We considered the relationship between the benefits and costs of territorial defense in a wild population of the Leon Springs pupfish, Cyprinodon bovinus. We defined benefit as the number of eggs deposited on an artificial substratum placed within the defender's territory. Costs included two defensive behaviors.

Temporary gains and permanent costs in methamphetamine precursor control.

Int J Drug Policy

June 2024

Department of Economics, Baylor University, Waco, TX, United States. Electronic address:

James Cunningham and co-authors did pioneering work in evaluating the impact of precursor control on methamphetamine markets and related harms. We discuss their studies, as well as others that followed, and review what is known of precursor control's short-run and long-run impacts. We interpret the evidence to suggest that precursor control was likely cost-effective initially.

Adherence to the Mediterranean diet has been shown to lower the risk of developing chronic non-communicable diseases like cardiovascular and neurodegenerative diseases and cancer. Improvements in depression, participation in daily activities in older individuals, weight loss and a reduction in adverse pregnancy outcomes are associated with adherence to the Mediterranean diet. The number of studies that have evaluated barriers to adherence to the Mediterranean diet in the US and, in particular, in racial and ethnic minority populations within the US are few.

Body size is a trait that shapes many aspects of a species' development and evolution. Larger body size is often beneficial in animals, but it can also be associated with life history costs in natural systems. Similarly, miniaturization, the evolution of extremely small adult body size, is found in every major animal group, yet carries its own life history trade-offs.

Article Synopsis
  • Research indicates that many dog owners resort to behavioral euthanasia due to serious behaviors in their pets, with little existing literature on this topic.
  • The main reasons for euthanasia include human-directed aggression, particularly towards household members, and aggression towards other pets, often following severe biting incidents.
  • There is a need for more research to explore the underlying factors behind these behaviors and to assess the impact of euthanasia on pet owners, which can aid in improving behavior intervention strategies and fostering a better understanding of animal behavior.

Sexes often have differing fitness optima, potentially generating intra-locus sexual conflict, as each sex bears a genetic "load" of alleles beneficial to the other sex. One strategy to evaluate conflict in the genome is to artificially select populations discordantly against established sexual dimorphism (SD), reintroducing attenuated conflict. We investigate a long-term artificial selection experiment reversing sexual size dimorphism in Drosophila melanogaster during ~350 generations of sexually discordant selection.

A prior randomized trial found a school social intervention yielded significantly better outcomes (social and autism features) immediately following intervention compared to typical school programming (services-as-usual [SAU]) for children on the autism spectrum. In that study, children in the SAU condition subsequently completed a summer social intervention. This study tested longer-term maintenance of effects for children who completed both interventions.

Temperature has been shown to have profound effects on mosquito population dynamics and life history. Understanding these effects can provide insight into how mosquito populations and the diseases they transmit may vary across space and time and under the changes imposed by climate change. In this study, we evaluated how temperature affects the blood feeding and general activity patterns in the globally invasive mosquito species .
