Success of animal translocations depends on improving post-release demographic rates toward establishment and subsequent growth of released populations. Short-term metrics for evaluating translocation success and its drivers, like post-release survival and fecundity, are unlikely to represent longer-term outcomes. We used information theory to investigate 25 years of black rhinoceros (Diceros bicornis) translocations using the offspring recruitment rate (ORR) of translocated females - a metric integrating survival, fecundity and offspring recruitment at sexual maturity - to detect determinants of success...

Freshwater ecosystems provide many ecosystem services; however, they are often degraded as a result of human activity. To address ecosystem degradation in the Laurentian Great Lakes, Canada and the United States of America established the Great Lakes Water Quality Agreement (GLWQA). In 1987, 43 highly polluted and impacted areas were identified under the GLWQA as having one or more of 14 Beneficial Use Impairments (BUIs) to the physical and chemical habitat for fish, wildlife and humans, and were designated as Areas of Concern (AOC)...

Echinococcus granulosus is the causative agent of cystic echinococcosis (CE), which is distributed all around the world. CE is one of the most important global parasitic infectious diseases, both in humans and animals. This parasite causes hydatid cysts that can be lodge at different organs of host such as liver, lung even in heart and brain which may lead to death. Presently, numerous scolicidal chemical agents have been administrated for inactivation of the hydatid cyst contents. Because of increasing resistance and adverse effects of medications include abnormalities of liver function, abdominal pain, diarrhea, nausea, vomiting, dizziness, and headache; there is a need to find alternative therapies either with the least or without side effects...

A brief history of bovine tuberculosis (bTB) and its control in Great Britain (GB) is presented. Numerous diverse policies to control the disease in humans, cattle and wildlife have been pursued over the last 100 years and many millions of pounds have been spent. After notable success in reducing the incidence and prevalence of bTB in cattle in GB from the 1950s to the mid-1980s, the geographical spread of the disease and the number of cattle slaughtered have increased continually since that time, with a high point of bTB incidence in 2008...

The growing complexity of biobanking requires dedicated professional staff who are trained in multiple aspects of the biobanking process, including technical, managerial, regulatory, and ethical aspects, and who have a good understanding of the challenges of biospecimen research, but also of the challenges related to the sustainability of future biobanks. Up to the present, biobanking staff have been trained in an ad-hoc manner, usually through specific short duration courses, for example, summer schools. In this article, we describe the development/establishment of a systematic 2-year training program at the Master level intended for students with a background in life sciences and providing them with a professional qualification as a "Biobank Manager...

We show how faceted search using a combination of traditional classification systems and mixed-membership topic models can go beyond keyword search to inform resource discovery, hypothesis formulation, and argument extraction for interdisciplinary research. Our test domain is the history and philosophy of scientific work on animal mind and cognition. The methods can be generalized to other research areas and ultimately support a system for semi-automatic identification of argument structures. We provide a case study for the application of the methods to the problem of identifying and extracting arguments about anthropomorphism during a critical period in the development of comparative psychology...

The genomic revolution has fundamentally changed how we survey biodiversity on earth. High-throughput sequencing ('HTS') platforms now enable the rapid sequencing of DNA from diverse kinds of environmental samples (termed 'environmental DNA' or 'eDNA'). Coupling HTS with our ability to associate sequences from eDNA with a taxonomic name is called 'eDNA metabarcoding' and offers a powerful molecular tool capable of non-invasively surveying species richness from many ecosystems. Here, we review the use of eDNA metabarcoding for surveying animal and plant richness, and the challenges in using eDNA approaches to estimate relative abundance...

The bright bioluminescence catalysed by Photinus pyralis firefly luciferase (Fluc) enables a vast array of life science research such as bioimaging in live animals and sensitive in vitro diagnostics. The effectiveness of such applications is improved using engineered enzymes that to date have been constructed using amino acid substitutions. We describe ΔFlucs: consecutive single amino acid deletion mutants within 6 loop structures of the bright and thermostable x11 Fluc. Deletion mutations are a promising avenue to explore new sequence and functional space and isolate novel mutant phenotypes...

Symmetry is one of the essential and most visible patterns that can be seen in nature. Starting from the left-right symmetry of the human body, all types of symmetry can be found in crystals, plants, animals and nature as a whole. Similarly, principals of symmetry are also some of the fundamental and most useful tools in modern mathematical natural science that play a major role in theory and applications. As a consequence, it is not surprising that the desire to understand the origin of life, based on the genetic code, forces us to involve symmetry as a mathematical concept...
