The First Certified Record Of The Endemic Fish Speciespachychilon Macedonicum (Steindachner, 1892) In A Lake Complex Outsideof Its Nominal Range, With Notes On Its Biological Features, Dimitra Bobori, Olga Petriki, Emmanouel Tsakoumis Jan 2016

The First Certified Record Of The Endemic Fish Speciespachychilon Macedonicum (Steindachner, 1892) In A Lake Complex Outsideof Its Nominal Range, With Notes On Its Biological Features, Dimitra Bobori, Olga Petriki, Emmanouel Tsakoumis

Turkish Journal of Zoology

The cyprinid Pachychilon macedonicum (Steindachner, 1892) is a species that is endemic to the southern Balkan Peninsula with limited distribution in Greece. Here we confirm the species' expansion and establishment in a complex of 4 lakes located outside of its currently known distribution range and provide, for the first time, some of its biological features. The species' presence was certified in 3 (Vegoritida, Petron, Chimaditida; northern central Greece) of the 4 lakes studied (Lake Zazari was also sampled), which now constitute a new western limit for its distribution in Greece. Pachychilon macedonicum specimens in Lake Vegoritida were longer (mean length: …

Contribution To The Knowledge Of Fish Fauna Of Kosovo With A Special Note On Some Invasive Species, Agim Gashi, Emine Shabani, Linda Grapci Kotori, Kemajl Bislimi, Qenan Maxhuni, Halil Ibrahimi

Turkish Journal of Zoology

Despite the long tradition of ichthyofaunal research in the Balkan Peninsula, there are still poorly investigated areas. Kosovo is one of the least investigated countries of the Balkan Peninsula in regard to fish fauna. In this study, we present the results of a fish fauna investigation in Badovc Lake and the Llap River. The fish fauna of Badovc Lake in central Kosovo was investigated at monthly intervals between June 2012 and December 2012. A total of 16 species belonging to 6 families, Cyprinidae, Cobitidae, Percidae, Siluridae, Esocidae, and Centrarhidae, were determined in this research area. The vast majority of species …

Dung Beetles (Coleoptera: Scarabaeidae) Utilizing Water Buffalo Dungon The Black Sea Coast Of Turkey, Gregory Thomas Sullivan, Sebahat Sullivan, Jean-Pierre Lumaret, Greg Baxter, Myron Zalucki, Ünal Zeybekoğlu Jan 2016

Dung Beetles (Coleoptera: Scarabaeidae) Utilizing Water Buffalo Dungon The Black Sea Coast Of Turkey, Gregory Thomas Sullivan, Sebahat Sullivan, Jean-Pierre Lumaret, Greg Baxter, Myron Zalucki, Ünal Zeybekoğlu

Turkish Journal of Zoology

There have been few ecological studies of dung beetles (Coleoptera: Scarabaeidae) from the Black Sea Region of Turkey. In the RAMSAR-listed wetland system of the Kızılırmak Delta of Turkey's central Black Sea coast, seasonal grazing by domesticated water buffalo produces plentiful dung from April to November. Twenty-three species of dung beetles from 13 genera of Aphodiinae and 4 genera of Scarabaeinae were collected from their dung on two adjacent soil types in 2013. The species were from three functional groups, namely dung dwelling (12), tunneling (10), and ball rolling (1). Thirteen and fourteen species were collected in spring/summer and autumn, …

An Update Note On Diversity And Conservation Of The Endemic Fishes In Iranian Inland Waters, Azad Teimori, Hossein Mostafavi, Hamid Reza Esmaeili Jan 2016

An Update Note On Diversity And Conservation Of The Endemic Fishes In Iranian Inland Waters, Azad Teimori, Hossein Mostafavi, Hamid Reza Esmaeili

Turkish Journal of Zoology

The diversity, distribution pattern, and conservation status of endemic species were obtained by analysis of catalogued specimens collected by fieldwork carried out by the authors at various times in different regions in Iran since 2002. The Iranian endemic ichthyofauna includes 51 species and forms a significant part of the total species known from this country, so that new endemic species are being described almost every year. The highest endemicity is found in the Tigris-Karoun basin in the west, followed by the Kor River and the Persian Gulf basins in the south. Creation of the landlocked basins played an important role …

Morphological Characteristics Of The Elusive Blotched Snake (Elaphe Sauromates)At Its Northwestern Range Limit (Romania), Tiberiu Sahlean, Alexandru Strugariu, Paul Dinca, Gabriel Chişamera, Catalin Stanciu, Ştefan Zamfirescu, Iulian Gherghel, Valentina Moraru Jan 2016

