Nitula baltica sp. nov. and Cyathus dominicanus sp. nov. are described from Cenozoic Baltic and Dominican amber. These are the first fossil members of the Family Nidulariaceae and show that the basic characteristics of this group were already established some 40-50 million years ago.
Solution deposition offers an attractive, low temperature option in the cost effective production of thin film solar cells. Continuous microreactor-assisted solution deposition (MASD) was used to produce nanocrystalline cadmium sulfide (CdS) films on fluorine doped tin oxide (FTO) coated glass substrates with excellent uniformity. We report a novel liquid coating...
Background: Pinnipeds, including many endangered and declining species, are inaccessible and
difficult to monitor for extended periods using externally attached telemetry devices that are shed
during the annual molt. Archival satellite transmitters were implanted intraperitoneally into four
rehabilitated California sea lions (Zalophus californianus) and 15 wild juvenile Steller sea lions...
Pacific cod (Gadus macrocephalus) is an economically and ecologically important species in the southeastern
Bering Sea and Aleutian Islands, yet little is known about the spawning dynamics of Pacific cod in
these regions. To address this knowledge gap, we applied a gross anatomical maturity key for Pacific cod
to describe...
Seabirds have often been proposed as environmental indicators. Beached bird data may provide an additional data source and such data is efficacious because it can reliably be collected by volunteers. In addition to anthropogenic factors, such as oil spills, changes in the ocean-atmosphere can affect carcass beaching rate in 3...
The future of agricultural research depends on data. The sheer volume of agricultural biological data being produced today makes excellent data management essential. Governmental agencies, publishers and science funders require datamanagement plans for publicly funded research. Furthermore, the value of data increases exponentially when they are properly stored, described, integrated...
Science has a critical role to play in guiding more sustainable development trajectories. Here, we present the Sustainable Amazon Network (Rede Amazonia Sustentavel, RAS): a multidisciplinary research initiative involving more than 30 partner organizations working to assess both social and ecological dimensions of land-use sustainability in eastern Brazilian Amazonia. The...
In a previous article, Beschta et al. (Environ
Manag 51(2):474–491, 2013) argue that grazing by large
ungulates (both native and domestic) should be eliminated
or greatly reduced on western public lands to reduce
potential climate change impacts. The authors did not
present a balanced synthesis of the scientific literature, and...
Landscape and site-scale data analyses aid
the interpretation of biological data and thereby help
us develop more cost-effective natural resource management
strategies. Our study focused on environmental
influences on stream assemblages and we
evaluated how three classes of environmental variables
(geophysical landscape, land use and cover, and
site habitat), influence...
The effect of fluid axial thermal conduction on one-dimensional liquid metal natural circulation and its linear stability was performed through nondimensional analysis, steady-state assessment, and linear perturbation evaluation. The Nyquist criterion and a root-search method were employed to find the linear stability boundary of both forward and backward circulations. The...
