Shutler D. Sexual selection: when to expect trade-offs. Biol Lett. 2011;7:101-4 pubmed publisher
..Moreover, there are currently too few empirical distributions to make generalizations about the likelihood of interspecific trade-offs in sexually selected traits. ..

..and for breeding common loons (where mean fish muscle Hg concentrations exceeded 0.8Â Î¼g/g dry wt., and loon chick blood Hg exceeded 1.4Â Î¼g/g dry wt.) had pHÂ <Â 6.7 and were located in eastern Canada. ..
Muchhala N, Caiza A, Vizuete J, Thomson J. A generalized pollination system in the tropics: bats, birds and Aphelandra acanthus. Ann Bot. 2009;103:1481-7 pubmed publisher
..It is suggested that the negative effects of interspecific pollen transfer may decrease bat 'quality' for A. acanthus, and thus select for generalization on multiple pollinators instead of specialization on bats. ..
Peck L, Gilchrist H, Mallory C, Braune B, Mallory M. Persistent organic pollutant and mercury concentrations in eggs of ground-nesting marine birds in the Canadian high Arctic. Sci Total Environ. 2016;556:80-8 pubmed publisher
..We also noted that total hexachlorocyclohexanes were higher than reported elsewhere in the circumpolar Arctic in three species. ..
Simpson V. Leucocytozoon-like infection in parakeets, budgerigars and a common buzzard. Vet Rec. 1991;129:30-2 pubmed
..The infection appears not to have been identified before in budgerigars in Great Britain, and in its chronic form resulted in vomiting and wasting. The possible identity of the parasite and the epidemiological factors are considered...
Sanford S, Rehmtulla A, Josephson G. Tuberculosis in farmed rheas (Rhea americana). Avian Dis. 1994;38:193-6 pubmed
..Amyloidosis of the liver and spleen occurred in one rhea. Mycobacterium avium complex was isolated at a reference laboratory from hepatic granulomas submitted from one rhea...

..3, and 4 versus 2 pairs of sessile papillae. The new species differs from E. columbi in having 1 versus 2 lateral alae, in the length of the spicules, in having a different spicule ratio, and in the numbers of sessile papillae...
Bidleman T, Helm P, Braune B, Gabrielsen G. Polychlorinated naphthalenes in polar environments--a review. Sci Total Environ. 2010;408:2919-35 pubmed publisher
..PCNs accounted for <1% of total TEQ in ringed seal, Weddell seal, seabirds and polar bear, but up to 6-15% in beluga and pilot whale. TEQ due to PCNs were generally low in harbour seal, but up to 9% of total TEQ in some animals. ..
Taylor P, Brzustowski J, Matkovich C, Peckford M, Wilson D. radR: an open-source platform for acquiring and analysing data on biological targets observed by surveillance radar. BMC Ecol. 2010;10:22 pubmed publisher
..We also provide an overview of the basic considerations of setting up and running a biological radar study. Program radR provides a convenient, open source platform for the acquisition and analysis of radar data of biological targets. ..
