Performance of a Deep Learning Algorithm for Melanoma Classification Across Diverse Dermoscopic and Tele‐Dermatology Datasets

JEADV Clinical Practice, EarlyView.
ABSTRACT Background Early detection of melanoma significantly boosts patient survival rates. Deep learning has demonstrated dermatologist‐level accuracy in assessing pigmented skin lesions by analysing images at the pixel level. However, these neural networks may face challenges with ‘real‐life’ images due to limited training data and image artefacts ...

Changes in capture availability due to infection can lead to detectable biases in population-level infectious disease parameters [PDF]

PeerJ
Correctly identifying the strength of selection that parasites impose on hosts is key to predicting epidemiological and evolutionary outcomes of host-parasite interactions. However, behavioral changes due to infection can alter the capture probability of

Nutritional and reproductive dynamics of moose near their southern range limit

The Journal of Wildlife Management, EarlyView.
Though southern moose (Alces alces) had relatively low seasonal fluctuations in body fat, their condition was positively associated with pregnancy and adult survival but did not influence recruitment of young. We demonstrated clear signs of nutritional limitation and unexpected patterns of reproductive performance that may be unique to moose living at ...

Spatial and temporal variation in survival of female wild turkeys

The Journal of Wildlife Management, EarlyView.
We monitored 370 female wild turkeys across North Carolina's 3 ecoregions from 2020‐2022 to understand factors influencing their survival. Female survival varied by ecoregion and behavior state, with the incubation period having the lowest survival rates. None of the land cover variables affected survival.

Individual movement modeling expands the power of migratory species observations: North Atlantic right whale case study

Limnology and Oceanography: Methods, EarlyView.
Abstract Understanding a population's distribution depends on observing the presence and movement of individuals throughout their range. For highly mobile marine species, these observations typically rely on high effort monitoring programs. Tracking enough individuals to understand trends in movement behavior is not always logistically feasible, and ...

The Effect of Age on Survival Is Similar in Males and Females of an Aquatic Insect Species

Ecologies
Age is a critical intrinsic factor that influences the probability of survival of organisms on Earth. In many animals, the lifestyles and habitat occupancy of males and females are so different that the effect of age could be sex-dependent.

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

Global 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.

Population size estimates based on the frequency of genetically assigned parent–offspring pairs within a subsample

Ecology and Evolution, 2020
Estimating population density as precise as possible is a key premise for managing wild animal species. This can be a challenging task if the species in question is elusive or, due to high quantities, hard to count.

Tactical and Strategic Risks From Supply Disruptions in Competing Supply Chains

Naval Research Logistics (NRL), EarlyView.
ABSTRACT Supply chain disruptions can lead to both tactical (i.e., loss of short‐term sales during a disruption) and strategic (i.e., loss of long‐term market share) consequences. We model the impact of a supply disruption on competing supply chains in which two firms compete for a limited backup supply.

Stratified sampling enhances the understanding of bat–fruit networks in the southern Atlantic Forest

Oikos, EarlyView.
Few studies have sought to understand the vertical patterns of bat–fruit systems, and therefore, it is not possible to evaluate whether interpretations based on data collected from a single stratum adequately represent the interaction patterns of this system. In this context, we evaluated the dissimilarity in the assemblage of frugivorous bats, plants,
