The primary objective of this study was to test the relevance of hydrological classification and class differences to the characteristics of woody riparian vegetation in a subtropical landscape in Queensland, Australia. We followed classification procedures of the environmental flow framework ELOHA - Ecological Limits of Hydrologic Alteration. Riparian surveys at 44 sites distributed across fiv...

The Mediterranean fruit fly Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) is one of the principal exotic pests affecting Brazilian production in the northeastern and southeastern regions of Brazil. In the south, it is has potential as a serious threat to temperate-climate fruit farms, since it is already found in urban and suburban communities in this region. We studied the biological c...

Forest ecosystems make a greater contribution to carbon (C) stocks than any other terrestrial ecosystem. To understand the role of regional forest ecosystems in global climate change and carbon exchange, forest C stocks and their spatial distribution within the small (2300 km2) Liuxihe River basin in China were analyzed to determine the different contributors to the C stocks. Forest C stocks we...

Ocean warming is already affecting global fisheries with an increasing dominance of catches of warmer water species at higher latitudes and lower catches of tropical and subtropical species in the tropics. Tuna distributions are highly conditioned by sea temperature, for this reason and their worldwide distribution, their populations may be a good indicator of the effect of climate change on gl...

Observational analysis suggests that the western tropical Pacific (WTP) sea surface temperature (SST) shows predominant variability over multidecadal time scales, which is unlikely to be explained by the Interdecadal Pacific Oscillation. Here we show that this variability is largely explained by the remote Atlantic multidecadal oscillation (AMO). A suite of Atlantic Pacemaker experiments succes...

Satellite remotely-sensed sea surface temperature (SST) and surface chlorophyll were used to estimate median phytoplankton cell size at monthly and 11 km resolution over the global ocean, 1998–2007. The temporal dynamics of median phytoplankton cell size were examined for the Pacific equatorial upwelling region and the subtropical oceans. For the equatorial upwelling region, cell size varied co...

Significant climate anomalies persist through the summer (June-August) after El Nino dissipates in spring over the equatorial Pacific. They include the tropical Indian Ocean (TIO) sea surface temperature (SST) warming, increased tropical tropospheric temperature, an anomalous anticyclone over the subtropical Northwest Pacific, and increased Meiyu-Baiu rainfall over East Asia. The cause of these...

Epidemiological studies of the relationship between climate and the onset of aneurysmal subarachnoid hemorrhage (SAH) have been reported in the temperate and subarctic latitudes. However, the relationship between the incidence of aneurysmal SAH and the climatic variations in the subtropical region remains uncertain. Epidemiological analysis requires study of an extremely isolated area. This stu...

introduction: toxoplasma gondii is one of the most important foodborne pathogens. toxoplasmosis causes abortion and neonatal loss in livestock and imposes significant losses to farming industry. prevalence of t. gondii in sheep and goats was investigated in three adjacent geographical areas within gilan province in north of iran. methods: serum samples were collected from 247 sheep and 155 goat...

Background Low-cost methods to mitigate the increasing levels of carbon dioxide in the atmosphere and their implications on global climate change have received considerable attention in the last years [1,2]. Afforestation is an important alternative to reduce the rise in atmospheric CO2 concentration due to the system’s ability to fix carbon in forest biomass and soil [3]. Several studies have ...
