Arboreal twig-nesting ants form dominance hierarchies over nesting resources. [PDF]

open access: yes, 2019
Interspecific dominance hierarchies have been widely reported across animal systems. High-ranking species are expected to monopolize more resources than low-ranking species via resource monopolization. In some ant species, dominance hierarchies have been

NESTING AND SURVIVAL OF RIO GRANDE TURKEYS IN NORTHCENTRAL TEXAS

open access: yesWildlife Society Bulletin, 2000
: We studied survival and habitat use of female Rio Grande turkeys (Meleagris gallopavo intermedia) during the nesting period in the Rolling Plains and Cross Timbers ecotone of northcentral Texas.

Intelligent nesting system [PDF]

open access: yesYugoslav Journal of Operations Research, 2003
The economy of the process for the manufacture of parts from sheet metal plates depends on successful solution of the process of cutting various parts from sheet metal plates. Essentially, the problem is to arrange contours within a defined space so that

Ants that Frequently Colonize Twigs in the Leaf Litter of Different Vegetation Habitats

open access: yesSociobiology, 2018
Ants often colonize twigs in the leaf litter, but some species use this resource more frequently than others. We analyzed the composition of the community and the diameter of colonized twigs to test if any species had a size preference.

Nesting and Dressing [PDF]

open access: yes, 2007
We compute the anomalous dimensions of field strength operators Tr F^L in N=4 SYM from an asymptotic nested Bethe ansatz to all-loop order. Starting from the exact solution of the one-loop problem at arbitrary L, we derive a single effective integral ...

Burrow Construction From the Ground Surface in \u3ci\u3eLyroda Subita\u3c/i\u3e (Hymenoptera: Sphecidae) [PDF]

open access: yes, 2017
Plasticity in the nesting behavior of Lyroda subita, a species that renovates and then uses pre-existing burrows and other subterranean cavities for nesting sites, is illustrated by one female which apparently excavated her burrow from the ground surface.

Notes on the Nests of \u3ci\u3eAugochloropsis metallica fulgida\u3c/i\u3e and \u3ci\u3eMegachile mucida\u3c/i\u3e in Central Michigan (Hymenoptera: Halictidae, Megachilidae) [PDF]

open access: yes, 2017
Notes on the nesting biology of two ground-nesting species are provided from Central Michigan. A single nest of Augochloropsis metallica fulgida was excavated on 12 July 2014 in Shiawassee County. There were two female nest inhabitants.

Using Predator Exclosures to Protect Ground Nests from Red Fox

open access: yesHuman-Wildlife Interactions, 2017
Nest predation often is cited as a primary cause for low recruitment and subsequent population decline of many ground-nesting bird species. In response, managers and researchers have developed a myriad of techniques to reduce rates of predation on ground

Arc-Coloured Permutations [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2013
The equidistribution of many crossing and nesting statistics exists in several combinatorial objects like matchings, set partitions, permutations, and embedded labelled graphs.
