Ecology Of The Malay Civet (Viverra Tangalunga) In A Logged And An Unlogged Forest In Sabah, East Malaysia, Christina P. Colon

Publications and Research

Malay civets in a dipterocarp rain forest were studied from December, 1995, through June, 1997, in the Ulu Segama Forest Reserve in Sabah, East Malaysia. To investigate the basic ecology of this species and explore the potential impact of selective logging, data on home range, activity and diet were collected on study animals in an unlogged and a selectively logged forest, and comparisons made.

Density in the unlogged forest was 1/0.46 km² , and 1/1.07 km² in the logged forest. Mean home range size based on a 95% minimum convex polygon was 110 ha. and did not differ …

Analysis Of Intraguild Predation With A Consideration Of Adaptive Foraging, Toshinori Okuyama

School of Biological Sciences: Dissertations, Theses, and Student Research

Identification of interactive units in food webs is particularly important in population and community ecology. Intraguild predation has gained much attention recently with the recognition of its prevalence in the field, although its significance has not been fully studied. Nature contains much more complex interactions than a simple food chain. Yet, much theory still focuses on the trophic levels connected in a single linear chain. In this thesis, I study intraguild predation including the consideration of animal behavior whose importance is also often neglected in population and community ecology.

First, the concepts of intraguild predation and animal behavior are introduced. …

The Ecology And Life History Of The Mexican Tetra, Astyanax Mexicanus, (Teleostei: Characidae) In The Lower Rio Grande Valley, Texas, Mario Estrada

Theses and Dissertations - UTB/UTPA

The Mexican tetra has been found to migrate from shallow waters in the spring and summer months into deeper waters during the winter months when temperatures are too cold for their survival. This fish is omnivorous with insect material being the major source of food. Its food types include green algae, nematoceran larvae, hemipterans, coleopterans, hymenopterans, dipterans, ostracods, fish eggs and amphipods. Furthermore, size classes showed that the Mexican tetras reached their largest size at the River site and smaller sizes at the Bridge and Gate sites and apparently breed year round. They are capable of producing from 300 to …

This Cat's Meow: Individual Variation Among Domestic Cats In Maternal Response To An Unrelated Kitten, Theressa Joanne Silver

Dissertations and Theses

Non-offspring nursing and adoption are puzzling behaviors seen in a number of mammalian species (Riedman, 1982; Packer et al., 1992). Although domestic cats show a proclivity for adopting strange kittens, there is a great deal of individual variation in the behavior. The goal of this project was to determine the feasibility of using behavioral observations and other measures of a mother cat's personality to predict her reaction to a strange kitten. Twelve female domestic cats with litters of kittens were tested. Three behavioral tests were done with each cat: New Person Test (NPT), Familiar Person Test (FPT), and Novel Box …

Cooperative Whooping Crane Tracking Project (August 1998-January 1999)

Nebraska Bird Review

Between 1977 and 1988, 132 juvenile whooping cranes were color-marked on the breeding grounds; of these 37 were accounted for during the winter of 1998-99. Five color-marked cranes were observed during the fall migration. All sightings of color-marked cranes during migration are maintained at the Grand Island office.

One hundred eighty-one cranes began the 1998 spring migration. Forty-nine nests were confirmed on the breeding grounds. Forty-seven chicks were located during June surveys, and the surveys during August determined that at least 24 chicks were surviving. Under optimum conditions about 2,054 birds were expected to arrive at Aransas last fall. The …

The 1998-99 Nebraska Christmas Bird Count Summary, Stephen J. Dinsmore

Nebraska Bird Review

The 1998-99 Christmas Bird Count (CBC) period included eight counts in Nebraska. Counts were scattered statewide, but most effort was in the eastern half of the state. I know of at least one additional count (Branched Oak Lake) that was run this year, but not submitted.

In the following discussion, I have attempted to discuss what I believe are the more important aspects of this year's CBC period. This includes my general impressions about some of the commoner species, mention of rarities, notable misses, and other topics.

The Age Of Birds In Nebraska, Paul A. Johnsgard

Nebraska Bird Review

Let each mile of highway I-80 represent a million years. That way, 1/2 mile represents 500,000 years, 1/10 mile = 100,000 years, 1/100 mile (52 feet) = 10,000 years; 1/1000 mile (5.2 feet) = 1,000 years, and 6 inches = 100 years. A decade (ten years) equals about a half-inch. It is 450 miles from the 60th St. on-ramp to I-80 in Omaha to the westernmost exit at the Wyoming border. These 450 million years encompass most of the time that evidence of life has been found on earth, but the earth itself is more than four billion years old, …

Two Winter Records Of Pacific Loons At Lake Mcconaughy, Stephen J. Dinsmore

Nebraska Bird Review

Pacific Loons are rare migrants in Nebraska, with most of the recent records coming from the western half of the state. Many of the recent records are from Lake McConaughy in Keith County and from Lake Minatare in Scotts Bluff County. Most records are from fall in the short period between 20 October and 20 November. There is a single spring record from April, 5 summer records in the period June to August (all but one from western Nebraska), and a few fall records outside the peak period. The latest fall record from Nebraska is 9 December. In this note, …

Winter Field Report, Dec 1998-Feb 1999, W. Ross Silcock, Joel G. Jorgensen

Nebraska Bird Review

First we want to correct a rather obvious error in the Summer Field Report. We reported 3 pairs of Cordilleran Flycatchers at Neale Woods at the eastern edge of the state, which would be a remarkable range expansion. These birds were actually in Monroe Canyon, Sioux Co, where they were supposed to be. Another error involved 5 Brewer's Sparrows we said were in Sioux Co; these were actually Brewer's Blackbirds.

