American Economic Review, 2020 The homes of firm owners are an important source of finance for ongoing businesses. We use UK microdata to show that a £1 increase in the value of the homes of a firm’s directors increases the firm’s investment by £0.03. This effect is concentrated among firms whose directors’ homes are valuable relative to the firm’s assets, that are financially ...

Cougar Dispersal and Natal Homing in a Desert Environment
, 2018 We present a review of cougar dispersal literature and the first evidence of natural (i.e., unmanipulated) homing behavior by a dispersing male cougar (Puma concolor) that sustained severe injuries crossing the northern Mojave Desert.

The Role of Landscapes and Landmarks in Bee Navigation: A Review. [PDF]
, 2019 The ability of animals to explore landmarks in their environment is essential to their fitness. Landmarks are widely recognized to play a key role in navigation by providing information in multiple sensory modalities. However, what is a landmark?

Exclusive vs Overlapping Viewers in Media Markets [PDF]
, 2006 This paper investigates competition for advertisers in media markets when viewers can subscribe to multiple channels. A central feature of the model is that channels are monopolists in selling advertising opportunities toward their exclusive viewers, but

Dynamical modeling of collective behavior from pigeon flight data: flock cohesion and dispersion.
PLoS Computational Biology, 2012 Several models of flocking have been promoted based on simulations with qualitatively naturalistic behavior. In this paper we provide the first direct application of computational modeling methods to infer flocking behavior from experimental field data ...

Relying on known or exploring for new? Movement patterns and reproductive resource use in a tadpole-transporting frog [PDF]
PeerJ, 2017 Animals relying on uncertain, ephemeral and patchy resources have to regularly update their information about profitable sites. For many tropical amphibians, widespread, scattered breeding pools constitute such fluctuating resources.

Impaired bone marrow homing of cytokine-activated CD34+ cells in the NOD/SCID model [PDF]
, 2004 The reduced engraftment potential of hematopoietic stem/progenitor cells (HSPCs) after exposure to cytokines may be related to the impaired homing ability of actively cycling cells. We tested this hypothesis by quantifying the short-term horning of human

So near and yet so far: Harmonic radar reveals reduced homing ability of nosema infected honeybees [PDF]
, 2014 Pathogens may gain a fitness advantage through manipulation of the behaviour of their hosts. Likewise, host behavioural changes can be a defence mechanism, counteracting the impact of pathogens on host fitness.
