Economics Of Cormorant Predation On Catfish Farms, Carole Engle, Ganesh Kumar, Terrel Christie, Brian S. Dorr, Brian Davis, Luke Roy, Anita Kelly

United States Department of Agriculture Wildlife Services: Staff Publications

The Double-crested Cormorant is the primary avian predator on catfish farms causing significant economic losses primarily due to 1) on-farm expenditures related to bird-management activities and 2) value of the catfish lost to cormorants. This comprehensive economic study quantified these two economic effects by surveying catfish farms in the delta regions of Mississippi and Arkansas. On-farm expenditures for bird scaring were used to quantify bird-management costs. Economic losses from fish consumed by cormorants were quantified by evaluating data from field studies of the abundance, distribution, and diet of cormorants in the Mississippi delta. This study found that catfish farmers …

Bovine Respiratory Microbiota Of Feedlot Cattle And Its Association With Disease, Jianmin Chai, Sarah F. Capik, Beth Kegley, John T. Richeson, Jeremy G. Powell, Jiangchao Zhao

Animal Science Faculty Publications and Presentations

Bovine respiratory disease (BRD), as one of the most common and costly diseases in the beef cattle industry, has significant adverse impacts on global food security and the economic stability of the industry. The bovine respiratory microbiome is strongly associated with health and disease and may provide insights for alternative therapy when treating BRD. The niche-specific microbiome communities that colonize the inter-surface of the upper and the lower respiratory tract consist of a dynamic and complex ecological system. The correlation between the disequilibrium in the respiratory ecosystem and BRD has become a hot research topic. Hence, we summarize the pathogenesis …

Observations On Regeneration Of The Pedipalp And Legs Of Scorpions, Martin Watz, Jason A. Dunlop

Euscorpius

An Opisthacanthus asper (Peters, 1861) (Hormuridae) shows a relatively rare example of pedipalp regeneration in which the lost tibia and tarsus was replaced by a smaller, curved element of uncertain homology to either the fixed or free finger. A comparable abnormal palp described in the literature hints that pedipalps can only regenerate a structure of this form, regardless of the site of amputation. An Olivierus caucasicus (Nordmann, 1840) (Buthidae) is described in which claws (pretarsus) of leg III regenerated directly at the distal end of the tibia, while in leg IV the claws regenerated at the end of a truncated …

(Lepidoptera: Plutellidae), Gilmar Da Silva Nunes, Thais Aparecida Vitoriano Dantas, Wennia Rafaelly Souza Figueiredo, Roberio De Oliveira, Jacinto De Luna Batista, Alessandra Marieli Vacari, Sergio Antonio De Bortoli

Turkish Journal of Zoology

Euborellia annulipes (Lucas) (Dermaptera: Anisolabididae) is reported as a potential predator of Plutella xylostella (L.) (Lepidoptera: Plutellidae). In this study, we aimed to investigate whether fourth instar larvae, 1 or 3-day-old pupae of P. xylostella are suitable food for the development and reproduction of E. annulipes. We evaluated the characteristics of the predation, development of each life stage, and reproduction of the predator, by comparing them with an artificial diet. The nymphs consumed larvae and pupae equally in the first instars, but, from the third to fifth, they consumed more larvae over pupae. Both males and females consumed more larvae …

High Temperatures Adversely Affect The Hoverfly Episyrphus Balteatus(Diptera: Syrphidae) Fitness And Aphid Prey Consumption, Gregoire Noel, Jessica Caetano, Solene Blanchard, Antoine Boullis, Frederic Francis

Turkish Journal of Zoology

Numerous studies have shown that an increase of environmental temperature could directly disturb insect larval development. Natural enemies of insect pests, particularly predators of aphid populations, are not spared. Following temperature predictions of Belgian climate change scenario, the goal of this study is to measure life-history traits, such as the mass, body length and aphid consumption (Acyrthosiphon pisum (Harris, 1776)) (Hemiptera: Aphididae) of Episyrphus balteatus (De Geer, 1776) (Diptera: Syrphidae) larvae under three constant temperature treatments (i.e. 20, 23, and 26 °C). We detected no significant differences between 20 °C and 23 °C on the hoverflies larval development, their aphidophagous …

