| persistent organochlorine levels in six prey species of the gyrfalcon falco rusticolus in iceland. | our previous investigations have revealed very high levels of organochlorines (ocs) in the icelandic gyrfalcon falco rusticolus, a resident top predator. we now examine six potential prey species of birds, both resident and migratory, in order to elucidate the most likely route of the ocs to the gyrfalcon. the ptarmigan lagopus mutus, the most important prey of the gyrfalcon, contained very low levels of ocs. bioaccumulation of polychlorinated biphenyls (pcbs) and ddts in mallards anas platyrhyn ... | 2001 | 11234542 |
| contrast in adaptive mass gains: eurasian golden plovers store fat before midwinter and protein before prebreeding flight. | before predictable periods of high nutritional demand and little or no intake, vertebrates store fuel mainly composed of energy-dense lipids or energy-poor but protein-rich muscle tissue. documenting contrasts in fuel composition and storage patterns within species, or even within individuals, would greatly help to elucidate the functional significance of the variety of storage strategies demonstrated in birds. we show here that the 40-50 g mass gain of 200 g in eurasian golden plovers (pluviali ... | 2002 | 12061951 |
| vision and touch in relation to foraging and predator detection: insightful contrasts between a plover and a sandpiper. | visual fields were determined in two species of shorebirds (charadriiformes) whose foraging is guided primarily by different sources of information: red knots (calidris canutus, tactile foragers) and european golden plovers (pluvialis apricaria, visual foragers). the visual fields of both species showed features that are found in a wide range of birds whose foraging involves precision pecking or lunging at food items. surprisingly, red knots did not show comprehensive panoramic vision as found i ... | 2009 | 18842546 |
| estimating organ size in small migrating shorebirds with ultrasonography: an intercalibration exercise. | organs, even of fully grown adult birds, mammals, and reptiles, may show substantial size changes in relation to specific performances. these changes are difficult to study, because measurements usually can only be obtained following the death of the animal. we explored the use of ultrasonographic imaging, a relatively simple noninvasive technique, to measure size of pectoral muscles and stomach in two small shorebird species (red knots calidris canutus and golden plovers pluvialis apricaria). a ... | 2016 | 9882600 |
| a review of the subfamily picobiinae johnston and kethley, 1973 (acariformes: prostigmata: syringophilidae). | the fauna of quill mites of the subfamily picobiinae johnston and kethley, 1973 (acariformes: cheyletoidea: syringophilidae) is comprehensively revised. all of 78 known species, which are grouped into 11 genera, are examined and diagnosed or redescribed. data on picobiine hosts and distribution are summarized, including new host and locality records. the following new species are described: charadriineopicobia apricaria sp. nov. ex pluvialis apricaria (linnaeus) (charadriiformes: charadriidae) f ... | 2016 | 27395108 |
| warmer springs advance the breeding phenology of golden plovers pluvialis apricaria and their prey (tipulidae). | most studies of climate-driven changes in avian breeding phenology have focused on temperate passerines, yet the consequences of such environmental change may be more deleterious for other avian taxa, such as arctic and sub-arctic waders (charadrii). we therefore examine large-scale climatic correlates of the breeding phenology of one such species (golden plover pluvialis apricaria), and the timing of emergence of their adult tipulid prey, to assess the potential for climate change to disrupt br ... | 2005 | 15685442 |

| the influence of different aspects of grouse moorland management on nontarget bird assemblages. | conflict between stakeholders with opposing interests can hamper biodiversity conservation. when conflicts become entrenched, evidence from applied ecology can reveal new ways forward for their management. in particular, where disagreement exists over the efficacy or ethics of management actions, research clarifying the uncertain impacts of management on wildlife can move debates forwards to conciliation.here, we explore a case-study of entrenched conflict where uncertainty exists over the impac ... | 2019 | 31641457 |
