Fisheries Management Paper No.283 - Abalone Resource Of Western Australia Harvest Strategy 2106 - 2021, Department Of Fisheries Western Australia

Fisheries Management Papers

Harvest strategies for aquatic resources managed by the Western Australian Department of Fisheries (the Department) are formal documents prepared to support the decision-making processes required to ensure the management of these resources are consistent with the principles of Ecologically Sustainable Development (ESD). The objectives of ESD are reflected in the objects of the Fish Resources Management Act 1994 (FRMA) and Section 9 of the Aquatic Resources Management Act, which will replace the FRMA once proclaimed.

The publication of these strategies is intended to make the decision-making considerations and processes for the management of specified aquatic resources publicly transparent and provide …

Cyanomargarita Gen. Nov. (Nostocales, Cyanobacteria): Convergent Evolution Resulting In, Jeffrey R. Johansen, Sergei Shalygin, Regina Shalygina, Nicole Pietrasiak

2017 Faculty Bibliography

Two populations of Rivularia‐like cyanobacteria were isolated from ecologically distinct and biogeographically distant sites. One population was from an unpolluted stream in the Kola Peninsula of Russia, whereas the other was from a wet wall in the Grand Staircase‐Escalante National Monument, a desert park‐land in Utah. Though both were virtually indistinguishable from Rivularia in field and cultured material, they were both phylogenetically distant from Rivularia and the Rivulariaceae based on both 16S rRNA and rbcLX phylogenies. We here name the new cryptic genus Cyanomargarita gen. nov., with type species C. melechinii sp. nov., and additional species C. calcarea …

A Revision Of The Genus Geitlerinema And A Description Of The Genus Anagnostidinema Gen. Nov. (Oscillatoriophycidae, Cyanobacteria), Jeffrey R. Johansen, Otakar Strunecký, Markéta Bohunická, Kateřina Čapková Čapková, Lenka Raabová, Petr Dvořák, Jiří Komárek

2017 Faculty Bibliography

The simple filamentous cyanobacterial genus Geitlerinema is heterogeneous. At least two distinct phylogenetic clades can be derived from the set of most common freshwater Geitlerinema species. Our revision is based on the original description of the type species G. splendidum aka Oscillatoria spendida and on molecular sequencing of morphologically relevant strains. The revised Geitlerinema contains only one species according to morphological similarity with its original description. Consequently, the majority of other freshwater species inferred from molecular sequencing of 16S rRNA gene and 16S–23S ITS analysis (related both genetically and morphologically to G. pseudacutissimum) must be classified as a special taxon …

Hovering In The Heat: Effects Of Environmental Temperature On Heat Regulation In Foraging Hummingbirds, Don R. Powers, Kathleen M. Langland, Susan M. Wethington, Sean D. Powers, Catherine H. Graham, Bret W. Tobalske

Faculty Publications - Department of Biological & Molecular Science

At high temperature (greater than 40°C) endotherms experience reduced passive heat dissipation (radiation, conduction and convection) and increased reliance on evaporative heat loss. High temperatures challenge flying birds due to heat produced by wing muscles. Hummingbirds depend on flight for foraging, yet inhabit hot regions. We used infrared thermography to explore how lower passive heat dissipation during flight impacts body-heat management in broad-billed (Cynanthus latirostris, 3.0 g), black-chinned (Archilochus alexandri, 3.0 g), Rivoli’s (Eugenes fulgens, 7.5 g) and blue-throated (Lampornis clemenciae, 8.0 g) hummingbirds in southeastern Arizona and calliope hummingbirds (Selasphorus calliope, 2.6 g) in Montana. Thermal gradients driving passive …

Within-Wing Isotopic (Δ2h, Δ13c, Δ15n) Variation Of Monarch Butterflies: Implications For Studies Of Migratory Origins And Diet, Keith A. Hobson, Tessa Plint, Eligio García Serrano, Xiomara Mora Alvarez, Isabel Ramirez, Fred J. Longstaffe

Earth Sciences Publications

Increasingly, stable isotope measurements are being used to assign individuals to broad geographic origins based on established relationships between animal tissues and tissue-specific isoscapes. In particular, the eastern North American population of the monarch butterfly (Danaus plexippus) has been the subject of several studies using established δ²H and δ¹³C wing-tissue isoscapes to infer natal origins of migrating and overwintering individuals. However, there has been no study investigating potential variance that can derive from sub-sampling different regions of the wings, especially those regions differing in pigmentation (orange versus black). Within-wing isotopic (δ²H, …

Stable Isotope Investigation Of The Migratory Behavior Of Silverhaired Bats (Lasionycteris Noctivagans) In Eastern North America, Erin E. Fraser, Darin Brooks, Fred J. Longstaffe

Earth Sciences Publications

We investigated the migratory movements of silver-haired bats (Lasionycteris noctivagans) across the eastern extent of the species’ range. We conducted stable hydrogen isotope analysis of fur samples (δ²H_fur) from museum specimens collected across latitudes and at all times of the year. We first used these data to estimate the timing of fur replacement and to develop a model associating δ²H_fur with that of local precipitation (δ²H_precip) at the location where fur replacement occurred. We then used this model to 1) identify individuals that had migrated …

The Effect Of Site Characteristics On The Reproductive Output Of Lesser Celandine (Ranunculus Ficaria), Justin P. Kermack

ETD Archive

Ranunculus ficaria L., an ephemeral perennial invasive plant brought over from Europe, is becoming widespread throughout the Northeastern United States. This herbaceous buttercup is able to create extensive dense mats that limit native species growth. Taking advantage of an early growing season and rapid reproduction rates, this species can create dense monocultures, which threatens native communities and ecosystems. Elimination of native spring ephemerals results in decreased biodiversity. A better understanding of how R. ficaria responds to site characteristics is needed to prioritize management efforts toward high-risk sites.