Autophagic Chemicals Effect To Atg8 And Rice Stripe Virus Relative Expressions, And Wolbachia Relative Density In Laodelphax Striatellus (Hemiptera: Delphacidae), Achmad Gazali, Ardhiani Hidayanti, Yohsuke Tagami

Turkish Journal of Zoology

Laodelphax striatellus is one of the most important pest insects and vectors of rice stripe virus (RSV), which causes rice stripe disease (RSD) in rice plants. L. striatellus is infected by Wolbachia. RSV and Wolbachia may be regulated by a cell defense mechanism within insect cells called autophagy. We utilized autophagic chemicals to predict the relationships between Atg8 (an importance of autophagy-related genes), Wolbachia, and RSV within L. striatellus. The relative expressions and density level of Atg8, RSV, and Wolbachia were determined by three autophagy inducers and two inhibitors. We examined the effect of chemicals on the host. We report …

New Insights On The Impact Of Earthworm Extract On The Growth Of Beneficial Soil Fungi: Species-Specific Alteration Of The Nematophagous Fungal Growth And Limitation Of An Entomopathogenic Fungus, Maryam Chelkha, Lamia Yakkou, Sofia Houida, Mohamed Raouane, Souad Amghar, Raquel Campos-Herrera, Abdellatif El Harti

Turkish Journal of Zoology

Earthworms influence soil ecosystem functions such as decomposition and regulation of nutrient cycles by burrowing, feeding, or secreting their cutaneous excreta. Earthworms can also modulate soil biodiversity and their interactions. Recent research has revealed that earthworm feeding activity or excretions can alter the performance of entomopathogenic nematodes (EPNs) and entomopathogenic fungi (EPFs), known biological control agents. Still, the impact of earthworm cadavers on the growth and reproduction of other biological control agents such as nematophagous fungus (NFs) and EPFs has been poorly explored. We suggest that earthworm body tissue could be used as a food supply by certain fungal species. …

Free Will And Animal Suicide, Sabina Schrynemakers

Animal Sentience

David Peña-Guzmán presents two arguments against the view that because only humans have free will only humans can commit suicide: (1) nonhuman animals may possess free will, and (2) the libertarian notion of free will is incompatible with scientific explanation. The free will objection to animal suicide is indeed mistaken, but Peña-Guzmán’s criticism of the libertarian notion of free will seems misplaced. His target should instead be the assumption that free choices must be made consciously or self-reflectively or the assumption that freedom cannot come in degrees.

Pain Sentience Criteria And Their Grading, Eva Jablonka, Simona Ginsburg

Animal Sentience

On the basis of the target article by Crump and colleagues, we suggest a more parsimonious scheme for evaluating the evidence for sentience. Since some of the criteria used by Crump et al. are not independent and some are uninformative we exclude some criteria and amalgamate others. We propose that evidence of flexible learning and prioritization, in conjunction with relevant data on brain organization, is sufficient for assigning pain-sentience to an animal and we suggest a scoring scheme based on four criteria.

Truly Minimal Criteria For Animal Sentience, Mark Solms

Animal Sentience

The criteria for determining animal sentience proposed in the target article are sensible but they lack an explicit functional justification for the focus on pain. This commentary provides an abbreviated account of the most basic functional principles that underpin animal sentience and articulates some minimal criteria for determining its presence.

Fine-Tuning The Criteria For Inferring Sentience, Culum Brown

Animal Sentience

“Sentience” means the capacity to feel, and feelings are private affairs. Sentience is hence extremely difficult to quantify in nonhuman animals. We have no direct means of determining whether an animal is sentient. Thus we rely on a series of indirect measures or criteria which collectively provide some level of confidence about the probability that an animal is sentient. Crump et al. propose a modified framework based on 8 criteria for estimating the likelihood of sentience in a target taxon. Whereas I very much like their proposed framework, I would suggest a couple of amendments that may improve it further: …
