The role of backcountry huts as focal points for weed establishment and spread into New Zealand’s national parks has received little attention. In this study we describe the pattern of weed spread around Takahe Valley Hut, Murchison Mountains, Fiordland National Park. Established in 1948, the hut is located at 900 m a.s.l. at the ecotone between Nothofagus forest and valley floor shrubland/gras...

SPECIAL NEEDS FOR THE EXOTIC SMALL MAMMAL PATIENT In general, basic equipment used for dogs and cats can be used on many rabbits, rodents, and ferrets. Most exotic small mammals tend to be very little; therefore, pediatric equipment is a must. For example, the heart rate of many exotic small mammals can easily be over 350 beats per minute. In many species, this would be considered tachycardic, ...

Methods: We monitored plant community composition in paired grassland patches that were initially dominated by native or exotic grasses at eight sites. We followed recovery of native and exotic grassland species over time, starting in a record drought year prior to an intense fire, and then for 3 yrwithmore typical rainfall patterns after the fire. Additionally, we compared seed rain of native ...

Research The U.S. Clean Air Act designates hazardous air pollutants (HAPs) as those that " may reasonably be anticipated to be carcinogenic, mutagenic " (Clean Air Act Amendments 1990), and exhibit other adverse health effects. Effective reduction of exposures to HAPs requires determining the compounds, exposure pathways, and sources that contribute the most to human health risk. Many prior ris...

In this paper I review a number of recent results in the field of exotic atoms. Recent experiments or ongoing experiments with muonic, pionic and antiprotonic hydrogen, as well as recent measurement of the pion mass are described. These experiments provide information about nucleon-pion or nucleonantinucleon interaction as well as information on the proton structure (charge or magnetic moment d...

A particle system with a (2+1)D exotic Newton-Hooke symmetry is constructed by the method of nonlinear realization. It has three essentially different phases depending on the values of the two central charges. The subcritical and supercritical phases (describing 2D isotropic ordinary and exotic oscillators) are separated by the critical phase (one-mode oscillator), and are related by a duality ...

BACKGROUND In view of recurrent Schmallenberg virus (SBV) infections all over Europe between 2011 and 2013, a lively scientific debate over the importance of the sylvatic transmission cycle of the virus has emerged. The study presents results of serosurvey which included wild ruminants representing species of red deer (Cervus elaphus), roe deer (Capreolus capreolus), European bison (Bison bonas...

Thekaryotype, C-banding, and nucleoar organizer regions (NORs) of eight specimens ofKonya wild sheepfrom Turkey were examined. The complement included six large metacentric autosomes, 46 acrocentric autosomes of decreasing size, a medium-sized acrocentric X chromosome, and a small bi-armed Y chromosome (the diploid chromosome number 2n=54, the number of autosomal arms NFa=58, the number of chro...

OBJECTIVES The aim was to identify conjunctival bacterial and fungal flora in clinically normal sheep. DESIGN Prospective study. SETTING Tuscany. PARTICIPANTS 100 eyes from 50 adult Massese female sheep were examined. The sheep included in the study were considered free of anterior ophthalmic abnormalities. PRIMARY AND SECONDARY OUTCOME MEASURES Bacteria were identified by morphological...
