Habitat fragmentation reduces genetic diversity and connectivity among toad populations in the Brazilian Atlantic Coastal Forest

Tropical rainforests are becoming increasingly fragmented and understanding the genetic consequences of fragmentation is crucial for conservation of their flora and fauna. [1]

SEA‐LEVEL RISE AND COASTAL FOREST RETREAT ON THE WEST COAST OF FLORIDA, USA

We investigated patterns, rates, and mechanisms of forest replacement by salt marsh in relation to sea‐level rise on the west coast of Florida, USA. The geomorphology of this region typifies that of low‐lying, limestone coastlines considered highly susceptible to sea‐level rise (e.g., much of the eastern Gulf of Mexico, the Yucatan Peninsula, and low‐lying limestone islands throughout the world). This coast is microtidal, shallowly sloping, and has a rate of relative sea‐level rise similar to that of eustatic rise. [2]

Frequency of movements of small mammals among Atlantic Coastal Forest fragments in Brazil

Rates of interfragment movements were estimated for small mammals inhabiting a group of eight Atlantic Coastal Forest fragments, surrounded by grassland matrix, in order to understand the degree to which each species’ population was isolated. [3]

Evaluation of Soil Fertility Status Based on CEC and Variation across Disturbed and Intact Tropical Coastal Forests Sites in Tanzania

Aims: Although an understanding of different levels of soil calcium, magnesium, potassium, sodium, cation exchange capacity, and percentage base saturation, is important in the management of forest ecosystems; however, there is limited documentation on the status of these elements in forest subjected to crop-agriculture and livestock grazing disturbances in the tropical coastal forests. This study aimed to evaluate soil fertility based on exchangeable bases’ status and variation across closed forest (control), agriculture and livestock disturbed sites in the coastal zone of Tanzania to add knowledge on the management of tropical coastal forests. Methodology: Systematic sampling and stratification approaches were used to get representative samples of forested blocks and disturbed sites. Forty-seven (50 m x 50 m) sampling plots on each of the forest sites were established in the study area from which 141 soil samples were drawn. Ammonium acetate solution was used to extract exchangeable calcium, potassium, magnesium [4]

Status of Restricted-Range Bird Species of East African Coastal Forests in Five South Coast Forest of Kenya

Aims: The aim of this study was to determine the status of restricted-range bird species of East African coastal biome, particularly within the Southern coastal forests of Kenya and as a proxy of the conservation value of the current existing fragmented forests. [5]
