Trade‐offs across life history stages and social association types shape winter communal roosting in a long‐lived raptor

Journal of Animal Ecology, EarlyView.
Our study demonstrates how life history trade‐offs and pair bonds influence winter roosting in red kites. Analysing long‐term GPS data from 216 individuals, we reveal marked behavioural plasticity in communal roosting: young, non‐breeding males are most likely to join communal roosts, whereas breeding pairs predominantly roost together near their ...

Half a century of echinoid population decline in the northern Gulf of Aqaba, Red Sea

Journal of Animal Ecology, EarlyView.
Multi‐decadal monitoring in the Gulf of Aqaba, northern Red Sea, reveals severe (>90%) declines of key echinoid grazers. These declines signify a collapse of crucial herbivory functions underpinning coral reef resilience. Results implicate accelerating anthropogenic stress as a principal driver, emphasizing the urgent need for sustained, species ...

Delaying Screening Until Covered? Changes in Lung Cancer Screening at the Age of Nearly‐Universal Medicare Insurance

Health Services Research, EarlyView.
ABSTRACT Objective To estimate changes in lung cancer screening at age 65, the age of nearly universal Medicare coverage. Study Setting and Design Screening reduces lung cancer mortality but is underutilized. We used a regression discontinuity design to measure the impact of nearly universal Medicare coverage at age 65 on first‐time receipt of ...

Vog: Using Volcanic Eruptions to Estimate the Health Costs of Particulates

The Economic Journal, EarlyView., 2018
The negative consequences of long‐term exposure to particulate pollution are well established but a number of studies find no effect of short‐term exposure on health outcomes. The high correlation of industrial pollutants complicates the estimation of the impact of individual pollutants on health.

Reducing data processing effort in camera trap density estimation: Extending the REST model by explicitly modelling animal detection processes

Methods in Ecology and Evolution, EarlyView.
Abstract Accurate and reliable estimation of wildlife population density is fundamental to effective conservation and management. While camera traps show potential for monitoring ground‐dwelling mammal densities, labour‐intensive data processing remains a significant constraint. Ideally, conservation efforts would benefit from the continuous monitoring

OccuGAMs: Non‐linear occupancy and abundance modelling with imperfect detection

Methods in Ecology and Evolution, EarlyView.
Abstract Hierarchical occupancy and abundance models (HOAMs) have become a leading approach for inferring wildlife population dynamics because they explicitly account for imperfect detection. HOAMs are suitable for sampling approaches that produce detection histories from repeated visits to the same sites, including direct observations (e.g. bird point

Efficient multiplication for finite fields of p characteristic

Tongxin xuebao, 2009
Based on residue arithmetic,a new form of polynomial named PAPB in Fp[x] had been constructed.The amount and distribution of such irreducible polynomials had also been investigated.Then,an efficient algorithm for multiplication modulo PAPB had been ...

A Class of Binomial Permutation Polynomials

, 2013
In this note, a criterion for a class of binomials to be permutation polynomials is proposed. As a consequence, many classes of binomial permutation polynomials and monomial complete permutation polynomials are obtained. The exponents in these monomials are of Niho type.

Global field trials show the advantages of beta regression compared with logit transformation and quasi‐likelihood for the analysis of percentage plant disease severity

Annals of Applied Biology, EarlyView.
Disease severity in crop protection field trials is commonly assessed as a proportion represented as a percentage. Traditional statistical analysis uses transformation to logit or angle. This study compares analyses based on the beta distribution and the quasi‐likelihood method with the logit transform using a large global data set of field trials ...
