Management Plan of the Ring-Tailed lemurs (Lemur catta) at Beza Mahafaly Special Reserve in Madagascar

Tue, 05/03/2016 - 11:29
Abstract: The need to protect Ring-tailed lemurs is evident. Lemurs are the most threatened group of vertebrates in the world with the IUCN listing 94% of lemur species as threated. This high percentage is in part due to the fact that lemurs only occur naturally in Madagascar so changes to the island effects the whole infraorder (Lemuriformes). Helping to curb illegal activities will protect not just the habitat for Ring-Tailed lemurs but will help the entirety of Madagascar’s Wildlife that has evolved on an island that used to be covered by up to 90% forest. These illegal practices are often protected by armed guards which may require assistance from the Madagascar government for adequate protection of the islands forests

Forest Succession's Effect on Soil Physical and Chemical Properties after Agriculture Abandonment

Mon, 12/01/2014 - 11:00
Abstract: Landscapes have been significantly altered by humans and replacing forests with agricultural crops is a major alteration humans have made. This landscape change has affected soils significantly. Agriculture practices can potentially have detrimental effects on soils. However, through the 20th century forest cover drastically increased in the United States through the recruitment of second growth forests as a result of agriculture abandonment. Forests reclaiming farm lands through forest succession can have a significant effect on recoveries in soil physical and chemical properties such as bulk density, soil strength, porosity and fertility. Therefore, the goal of this study was to investigate forest successions effect on soil physical and chemical properties after agriculture abandonment. Three specific hypotheses were tested: 1) Bulk density and soil strength will decrease while micro and macro porosity will increase as forests reclaim farm lands. 2) Soil carbon and available nitrogen will increase over time. 3) Soil pH will decrease and electrical conductivity will increase over time. These hypotheses were explored on abandoned agriculture fields in a chronosequence study on coarse loamy Inceptisols in upstate New York across a 60 year temporal scale. Data showed that total porosity, total carbon and available nitrogen increase while soil pH, bulk density, soil strength and electrical conductivity decline over time. These results support all three hypotheses except for the latter half of hypothesis number three. The findings of this study suggest that although agriculture may disturb soil properties, time coupled with forest succession can result in significant recoveries.
