Fluctuations in rodent population densities in North America are a reality. Our understanding of the factors causing such fluctuations is incomplete; therefore, it is important to monitor populations to increase our understanding of natural wildlife communities so as to avoid substantial damage to agriculture, forestry, and urban infrastructures, and to prevent rodent-borne disease transmission...

Cotton rats, roof rats, and rice rats collectively inflict significant damage to sugarcane crops in the Everglades Agricultural Area; however, the relative damage inflicted by each species is unknown. A feeding trial experiment showed that some differences existed in the grams of sugarcane consumed per gram of body mass among species (male cotton rats: 0.39 ± 0.03g; female cotton rats: 0.34 ± 0...

Using domestic predators such as cats to control rodent pest problems around farms and homesteads is common across the world. However, practical scientific evidence on the impact of such biological control in agricultural settings is often lacking. We tested whether the presence of domestic cats and/or dogs in rural homesteads would affect the foraging behaviour of pest rodents. We estimated gi...

Given that rodents are responsible for nearly 280 million cases of undernutrition worldwide and about 400 people affected by rodent-associated zoonoses annually, management rodent populations agricultural pests and/or reservoirs pathogens is a major food security public health matter. In sub-Saharan Africa, the median crop loss due to 16% in field around 8% during storage. The impact on not wel...

IMPORTANCE Cable grafting is widely considered to be the preferred alternative to primary repair of the injured facial nerve; however, quantitative comparison of the 2 techniques has not been previously undertaken in a rodent model. OBJECTIVE To establish functional recovery parameters after interposition autografting in a rodent facial nerve model. DESIGN, SETTING, AND PARTICIPANTS Prospec...

BACKGROUND & OBJECTIVES ZCL is a growing threat in many rural areas of Iran which involves 17 out of 31 provinces. This study was conducted from April to November 2011 for evaluation of the efficacy of phostoxin and zinc phosphide against rodents. METHODS Rodent control operations were carried out using phostoxin and zinc phosphide. To evaluate the effect of rodent control operation on the ma...

Nocturnal synthesis of melatonin in the pineal gland is controlled by a circadian rhythm in arylalkylamine N-acetyltransferase (AANAT) enzyme activity. In the rodent, Aanat gene expression displays a marked circadian rhythm; release of norepinephrine in the gland at night causes a cAMP-based induction of Aanat transcription. However, additional transcriptional control mechanisms exist. Homeobox...

On October 19-21, 2004, the USDA, APHIS, Wildlife Services, National Wildlife Research Center (NWRC) in Fort Collins, CO, hosted the 2nd National Invasive Rodent Summit. The conference was jointly sponsored by the NWRC, the U.S. Fish and Wildlife Service (FWS) and The Wildlife Society’s Wildlife Damage Management Working Group. The conference was a follow-up to the 2001 “Rat Summit” held in San...

Abstract Rodent population control is a global problem, complicated by evolved non-responsiveness to rodenticide treatment. Contraceptives could help mitigate this challenge, but questions remain about their efficacy, especially for rodenticide-resistant populations. We used an age-dependent demographic model generate two hypotheses: Fertility reduction applied early in female lifetimes (1) mor...

Oxygen is essential for life, and cells have therefore developed numerous adaptive responses to oxygen change. Here, we examined the difference in oxygen-control functions of human (HE), mouse (ME), and Syrian hamster embryo (SHE) cells cultured under different oxygen conditions (0.5%, 2% and 20%), and also examined whether oxygen tensions contributed to cellular lifespan and transformation. HE...
