The Presence Of Micropterus Salmoides (Largemouth Bass) Influences The Populations Of Rana Draytonii (California Red-Legged Frog) And Pseudacris Regilla (Pacific Treefrog) In Two Ponds In Santa Barbara County, California, Kenneth Lee Gilliland
Master's Theses
Alien fish have been implicated in the decline of Rana draytonii (California red-legged frog) and Pseudacris regilla (Pacific treefrog) populations. Micropterus salmoides (largemouth bass) is a common sport fish that has been introduced into the sympatric range of these two anuran species; however, no studies have investigated the individual influence that this alien fish has on these two species. I conducted M. salmoides control or eradication experiments during a four year study in two ponds within the Transverse Mountain Range of Santa Barbara County, California. Changes in the densities of all life stages of R. draytonii and P. regilla were …
The Identification Of Rana Ocellata Linnaeus, 1758. Nomenclatural Impact On The Species Currently Known As Leptodactylus Ocellatus (Leptodactylidae) And Osteopilus Brunneus (Gosse, 1851) (Hylidae), Esteban O. Lavilla, José A. Langone, Ulisses Caramaschi, W. Ronald Heyer, Rafael O. De Sá
The Identification Of Rana Ocellata Linnaeus, 1758. Nomenclatural Impact On The Species Currently Known As Leptodactylus Ocellatus (Leptodactylidae) And Osteopilus Brunneus (Gosse, 1851) (Hylidae), Esteban O. Lavilla, José A. Langone, Ulisses Caramaschi, W. Ronald Heyer, Rafael O. De Sá
Biology Faculty Publications
The usage of the name Rana ocellata Linnaeus, 1758, is plagued by misidentifications and misinterpretations. After an exhaustive bibliographic review, we conclude that the Linnaeus 1758 name refers to Osteopilus brunneus (Gosse, 1851) from Jamaica, while the taxon currently known as Leptodactylus ocellatus corresponds to Rana latrans Steffen, 1815. Herein, we designate and provide descriptions of the neotypes of Leptodactylus latrans (Steffen, 1815), revalidated, new combination, and Osteopilus ocellatus (Linnaeus, 1758), new combination, as a senior synonym of Osteopilus brunneus (Gosse, 1851).

Preliminary Phylogeny Of The Thrips Parasitoids Of Turkey Based On Some Morphological Scales And 28s D2 Rdna, With Description Of A New Species, Oguzhan Doğanlar, Mi̇kdat Doğanlar, Anne Frary
Turkish Journal of Zoology
Species of the Ceranisus thrips-attacking genus are difficult to distinguish morphologically. The phylogenetic relationships within the Ceranisus species were explored using nucleotide sequences of the 28S D2 expansion region of the rDNA gene. Bayesian, maximum likelihood, and parsimony inference methods were employed to construct the phylogenetic relationships. Principal component analysis on the Turkish species of Ceranisus, namely antalyacus, menes, bozovaensis, hirsutus, planitianus (a new record for Turkey), pacuvius, and a new species, provided supporting evidence. All known data concerning hosts and geographical distribution are presented. A new species, C. onuri O. Doganlar, sp.n., was described from Turkey.

The Mammals Of The Farasan Archipelago, Saudi Arabia, Marco Masseti
The Mammals Of The Farasan Archipelago, Saudi Arabia, Marco Masseti
Turkish Journal of Zoology
The Farasan archipelago is located in the southern Red Sea, off the south-western coast of Saudi Arabia. Around the beginning of the 1990s, these islands were designated as a marine and terrestrial reserve, mainly for the protection of the Farasan gazelle, which is the only wild ungulate present on the archipelago. As far as is presently known, other mammals reported from the islands are 2 or 3 species of bat, the Eastern spiny mouse, possibly 1 rat, and the white-tailed mongoose. To date there is no evidence for the occurrence of house mice. Furthermore, the occurrence of the Arabian sacred …

Beetles preferred the colour in which they were reared, except for red, which was avoided even by the beetles reared in a red-coloured environment for 3 generations under duress. These beetles moved towards clear tungsten light in a choice chamber. It …
The Effect Of Caloric Restriction On The Population Density Of Freshwater Rotifers (Brachionus Calyciflorus), Ni̇lgün Özdemi̇r, Abdulkadi̇r Çi̇ltaş
The Effect Of Caloric Restriction On The Population Density Of Freshwater Rotifers (Brachionus Calyciflorus), Ni̇lgün Özdemi̇r, Abdulkadi̇r Çi̇ltaş
Turkish Journal of Zoology
The effects of caloric restriction (CR) on the population density of freshwater rotifers (Brachionus calyciflorus) were investigated in the present study. During experiments with different CRs, groups of rotifers were fed with Chlorella sp. at the same concentrations of 1.5 × 10^6 cells/mL at 12, 24, 36, 48, 60, and 72 h intervals for 20 days. Significant changes were observed both in the population density and the peak days in groups subjected to different CRs (P < 0.01). The highest peak in population density was obtained on the fifth day for rotifers fed in 12 h intervals (269 ± 40.12 individuals/mL, mean ± SD). The rate of population increase (r) varied from 0.608 ± 0.073 to 0.288 ± 0.053, depending on the feeding intervals. The results show that CR affected the population density of B. calyciflorus.

Interspecific Variation In Palatability Suggests Cospecialization Of Antipredator Defenses In Sea Hares, Kimberly K. Takagi, Nadia N. Ono, William G. Wright
Interspecific Variation In Palatability Suggests Cospecialization Of Antipredator Defenses In Sea Hares, Kimberly K. Takagi, Nadia N. Ono, William G. Wright
Biology, Chemistry, and Environmental Sciences Faculty Articles and Research
Prey species often deploy different kinds of antipredator defenses, which can interact with each other in ways that are not yet completely understood. Much research into these interactions has utilized gastropod mollusks, usually focusing (in part) on the protective utility of the gastropod shell. This makes the evolutionary reduction of the shell in the opisthobranch gastropods (marine slugs) particularly interesting. This loss of protective function of the shell is associated with the evolution of alternative defenses. Particularly well studied are chemical defenses, especially those using secondary metabolites derived from food resources. As a first step toward understanding interspecific variation in …

Although a number of fish species have been studied in their freshwater life stages, further research on the behavior and habitat requirements of ocean-going fish is required. While fishes have historically been regarded as more “primitive” than other vertebrate groups, Rodriguez et al concluded that several memory and learning systems of bony fishes are noticeably similar to those of reptiles, birds, and mammals. When animals as small and under appreciated as fish display complex mating systems, parental care, and demonstrate the ability to traverse significant distances using olfactory and celestial cues, it is clear that previously established definitions of intelligence …

Understanding the geographic and environmental characteristics of islands that affect aspects of biodiversity is a major theme in ecology (Begon et al. 2006; Krebs 2001) and biogeography (Cox and Moore 2000; Drakare et al. 2006; Lomolino et al. 2006). Such understanding has become particularly relevant over the past century because human activities on continents have fragmented natural landscapes, often creating islands of isolated habitat dispersed within a sea of land uses that include agriculture, forestry, and various degrees of urban and suburban development.
