Similar results were found for tropical silvopastoral systems where the canopy cover and tree density were positively related with migratory bird flocks . In a comparison of different structural complexity, silvopastoral systems supported less diverse bird flocks than shade coffee in Colombia, but it is likely that shade coffee could support more bird species than …

The cost is that it may measure something different from the impact of climate on long-run profit
One possible measure is farmland value, which presumably reflects long run profitability, and which has been used quite extensively since Mendelsohn et al. introduced the so-called Ricardian approach for assessing the impact of climate change on agriculture. With this approach, one estimates a Ricardian or hedonic regression relating farmland value to climate variables and to other …
The main impact on MA changes during this sample period was from output demand
Even based on observed pK changes, CMA,pK=0.044. If weighted by the greater increases p*K, the MA demand augmenting impact of capital price changes would be C*MA,pK =0.056. The implied higher growth of virtual compared to measured price of capital could result from various factors. Its drivers could include substantive and rising adjustment costs , environmental or …

Pasture still accounts for over 90 percent of animal nutrition in Brazil
In the piece, Boyd describes a heterogeneous network of firms, governments, and advocates developing REDD institutions simultaneously. He uses the metaphor of DNA to describe how frameworks and approaches from any particular effort can be combined and recombined into other efforts without passing through the bureaucracy of the UN. One respondent noted that a good …

Fitz-Gibbon and Eisler similarly critiqued early meta-analyses of educational and psychology studies
In contrast to the notion that seepage water from wetlands may be considered as a source of groundwater nitrate contamination, this study shows that under the conditions present in our wetland, seepage through wetland soils can actually prevent some nitrate contamination of groundwater. Before recommending constructed wetlands that utilize seepage as a beneficial-management practice for …
An increase in government spending naturally affects domestic aggregate demand
The devaluing pressure on the exchange rate would create an interest differential in favor of the foreign countries and a capital outflow which would increase the depreciating pressure on the exchange rate. Money supply growth would thus decrease proportionally and so would price inflation, at least initially. Real depreciation would then lead to an increase …

Our findings show that PFAS exposure dysregulates adipogenesis
Barrier disruptions were attributed to the toxic effects of PFOS on f-actin, microtubule, and gap junction organization. Specifically, dose dependent PFOS exposure disassembled tight and gap junctions responsible for barrier function of blood-testis barrier, increased blood-testis barrier permeability, and disrupted spermatogenesis. PFAS chemicals have also demonstrated tight junction opening in brain endothelial cells, a main …

Cell densities can be optimized for specific cells and research question
Anatomically, skin is the largest organ in the human body and is made up of three main layers and possesses a complex system of stromal, vascular, glandular, and immune/nervous system components in addition to epidermal cells. The epidermis itself is composed of four layers of cells that are continuously renewed to maintain barrier function and other …

The short wavelength of soft X-rays enabled high-resolution 3D imaging of the nuclear architecture
The 800 m transient data provides slight improvements in precipitation estimates for the state, particularly at high elevations dominated by snow pack. For future projections, a broader suite of GCM and scenarios could be developed, while awaiting the next iteration of projections from the IPCC. To improve the snow‐driven module in BCM, calibration of the …
Carbon is one of the most abundantly available elements on earth
Natalia Molina traces the relationship between public health in Los Angeles and compares the experiences of Chinese to that of Japanese and Mexican residents in the city in the period between 1879-1939.Taken together these works remind us that Chinatown was only one of the many districts that composed Los Angeles’s core in the first half …
