Abstract:
... Amendment with sewage sludge or biosolids can increase soil fertility but may also transfer biosolid-borne pollutants to the soil and the possible effects on the soil ecosystem are poorly understood, especially long-term effects. A long-term experiment was therefore established to assess the effects of repeated applications of different types of biosolids (fresh domestic, dried domestic and fresh ...

Abstract:
... Schirmer tear test (STT), intraocular pressure (IOP), and ocular biometry were measured in 58 healthy cheetahs (Acinonyx jubatus) between the ages of 2 and 14 yr in two captive groups. During routine health examination under immobilization, each animal underwent ophthalmic examination including STT, IOP, slit-lamp biomicroscopy, indirect ophthalmoscopy, and ocular ultrasonography. Mean ± SD values ...

Abstract:
... Gut microbiota contribute to host health. Numerous recent studies have focused on the survival and reproduction of nontarget soil animals exposed to the toxicity of silver nanoparticles (AgNPs) but changes in the gut microbiota due to nanoparticle toxicity are largely unknown. Here, we examine some effects of AgNPs and silver nitrate (ionic Ag) on the gut microbiota of the common soil collembolan ...

Abstract:
... Peptides are the largest/most diverse class of molecules used by animals for chemical communication, and with their cognate receptors, are key players in modulating physiological/behavioral control systems, including those involved in adaptation to environmental change. Crustaceans have long served as models for investigating peptidergic control of physiology/behavior, and members of Notostraca, a ...

Abstract:
... Clean meat (meat grown in cell culture rather than obtained from animal slaughter) is an emerging biotechnology industry that will ameliorate the serious environmental, sustainability, global public health, and animal welfare concerns of industrial animal agriculture. While many technologies and products developed for the cell therapy industry can already be applied to clean meat, significant oppo ...

Abstract:
... Effects of microplastics on aquatic organisms have been widely studied in recent years but effects on soil biota, and especially on the gut microbiota of soil animals, remain poorly understood. An experiment was therefore conducted using the common soil collembolan Folsomia candida exposed to microplastics for 56 days to investigate the effects of plastics on gut microbiota, growth, reproduction a ...

Abstract:
... Highly precise and reliable determination of heavy metals in soil micro-arthropod tissues remains a challenge because of the small size of the animals and their typical low abundance in metal-contaminated agricultural soils. The present study sought to develop a method for cadmium (Cd) determination in soil micro-arthropods by optimizing the sample digestion procedure, reducing sample weight, modi ...

Abstract:
... An animal's microhabitat requirements can impact its ability to colonize restored areas, particularly species requiring slow developing microhabitats, such as logs and woody debris piles. Introduction of these microhabitats may be required to facilitate colonization by some species. Restored bauxite mine‐pits in the Jarrah (Eucalyptus marginata) forest of south‐western Australia contain introduced ...

Abstract:
... Foot-and-Mouth Disease Virus (FMDV) is a picornavirus that infects cloven-hoofed animals and leads to severe losses in livestock production. In the case of an FMD outbreak, emergency vaccination requires at least 7 days to trigger an effective immune response. There are currently no approved inhibitors for the treatment or prevention of FMDV infections. Using a luciferase-based assay we screened a ...

Abstract:
... Coastal eutrophication may alter the dominance patterns of marine macroalgae, with potential consequences for the associated fauna and the entire ecosystem. Benthic macroalgae and animals in control and nutrient-enriched mesocosms were monitored to investigate eutrophication-induced changes in rocky shore communities. During a 3-year project, nutrient addition had only minor effects on the communi ...
