An Integrative Description Of Macrobiotus Hannae Sp. Nov. (Tardigrada: Eutardigrada: Macrobiotidae: Hufelandi Group) From Poland, Bernadeta Nowak, Daniel Stec
Turkish Journal of Zoology
A new species of the Macrobiotus hufelandi group is described from Poland. An integrative taxonomic approach was applied by combining morphological and morphometric analysis imaging under phase contrast and scanning electron microscopy with molecular analysis (four molecular markers) to unambiguously support the establishment of the new species. The specimens of Macrobiotus hannae sp. nov. are similar to three taxa of the Macrobiotus hufelandi complex: Macrobiotus hufelandi C.A.S. Schultze, 1834; M. punctillus Pilato, Binda & Azzaro, 1990; and M. joannae Pilato & Binda, 1983. Nevertheless, the new species differs from the first two species by the absence of cuticular bars under …

Potential Distribution Of The Guava Psyllid Triozoida Limbata (Hemiptera, Psylloidea), Today And In Global Climate Change Scenarios, Dalva Queiroz, Marcos Silveira Wrege, Talita Benedcta Santos Künast, Marilice Cordeiro Garrastazu, Daniel Burckhardt
Turkish Journal of Zoology
The jumping plant-louse Triozoida limbata is monophagous on guava (Psidium guajava), inducing leaf galls. Guava is planted today in warmer regions around the world but T. limbata is restricted to Central and South America. Recently, the latter has become a key pest in commercial plantations in Brazil (Pernambuco and São Paulo). Modeling of potential distributions is a good tool for developing control strategies of insect pests. Based on distributional data from the Americas, we created models for the psyllids for the present and future using different scenarios of climate change. The OpenModeller eco-niche modeling program was used with the Environmental …

Insect-Specific Peptides In The Venom Of Wolf Spiders (Araneae: Lycosidae), Hafiz Muhammad Tahir, Khanum Zahra, Azhar Abbas Khan
Insect-Specific Peptides In The Venom Of Wolf Spiders (Araneae: Lycosidae), Hafiz Muhammad Tahir, Khanum Zahra, Azhar Abbas Khan
Turkish Journal of Zoology
The venom of two dominant species of wolf spiders, Pardosa sumatrana Thorell and Pardosa birmanica Simon, was extracted and characterized. Insecticidal potential of crude venom and selected peptide fractions (i.e. 35-kDa fraction of both spiders) was evaluated in the laboratory using Rhopalosiphum padi (Linnaeus) (Homoptera: Aphididae) as a model pest. Results of the study showed that both the crude venom and the protein fractions caused significantly higher mortality in treated aphids compared to the control. It is concluded that both the crude venom and the protein fractions possess insecticidal potential.

Competing Activities As Measures Of Fear And Vigilance, Ferenc Mónus
Competing Activities As Measures Of Fear And Vigilance, Ferenc Mónus
Animal Sentience
In animal behavioural research on vigilance, visual signs of alertness are usually used to estimate perceived risk (an internal “fear” state) of free-ranging animals. Different measures of vigilance and competing activities (e.g., predator vigilance, conspecific vigilance, feeding, food handling) provide clues for better understanding vigilance behaviour. How efficiently does an animal in a vigilant/non-vigilant posture devote attention to threats or invest in other activities, such as searching for or handling food? Several species regularly withdraw to a sheltered spot when feeding in an abundant food patch, spending short periods in complete safety. Frequencies of feeding interruptions or false-alarm flights provide …

Compression And Relaxation Of Fishing Effort In Response To Changes In Length Of Fishing Season For Red Snapper (Lutjanus Campechanus) In The Northern Gulf Of Mexico, Sean P. Powers, Kevin Anson
University Faculty and Staff Publications
A standard method used by fisheries managers to decrease catch and effort is to shorten the length of a fishery; however, data on recreational angler response to this simple approach are surprisingly lacking. We assessed the effect of variable season length on daily fishing effort, measured by using numbers of boat launches per day, anglers per boat, and anglers per day from video observations, in the recreational sector of the federal fishery for red snapper (Lutjanus campechanus) in coastal Alabama. From 2012 through 2017, season length fluctuated from 3 to 40 d. Daily effort, measured by using mean number of …

Distance Models As A Tool For Modelling Detection Probability And Density Of Native Bumblebees, Darin J. Mcneil, Clint R. V. Otto, Erin L. Moser, Katherine R. Urban‐Mead, David E. King, Amanda D. Rodewald, Jeffery L. Larkin
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
Effective monitoring of native bee populations requires accurate estimates of population size and relative abundance among habitats. Current bee survey methods, such as netting or pan trapping, may be adequate for a variety of study objectives but are limited by a failure to account for imperfect detection. Biases due to imperfect detection could result in inaccurate abundance estimates or erroneous insights about the response of bees to different environments. To gauge the potential biases of currently employed survey methods, we compared abundance estimates of bumblebees (Bombus spp.) derived from hierarchical distance sampling models (HDS) to bumblebee counts collected from fixed‐area …

