Projected mercury dietary exposure of three bird species nesting on a contaminated floodplain (South River, VA, USA)
Dietary mercury exposure was modeled for Carolina wren (Thryothorus ludovicianus), Eastern song sparrow (Melospiza melodia) and Eastern screech owl (Otus asio) nesting on the contaminated South River floodplain (Virginia, USA). Parameterization of Monte Carlo models required formal expert elicitation to define bird body weight and feeding ecology characteristics because specific information was ...

A study describes the migratory divide towards the pacific ocean and the Arabian sea in red-neck phalarope populations
When winter comes, populations of red-neck phalarope from the Western Palearctic migrate to two different destinations –the Pacific Ocean or the Arabian Sea- following an exceptional migratory divide strategy which has never been described in this geographical area. When winter comes, populations of red-neck phalarope from the Western Palearctic migrate to two different destinations ...

Quantifying the effects of pesticide exposure on annual reproductive success of birds
The Markov chain nest productivity model (MCnest) was developed for quantifying the effects of specific pesticide‐use scenarios on the annual reproductive success of simulated populations of birds. Each nesting attempt is divided into a series of discrete phases (e.g., egg laying, incubation, nestling rearing), and results from avian toxicity tests are used to represent the types of effects ...

Local and interannual variations in mercury and cadmium in eggs of eight seabird species of the Sinaloa coast, México
Mercury (Hg) and cadmium (Cd) concentrations in eggs of eight seabird species inhabiting five coastal ecosystems in Sinaloa, México were determined during two breeding seasons (2012 and 2013): Blue‐footed Booby (BFBO; Sula nebouxii), Brown Booby (BRBO; S. leucogaster), Double‐crested Cormorant (DCCO; Phalacrocorax auritus), Magnificent Frigatebird (MAFR; Fregata magnificens), Brown Pelican ...

Community response to ban on fishing and associated environmental problems: lesson learnt from River Swat, North of Pakistan
This study was conducted during 2006–2010 on River Swat, North of Pakistan. River Swat is the largest tributary of the Kabul River, which ultimately joins the Indus River. Fishing is a regular activity on the entire River Swat and is a major source of recreation and livelihood. This activity caused a decline in fish populations and ultimately fishing has been banned since 1982. This study ...

Breeding effects on grain filling, biomass partitioning, and remobilization in mediterranean durum wheat
This work assesses the changes resulting from durum wheat (Triticum turgidum L. var. durum) breeding in Italy and Spain during the 20th century on grain filling, biomass production, and allocation at anthesis, and the remobilization of preanthesis photosynthates to the grain of main stems. Field experiments, involving 12 Italian and 12 Spanish cultivars released at different periods, were ...

Advancements in chemistry are providing growers with flexibility when managing slug pressures in potato crops.
Flexibility in slug control The mild and wet weather and lack of ground frosts seen this winter, means that being vigilant to slug activity will be key as we move into the potato planting season. Andrew Sprunt, Agrii’s Northern region potato technical agronomist, explains what growers can expect from the season ahead, and how to manage the potential impact at farm level, particularly in ...

The Secret Lives of Carnivorous Marsupials: biology with bite
Dr Marissa Parrott reveals the trials and tribulations of studying one of Australia’s carnivorous marsupials – the somewhat fierce, and certainly fascinating, Agile Antechinus. Predators come in all shapes and sizes, and Australia’s carnivorous marsupials are no exception. From miniscule marsupials weighing just a few grams, to Tasmanian Devils, which reach dog-sized ...
