Flexible and non-invasive passive integrated transponder (PIT) tagging protocols for tropical freshwater fish species

open access: yesMethodsX, 2018
Passive integrated transponder (PIT) tagging has proven to be an effective mark-recapture technique for many temperate freshwater and marine fish species, but its adaptability to tropical freshwater species remains largely unknown.

Trappability estimates for mark–recapture data [PDF]

open access: yesCanadian Journal of Zoology, 1984
Mark–recapture methods produce more accurate estimates when a high fraction of the population is trapped. Three estimates of trappability are used in the literature, and we compare them for four species of Microtus livetrapped in Longworth traps. The trappable population is defined by the weight at first capture and varies greatly in different species.

Sertraline Treatment Can Mimic Niemann‐Pick Type C Biomarker Profile: A Diagnostic Pitfall

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Oxysterols (cholestane‐3β,5α,6β‐triol and 7‐ketocholesterol) and N‐palmitoyl‐O‐phosphocholineserine (PPCS) are sensitive biomarkers for Niemann‐Pick disease type C (NPC) screening. However, false‐positive results occur, with a biomarker profile suggestive of NPC despite the absence of pathogenic variants in genes involved in NPC or ...

Long-term trends in the use of a protected area by small cetaceans in relation to changes in population status

open access: yesGlobal Ecology and Conservation, 2014
The requirement to monitor listed species in European designated sites is challenging for long-lived mobile species that only temporarily occupy protected areas.

Integrating acoustic telemetry into mark–recapture models to improve the precision of apparent survival and abundance estimates

open access: yesOecologia, 2015
Capture–mark–recapture models are useful tools for estimating demographic parameters but often result in low precision when recapture rates are low. Low recapture rates are typical in many study systems including fishing-based studies.

Multimode Oxide‐Based Optoelectronic Memtransistor for In‐Sensor Vision Processing

open access: yesAdvanced Functional Materials, EarlyView.
A multimode optoelectronic memtransistor (OEMT) is demonstrated for vision explainable artificial intelligence (VXAI) hardware. By integrating optical sensing, electrical masking, and non‐volatile memory, the device enables key operations required for generating saliency information.

Evaluation of population densities of the common wolf spider Pardosa agrestis (Araneae: Lycosidae) in Hungarian alfalfa fields using mark-recapture

open access: yesEuropean Journal of Entomology, 2000
The absolute population density of adult Pardosa agrestis (Westring, 1862), the dominant epigeic spider species in many arable lands in Central Europe, was quantified in two alfalfa fields using a multiple mark-recapture method.

Boolean Logic‐Based Control Over Recombinant Protein Biomaterial Degradability and Therapeutic Delivery

open access: yesAdvanced Materials, EarlyView.
Fully recombinant protein‐based biomaterials execute complex Boolean logic for user‐programmable material degradation and concomitant therapeutic cargo release. Biologics, such as growth factors, can be incorporated within the crosslinkers as “drugamers”, while encapsulated cells can be released according to nested YES/OR/AND‐type logical operations ...

Adult Sex Ratio as a Demographic Feedback Linking Mating Systems, Parental Care, and Evolution

open access: yesAdvanced Science, EarlyView.
Breeding systems are some of the most diverse social behavior, and our team is investigation the evolutionary causes of this diversity. This review summarises our research carried out at the University of Bath. We argue that demographic components of wild populations, especially the adult sex ratio, plays a key role driving breeding system variation ...
