Summary: Remotely-sensed data can enhance conservation efforts for forest wildlife by providing information on fine-scale structural variation. LiDAR datasets covering large spatial extents and ownership types can improve our understanding of species-habitat relationships and aid in habitat recovery programs. The fusion of LiDAR data with field surveys has proven effective in predicting forest bird habitat associations and can be a valuable tool for conservation planning.

Summary: The article introduces a novel hierarchical nonparametric process for defining priors on collections of probability distributions to model hazard rates and induce dependence through mixing random measures. The theoretical results allow for the development of a comprehensive Bayesian analysis for this class of models, which can also consider right-censored survival data and covariates.

Summary: In this 34-year study of acorn woodpeckers, the population increased considerably despite a reduction in high-quality breeding habitat. The increase in abundance was largely determined by the formation of new social groups, driven by the expansion of canopy cover and neighborhood-level acorn abundance. These findings suggest that scale-dependent processes and resource availability play important roles in driving changes in population dynamics.

Summary: This study in the Swiss Alps area aimed to characterize spatio-temporal patterns of food availability for the Ring Ouzel by sampling earthworms over a breeding season. The study found that ground vegetation cover and soil moisture were suitable predictors for the number of earthworms in the soil profile at each sampling time. It also provided evidence of a seasonal peak in earthworm availability, with differences between open grasslands and forested areas depending on snowmelt stages.

Summary: A design-based strategy is proposed to estimate the abundance of deer populations and analyze habitat selection using pellet group counts. This strategy is free of model assumptions and relies on probabilistic sampling and stratified sampling for statistical soundness.

Summary: This paper considers a new generalized finite mixture model and establishes comparisons for the lifetimes of two such models under different scenarios. The established results are used to compare the lifetimes of k-out-of-n systems and coherent systems in terms of reversed hazard rate and hazard rate orderings.

Summary: This paper discusses variable selection for interval-censored failure time data with a cured fraction using a penalized likelihood function. The proposed method employs a sieve approach and a penalized EM algorithm, with asymptotic properties of the estimators obtained. Simulation studies and real data application demonstrate the good performance of the method in practice.

Summary: GREED is an objective VQA model that analyzes the statistics of spatial and temporal band-pass video coefficients to evaluate video quality. By using entropic differences and a learned regressor, GREED achieves state-of-the-art performance on high frame rate video databases.

Summary: This study analyzed the dynamic mechanical properties and damage prediction of 3003 aluminum alloy for its safe application on lightweight automobiles. It was found that the alloy showed significant strain rate sensitivity in yield strength and fracture prolongation. By modifying the Johnson-Cook constitutive equation using the GISSMO model, the damage behavior of the alloy was accurately predicted. The reliability of the modified model was confirmed through cupping experiments and simulations.

Summary: This paper is the first of two articles focusing on dissipative generalized Drude-Lorentz open structures. We aim to quantify the loss in such media by using an approach based on frequency-dependent Lyapunov estimates, which reduces the long-time decay rate of electromagnetic energy.

Summary: This article presents a novel stochastic removal mechanism using Generalized Linear Models (GLM) with dependent removal probabilities based on lifetime conditions. It investigates the parameter estimation and variance estimation for the Weibull distributed removal mechanism under Type-II progressive random censoring. A simulation algorithm for generating samples with GLM-based removal probabilities is also provided, and the expected experiment time is analyzed using Monte Carlo integration method. The performance of the proposed mechanism is evaluated through simulation studies and real data analysis, and the sensitivity analysis is considered.

Summary: A study compared breeding parameters of female Eurasian reed warblers in two periods, 1980-1983 and 2005-2012, and found that the breeding season has extended by 2 weeks in recent years, with a 75% increase in fledglings produced annually by females. The study suggests that the longer breeding season and increased re-nesting opportunities in response to climate change have led to higher offspring production and may benefit some species. Further research is needed to understand the causes and consequences of changes in the duration of breeding seasons for predicting population dynamics under changing climatic conditions.

Summary: In Whiskered Tern chicks, males are generally larger and have a higher maximum growth rate than females, indicating that raising sons may be more costly than raising daughters. Nestling growth is also significantly affected by brood size and hatching date, with larger and later clutches generally showing lower growth rates.

Summary: This study characterized the nest sites of the European robin in the natural conditions of a primeval forest. The results showed that the majority of nests were found in tree holes, and the robins exhibited a weak preference for certain tree species. The availability of nest sites appeared to influence the selection of ground nests.

Summary: This study investigated the body condition of Whiskered Terns and found that half of the females desert during the chick-rearing period. The body condition of the females that deserted was significantly poorer than the females that stayed. The body condition of males was also affected by the desertion of females.

Summary: This study provides the earliest estimation of the white stork population size and spatial distribution in Poland, revealing a significant decline in the population between 1958 and 1974. The findings demonstrate strong spatial variations in population changes across the country, with the most abundant populations in Eastern Poland experiencing the largest declines. These results highlight the importance of solid data in understanding long-term population dynamics.
