Uncovering Biogas Outcomes: Tales of Hubris, Hope, and Failure From Southern Malawi

Natural Resources Forum, EarlyView.
ABSTRACT The purpose of this article is to speak directly to biogas failure. Over the past two decades, immense amounts of money have been spent by African governments, private individuals, and most conspicuously, international aid agencies and donors, on countless biogas projects in every country on the continent.

Stable flies preferentially oviposit on sites offering conspecific eggs with egg‐derived bacterial semiochemicals

Insect Science, EarlyView.
Stable flies preferentially oviposit on sites offering conspecific eggs with egg‐derived airborne semiochemicals. Egg‐borne bacterial symbionts, and Serratia marcescens in particular, produce odorants which attract gravid female flies and elicit oviposition.

A horizontally transferred bacterial gene for pantothenic acid biosynthesis regulates diapause and reproduction in the spider mite Amphitetranychus viennensis

Insect Science, EarlyView.
A bacterial‐derived AvPBL gene encoding a pantothenate‐β‐alanine ligase was identified in Amphitetranychus viennensis. RNAi silencing of AvPBL reduced pantothenic acid production, impairing reproduction and diapause induction, while pantothenic acid supplementation rescued these phenotypes.

Does Rodent Management Impact the Distribution of Rattus rattus and Mastomys natalensis in Village Settings?

Integrative Zoology, EarlyView.
Ecological differences between species may result in differential impacts of control measures. Our experimental study showed that intensive removal of rodents from houses (mostly Rattus rattus) resulted in increased use of houses by Mastomys natalensis, a species usually found outdoors. Our results suggest that M.

Intra‐ and Interspecific Effects on Spatio‐Temporal Behavior of Common Commensal Rodent Species

Integrative Zoology, EarlyView.
This study revealed major findings on spatio‐temporal behavior of commensal rodents on a pig farm showing the influence of interspecific dominance on movement behavior and the resulting species‐specific ecological adaptations. Additionally, rodents tend to stay in their home ranges and migration to other stable buildings is only rare.

From Data to Knowledge to Wisdom: Lessons Learned From the Vancouver Rat Project

Integrative Zoology, EarlyView.
A synthesis of 15 years of research conducted by the Vancouver Rat Project revealed that: (1) Pathogen ecology within rat colonies is the result of complex interactions among rats, pathogens, and vectors. (2) Local and global population structures influence rat and pathogen ecology.

Baseline Cortisol and Behavioral Phenotype Are Linked to Context‐Dependent Spatial Cognition and Space Use in Giant Pandas

Integrative Zoology, EarlyView.
Baseline cortisol and repeatable behavioral phenotypes were associated with context‐dependent spatial cognition in giant pandas. Individuals differed in spatial search performance under stable and changing resource conditions. Exploratory GPS analyses revealed directionally consistent but non‐significant patterns of space use in novel environments ...
