Isolation and sequence of cDNA clones coding for a member of the family of high mobility group proteins (HMG-T) in trout and analysis of HMG-T-mRNA's in trout tissues
(Oxford University Press, Oxford Journals, Great Clarendon Street, 1985-07)No abstract available. -
Nucleotide sequence of 5S rDNA and localization of the ribosomal RNA genes to metaphase chromosomes of the Tilapiine cichlid fish, Oreochromis niloticus
(2000-10)In this study, we report the cloning and nucleotide sequence of PCR-generated 5S rDNA from the Tilapiine cichlid fish, Oreochromis niloticus. Two types of 5S rDNA were detected that differed by insertions and/or deletions ... -
Can SINEs: A family of tRNA-derived retroposons specific to the superfamily canoidea
(1994)A repetitive element of approximately 200 bp was cloned from harbour seal (Phoca vitulina concolour) genomic DNA. The sequence of the element revealed putative RNA polymerase III control boxes, a poly A tail and direct ... -
Nucleotide sequence, genomic organization and evolution of a major repetitive DNA family in tilapia (Oreochromis mossambicus/hornorum )
(1989)A highly repetitive DNA sequence from tilapia (Oreochromis mossambicus/hornorum ) has been cloned and sequenced. It is a tandemly arrayed sequence of 237 bp and constitutes 7% of the fish genome. The copy number of the ... -
Tidal and turbidity effects on the shallow-water fish assemblage of Kuwait Bay
(1990)Effects of location, diel period, tidal condition and water clarity on the size and distribution of the shallow water fish assemblage of the non-estuarine Kuwait Bay, were investigated using a beach seine and a small ... -

Computer-Assisted Photo-Identification of Narwhals
(2011-09)Although the narwhal (Monodon monoceros) is economically and culturally important to northern residents, sound management of this species is impaired by large gaps in knowledge. Research on this species has been limited ... -
Behavioral reactions of northern bottlenose whales (Hyperoodon ampullatus) to biopsy darting and tag attachment procedures
(2001-04)The effects of invasive or intrusive research techniques need to be thoroughly documented in order to satisfy appropriate standards of animal care. How cetaceans react to either biopsy darting ol tag attachment procedures ... -
Inferring Animal Densities from Tracking Data Using Markov Chains
(2013-04)The distributions and relative densities of species are keys to ecology. Large amounts of tracking data are being collected on a wide variety of animal species using several methods, especially electronic tags that record ... -
Analysis of animal movement using opportunistic individual identifications: Application to sperm whales
(2001-05)Data sets in which animals are identified individually in different places and times may contain considerable information on movements. However, if the probability that an animal is reidentified depends on its movement ... -
Nonbreeding-Season Drivers of Population Dynamics in Seasonal Migrants: Conservation Parallels Across Taxa
(2009-12)For seasonal migrants, logistical constraints have often limited conservation efforts to improving survival and reproduction during the breeding season only. Yet, mounting empirical evidence suggests that events occurring ... -
Prey Exchange Rates and the Impact of Predators on Prey Populations in Streams
(1990)We present four lines of evidence that the magnitude of prey exchange (=immigration/emigration) among substrate patches has an overwhelming influence on the perceived effects of predators on prey populations. (1) An extensive ... -
Surviving historical Patagonian landscapes and climate: molecular insights from Galaxias maculatus
(2010-03)Background: The dynamic geological and climatic histories of temperate South America have played important roles in shaping the contemporary distributions and genetic diversity of endemic freshwater species. We use ... -
How quality of host plant affects a predator-prey interaction in biological control
(1995)In cases of successful biological control the pest population is maintained at low densities by a natural enemy, but the mechanisms by which the predator or parasitoid manages to control the pest are often unknown. This ... -
Estimation of Temporal Variability in Populations
(1995-10)A common measure of the temporal variability of a population is the standard deviation of the logarithms of successive estimated population sizes, In(D-t). This measure overestimates true temporal variability (the standard ... -
Patch Dynamics of a Phytophagous Mite Population Effect of Number of Subpopulations
(1991)I conducted a field test of the hypothesis that the dynamics of a predator-prey interaction should be affected by the number of interacting subpopulations within an assemblage. I used a "successful" biological control ... -
Intraguild interactions and large-scale population patterns
(2009-09)Competitive interactions, including interference and intraguild predation, occur in many aquatic food webs and influence large-scale patterns of abundance, especially in lentic habitats. In a study of small coastal streams ... -
Invertebrate predation and lotic prey communities: Evaluation of in situ enclosure/exclosure experiments
(1984)The influence of the stonefly Kogotus nonus on prey communities was assessed by varying the predator density within small enclosures in a first-order stream in southwestern Alberta. Experimental containers with natural ...
