Bacteroidales diversity in ring-billed gulls (Laurus delawarensis) residing at Lake Michigan beaches.
This study investigated the occurrence and diversity of Bacteroidales fecal bacteria in gulls residing in the Great Lakes region. Members of this bacterial order have been widely employed as human and bovine host-specific markers of fecal pollution; however, few studies have focused on gulls, which can be a major source of fecal indicator bacteria and pathogens at beaches. We found a low but co...
متن کاملFredensborg et al.—Gut helminths from red-billed gulls
Eight species of gastrointestinal helminths were obtained from the red-billed gull (Larus novaehollandiae scopulinus Forster, 1844) from Otago Peninsula, of which six were new host records. One of these, Maritrema novaezelandensis (Trematoda), was a species new to science which is being described elsewhere; the other five were Curtuteria australis (Trematoda), Echinoparyphium recurvatum (Tremat...
متن کاملProbable epizootic chlamydiosis in wild California (Larus californicus) and ring-billed (Larus delawarensis) gulls in North Dakota.
During the summer of 1986, more than 400 California gulls (Larus californicus) and ring-billed gulls (Larvus delawarensis), primarily fledglings, died on an island in Lake Sakakawea near New Town, North Dakota (USA). Mortality was attributed largely to chlamydiosis. Necropsy findings in nine carcasses included splenomegaly (n = 9), hepatomegaly (n = 4), and pericarditis (n = 1). Livers from thr...
متن کاملField Metabolic Rate Is Dependent on Time-Activity Budget in Ring-Billed Gulls (Larus delawarensis) Breeding in an Anthropogenic Environment
Environmental and behavioral factors have long been assumed to affect variation in avian field metabolic rate (FMR). However, due to the difficulties in measuring continuous behavior of birds over prolonged periods of time, complete time-activity budgets have rarely been examined in relation to FMR. Our objective was to determine the effect of activity (measured by detailed time-activity budget...