Several contributors now report to us by email. We urge observers to forward their email addresses; if we have questions on their reports, communication would be easy! Reports and comments …

Chemical Communication Of Estrous Cycle Status And Change In Social Behaviors With Reproductive State In Captive Female Asian Elephants, Elephas Maximus, Barbara Elaine Slade

Dissertations and Theses

Elephants use several well-developed sensory systems for communicating within and between social groups. Female elephants sniff, touch and flehmen to the urine and genitals of herdmembers. In addition, communication through social behaviors is prevalent. Female elephants frequently communicate through affiliate tactile and aggressive behaviors. Furthermore, although female elephants are not known to display behavioral signs of estrus, these females exhibit a tail slapping behavior that may be an implement for dispersing chemical signals to conspecifics or nearby male elephants.

The present study addresses two areas of research. The purpose of part one was first, to determine if female Asian elephants …

Copper, Zinc, Lead And Cadmium Concentrations In The Mediterranean Mussel Mytilus Galloprovincialislamarck,1819 From The Sinop Coast Of The Black Sea, Levent Bat, Ayşe Gündoğdu, Meral Öztürk, Mehmet Öztürk

Turkish Journal of Zoology

Testaceous amoebae in plankton peryphithon and benthos of the Ganlı-Gol lake in the Baku suburbs were investigated with respect to specific composition and number. Twenty-four of 64 species were recognized as a new faunal assemblage for the Caucasus. The largest diversity and number of species df testaceous amoebae occurred in benthos in silty deposits. Representatives of Difflugiidae, Centropyxidae and Arcellidae families appear to be dominant on the basis of the abundance of species.

A Review On The Control Of Eutrophication In Deep And Shallow Lakes, Meryem Bekli̇oğlu

Turkish Journal of Zoology

There has been a much debate about the relative importance of the determination of phytoplankton crops by nutrients (bottom-up control) or by zooplankton grazing (top-down control). Wide acceptance of the importance of nutrient concentrations in water quality deterioration has brought about external nutrient control by which eutrophication is, to some extent, reversible, and which has been proved its effectiveness mostly in deep lakes. In shallow lakes its effectiveness has not been as pronounced, owing to internal nutrient loading. Because the non-linearity of responses of biological systems is much more accentuated in small and shallow lakes. The use of profound effects …

Diurnal Variation Of Water Chemistry Andzooplankton In Little Mere, Cheshire, Uk, In 1993 And 1994, Meryem Bekli̇oğlu, Brian Moss

Turkish Journal of Zoology

In Little Mere, diurnal sampling of the zooplankton at three different habitats in 1993 provided little evidence to support the data of Timms and Moss (10) that cladocerans move out from refugia at night to graze in open water. The floating-leaved water lily, appeared to be more efficient at providing refuge to D. hyalina in the presence of high planktivore fish predation than the submerged plant beds and the open water. This might be due to unfavourable physical and chemical environmental conditions associated with the water lily bed for fish feeding, a possibility supported by the findings of very low …

Responses Of Meteorus Versicolor Wesm. (Hymenoptera, Braconidae) To The Population Density Of Tephrina Arenacearia Den. Et Schiff. (Lepidoptera. Geomatridae), Ilhama Gudrat Gizi Kerimova, Arifa Akhmed Gizi Abdinbekova

Accumulation Of Some Heavy Metals In Tilapia Zillii Organs From Lake Manzalah, Egypt, Mohamed Ali̇ Zyadah

Turkish Journal of Zoology

The accumulation of copper, zinc, cadmium and lead in flesh, gills, liver and gonads of Tilapia zillii were determined. Fish sizes, sexes and metal accumulation by the fish organs were studied. The levels of those heavy metals are occasionally higher in females than in males, this could be attributed to the fact that females have a higher tendency to accumulate heavy metals in fish 8- 11 cm in length were obtained, while medium sizes of fish (11-13 cm) showed more remarkable concentrations than the other sizes through both seasons and sites. The flesh accumulated low concentrations of heavy metals in …

Some Morphological Features Of The Rectal Sac Of The Silkworm (Bombyx Mori: Bombycidae), Beri̇a Falakali Mutaf, Gamze Turgay

Turkish Journal of Zoology

The silkworm moth escapes from the pupal-protection case by utilizing cocoon-digesting enzymes. The rectal sac was examined in relation to the behaviour of the animal. Pupae and pharate adults were obtained from commercial races and were reared in the laboratory. The ball-shaped rectal sac, easily distinguishable within the abdomen of the silkworm, was found to contain two phased creamy fluid. The occurance and the shape of the organ and the usage of its fluid suggest its role in perforation of the cocoon.