Morphological Characteristics Of The Elusive Blotched Snake (Elaphe Sauromates)At Its Northwestern Range Limit (Romania), Tiberiu Sahlean, Alexandru Strugariu, Paul Dinca, Gabriel Chişamera, Catalin Stanciu, Ştefan Zamfirescu, Iulian Gherghel, Valentina Moraru

Turkish Journal of Zoology

The blotched snake (Elaphe sauromates) is one of the most elusive species of snakes in Romania, and only a small number of individuals have ever been found, which is why morphological data are both scarce and over half a century old. The data gathered from the individuals captured during our field work confirmed the presence of sexual dimorphism (significant for SVL/TL ratios) and presented a greater morphological variation than recorded in the scientific literature. Individuals examined usually had more than 2 rows of temporal scales and displayed variation in subocular scales, as opposed to the information previously available, hinting at …

First Record Of The Invasive Vinegar Fly Drosophila Suzukii (Matsumura)(Diptera: Drosophilidae) From Eastern Turkey, Alper Orhan, Rafet Aslantaş, Banu Şebnem Önder, Göksel Tozlu Jan 2016

First Record Of The Invasive Vinegar Fly Drosophila Suzukii (Matsumura)(Diptera: Drosophilidae) From Eastern Turkey, Alper Orhan, Rafet Aslantaş, Banu Şebnem Önder, Göksel Tozlu

Turkish Journal of Zoology

Drosophila suzukii (Matsumura, 1931) (Diptera: Drosophilidae) is native to East Asia and invasive on the European and American continents. The first records in both Europe and the United States were in 2008. Since that year, it has widely moved across these continents. As D. Suzukii females lay eggs in healthy ripening fruits of several species, particularly in small soft fruits and berries, the species causes agricultural damage. The soft thin-skinned fruit pest, identified as D. Suzukii, has been found in Erzurum, Turkey, where damaged strawberry crops were observed and cultured in the middle of August and September 2014. Initially, 2 …

Pain And Fish Welfare, Eliane Gonçalves-De-Freitas Jan 2016

Pain And Fish Welfare, Eliane Gonçalves-De-Freitas

Animal Sentience

The evolutionary approach of Key’s (2016) target article, generically comparing humans with fish of all kinds, is simplistic. The author ignores published research on structural and molecular aspects of pain in fish. The target article reads more like a selective polemic against fish welfare than an even-handed analysis.

Brain Processes For “Good” And “Bad” Feelings: How Far Back In Evolution?, Jaak Panksepp Jan 2016

Brain Processes For “Good” And “Bad” Feelings: How Far Back In Evolution?, Jaak Panksepp

Animal Sentience

The question of whether fish can experience pain or any other feelings can only be resolved by neurobiologically targeted experiments. This commentary summarizes why this is essential for resolving scientific debates about consciousness in other animals, and offers specific experiments that need to be done: (i) those that evaluate the rewarding and punishing effects of specific brain regions and systems (for instance, with deep-brain stimulation); (ii) those that evaluate the capacity of animals to regulate their affective states; and (iii) those that have direct implications for human affective feelings, with specific predictions — for instance, the development of new treatments …

Dale Bishop, Donald R. Deis, Donna Devlin, A. Randall Hughes, John J. Hutchens, Jr., Whitney M. Kiehn, Caroline R. Mcfarlin, Clay L. Montague, Sean P. Powers, C. Edward Proffitt, Nicholle Rutherford, Camille L. Stagg, Keith Walters

University Faculty and Staff Publications

Marine species with planktonic larvae often have high spatial and temporal variation in recruitment that leads to subsequent variation in the ecology of benthic adults. Using a combination of published and unpublished data, we compared the population structure of the salt marsh snail, Littoraria irrorata, between the South Atlantic Bight and the Gulf Coast of the United States to infer geographic differences in recruitment and to test the hypothesis that the Deepwater Horizon oil spill led to widespread recruitment failure of L. irrorata in Louisiana in 2010. Size-frequency distributions in both ecoregions were bimodal, with troughs in the distributions consistent …

Intertemporal Similarity: Discounting As A Last Resort, Jeffrey R. Stevens Jan 2016

Intertemporal Similarity: Discounting As A Last Resort, Jeffrey R. Stevens

Jeffrey Stevens Publications

Standard models of intertemporal choice assume that individuals discount future payoffs by integrating reward amounts and time delays to generate a discounted value. Alternative models propose that, rather than integrate across them, individuals compare within attributes (amounts and delays) to determine if differences in one attribute outweigh differences in another attribute. For instance, Leland (2002) and Rubinstein (2003) propose models that 1) compare the two reward amounts to determine whether they are similar, 2) compare the similarity of the two time delays, and then 3) make a decision based on these similarity judgments. Here, I tested discounting models against attribute-based …

