Does alliance restraint happen in international affairs? What theories explain the success or failure of restraint efforts? Do states ever form alliances in order to restrain? Alliance restraint - an actual or anticipated diplomatic effort by one ally to influence a second ally not to proceed with …

Adaptive Endocrine Changes in a Natural Population of Brown Lemmings (Lemmus Trimucronatus) During the Summer of 1969
… about cyclic populations of Norwegian lemmings- (Lemen), mice (Mus), and "rodent" (Smagnagere) which reaches as far back as 1578. This information supports the assumption that cyclic populations have probably been in existence for many hundreds of years. However, documented proof of …

The Effects of Social Stress on Reproduction in a Wild Deermouse Population (Peromyscus Leucopus)
… However, his account of suicidal migrations of lemmings was based on legend, as were the accounts of periodic erruptions of house mice, rats and voles. Since then, many investigations have presented conflicting ideas on the causes of density cycles in small mammalian populations. | Cyclic …

Les colonies d'oies peuvent-elles affecter l'activité du renard arctique (vulpes lagopus) à l'échelle circumpolaire?
… les espèces de proies résidentes telles que les lemmings peuvent supporter, nous avons étudié l'impact de la présence d'une colonie d'oies sur l'indice d'activité du renard arctique (Vulpes lagopus) à une échelle circumpolaire. Nous avons émis l'hypothèse selon laquelle la présence de subsides …

Small mammal communities on a reclaimed mountaintop mine/valley fill landscape in southern West Virginia
… house mice (Mus musculus), southern bog lemmings ( Synaptomys cooperi), and masked shrews (S. cinereus) were more common in reclaimed treatments. These species were generally found in expected habitats. Allegheny woodrats (Neotoma magister) occupied drainage channels, a habitat use not …

Design of a prototype autonomous amphibious WHEGS robot for surf-zone operations
… years in development based on the Foster Miller lemmings platform. This platform, in conjunction with a commercial off-the-shelf (COTS) control architecture, is capable of autonomous, land based waypoint navigation, self orientation, and rudimentary obstacle avoidance. It can receive waypoint …

BERINGIAN BIOGEOGRAPHY: PATTERNS OF INTERCONTINENTAL DISPERSAL AND THE STRUCTURING OF A HOLARCTIC TAPEWORM GENUS
… during the colonization event associated with lemmings,<em> </em>the direction of <em>Arostrilepis </em>colonization may have been counter to that of its hosts. These results highlight the complex history of faunal assembly associated with Beringian mammal-parasite assemblages.</p>

Effect of Food Availability and Predation on the Population Dynamics and Spacing Behavior of Prairie Voles
Microtine rodent (lemmings and voles) populations often undergo seasonal or multi-annual fluctuations in density. Although a number of single factors have been proposed as the causal agent of these fluctuations, no one has demonstrated convincingly that a single-factor mechanism is responsible. …

Mechanistic underpinnings of lacustrine brGDGT production, and proteomic vertebrate taxonomic identification of phrynosomatid lizards and arvicoline rodents
… to North American arvicoline rodents (voles, lemmings and muskrats) to assess the rate of amino acid substitution of COL1 in a rapidly diversified clade. Each of these topics of research resulted in a meaningful alteration of scientific understanding of the mechanisms underpinning …

The Role of Plant Chemical Defenses in The Nutritional Ecology of Voles
… density of microtine rodents (voles and lemmings), the impact of secondary plant compounds on forage quality is largely unknown. This thesis reports results of studies conducted to examine the effects of plant chemical defenses on the individual performance, food habits, and population …

Impacts de la variabilité climatique sur les interactions prédateur-proie en Arctique
Les interactions entre espèces sont essentielles au fonctionnement d’un écosystème. Une des relations interspécifiques clés réside dans la relation entre un prédateur et sa proie. En plus de ce lien trophique direct, des liens indirects (apparents) entre les deux proies (c’.-à-d., compétition et …
