の自然景観を参考にすることは，より目的に叶った緑地の造成につながりやすいと考えられる。そこで，帯広市周辺の本来の自然景観を推測するために，明治期の開拓以前の状況を，様々な文献を参考にして考察した。有名な江戸後期の十勝日誌等の記述からは，この地域に広い草原地帯があったことがうかがわれ，また，開拓期の様々な記録からも広い草原の存在が示された。また，黒ボク土の分布との関係からは，本地域での広い草原の存在と，野火の発生の歴史が想定された。このように，開拓前の帯広市周辺は，一面が原生的な森林に被われていたわけでなく，その平野部の広大な河川敷は，主に草原に被われていたものと推測された。そのため，帯広市の平野部において緑地の再生を考える際，森林環境だけではなく，湿性の草原や疎林のような環境も，再生するべき緑地景観の候補として，考えに入れる必要があると考えられる。 Palavras-chave: 帯広市; 開拓; 河川敷; 黒ボク土; 湿地; 森林; 草原; 十勝川; 氾濫原; 野火; Andosols; Floodplain; Grassland; Marsh; Obihiro city; Tokachi River; Wildfire.

The hedonic valuation method (HVM) was used to quantify the impact of the threat of flooding on housing values in Fargo, North Dakota and Moorhead, Minnesota (Fargo-Moorhead). Prices of 3,783 Fargo-Moorhead homes sold between 1995 and 1998 were regressed against structural housing characteristics, neighborhood and environmental indicators, and three flood risk variables. Being located in the 100-year floodplain lowered the sale price of an average home by $8,990 and approximately 81 percent of the price depreciation was associated with required flood insurance premiums. After the extensive 1997 flood, homes in the 100-year floodplain were on average priced $10,241 less than similar homes located outside the floodplain and before the 1997 flood event....

CATTANIO,JOSÉ H.; ANDERSON,ANTHONY B.; CARVALHO,MANOEL S.. Slight topographic variations appear to exert dramatic effects on the structure of forests subject to inundation. In a late successional tidal floodplain forest near the Amazon port of Belém, Brazil, we examined these effects by studying floristic composition along a topographic gradient. We predicted that, relative to high sites, low sites would be characterized by high representation of life forms and taxa characteristic of inundated sites. We found striking variations in floristic composition along a slight topographic gradient. In comparison with topographically high sites, low sites were characterized by a high representation of Palm trees (Arecaceae), low diversity of trees and lianas, and high plant density. These variations appear to reflect... Tipo: Info:eu-repo/semantics/article Palavras-chave: Floodplain; Floristic; Forest; Topography; Várzea.

Bras. Zool. Costa,Igor David; Freitas,Carlos Edwar de Carvalho. ABSTRACT Determining the significance of biotic and abiotic factors in the structuring of fish assemblages in freshwater environments is an important question in ecology, particularly in view of environmental changes caused by man. In this paper we sought to identify the factors responsible for the composition and abundance of fish species collected with gill nets in six locations near ports in forest clearance areas opened up for oil and natural gas exploration (Petrobras Pedro Moura Base) in the Urucu River, during drought and flood cycles. In all, 923 individuals from 23 families and 82 species were collected, totalling a biomass of 182,244 g. The most abundant species during the flood season were Bryconops alburnoides (Kner, 1858) and Dianema...

The Bananal Island is regarded the largest fluvial island in the world, bounded by Araguaia and Javaés rivers, being located in southwest of Tocantins. The objectives of this work were to provide information about the vegetational changes that occurred at the Bananal Island, in order to contribute to the understanding the dynamics of past and current savanna and areas of ecotones with forests. Thus, a sedimentary core collected from a small lake at the Bananal Island plain was submitted to pollen and radiocarbon dating analyses. The results showed that the last millennium was dominated by forest reflecting a wet climate. At the beginning of the record (920-770 yr cal BP) the wet climate and high rainfall produced flooding during long rainy seasons that...

In Amazonian floodplains the trees are exposed to extreme flooding of up to 230 days a year. Waterlogging of the roots and stems affects growth and metabolic activity of the trees. An increased leaf fall in the aquatic period and annual increment rings in the wood indicate periodical growth reductions. The present study aims at documenting seasonal changes of metabolism and vitality of adult trees in the annual cycle as expressed by changes of leaf nitrogen content. Leaves of six tree species common in floodplains in Central Amazonia and typical representants of different growth strategies were collected every month between May 1994 and June 1995 in the vicinity of Manaus, Brazil. Mean leaf nitrogen content varied between 1.3% and 3.2% in the non-flooded...

ABSTRACT The flood pulse of black water rivers in the Amazon basin determines the composition of species along the flood gradient in igapó forests. The Balbina dam, built on the Uatumã River, has altered the flood pulse and caused changes in the floristic composition of adult trees throughout the downstream area. There is a lack of studies on how communities of seedlings in igapó forests respond to changes in the flood pulse. This study investigates the response of seedling communities in the igapó forest downstream the Balbina dam and compares it with two pristine areas. The areas were sampled with transects of 1x25 m within 36 plots (25x25 m) along the flood gradient. Richness and dominance were calculated by simple regression and ordination analyses....
