O le poutu: Women's roles and Samoan language nests
Samoan language nests have become well established in New Zealand due to the commitment, support and contribution of the Samoan community, the church, Samoan families, parents and most importantly the efforts of mothers. Their advent has created new settings within which or through which women's …

Exploiting the potential of foam nests produced by Engystomops pustulosus
… frog, Engystomops pustulosus, constructs foam nests which act as incubation chambers protecting the developing eggs and tadpoles from predation and environmental damage. This foam is highly stable and does not harm the eggs, sperm ortadpoles. Amphibians produce a range of proteins and peptides …

Sociable weaver nests as a resource to local animal communities
Animal space use in a landscape generally depends on resources. Facilitation by other species may impact resource availability that can positively influence local species diversity and community structure. Species that significantly change resource availability are often termed ecosystem engineers. …

Prevalence and impacts of ants colonizing active bird nests in Illinois
… birds, mammals and social insects, build nests which create unique and suitable microhabitats for a variety of other animals. These constructed environments can protect their residents from predation and from harmful abiotic conditions. In turn, the communities of arthropods that colonize …

Snakes as predators of bird nests: now and in a warming world
… were the dominant snake predator of bird nests (28% of recorded nest predation) followed by corn snakes (E. guttata: 15%), black racers (12%), and coachwhips (Masticophis flagellum: 3%). In addition to monitoring 206 bird nests with video cameras to determine their fates, I simultaneously …

The geochemistry of fossil termite nests in Calitzdorp, Western Cape, South Africa
… nutrient-rich materials to construct their nests, known as termitaria. Certain termite species also fortify their termitaria using a combination of saliva and excrement (frass), resulting in geochemically distinct termitaria relative to the host soils. The enrichment of exchangeable bases …

Code Optimization in the Polyhedron Model - Improving the Efficiency of Parallel Loop Nests
A safe basis for automatic loop parallelization is the polyhedron model which represents the iteration domain of a loop nest as a polyhedron in $\mathbb{Z}^n$. However, turning the parallel loop program in the model to efficient code meets with several obstacles, due to which performance may …

Relations between forest and prairie fragmentation and depredation of artificial nests in Missouri
"Human settlement of native ecosystems has resulted in the destruction and fragmentation of habitats until, in many cases, only isolated remnants remain. The emerging field of conservation biology often examines these fragments, attempting to illucidate patterns of diversity, the mechanisms that …

Using Conditioned Food Aversion (CFA) to reduce Pied Crow (Corbus albus) predation of plover nests
… which animals are deliberately induced to avoid nests following consumption of eggs treated with an illness-inducing toxin. Previous studies suggest that this technique is effective but many have been subject to several methodological flaws that limit their applicability. Here I employ an …

The costs and benefits of hosting colonial sociable weaver nests for arid zone savanna trees
… a nest. I found that soils under trees without nests were characterized by higher N (2.3-fold) and P (1.3-fold) compared to grassland areas. However, I found that soils under nest trees had even higher concentrations of N (3.5-fold) and P (4.1-fold) than soils under trees without nests. …

Hydraulic Characterization of Mounded Gravel Fish Nests: Incipient Motion Criteria and Despiking Acoustic Doppler Velocimeter Data
… engi- neer that constructs mounded gravel nests for spawning. Chubs provide benefits for other spawning fishes, predators, and benthic organisms through their nest construction. This study seeks to apply sediment transport models to find incipient motion criteria and erosion susceptibility …

Effects of Temperature and Dissolved Oxygen on Development and Survival of Embryos in Nests of Bluehead Chub Nocomis leptocephalus
… patterns highlight that embryos in communal nests are highly sensitive to modest environmental changes, particularly because they cannot behaviorally avoid unfavorable conditions. As stream temperatures rise and oxygen levels fluctuate with climate change, the narrow environmental window …

Demography, cold hardiness, and nutrient reserves of overwintering nests of the carpenter ant Camponotus pennsylvanicus (De Geer) (Hymenoptera: Formicidae)
Overwintering nests of C. pennsylvanicus were dissected and censused. All castes were assayed for glycerol and for changes in nutrient reserves. Spring queens were collected at swarming and allowed to initiate nests. Queens were analyzed for nutrient reserves during the early stages of nest …

Impacts of Vegetation Density and Distance from the High Tide Line on Raccoon Predation of Diamondback Terrapin Nests in Jamaica Bay, NY – A preliminary study
… impact on predation of diamondback terrapin nests by raccoons. For that, terrapin scented water was used to construct 50 artificial nests at Jamaica Bay Wildlife Refuge. These artificial nests were placed in areas differing in vegetation coverage and distance from the high tide line, and …

Nesting Ecology of the Ring-necked Pheasant in Eastern South Dakota
… and 16-30 June, respectively. Average density of nests was 0.3 per hectare in 1973 and 0.2 in 1974. Average clutch size for combined years was 8.6 for all nests and 10.8 for nests where clutches hatched. Clutch sizes declines as the nesting season progressed. Fertility of eggs in nests where …