An Historical Overview And Update Of Wolf-Moose Interactions In Northeastern Minnesota, L. David Mech, John Fieberg, Shannon M. Barber-Meyer
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
Wolf (Canis lupus) and moose (Alces americanus) populations in northeastern Minnesota, USA, have fluctuated for decades and, based on helicopter counts, moose numbers declined to a new low from 2006 to about 2012. Other steep declines were found in 1991 and 1998 during periods when moose counts were done with fixed-wing aircraft; these declines also appeared to be real. Winter wolf numbers, monitored in part of the moose range, had been increasing since about 2002 to the highest population in decades in 2009. However, from 2009 to 2016, wolves decreased precipitously, and the moose- population decline leveled …

University of Nebraska State Museum: Mammalogy Papers
Conclusions
It is our contention that Thomas Say, Titian Peale, Edwin James, and their colleagues of the Stephen Long Expedition of 1819–1820 were heavily engaged in scientific research, which took the form of the first biodiversity inventory undertaken in the United States. This accomplishment has been overlooked both by biologists and historians, but it should rank among the most significant accomplishments of the expedition. The results of this inventory continue to inform us today about environmental, faunal, and floral changes along the Missouri River in an area that is known to be an ecotone between the deciduous forests of the …

Towards Understanding The Role Of Small Mammals In The Transmission Of Lyme Disease In Virginia, Usa, Robert K. Rose, Laura Bitzer, Wayne Hynes, Holly D. Gaff, Robyn Nadolny, Jory Brinkerhoff
Biological Sciences Faculty Publications
Larvae and nymphs of many species of ticks select small mammals, reptiles, and birds as hosts. Since 2011, we have examined more than 1,000 small mammals of 10 species and collected a small tissue sample as well as all visible ticks; rates of infestation range from 18% in harvest mice to 53% in meadow voles. Identification of immature ticks is challenging and requires molecular or genetic methods beyond classification as being from the genus Ixodes or another genus. Ixodes ticks include Ixodes scapularis, the species that transmits the Lyme disease-causing bacterium Borrelia burgdorferi to humans. Of the approximately 2,300 ticks …
Adiposity And Fat Metabolism During Combined Fasting And Lactation In Elephant Seals, Melinda Fowler, Cory Champagne, Daniel Croker
Adiposity And Fat Metabolism During Combined Fasting And Lactation In Elephant Seals, Melinda Fowler, Cory Champagne, Daniel Croker
Biological Sciences Faculty Publications
Animals that fast depend on mobilizing lipid stores to power metabolism. Northern elephant seals (Mirounga angustirostris) incorporate extended fasting into several life-history stages: development, molting, breeding and lactation. The physiological processes enabling fasting and lactation are important in the context of the ecology and life history of elephant seals. The rare combination of fasting and lactation depends on the efficient mobilization of lipid from adipose stores and its direction into milk production. The mother elephant seal must ration her finite body stores to power maintenance metabolism, as well as to produce large quantities of lipid and protein rich …
Do Avian Blood Parasites Influence Hypoxia Physiology In A High Elevation Environment?, Farah Ishtiaq, Sahas Barve
Do Avian Blood Parasites Influence Hypoxia Physiology In A High Elevation Environment?, Farah Ishtiaq, Sahas Barve
Biological Sciences Faculty Publications
BACKGROUND: Montane birds which engage in elevational movements have evolved to cope with fluctuations in environmental hypoxia, through changes in physiological parameters associated with blood oxygen-carrying capacity such as haemoglobin concentration (Hb) and haematocrit (Hct). In particular, elevational migrants which winter at low elevations, encounter varying intensities of avian haemosporidian parasites as they traverse heterogeneous environments. Whilst high intensity parasite infections lead to anaemia, one can expect that the ability to cope with haemosporidian infections should be a key trait for elevational migrants that must be balanced against reducing the oxygen-carrying capacity of blood in response to high elevation. In …
Review: Application Of Tick Control Technologies For Blacklegged, Lone Star, And American Dog Ticks, Alexis White, Holly Gaff
Review: Application Of Tick Control Technologies For Blacklegged, Lone Star, And American Dog Ticks, Alexis White, Holly Gaff
Biological Sciences Faculty Publications
Tick population control technologies have been studied for several decades but no method is successful in all situations. The success of each technology depends on tick species identity and abundance, host species identity and abundance, phenology of both ticks and hosts, geographic region, and a multitude of other factors. Here we review current technologies, presenting an overview of each and its effect on three common tick species in the eastern United States: blacklegged ticks (Ixodes scapularis (Say; Ixodida: Ixodidae)), lone star ticks (Amblyomma americanum (Linnaeus; Ixodida: Ixodidae)), and American dog ticks (Dermacentor variabilis (Say; Ixodida: Ixodidae)). Moreover, …

(First paragraph) Chollett et al. (2017) make the case that a local network of marine protected areas (MPAs) enhances fisheries for Caribbean spiny lobster (Panulirus argus) off the coast of Honduras.

The shallow banks and scattered cays of the Honduran-Nicaraguan Rise, separating the Cayman and Colombian basins, create an obstacle to the powerful southern Caribbean jet (Richardson, 2005), fostering an ideal location for topographically steered eddies and larval retention. Local management,whether based on traditional …
