Fluctuation Of A Marsh Habitat And The Reproductive Strategy Of The Yellow-Headed Blackbird, Roger J. Lederer Mar 1978

Fluctuation Of A Marsh Habitat And The Reproductive Strategy Of The Yellow-Headed Blackbird, Roger J. Lederer

Great Basin Naturalist

The Yellow-headed Blackbird (Xanthocephalus xanthocephalus) nests in marshes and is dependent on emergent vegetation for nest sites. Fluctuating water levels from year to year cause an increase or decrease in the amount of emergent vegetation and affect the time required for the vegetation to become suitable for nesting. Nests built in marshes are very susceptible to wind, rainfall, vegetation growth, and predation. Many nests are abandoned before being used and the mortality of eggs and young is high. The reproductive strategy of the Yellow-headed Blackbird has been selected for flexibility and opportunism to compensate for the unpredictability of …


Allelopathic Effects Of Bur Buttercup Tissue On Germination And Growth Of Various Grasses And Forbs In Vitro And In Soil, Bruce A. Buchanan, K. T. Harper, Neil C. Frischknecht Mar 1978

Allelopathic Effects Of Bur Buttercup Tissue On Germination And Growth Of Various Grasses And Forbs In Vitro And In Soil, Bruce A. Buchanan, K. T. Harper, Neil C. Frischknecht

Great Basin Naturalist

The allelopathic effects of bur buttercup (Ranunculus testiculatus) tissue on selected grasses and forbs varied according to the substratum for germination and growth. The in vitro effects of an aqueous extract of buttercup tissue on germination and root development of five grasses were strongly inhibitory in all cases. However, in soil the effects of buttercup tissue on germination and growth of seven grasses and two dicotyledonous herbs were small to nonsignificant. Deleterious effects were less severe in fine- as opposed to coarse-textured soils. Under field conditions, the ability of seedlings of the grasses to compete with buttercup varied …


New Species Of Nearctic Neoperla (Plecoptera: Perlidae), With Notes On The Genus, Bill P. Stark, Richard W. Baumann Mar 1978

New Species Of Nearctic Neoperla (Plecoptera: Perlidae), With Notes On The Genus, Bill P. Stark, Richard W. Baumann

Great Basin Naturalist

The Nearctic Neoperla are reviewed. Eight species, placed in two nominal groups, are recognized. Neoperla carlsoni, new species, N. catharae, new species, N. choctaw, new species, N. freytagi, new species, N. gaufini, new species, and N. stewarti, new species, are described for male, female, and egg. Male holotypes and female allotypes are designated for each species. Neoperla mainensis Banks and N. clymene (Newman) are redescribed and mainensis is raised to species. Descriptions are supported by original drawings and stereoscan photomicrographs. Relationships of Nearctic species groups to the world fauna are discussed.

Basidiomycetes That Decay Junipers In Arizona. Ii, R. L. Gilbertson, J. P. Lindsey

Great Basin Naturalist

Five additional species of wood rotting basidiomycetes on Arizona junipers are described and illustrated. All cause a white rot of dead, fallen trees. Leptosporomyces juniperinus is proposed as a new species. Vararia fibra is reported from the United States for the first time.


Morphometry Of Sculpins (Cottus) In The Clearwater Drainage, Idaho, O. Eugene Maughan Mar 1978

Morphometry Of Sculpins (Cottus) In The Clearwater Drainage, Idaho, O. Eugene Maughan

Great Basin Naturalist

The morphometry of four Idaho species of Cottidae were compared. Pectoral ray counts allowed separation of Cottus beldingi and C. confusus from C. bairdi and C. rhotheus but not from each other. Preopercular armature also allowed identification of the same two groups of two species. Palatine tooth development generally allowed separation of each species as did body prickle development. Body ratios involving caudal peduncle depth allowed separation of C. rhotheus and C. bairdi. Development of lateral lines allowed differentiation of C. rhotheus from the other three species. A key was developed based on the combination of characters studied.


New Synonymy, New Species, And Taxonomic Notes Of North American Pityophthorus (Coleoptera: Scolytidae), Part Iii, Donald E. Bright Mar 1978

New Synonymy, New Species, And Taxonomic Notes Of North American Pityophthorus (Coleoptera: Scolytidae), Part Iii, Donald E. Bright

Great Basin Naturalist

New synonymies and new data affecting North American Pityophthorus are proposed as follows: chalcoensis Hopkins ( = herrerai Hopkins) and nigricans Blandford ( = chiapensis Bright). Neotypes are designated for the following species described by Eichhoff: concentralis, cribripennis, infans, puchellus, and tuberculatus. New species are: carinatus (Canada), cavatus (Manitoba, Saskatchewan), euterpes (Mexico), hesperius (British Columbia), impexus (Mexico), intentus (Arizona), laticeps (Mexico), malleatus (Arizona), mesembria (Guatemala), montezumae (Mexico), scalptus (British Columbia, Colorado), trepidus (California), and vespertinus (Mexico).
