Abundance, Growth, And Predation By Non-Native Brown Trout In The Trinity River, Ca, Justin S. Alvarez

Cal Poly Humboldt theses and projects

Brown Trout were introduced to the Trinity River in Northern California in the 1890’s. Since 1932, Brown Trout have sustained their population without additional stocking. Over the last 15 years, fisheries managers have been concerned that predation by piscivorous Brown Trout may impede efforts to restore native salmonids, in particular endangered Coho Salmon. I investigated predation by Brown Trout on native fish in the 64 km of the main stem Trinity River below Lewiston Dam. Using a bioenergetics approach parameterized with field measurements of Brown Trout abundance and growth, I estimated the amount of energy needed to sustain the 2015 …

The Bee Fauna Of The Horse Mountain And Grouse Mountain Region, Humboldt County, California, Carrie Lopez

Cal Poly Humboldt theses and projects

Recent concerns about the ecological well-being of bee communities in California and elsewhere have increased the need for monitoring programs and studies that evaluate the impact of habitat loss and alteration on bee diversity and abundance. Such studies depend critically on the expertise of people trained in taxonomy, but their numbers have declined in recent years. My primary goal was to gain a comprehensive first-hand experience with bee identification by documenting the fauna of a previously unstudied area in the mountains of northwestern California and by writing an identification key, intended for dedicated non-specialists, to the area’s 35 species of …

Mobbing Behavior In Wild Steller's Jay (Cyanocitta Stelleri), Kelly Anne Commons

Cal Poly Humboldt theses and projects

Mobbing is a widespread anti-predator behavior with multifaceted functions. Mobbing behavior has been found to differ with respect to many individual, group, and encounter level factors. To better understand the factors that influence mobbing behavior in wild Steller’s jays (Cyanocitta stelleri), I induced mobbing behavior using 3 predator mounts: a great horned owl (Bubo virginianus), common raven (Corvus corax), and sharp-shinned hawk (Accipiter cooperii). I observed 90 responses to mock predators by 33 color-marked individuals and found that jays varied in their attendance at mobbing trials, their alarm calling behavior, and in …

Similarly, samples from eight localities (four natural populations: LVG/LKG, LTA, LBA, and four farmed: SAN, SAG, KIB, UoE) were genotyped using …

Multiscale Habitat Suitability Modeling For Canary Rockfish (Sebastes Pinniger) Along The Northern California Coast, Portia N. Saucedo

Cal Poly Humboldt theses and projects

Detailed spatially-explicit data of the potential habitat of commercially important rockfish species are a critical component for the purposes of marine conservation, evaluation, and planning. Predictive habitat modeling techniques are widely used to identify suitable habitat in un-surveyed regions. This study elucidates the predicted distribution of canary rockfish (Sebastes pinniger) along the largely un-surveyed northern California coast using data from visual underwater surveys and predictive terrain complexity covariates. I used Maximum Entropy (MaxEnt) modelling software to identify regions of suitable habitat for S. pinniger greater than nine cm in total length at two spatial scales. The results of …

Seasonal And Ontogenetic Diet Shift Of Two Sympatric Cyprinid Fish Species From The Temperate Karamenderes River, Çanakkale, Turkey, Şükran Yalçin Özdi̇lek

Turkish Journal of Zoology

Diet composition and feeding relationships of two cyprinid species, Squalius cii and Barbus oligolepis, from the Karamenderes River, northwestern Turkey, were assessed over a 1-year period. Both species were omnivorous and fed mostly on benthic plant materials (particularly algae) and insects. The diet of B. oligolepis primarily comprised Bacillariophyceae, Diptera larvae, and other insects, while that of S. cii comprised filamentous algae (Cyanobacteria and Chlorophyceae), insect larvae, and adults. Ontogenetic shifts in diet were identified in both species. The ratio of Chlorophyceae in the diet of B. oligolepis showed a gradual increase with increase in its body size; moreover, the …

Review Of The Brachypterous Species Of Alloxysta Förster, 1869(Hymenoptera: Cynipoidea: Figitidae: Charipinae) With A Description Of Two New Species, Mar Ferrer Suay, Jesus Selfa, Maria Victoria Seco-Fernandez, Jili Pujade-Villar

Turkish Journal of Zoology

The aim of this study is to review the brachypterous species within the genus Alloxysta Förster, 1869. The known brachypterous species of Alloxysta have been compared with fully winged species in order to establish hypotheses regarding dimorphism for wing length and shape. This analysis is based only on the morphological features shared between species; breeding and genetic analyses will be necessary to test and refine these hypotheses. Two new brachypterous species are described here: Alloxysta curta Ferrer-Suay sp. nov. and Alloxysta pseudoconsobrina Ferrer-Suay sp. nov. Six species are revised. In total, there are now 8 brachypterous species known in this …

Heterochromatin Distribution And Localization Of Nors In The 2n = 48cytotypes Of Nannospalax Xanthodon And N. Ehrenbergi, Ati̇lla Arslan, Jan Zima

Turkish Journal of Zoology

We compared the C-banding pattern and the NOR distribution in 3 populations of N. xanthodon and N. ehrenbergi with 48 chromosomes from Turkey, with the aim to reveal variations between and within species. We have found distinct variation in the C-banding and the NOR distribution pattern among the 3 populations compared; each of them possessed its own specific chromosomal features. However, it is not possible to distinguish between intra- and interspecific variation, and the observed patterns cannot be utilized for unequivocal species recognition.