Ranunculus ficaria abundance and reproductive output (seed, bulbil and tuber production rates) were …

Geographic Distribution: Acrantophis Dumerili (Duméril’S Madagascan Ground Boa). Usa. Florida., Louis A. Somma, Kenneth L. Krysko, Laurence L. Conner

Papers in Herpetology

The geographic distribution of Acrantophis dumerili, a nonindigenous introduced species in Florida, with new records, is presented.

Acrantophis dumerili is indigenous to southern and southwestern Madagascar. We provide the first vouchers for Miami-Dade and Bay counties, which were likely escaped or released pets. Florida already has three established species of booid snakes (one boa, two pythons), all introduced through the pet trade pathway. Although there is no clear evidence for an established population of A. dumerili in Florida at this time, the Bay County individuals in a rural area in the Florida panhandle are a particular concern given that two …

The Status Of Two Species Of Nonindigenous Lizards In Florida, The Slender Chameleon, Chamaeleo Gracilis Hallowell 1842 And White-Lined Chameleon, Furcifer Lateralis (Gray 1831): A Corrigendum., Kenneth L. Krysko, Louis A. Somma

Papers in Herpetology

Krysko et al. (2016) recently published a summary of all known verified introductions of nonindigenous amphib­ians and reptiles in Florida, USA. Herein, we correct the iden­tity tity of one species and include an additional new record of a nonindigenous chameleon in Florida.

Krysko et al. (2016) reported the presence of a White-lined Chameleon, Furcifer lateralis (Gray 1831). In fact, this was a misidentified Slender Chameleon, Chamaeleo gracilis Hallowell 1842 (C. Anderson, pers. comm. 2016). Discussion and reference to F. lateralis in Krysko et al. (2016) and all associated data (UF voucher number, locality, collector, and collection date, including Table 1, …

Relationship Between Zooplankton And Walleye Rearing Pond Success, Danny Tuckett

Journal of Earth and Life Science

Walleye Sander vitreus are an important sport fish in Minnesota. This has led to the raising of Walleye in ponds to later be stocked into lakes. This study was done to determine the relationship between Walleye prey (zooplankton) and the success of Walleye in 11 stocked ponds in the Ortonville, MN area. There was no management of the ponds until harvest, which starts in late September and ends in November. There were significant positive relationships between rotifer density (P = 0.03) and nauplii density (P = 0.04) to kg of Walleye harvested. The setting where nauplii and rotifer density are …

Climate Dynamics, Invader Fitness, And Ecosystem Resistance In An Invasion-Factor Framework, Stephen L. Young, David R. Clements, Antonio Ditommaso

West Central Research and Extension Center, North Platte

As researchers and land managers increasingly seek to understand plant invasions and the external (climate) and internal (plant genetics) conditions that govern the process, new insight is helping to answer the elusive question of what makes some invasions successful and others not. Plant invasion success or failure is based on a combination of evolutionary and ecological processes. Abiotic (e.g., climate) and biotic (e.g., plant competition) conditions in the environment and plant genetics (e.g., fitness) combine in either decreasing or increasing invasion, yet it has proven challenging to know exactly which of these conditions leads to success for a given species, …

Beyond Precision Weed Control: A Model For True Integration, Stephen L. Young

West Central Research and Extension Center, North Platte

Precision means being exact and accurate and is an important management component for cropping systems. However, precision does not mean integration, which encompasses spatial and temporal dimensions and is a necessary practice rivaling precision. True IWM merges precision and integration by incorporating advanced technology that allows for greater flexibility of inputs and enhanced responsiveness to field conditions. Examples of this approach are non-existent due to a lack of suitable technological tools and a need for a paradigm shift. Herein a potential model startup company is offered as a guide to advance beyond precision weed control to true integration. The critical …

Effect Of Biochar Type And Size On In Vitro Rumen Fermentation Of Orchard Grass Hay, Zach D. Mcfarlane, Phillip R. Myer, Emily R. Cope, Neil D. Evans, T. Carson Bone, Bryan E. Bliss, J. Travis Mulliniks

West Central Research and Extension Center, North Platte

Biochar, a byproduct from the biofuels industry, may be a potential feed additive in ruminant diets due to possible improvements in microbial fermentation. Therefore, the objective of this study was to determine the nutritive value, in vitro digestibility, volatile fatty acid (VFA) production, and gas production of biochar inclusion to an orchard grass (Dactylis glomerata) basal diet. The study was designed as a 3 × 2 factorial arrangement with 3 different biochar sources and 2 biochar processed sizes as the main effects factors. Experimental treatments were biochar from 3 different tree types: 1) Chestnut Oak (Quercus prinus …

