In May 1974 four male spotted bats were netted near St. George, Utah. Contrary to published speculation on Euderma, indications are that the spotted bat in southwest Utah (1) is not a late flyer, (2) does not feed solely on moths, (3) may drop to the ground on occasion to forage, (4) is not a rapid flyer, and (5) appears to utilize crevices as roosting sites. 相似文献

Before 1990 the spotted bat ( Euderma maculatum ) was known in Wyoming from only 2 records. Between June 1994 and May 1997 we documented habitat use and observations incidental to conducting a bat inventory of caves and abandoned mines. By monitoring audible echolocation calls, we observed bats at mist-netting sites. Spotted bats were heard or captured on 13 nights at 10 locations, all of which were near canyons or high cliff faces. No foraging habitat preferences were noted. E. maculatum occurrence appears to be related to roost structure, roost availability, and proximity to a permanent water source. 相似文献

The spotted bat ( Euderma maculatum ) has been virtually unknown in Oregon despite the existence of potential habitat in many areas of the state. In 2002 and 2003 we searched for spotted bats along the John Day, Deschutes, and Crooked Rivers and at a remote dry canyon southeast of the city of Bend in central Oregon. The species was documented through the use of mist-nets, a bat detector, and recognition of audible spotted bat calls. Spotted bats were found at 11 locations in 6 Oregon counties. Nightly activity patterns of spotted bats were unpredictable. Spotted bats were found in 78% of search areas but on only 48% of survey nights. We observed spotted bats foraging above fields and low upland slopes adjacent to rivers and creeks and along the rims of cliffs. Estimated flying heights of spotted bats ranged from 3 m to 50 m aboveground. The species was difficult to capture and was captured only after considerable experimentation with methods and materials. Three spotted bats were captured toward the end of the project in 2003 and accounted for only 0.5% of all bats captured during the study. Although we attached radio transmitters to 2 spotted bats, we found no roost locations. We believe additional spotted bat surveys in Oregon are warranted, especially in higher-elevation habitats, but recommend that to increase their effectiveness, surveys accommodate the unique foraging behavior of the species. 相似文献

This study investigated local distribution and foraging behavior of the spotted bat ( Euderma maculatum ) in Dinosaur National Monument, Colorado-Utah, by monitoring audible echolocation calls. The occurrence of this species was verified in a variety of habitat types in canyon bottoms and other relatively low elevation sites, indicating that the animals were widely distributed and locally common in the area. Foraging spotted bats concentrated flight activity in the open-air space above meadows occasionally exploited near-canopy habitat (within 8 m of foliage). Bats began to forage shortly after dark, and activity levels were relatively constant throughout the night. Foraging spotted bats attacked airborne prey every 2.15 min on average. Consistent with published observations, spotted bats maintained exclusive foraging areas. Distinct vocalizations indicating agonistic encounters occurred when a bat encroached on the foraging area of a conspecific. 相似文献

The spotted bat ( Euderma maculatum ) is an elusive and rarely captured species in western North America. In the United States, it is known from 12 western states. In New Mexico, few individuals have been reported in recent years, and multiple individuals are known from 9 of 12 capture sites. This study reports on additional captures of E. maculatum from Mt. Taylor (Cibola County) for 2 consecutive summers and includes evidence of a reproducing population in the area. On 30 June/1 July 2006, I captured 4 individuals of E. maculatum , including a lactating female, and on 5 June 2007, I captured a nonreproductive female. The flight of this species was directional and deliberate; I captured 5 of 6 spotted bats that came low over the earthen pond. This study demonstrates how human-made sources of water in an arid region provide opportunities for many species of bats to drink. 相似文献

In June 1974 a scrotal male Mexican big - eared bat ( Plecotus phyllotis ) was netted near Hurricane, Utah. This account represents the third report of the species from Utah and extends the range approximately 330 km west of previous accounts. Adjacent state records are located approximately 64 km to the southeast in Arizona and 80 km southwest in Nevada. 相似文献

