Transition probabilities for general birth-death processes with applications in ecology, genetics, and evolution [PDF]
A birth-death process is a continuous-time Markov chain that counts the number of particles in a system over time. In the general process with $n$ current particles, a new particle is born with instantaneous rate $\lambda_n$ and a particle dies with instantaneous rate $\mu_n$.

'DIS_turbation': An Artistic Approach to Foster Nature-Connectedness [PDF]
This paper presents practice-based research on ecoacoustics, ocean soundscapes and anthropogenic noise. It explores creative strategies to the introduction, experience and performance of ocean soundscapes in artistic creation.

Modeling of small sea floaters in the central Mediterranean Sea: seasonality of at-sea distributions [PDF]
Floating marine debris represent a threat to marine and coastal ecology. Since the Mediterranean basin is one of the highly impacted regions, both by the coastal pollution as well as from sea traffic, the potential harm of a floating pollution on the marine ecology could be overwhelming in this area.

Interplay between particle size and microbial ecology in the gut microbiome [PDF]
Abstract Physical particles can serve as critical abiotic factors that structure the ecology of microbial communities. For non-human vertebrate gut microbiomes, fecal particle size (FPS) has been known to be shaped by chewing efficiency and diet. However, little is known about what drives FPS in the human gut.

Ecological non-linear state space model selection via adaptive particle Markov chain Monte Carlo (AdPMCMC) [PDF]
We develop a novel advanced Particle Markov chain Monte Carlo algorithm that is capable of sampling from the posterior distribution of non-linear state space models for both the unobserved latent states and the unknown model parameters. We apply this novel methodology to five population growth models, including models with strong and weak Allee effects,

Particle motion: the missing link in underwater acoustic ecology [PDF]
Summary Sound waves in water have both a pressure and a particle‐motion component, yet few studies of underwater acoustic ecology have measured the particle‐motion component of sound. While mammal hearing is based on detection of sound pressure, fish and invertebrates (i.e. most aquatic animals) primarily sense sound using particle motion.

Particles, environments, and possible ecologies in the Jovian atmosphere [PDF]
The eddy diffusion coefficient is estimated as a function of altitude, separately for the Jovian troposphere and mesosphere. Complex organic molecules produced by the Ly alpha photolysis of methane may possibly be the absorbers in the lower mesosphere which account for the low reflectivity of Jupiter in the near ultraviolet.

Viral ecology of organic and inorganic particles in aquatic systems: avenues for further research [PDF]
Viral abundance and processes in the water column and sediments are well studied for some systems; however, we know relatively little about virus-host interactions on particles and how particles influence these interactions. Here we review virus-prokaryote interactions on inorganic and organic particles in the water column.

Theoretical Mechanics of Particle Capture: Predictions for Hydropsychid Caddisfly Distributional Ecology [PDF]
Computer simulations based on equations developed earlier were used to analyze theoretically the effects of six parameters on particle capture by hydropsychid caddisfly nets. If assumptions that form the basis of these simulations are valid, the following statements can be made. (1) Nets with fine meshes capture suspended particles at a higher rate per
