The growth of colonies in semisolid medium is receiving wide spread attention as a possible test for predicting the clinical response of individual human tumors to specific drugs. One problem encountered in these studies is the difficulty of preparing single-cell suspensions from solid tumors. Often, microscopic examination of the cultures just after plating reveals many clus ters or clumps of ...

The practice of renewing and restoring degraded, damaged, or destroyed ecosystems and habitats in the environment by active human intervention and action. However, the effectiveness of restoration actions in increasing provision of both biodiversity and ecosystem services have not been evaluated systematically. A meta-analysis of 20 restoration assessments in a wide range of ecosystem types acr...

Fully-protected marine reserves can function at several spatial scales, from a single area encompassing few habitats, to local networks of many habitats, to large-scale networks connected by larval dispersal. However, the amount, spatial distribution, and associated administrative attributes of Caribbean marine reserves are collectively unknown. We compiled information on reserves from 21 count...

Wetlands created within disturbed landscapes may be an important key to restoring lost ecosystem functions. Reclaimed mines provide opportunity create wetlands and restore natural features a landscape while benefiting amphibians, taxa affected by habitat loss. A large-scale restoration effort the Monongahela National Forest, West Virginia, USA has resulted in creation of over 1400 small wetland...

Coastal waters provide an important spawning and nursery ground for offshore marine organisms. To understand the suitable habitat distribution of Harpadon nehereus , a key nearshore species, this study assessed survey data fishery resources environment in Zhejiang’s Spring 2017 to 2020. We used generalized additive model (GAM) random forests (RF) analyze environmental factors affecting selectio...

Members of the oyster family Chamidae are common in Indo-Pacific subtidal habitats, adhering to the sides of rocks, where they are usually well hidden by a fine growth of algae that extends equally over the rocks and the oyster shells (Purchon 1968). Chamidae species are known for their efficient filter-feeding abilities and thus may compete with other benthic filter-feeders for both space and ...

Escalation in number of resistant pathogens and diseases enhanced scientists to explore the unconventional habitats for bioactive compounds. Marine microorganisms represent a promising source for natural products due to the incredible diversity of chemical compounds that were isolated. Due to distinctive features and biodiversity of Red Sea biota, it was selected as a resource for isolation of ...

We evaluated the impact of marine materials on the diet and abundance of arthropodivorous lizards inhabiting islands and the coast of the Gulf of California. Here, marine materials are brought onto land by seabirds and by tidal action, and both subsidy pathways cause arthropod abundance to increase. We evaluated Uta stansburiana (side-blotched lizard) diets in three habitats defined by having: ...