Cognitive Phenotypes And The Evolution Of Animal Decisions, Tamra C. Mendelson, Courtney L. Fitzpatrick, Mark E. Hauber, Charles H. Pence, Rafael L. Rodriguez, Rebecca J. Safran, Caitlin A. Stern, Jeffrey R. Stevens Jan 2016

Cognitive Phenotypes And The Evolution Of Animal Decisions, Tamra C. Mendelson, Courtney L. Fitzpatrick, Mark E. Hauber, Charles H. Pence, Rafael L. Rodriguez, Rebecca J. Safran, Caitlin A. Stern, Jeffrey R. Stevens

Jeffrey Stevens Publications

Despite the clear fitness consequences of animal decisions, the science of animal decision making in evolutionary biology is underdeveloped compared with decision science in human psychology. Specifically, the field lacks a conceptual framework that defines and describes the relevant components of a decision, leading to imprecise language and concepts. The ‘judgment and decision-making’ (JDM) framework in human psychology is a powerful tool for framing and understanding human decisions, and we apply it here to components of animal decisions, which we refer to as ‘cognitive phenotypes’. We distinguish multiple cognitive phenotypes in the context of a JDM framework and highlight empirical …

United States Army Corps of Engineers, Omaha District

Life-history characteristics of age-0 sturgeon chub Macrhybopsis gelida, shoal chub Macrhybopsis hyostoma and sicklefin chub Macrhybopsis meeki were compared using several methods. All Macrhybopsis species consumed mostly midge pupae, but M. meeki had the most general diet (Levins’ index, B=0⋅22) compared with M. hyostoma (B=0⋅02) and M. gelida (B=0⋅09). Morisita’s diet overlap index among species pairs ranged from 0⋅62 to 0⋅97 and was highest between M. hyostoma and M. gelida. Daily ages estimated from lapilli otoliths for each species ranged from 15 to 43 days for M. gelida, 19 to 44 for …

Differential Wolf-Pack-Size Persistence And The Role Of Risk When Hunting Dangerous Prey, Shannon M. Barber-Meyer, L. David Mech, Wesley E. Newton, Bridget L. Borg Jan 2016

Differential Wolf-Pack-Size Persistence And The Role Of Risk When Hunting Dangerous Prey, Shannon M. Barber-Meyer, L. David Mech, Wesley E. Newton, Bridget L. Borg

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Risk to predators hunting dangerous prey is an emerging area of research and could account for possible persistent differences in gray wolf (Canis lupus) pack sizes. We documented significant differences in long-term wolf-pack-size averages and variation in the Superior National Forest (SNF), Denali National Park and Preserve, Yellowstone National Park, and Yukon, Canada (p < 0.01). The SNF differences could be related to the wolves’ risk when hunting primary prey, for those packs (N = 3) hunting moose (Alces americanus) were significantly larger than those (N = 10) hunting white-tailed deer (Odocoileus virginianus) (F1,8 = 16.50, p = 0.004). Our data support the hypothesis that differential pack-size persistence may be …

Identification Of Taenia Metacestodes From Mongolian Mammals Using Multivariate Morphometrics Of The Rostellar Hooks, Danielle M. Tufts, Nyamsuren Batsaikhan, Michael Pitner, Gábor R. Rácz, Altangerel Tsogtsaikhan Dursahinhan, Scott Lyell Gardner Jan 2016

Identification Of Taenia Metacestodes From Mongolian Mammals Using Multivariate Morphometrics Of The Rostellar Hooks, Danielle M. Tufts, Nyamsuren Batsaikhan, Michael Pitner, Gábor R. Rácz, Altangerel Tsogtsaikhan Dursahinhan, Scott Lyell Gardner

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

Parasite diversity in and among various species of mammals within Mongolia is still poorly understood. The current paper focusses on a small part of the results of the Mongolian Vertebrate Parasite Project (MVPP), which entailed a broad-scale biodiversity survey of the vertebrates and their parasites of the Gobi and Altai regions of Mongolia. We report on the prevalence and morphological variation of larval cestodes of the family Taeniidae that occurred in small mammals that were collected from 2009-2012 from various locations in southern Mongolia. From these metacestodes, we studied both large and small rostellar hooks and analyzed both size and …

