Distribution and Abundance
TLDR
Rodent distribution and abundance in relation to season, habitat, and cover solely in agricultural habitats of Vigo County, Indiana was investigated in this paper, and the specific objective of this report is to relate those findings to explain the occurrence of these rodents in cultivated field ecosystems and to compare their results with those of previous studies to determine what changes, if any, have occurred in the distribution and abundances of these animals in cultivated fields.Abstract:

Ecological Processes That Affect Populations in Complex Landscapes
TL;DR: A general framework for understanding the ecological processes that operate at landscape scales is described and the composition of habitat types in a landscape and the physiognomic or spatial arrangement of those habitats are the two essential features that are required to describe any landscape.

The habitat function of mangroves for terrestrial and marine fauna: a review
Ivan Nagelkerken,Stephen J. M. Blaber,Steven Bouillon,P Green,Michael D. E. Haywood,Lg Kirton,Jan-Olaf Meynecke,Joseph R. Pawlik,Hm Penrose,A. Sasekumar,Pj Somerfield +10 more
TL;DR: In this article, the authors reviewed the literature with regard to the degree of interlinkage between mangroves and adjacent habitats, a research area which has received increasing attention in the last decade.

Plastics and microplastics in the oceans: From emerging pollutants to emerged threat
TL;DR: Investigations on temporal trends, geographical distribution and global cycle of plastics have management implications when defining the origin, possible drifting tracks and ecological consequences of such pollution, and the fate and impact of microplastics in the marine environment are still far to be fully clarified.

Marine fronts at the continental shelves of austral South America: Physical and ecological processes
TL;DR: In this paper, the authors developed a holistic view of physical and ecological patterns and processes at austral South America, regarding frontal arrangements using satellite information (sea surface temperature and chlorophyll concentration), and historical hydrographic data were employed to show fronts.
Journal ArticleDOI
Importance of the riparian zone to the conservation and management of freshwater fish: a review
TL;DR: Attention to the linkages between fish and riparian systems is essential in efforts to rehabilitate degraded stream environments and to prevent further deterioration in freshwater fish populations in northern Australia.

Cleavage of Structural Proteins during the Assembly of the Head of Bacteriophage T4
TL;DR: Using an improved method of gel electrophoresis, many hitherto unknown proteins have been found in bacteriophage T4 and some of these have been identified with specific gene products.
Journal ArticleDOI
The bottleneck effect and genetic variability in populations
TL;DR: In a population of constant size the expected heterozygosity for a neutral locus when mutation and genetic drift are balanced is given by 4 Nv/(4Nv + 1) under the assumption that new mutations are always different from the pre-existing alleles in the population.

The Number of Alleles That Can Be Maintained in a Finite Population
Motoo Kimura,James F. Crow +1 more
TL;DR: This article proposes to examine some of the population consequences of a system of different isoalleles whose frequency in the population is determined by the mutation rate and by random drift, and considers three possibilities: A system of selectively neutral isoallels, a systemof mutually heterotic alleles, and a mixture of heterotic and harmful mutants.

Seasonal changes in oak leaf tannins and nutrients as a cause of spring feeding by winter moth caterpillars
Paul Feeny,Paul Feeny +1 more
TL;DR: The content of oak leaf tannins, which inhibit the growth of winter moth larvae, increases during the summer and may render leaves less suitable for insect growth by further reducing the availability of nitrogen and perhaps also by influencing leaf palatability.
