Survival and extinction results for a patch model with sexual reproduction [PDF]

arXiv, 2013
This article is concerned with a version of the contact process with sexual reproduction on a graph with two levels of interactions modeling metapopulations. The population is spatially distributed into patches and offspring are produced in each patch at a rate proportional to the number of pairs of individuals in the patch (sexual reproduction) rather

Accessible ecophysiological tools for seabird conservation

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 32, Issue 12, Page 1983-2002, December 2022., 2022
Abstract Seabirds are the most endangered avian taxa on Earth, with over a third of species globally threatened. To help slow their decline, conservation physiology seeks to determine how seabird responses to climatic and anthropogenic threats influence demographic processes, but it is not widely utilized in monitoring.

What does it take to evolve behaviorally complex organisms? [PDF]

, 2001
What genotypic features explain the evolvability of organisms that have to accomplish many different tasks? The genotype of behaviorally complex organisms may be more likely to encode modular neural architectures because neural modules dedicated to ...

Institutional learning curve and factors of prolonged operation time of robotic distal pancreatectomy: An analysis of an initial 117 cases

Annals of Gastroenterological Surgery, EarlyView.
This study verified the effective implementation of robotic distal pancreatectomy as the standard approach in our strategic robotic surgical oncology program. Although an institutional learning curve was observed, the robotic surgery program successfully expanded the number of primary operating surgeons while maintaining stable short‐term outcomes ...

Genetic population structure of the critically endangered stellate sturgeon (Acipenser stellatus) in the Black Sea basin: Implications for conservation

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 32, Issue 12, Page 1926-1939, December 2022., 2022
Abstract Stellate sturgeon (Acipenser stellatus) is a species of great conservation concern throughout its range. Over the past century, it has experienced a dramatic decline in abundance and distribution in the Black Sea basin. Information regarding the genetic structure of the species is very limited in the region, despite its crucial importance for ...

The Origin of 2 Sexes Through Optimization of Recombination Entropy Against Time and Energy [PDF]

, 2006
Sexual reproduction in Nature requires two sexes, which raises the question why the reproductive scheme did not evolve to have three or more sexes. Here we construct a constrained optimization model based on the communication theory to analyze trade-offs
