Weaponry Investment in the Socially Monogamous Snapping Shrimp Alpheus brasileiro (Decapoda: Alpheidae)

open access: yesActa Zoologica, EarlyView.
ABSTRACT Weapons are morphological structures used by animals in various contexts, especially in intra‐specific contests and visual displays. In snapping shrimps of the genus Alpheus, particularly the monogamous species Alpheus brasileiro, both sexes bear enlarged chelipeds, potentially conferring advantages in mate competition or territorial defence ...

“Yet the Problem Remains”: Why Genetic Determinism Still Haunts Biomedical Research

open access: yesBioethics, EarlyView.
ABSTRACT After the horrors of the Holocaust and its connections to eugenics were revealed to the world, many post‐war population geneticists sought to establish rhetorical distance from the Nazi's state‐led campaigns, without abandoning their belief that actively shaping the population's genetics would produce a prosperous society.

Synthesizing beaver coexistence messaging with the capability, opportunity, and motivation behavior model

open access: yesConservation Biology, EarlyView.
Abstract In the western United States, conservation practitioners are increasingly working with private landowners to restore habitat for North American beavers (Castor canadensis) and to use nonlethal mitigation techniques when beavers damage crops and infrastructure.

Computer simulations on the sympatric speciation modes for the Midas cichlid species complex [PDF]

open access: yes, 2007
Cichlid fishes are one of the best model system for the study of evolution of the species. Inspired by them, in this paper we simulated the splitting of a single species into two separate ones via random mutations, with both populations living together ...

Reproductive consequences of mate retention and divorce in a short‐lived migratory passerine

open access: yesIbis, EarlyView.
In socially monogamous birds, pair‐bond duration varies across species, from single‐breeding associations to long‐lasting, multi‐year bonds. Studies of pair retention and divorce have focused on long‐lived and sedentary species rather than short‐lived and migratory species.

Pairwise Imitation and Tournament Graphs

open access: yesInternational Economic Review, EarlyView.
ABSTRACT This paper investigates strategic dynamics under the behavioral rule of pairwise interact and imitate (PII), which requires minimal information and emphasizes outperforming opponents in pairwise interactions. We characterize PII using weak tournament graphs and, for a broad class of dynamics, establish a one‐shot stability result for ...

Goodness‐of‐Fit Tests for Positive Quadrant Dependence

open access: yesInternational Statistical Review, EarlyView.
Summary When two random variables are positive quadrant dependent (PQD), they are more likely to assume small (or large) values simultaneously compared with when the random variables are independent. This dependence structure is of interest in many areas, including finance, actuarial science and engineering.

Standing on a common ground: a comparison of static stability approaches for pallet loading

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract At the practical level, the static stability constraint is one of the most important constraints in practical pallet loading problems, such as air cargo palletizing. Approaches to modeling static stability, which range from base support and mechanical equilibrium calculations to physical simulation, differ in workflow, focus, and assumptions ...

Morphology of the recently re-classified Tasman masked booby (Sula dactylatra tasmani) breeding on the Kermadec Islands [PDF]

open access: yes, 2010
Once thought to be extinct, the Tasman Booby Sula tasmani has recently been re-classified as a subspecies of the Masked Booby S. dactylatra on the basis of genetic data.
