The effect of cross-seasonal interactions on reproduction and fitness in migratory species is of increasing interest to ecologists, particularly because of the conservation implications of habitat change. Variation in contaminant levels that can affe

Herring gulls (Larus argentatus) bioaccumulate mercury (Hg) but it is unknown whether they are exposed at levels of neurological concern. Here we studied brain tissues from gulls at five Great Lakes colonies and one non-Great Lakes colony during spri

The effects of lead (Pb2+) and various pesticides on δ-aminolevulinic acid dehydratase (ALA-d) in avian blood, liver and kidney were studied. In blood, virtually all of the ALA-d activity was localized in the cellular fraction. Complete inhibition o

Leg and foot bones of adult and juvenile red grouse (Lagopus lagopus scoticus) were collected from hunter-shot birds on two Scottish estates (Glendye and Invermark) and one Yorkshire estate in September, 2003. The lead content of bones was measured b

Background, aim, and scope Hexanitrohexaazaisowurtzitane (CL-20) is a relatively new energetic compound sharing some degree of structural similarity with hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX), a known neurotoxic compound. Previously, we demon

Subsurface soils near Clyde Forks, Ontario, Canada, can have naturally high concentrations of mercury (Hg) from local geological sources. To investigate Hg in local aquatic food webs, Hg was measured in fish dorsal muscle (mainly yellow perch [YP] an

Big Dam West, located in Kejimkujik Park, Nova Scotia, Canada, is a remote lake with elevated Hg concentrations in fish due in part to low pH and high dissolved organic carbon (DOC) concentrations. These features reflect the poor buffering capacity o

Mercury (Hg) impairs glutamate homeostasis but little is known about its effects on the N-methyl-d-aspartic acid (NMDA) receptor. Here, we investigated NMDA receptor levels, as determined by [(3)H]-MK801 binding, in both wild and captive mink (Mustel
