Journal of Integrative Agriculture, 2016 Ten populations of Radopholus similis from different ornamental hosts were tested for their parasitism and pathogenicity to water spinach (Ipomoea aquatic), malabar spinach (Basella rubra), and squash (Cucurbita moschata) in pots.

Biological Reviews, EarlyView.ABSTRACT From blood‐sucking lice and food‐stealing gulls to pandemic‐inducing viruses and egg‐eating snakes: parasites and predators are ubiquitous in shaping ecology and evolution. Fundamental to these interactions is the way in which parasites and predators choose their victim. Here, I argue that a trade‐off between host quality and vulnerability can

A phase transition for a spatial host-parasite model with extreme host immunities on $\mathbb{Z}^d$ and $\mathbb{T}_d$ [PDF]
arXivWe investigate a model of a parasite population invading spatially distributed immobile hosts. Each host has an unbreakable immunity against infection with a certain probability $p$. We show that, on $\mathbb{Z}^d$ with $d\ge 2$ and the $d$-regular tree $\mathbb{T}_d$ with $d\ge 3$, the survival probability of parasites undergoes a phase transition in ...

Ecosystem services provided by spiders
Biological Reviews, EarlyView.ABSTRACT Spiders, ubiquitous and abundant predators in terrestrial ecosystems, often are the subjects of an unjust negative perception. However, these remarkable creatures stand as unsung heroes within our ecosystems, contributing a multitude of ecosystem services critical to human well‐being.

Opportunities, research gaps, and risks in allogenic ecosystem engineer mimicry
Conservation Biology, EarlyView.Abstract In an age of anthropogenically driven species loss and increasingly novel ecosystems, ecosystem engineer restoration is a process‐based approach to supporting ecosystem function. Many ecosystem engineers have low or declining population sizes.

Beamforming with hybrid reconfigurable parasitic antenna arrays [PDF]
arXivA parasitic reconfigurable antenna array is a low-power approach for beamforming using passive tunable elements. Prior work on reconfigurable antennas in communication theory is based on ideal radiation pattern abstractions. It does not address the problem of physical realizability.

Impacts of bat use of anthropogenic structures on bats and humans
Conservation Biology, EarlyView.Abstract Human‐induced landscape modifications and climate change are forcing wildlife into closer contact with humans as the availability of natural habitats decreases. Although the importance of anthropogenic structures for the conservation of species is widely recognized, negative narratives surrounding bats may impede conservation efforts in human ...