Movements of Columbia spotted frogs ( Rana luteiventris ) were determined after breeding to provide managers with information on habitat requirements. We radio-tagged 47 adults and observed movements occurring with 22 frogs. Eleven frogs remained in breeding ponds, and 11 moved to other ponds or river stretches during spring and summer 1998. Distances frogs traveled to other water bodies ranged from 15 to 560 m. Movements appeared to be influenced by availability of habitat and aquatic conditions. Eleven of 16 frogs located within 100 m of other permanent water sources moved, while no frogs at an isolated breeding pond moved. Frogs moved to river stretches in July where water temperatures averaged 5.6 ° C cooler than ponds. Knowledge of Columbia spotted frog movements and habitat use in summer enables land managers to make decisions on activities that affect aquatic sites, vegetation, and stream structures that may influence frog populations. 相似文献

The diamondback moth ( Plutella xylostella [L.]), is one of the most economically important pests of cruciferous plants throughout the world, causing economically significant damage in broccoli, cabbage, canola, collards, and mustard. In Canada, P. xylostella is an important economic pest of canola ( Brassica napus L. and Brassica rapa L.). In North America, the diamondback moth has been collected as far north as Edmonton, Alberta, Canada. Despite its wide distribution and presence at economically damaging levels in Canada, there have been no published reports of P. xylostella from Alaska. This note documents the 1st collection of this pest species in interior Alaska. With continued moderation of the climate due to global climate change, this species has the potential to become an increasingly important agricultural pest in the state. 相似文献

Several western ranid frogs possess a unique strategy of breeding communally over a short temporal window and reusing oviposition sites between years. However, little is published on the characteristics of oviposition sites selected by these explosive breeders. The Columbia spotted frog ( Rana luteiventris ) is native to northwestern North America and is of conservation concern in the southern portions of its range. As part of a study examining relationships between livestock grazing and R. luteiventris habitat, we assessed characteristics of the species' oviposition sites in 25 fishless ponds in northeastern Oregon. Oviposition sites were generally in shallow water (<25 cm) close to shore and tended to be in the northeastern portion of ponds. Oviposition sites were found more frequently over heavily vegetated substrates and in areas of less substrate slope and shade than random points in littoral zones. We did not quantify temperature differences within ponds, but the patterns we documented are consistent with preferential use of warmer microhabitats for oviposition. 相似文献

Members of the algal class Phaeophyceae (brown algae) are almost entirely marine species. A few genera have been described from freshwater habitats, but their distribution and ecological requirements, especially in North America, are very poorly known. The 1st specimens of a freshwater species of brown algae from Oregon, Heribaudiella fluviatilis , were discovered in 3 localities of the McKenzie River, near McKenzie Bridge and Belknap Springs (44°22′N, 122°00′-15′W). This is the 4th extant population of this species known from the United States. The alga forms distinctive, macroscopic, dark brown patches on rocks in rapidly flowing water. In the McKenzie River it co-occurs, apparently year-round, with several other macrophytic algal species, including Prasiola Mexicana , Zygnema sp. (sterile), Nostoc parmelioides , N. vemlcossum , and Phormidium cf. autumnale . In cooler months the macroalgal species Ulothrix zonata and Hydrurus foetidus are also present with Heribaudiella . Photographs and ecological information are provided. We report a 380-km range extension south for the species, and thus far the most southerly population known from North America. This new record suggests that the alga may be more widespread than previously recognized and that other localities may be discovered with further study. 相似文献

An established population of a neotropical cichlid fish, Cichlasoma managuense , was found in a spring pool in the Virgin River basin, Utah. Presence of this predatory species poses an additional threat to the native fish fauna of the Virgin River, which already has suffered multiple impacts of water development and introduced fishes. 相似文献

Terrestrial isopods of the genus Agnara Budde-Lund, 1908 have been recorded from Iran for the first time. Two new species, Agnara tarahomii n. sp. and Agnara haselii n. sp., are described and their diagnostic characters are figured. Agnara tarahomii is characterized by the shape of the male pleopod exopodite I with sinuous distal margin. Agnara haselii is distinguished by a setose area on the ventral margin of the male pereopod VII ischium and the sinuous distal margin of pleopod exopodite I. 相似文献

The family Longosomatidae Hartman, 1944 (Annelida: Polychaeta) is newly reported for Icelandic waters. The diversity, taxonomy and ecology of this poorly-known monogeneric family are reviewed based on material collected during the BIOICE project. Two species of the genus Heterospio are recorded and redescribed: Heterospio longissima Ehlers, 1874 sensu Hartman (1965) and Heterospio reducta Laubier, Picard and Ramos, 1972–73. Several body structures of high taxonomic relevance in the genus are reviewed and discussed. 相似文献
