Conditions favoring population divergence in trophic features, such as the low levels of species richness and interspecific competition found on islands, can be similar to conditions that increase their sexual dimorphism or overall variance. Male emberizid sparrows of tidal marshes have undergone parallel evolution of large bills. We tested for parallel increases between dimorphism and overall ...

BACKGROUND Dysmotility-like dyspepsia symptoms are frequent in patients with gluten-sensitive enteropathy (GSE). Current data suggest that patients with mild enteropathy may be present with gluten-sensitive symptoms and complications. AIM To investigate the prevalence of GSE, including mild enteropathy, in patients with dysmotility-like dyspepsia symptoms. METHODS We retrospectively studied...

We experimentally examined plant zonation in a previously unstudied Chilean salt marsh system to test the generality of mechanisms generating zonation of plants across intertidal stress gradients. Vertical zonation in this system is striking. The low-lying clonal succulent, Sarcocornia fruticosa, dominates the daily flooded low marsh, while intermediate elevations are dominated by the much tall...

Heterotrophic bacteria and fungi are widely recognized as crucial mediators of carbon, nutrient, and energy flow in ecosystems, yet information on their total annual production in benthic habitats is lacking. To assess the significance of annual microbial production in a structurally complex system, we measured production rates of bacteria and fungi over an annual cycle in four aerobic habitats...

Olson, Storrs L., and David C. Parris. The Cretaceous Birds of New Jersey. Smithsonian Contributions to Paleobiology, number 63, 22 pages, 11 figures, 1987.•^This is a revision of the fossil birds from Late Cretaceous (Maastrichtian; Hornerstown and Navesink formations) deposits in New Jersey. Material of previously named taxa, described over a century ago, is augmented by more recently collect...

Background: Tidal marshes will be threatened by increasing rates of sea-level rise (SLR) over the next century. Managers seek guidance on whether existing and restored marshes will be resilient under a range of potential future conditions, and on prioritizing marsh restoration and conservation activities. Methodology: Building upon established models, we developed a hybrid approach that involve...

Central aspects of carbon and sulfur biogeochemistry were studied along a transect extending from an unvegetated mudflat into a Spartina anglica salt marsh. Conditions along the transect differed with respect to tidal elevation, sediment characteristics, vegetation coverage, and benthic macrofauna abundance. Dark sediment O2 uptake and CO2 emission at the highly bioturbated mudflat were low and...

کمتر اتفاق می افتد که داوران مختلف در داوریهای خود حتی نسبت به یک امر واحد مجموعه یکسانی به دست دهند. اگر مجموعه نمره های دو داور دقیقاً برابر با یکدیگر باشد، بیشینه مقدار ضرایب همخوانی بین نمره ها برابر با 1+ خواهد بود. اما به عکس، ضریب همخوانی 1+ دلالت بر این ندارد که دو مجموعه داده های مورد مطالعه دقیقاً برابر با یکدیگر است. داوران مختلف در واقع تنها درباره وضع نسبی افراد، چیزها یا پدیده ها دا...

The Lo Go-Xa Mat is a national park in the southeastern region of Vietnam, which has a particularly high biodiversity and it includes different wetlands which are unique diverse in species composition. It can be categorized into two types: temporarily-seasonally and permanently flooded wetlands. Ta Not grassy marsh is representative of the seasonally flooded wetland. Whilst the diversity and ec...