Minnesota Fish Taxonomic Key 2017 Edition, Warren Lamb

Journal of Earth and Life Science

Minnesota’s landscape is maze of lakes and river that are home to a recorded total of 163 species of fish. This document is a complete and current dichotomous taxonomic key of the Minnesota fishes. This key was based on the 1972 “Northern Fishes” key (Eddy 1972), and updated based on Dr. Jay Hatch’s article “Minnesota Fishes: Just How Many Are There?” (Hatch 2016). Any new species or family additions were also referenced to the 7th edition of the American Fisheries society “Names of North American Fishes” (Page et al. 2013) to assess whether a fish species is currently recognized by …

Self, Death, And Suicide: Does An Animal Know Of These?, Carolyn A. Ristau

Animal Sentience

Peña-Guzmán makes a strong case, using examples from the media and scientific literature, that many captive animals suffer severely. In examining the possibility of animal suicide, he dismisses the need for “reflective self-subjectivity” and “intent” in suicidal behavior. He claims that at least some animals understand “death,” citing examples of behavior he deems to be death “rituals.” But these can be more simply interpreted. The possibility of animal suicide remains more dubious than Peña-Guzmán suggests.

Changes In Behavior And Emotion Under Chicken Domestication, Martin Johnsson

Fates Of Ovules In Groundplum Milk-Vetch (Astragalus Crassicarpus Nutt.) In South Dakota, Arvid Boe, Paul J. Johnson

Native Plant Focused Publications

Groundplum milk-vetch (Astragalus crassicarpus Nutt.) is a native legume found on gravelly to sandy prairie uplands throughout central North America. The large and fleshy fruits, or pods, of this species were consumed by indigenous people and European settlers, and are cached by rodents. Our previous research on native legumes of the northern Great Plains indicated seed predation by insects, notably bruchid beetles belonging to the genus Acanthoscelides Schilsky, was a dominant factor determining viable seed production in natural and artificial plant assemblages. However, although we have studied the reproductive biology of several species of Astragalus L., none had fleshy pods. …

Meta-Analysis Of The Origin Of Bimaturism In Orangutan Males, Mina Adnan

UROP Posters

Unlike any other primate species, orangutans exhibit extraordinary sexual differences in their facial morphology. Two different strategies are available for males that reach sexual maturity: either become fully “flanged” and develop secondary sexual characteristics, which is knownto be only developed by the dominant male, or remain “unflanged” and not develop secondary sexual characteristics. The mechanism for how this bimaturism evolved and how occurs is poorly understood, but both flanged and unflanged males are reproductively successful.

This project explores the physiological mechanism behind bimaturismin orangutan males; namely, are there genetic differences between flanged and unflanged males such that the strategy is …

Experiment Versus Analogy In The Search For Animal Sentience, Geoffrey Hall

Animal Sentience

Deciding between rival accounts of an instance of an animal’s behavior can frequently be achieved by experimental tests of different predictions made by the alternatives. When, however, one (or both) of the alternatives is expressed in terms of the mental state of the animal, an experimental test to distinguish them can be hard to find. Although it is unsatisfactory in many ways, it may be necessary to fall back on argument from analogy with human behavior and experience.

Cognitive Continuity In Cognitive Dissonance, David R. Brodbeck, Madeleine I. R. Brodbeck

Animal Sentience

Zentall’s (2016) model of cognitive dissonance is compatible with cognitive continuity between humans and nonhumans. It may help explain cognitive dissonance-like behavior in many species, including humans. It is also consistent with Tinbergen’s (1963) ‘four whys’ in ethological explanation.

Review Of Bird Brain: An Exploration Of Avian Intelligence By Nathan Emery, Alan B. Bond

Avian Cognition Papers

Over the past 30 years, the study of bird behavior has been completely transformed by the ongoing revolution in cognitive psychology, opening up wholly new perspectives on the mental processes underlying such areas as foraging decisions, social intelligence, problem solving, memory encoding, and communication. Although these studies have contributed to a number of recent popular books, until now there has been no attempt to integrate avian cognition and recent findings in avian neuroanatomy and endocrinology into a single account that is attractive and accessible to a general readership. It is a steep challenge, but Nathan Emery has undertaken it in …

Neural Circuitry For Target Selection And Action Selection In Animal Behavior, Daizaburo Shizuka, Eileen Hebets, Kim L. Hoke

Papers in Behavior in Biological Sciences

Animal behaviorists have long strived for a comprehensive understanding of the proximate and ultimate causes of complex behavior, and we propose that recent advances in neurobiology can help reshape or clarify this behavior-oriented understanding. We begin with an overview of current views of neural circuit mechanisms that mediate target selection and action selection. In target selection, different stimuli compete for priority in sensory-motor process- ing. Action selection is the process by which multiple possible motor actions compete for priority in a manner which balances the needs of the animal with opportunities or threats in the environment. We next discuss spatial …