Fishing Diseased Abalone To Promote Yield And Conservation, Tal Ben-Horin, Kevin D. Lafferty, Gorka Bidegain, Hunter S. Lenihan Jan 2016

Fishing Diseased Abalone To Promote Yield And Conservation, Tal Ben-Horin, Kevin D. Lafferty, Gorka Bidegain, Hunter S. Lenihan

United States Geological Survey: Staff Publications

Past theoretical models suggest fishing disease-impacted stocks can reduce parasite transmission, but this is a good management strategy only when the exploitation required to reduce transmission does not overfish the stock. We applied this concept to a red abalone fishery so impacted by an infectious disease (withering syndrome) that stock densities plummeted and managers closed the fishery. In addition to the non-selective fishing strategy considered by past disease- fishing models, we modelled targeting (culling) infected individuals,which is plausible in red abalone because modern diagnostic tools can determine infection without harming landed abalone and the diagnostic cost is minor relative to …

Wind Energy Development: Methods For Assessing Risks To Birds And Bats Pre-Construction, Todd Katzner, Victoria Bennett, Tricia Miller, Adam Duerr, Melissa Braham, Amanda Hale Jan 2016

Wind Energy Development: Methods For Assessing Risks To Birds And Bats Pre-Construction, Todd Katzner, Victoria Bennett, Tricia Miller, Adam Duerr, Melissa Braham, Amanda Hale

Human–Wildlife Interactions

Wind power generation is rapidly expanding. Although wind power is a low-carbon source of energy, it can impact negatively birds and bats, either directly through fatality or indirectly by displacement or habitat loss. Pre-construction risk assessment at wind facilities within the United States is usually required only on public lands. When conducted, it generally involves a 3-tier process, with each step leading to more detailed and rigorous surveys. Preliminary site assessment (U.S. Fish and Wildlife Service, Tier 1) is usually conducted remotely and involves evaluation of existing databases and published materials. If potentially at-risk wildlife are present and the developer …

A Conceptual Model To Determine Vulnerability Of Wildlife Populations To Offshore Wind Energy Development, M. Wing Goodale, Iain J. Stenhouse Jan 2016

A Conceptual Model To Determine Vulnerability Of Wildlife Populations To Offshore Wind Energy Development, M. Wing Goodale, Iain J. Stenhouse

Human–Wildlife Interactions

As offshore wind energy development is planned in the United States, there is an increasing need for pre- and post-construction monitoring plans to be focused on species determined to be most vulnerable to hazards of a specific project. We propose a conceptual model that incorporates biological and sociological parameters. Specifically, we suggest that demographic, ethological/biological, and population sensitivity be considered with legal protection, economic importance, and/or stakeholder interest. We recommend that vulnerability determinations include qualitative and quantitative methods.

Visual And Olfactory Concealment Of Duck Nests: Influence On Nest Site Selection And Success, Jennifer S. Borgo, Michael R. Conover Jan 2016

Visual And Olfactory Concealment Of Duck Nests: Influence On Nest Site Selection And Success, Jennifer S. Borgo, Michael R. Conover

Human–Wildlife Interactions

Selecting a nest site is an important decision for waterfowl. Because most nest failure is due to depredation, the primary selective pressure in choosing a nest site should be to reduce depredation risk. This task is difficult, however, because predators use differing tactics to locate nests, such as olfactory or visual cues. The purpose of this research was to evaluate both the olfactory and visual components of waterfowl nest site selection and nest depredation in North Dakota. We located waterfowl nests, monitored them until termination (hatched or depredated), and collected both visual and olfactory concealment characteristics of nest sites and …

Wind Energy Development: Methods To Assess Bird And Bat Fatality Rates Post-Construction, Manuela Huso, Dan Dalthorp, T. J. Miller, Dawn Bruns

Human–Wildlife Interactions

Monitoring fatalities at wind energy facilities after they have been constructed can provide valuable information regarding impacts of wind power development on wildlife. The objective of this monitoring is to estimate abundance of a super-population of carcasses that entered the area within a designated period of time. By definition, the population is not closed and carcasses can enter as they are killed through collision with turbines, and leave as they are removed by scavengers or decompose to a point where they are not recognizable. In addition, the population is not inherently mobile, but can only change location through some external …

