Mating Behaviour And Its Relationship With Morphological Features In The Millipede Pachyiulus Hungaricus (Karsch, 1881) (Myriapoda, Diplopoda, Julida), Zvezdana Jovanovic, Sofija Pavkovic-Lucic, Bojan Ilic, Vukica Vujic, Boris Dudic, Slobodan Makarov, Luka Lucic, Vladimir Tomic

Turkish Journal of Zoology

Although millipedes (Diplopoda) represent one of the most diverse classes of arthropods, data concerning details of their mating behaviour are very scarce. In this work, we explored mating behaviour of the European millipede Pachyiulus hungaricus under laboratory conditions, and its relationship with the size and shape of certain morphological traits. We conducted 3 types of behavioural tests: a mating arena test, a female choice test, and a male choice test. Premating behaviour was "sequenced" in 5 behavioural steps and, together with the duration of copulation, scored in all mating assays. Males were the more active sex in searching for mates, …

A Case Of Limb Regeneration In A Wild Adult Podarcis Lilfordi Lizard, Alex Cortada, Antigoni Kaliontzopoulou, Joana Mendes, Miguel A. Carretero Jan 2017

A Case Of Limb Regeneration In A Wild Adult Podarcis Lilfordi Lizard, Alex Cortada, Antigoni Kaliontzopoulou, Joana Mendes, Miguel A. Carretero

Turkish Journal of Zoology

We report here a case of spontaneous limb regeneration in a wild Podarcis lilfordi lizard from the Balearic Islands. The animal had lost a hind limb, which regenerated posteriorly into a tail-like appendage. Despite not representing a functional regeneration, the growth of this structure after limb amputation suggests that survival of the individual may have been favored by the less restrictive conditions prevailing in insular environments. Nevertheless, such cases are extremely rare in lizards, with no reported cases over the last 60 years.

Prolonged Association Between A Pair And A Related Male In Breeding Whooper Swans (Cygnus Cygnus), Krzysztof Dudzik, Michal Polakowski, Michal Ciach Jan 2017

Prolonged Association Between A Pair And A Related Male In Breeding Whooper Swans (Cygnus Cygnus), Krzysztof Dudzik, Michal Polakowski, Michal Ciach

Turkish Journal of Zoology

Waterfowl (Anatidae) are a group of birds in which parental care is performed by both parents (a pair) or, less often, by females only. Alternative social systems in this group have been recorded only occasionally. This paper describes three unusual cases of prolonged association between a pair and an additional male (the offspring or sibling of the primary pair) in breeding Whooper Swans (Cygnus cygnus). In all instances the three birds displayed no antagonistic behaviour towards family members, participated in territorial defence, and bred successfully. These cases are unusual in light of what is currently known about the social system …

Bobcat Population Ecology In West Virginia, Stephanie Michelle Landry Jan 2017

Bobcat Population Ecology In West Virginia, Stephanie Michelle Landry

Graduate Theses, Dissertations, and Problem Reports (ETD)

Bobcats (Lynx rufus) are a popular furbearer and game species throughout their range in North America, where they serve as a top predator in many of their ecosystems. However, bobcat populations across their range declined during the 1800s and early 1900s due to overharvest. Overharvest and habitat loss in Europe also affected the Iberian lynx ( L. pardinus), resulting in the listing of all Lynx spp. under the Convention on International Trade in Endangered Species in 1977. Bobcats were listed under Appendix II, which required that state management agencies monitor their bobcat populations for stability. Since their listing, bobcat populations …

Microbial Quality And Pathogen Decontamination Strategies For Locally-Grown, Fresh Produce From West Virginia And Kentucky, Ka Wang Li

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study aimed to evaluate the microbiological quality/safety of fresh produce from farmers' markets (FM) and assess the post-harvest washing practice with antimicrobials to inactivate Salmonella and Listeria monocytogenes on fresh produce. In study I, 212 produce samples were tested for the presence of Salmonella and Listeria spp. using modified FDA-BAM methods. Aerobic plate counts (APCs), total coliforms (TCCs), and yeast/molds were analyzed on petri-films. Among the 212 samples, the APCs, TCCs, and yeast/molds were 3.72-5.63, 3.67-5.47, and 3.07-4.13 log CFU/g, respectively, with spinach containing the highest (P<0.05) populations. Among all tested samples, Salmonella enterica spp. enterica was detected on 18.6% of spinach, 10.9% of tomatoes, 18.5% of peppers, and 56.3% of cantaloupes, which is much higher than previous reported. Only 3.78% of the samples were confirmed for Listeria spp., and 50% of them were identified as L. monocytogenes, based on multiplex PCR results. Due to the high percentage of pathogens detected on the farmers' marker produce, an evaluation of post-harvest produce washing with various antimicrobials was conducted in study II. Specifically, spinach, tomatoes, green peppers and cucumbers were inoculated with S. Typhimurium and Tennessee or L. monocytogenes and washed in tap water, vinegar water (10%), lactic acid (5%), a lactic and citric acid blend (2.5%), and sodium hypochlorite (200 ppm) for 30 sec or unwashed. Vinegar water (10%) showed better (P<0.05) reduction of S. Typhimurium and Tennessee on tomatoes and cucumbers, and L. monocytogenes on tomatoes and peppers than tap water. The three antimicrobials reached an additional reduction level of 0.9 to 2.7 (S. Typhimurium and Tennessee) and 0.2 to 1.4 log CFU/g ( L. monocytogenes) compared to tap water. Lactic acid caused the greatest (P<0.05) reduction of S. Typhimurium and Tennessee on spinach and green peppers, and sodium hypochlorite showed the great (P<0.05) reduction of L. monocytogenes on cucumbers. The results supplied important information for FM vendors to develop post-harvest protocols to control foodborne pathogens.

The Use Of Concentration Of Anti-Mullerian Hormone (Amh) As An Indicator Of Reproductive Performance In Livestock Species, Adam Karl Russell Redhead Jan 2017

The Use Of Concentration Of Anti-Mullerian Hormone (Amh) As An Indicator Of Reproductive Performance In Livestock Species, Adam Karl Russell Redhead

Graduate Theses, Dissertations, and Problem Reports (ETD)

Reproductive success is essential for high levels of animal productivity. Low fertility has been identified as one of the main constraints hindering the productivity of livestock systems. To address this problem, several tools such as genomic selection and assisted reproductive techniques (ART) have been implemented. Two of the more common ART used to improve reproductive performance are artificial insemination (AI) and embryo transfer (ET). The success of these methods is highly dependent on individual animal characteristics; therefore the ability to select animals that provide high levels of reproductive success is essential. The size of the ovarian antral follicular population (AFP) …
