| lead poisoning in woodpeckers in sweden. | lead poisoning was demonstrated in two gray-headed woodpeckers (picus canus) and one white-backed woodpecker (dendrocopus leucotos) in sweden; they had liver lead levels between 9.4 and 26.2 mg(-1) wet weight. at necropsy one gray-headed woodpecker showed signs of emaciation and the other one had severe traumatic injuries, caused by a cat. the white-backed woodpecker died in the transportation box during a translocation program. the source of the lead could not be determined, but it was suspecte ... | 1999 | 10574536 |
| prospects for the use of biological control agents against anoplophora in europe. | this review summarises the literature on the biological control of anoplophora spp. (coleoptera: cerambycidae) and discusses its potential for use in europe. entomopathogenic fungi: beauveria brongniartii petch (hypocreales: cordycipitaceae) has already been developed into a commercial product in japan, and fungal infection results in high mortality rates. parasitic nematodes: steinernema feltiae filipjev (rhabditida: steinernematidae) and steinernema carpocapsae weiser have potential for use as ... | 2015 | 25216358 |
| two new species of haemoproteus kruse, 1890 (haemosporida, haemoproteidae) from european birds, with emphasis on dna barcoding for detection of haemosporidians in wildlife. | two new species of haemoproteus kruse, 1890 (haemosporida, haemoproteidae) are described: haemoproteus (parahaemoproteus) homovelans n. sp. from grey-faced woodpecker, picus canus gmelin, and haemoproteus (parahaemoproteus) concavocentralis n. sp. recorded in hawfinch, coccothraustes coccothraustes (linnaeus), both sampled in bulgaria. the morphology of the gametocytes and their host-cells are described and mitochondrial cytochrome b (cyt b) gene sequences are generated. haemoproteus homovelans ... | 2014 | 24474037 |
| dispersal of remnant endangered trees in a fragmented and disturbed forest by frugivorous birds. | most endangered plant species in a fragmented forest behave as a unique source population, with a high dependence on frugivorous birds for recruitment and persistence. in this study, we combined field data of dispersal behavior of birds and gis information of patch attributes to estimate how frugivorous birds could affect the effective dispersal pattern of chinese yew (taxus chinensis) in a fragmented and disturbed forest. nine bird species were observed to visit t. chinensis trees, with urociss ... | 2017 | 28389923 |
| impact of multiple bird partners on the seed dispersal effectiveness of china's relic trees. | frugivorous birds generally exhibit an unequal contribution to dispersal effectiveness of plant species as a function of their habitat adaptation and body size. in our study, we compared the effectiveness of multiple bird species that contribute to the dispersal of the endangered relic chinese yew, taxus chinensis. seven bird species dispersed t. chinensis seeds, with picus canus, turdus hortulorum, and urocissa erythrorhyncha being the main dispersers. the quantity part of dispersal effectivene ... | 2016 | 26725517 |