Opinion The “Non-Native” Enigma, Danny Caudill, Gretchen Caudill Jan 2016

Opinion The “Non-Native” Enigma, Danny Caudill, Gretchen Caudill

Human–Wildlife Interactions

Non-native species have been introduced to ecosystems throughout the world, and in some instances, have degraded the invaded system. Consequently, the distinction between native and non-native species has become an integral component of conservation planning. Recently however, the conservation value of the distinction has been questioned. We examine how the native versus non-native dichotomy is intrinsically ambiguous, which therefore limits the conservation utility of the designation in and of itself. A large degree of uncertainty exists as to whether many species are or are not native. Measures outside the non-native dichotomy (e.g., impacts, evolutionary ecology, paleontology) could better inform conservation …

Impact Of Sagebrush Nutrients And Monoterpenes On Greater Sage-Grouse Vital Rates, Brian R. Wing, Terry A. Messmer Jan 2016

Impact Of Sagebrush Nutrients And Monoterpenes On Greater Sage-Grouse Vital Rates, Brian R. Wing, Terry A. Messmer

Human–Wildlife Interactions

Greater sage-grouse (Centrocercus urophasianus; sage-grouse) depend on sagebrush (Artemisia spp.) to complete its annual life cycle. The winter diet for sage-grouse consists almost entirely of sagebrush leaves, and individual birds may gain weight while foraging on sagebrush. Previous studies have reported higher crude protein and lower monoterpene concentrations in the sagebrush species selected as winter forage by sagegrouse. However, no studies have attempted to link female sage-grouse vital rates (i.e., nest initiation and success, egg fertility, clutch size, and adult survival) to crude protein or monoterpene concentrations of sagebrush plants browsed during pre-nesting periods. From March …

Declining Populations Of Greater Sage-Grouse: Where And Why, Michael R. Conover, Anthony J. Roberts Jan 2016

Declining Populations Of Greater Sage-Grouse: Where And Why, Michael R. Conover, Anthony J. Roberts

Human–Wildlife Interactions

Scientists have been predicting the extinction of greater sage-grouse (Centrocercus urophasianus) since 1916, and sage-grouse populations have declined relentlessly during the last century despite attempts to reverse the decline. In this review paper, we examined the scientific literature to evaluate hypotheses about why sage-grouse populations have declined. There is little support for the hypotheses that the decline is due to overhunting, parasites, food shortages, or collisions with power lines or fences. West Nile Virus (WNV) reduced sagegrouse up to 25% when the virus first reached the West during 2002, but sage-grouse have developed resistance to the virus since …

Economic Utility For The Anthropogenic Spread Of Wild Hogs, Joe N. Caudell, Emily Dowell, Katelyn Welch Jan 2016

Economic Utility For The Anthropogenic Spread Of Wild Hogs, Joe N. Caudell, Emily Dowell, Katelyn Welch

Human–Wildlife Interactions

Wild hogs (Sus scrofa) are an invasive, exotic species that has spread through much of the United States through anthropogenic means. Many states have laws and regulations with the intent of preventing the illegal importation, introduction, and establishment of wild swine populations. However, in many cases, these laws have been ineffectual at stopping the anthropogenic spread of wild swine. To assess the risk for moving wild hogs, we examined various wild hog-related laws throughout the United States and assessed the potential reward for their illegal movement of releasing hogs for hunting purposes. We found that fines ranged from …

Grizzly Bear Space Use, Survival, And Persistence In Relation To Human Habitation And Access, Bogdan Cristescu, Gordon B. Stenhouse, Bernie Goski, Mark S. Boyce Jan 2016

Grizzly Bear Space Use, Survival, And Persistence In Relation To Human Habitation And Access, Bogdan Cristescu, Gordon B. Stenhouse, Bernie Goski, Mark S. Boyce

Human–Wildlife Interactions

Previous studies showed that the likelihood of a bear becoming a nuisance and thus being removed from a population (i.e., relocated or killed) depends on numerous factors such as natural food supply, sex, age, and reproductive status. Distances from a bear’s home range and activity centers to conflict zones such as towns, roads, and trails used by humans also affect the incidence of nuisance behavior and have been documented for grizzly/brown bears (Ursus arctos) in North America and Europe. But those studies did not quantify the relative influences by various factors on distance from conflict zones, or the …

Canine Brucellosis In Turkey From An Environmental Perspective, Uçkun Sai̇t Uçan

Turkish Journal of Veterinary & Animal Sciences

Brucellosis is a zoonotic disease that affects not only livestock with economical losses but also human beings by causing serious health problems worldwide. Canine brucellosis has largely been overlooked in the world. In Turkey, brucellosis has also been one of the major concerns for decades. Canine brucellosis in this country has been reviewed and discussed from an environmental perspective in this review. As a part of prevention measures, one of the urgent practices that should be applied is to expand the routine examinations to include serological testing for all animals on arrival to kennels and then to decide the fate …
