The average size of boutons became successively smaller in the following fiber groups, vibrissa, guard hair, hairy skin and lip afferents. The present findings that a distinctive morphology in the terminal arborizations has a good correlation with a functional segregation among the cytoarchitectonic...
Climatesacross the world became steadily cooler during that period. Lower ocean surfacetemperaturesreducedwaterevaporation, which slowed the wholehydrologic cycle, with less cloudformationandprecipitation. The vegetation of midlatitude regions, lying between the wet equatorial areas and the moist cool temperate...
Gooseberry bushes are spiny and usually produce greenish to greenish pinkflowersthat are borne singly or in small clusters of two or three. The ovalberriesare white, red, yellow, or green, usually with a prickly or hairy surface. Native to temperate regions of the Northern Hemisphere, gooseberri...
The problem is that competition ordinarily cannot be observed directly but must be inferred from the spread or increase of one species and the concurrent reduction or disappearance of another species. The Russian biologist G. F. Gause performed numerous two-species experiments in the laboratory, in...
(GEE) as described in Table1, identifying grid cells that became unsuitable, damaged, or underwent a change in trend over the last 20 years (between ~2000 and ~2020). These binarized maps were then resampled using the ‘nearest neighbor’ method to the resolution of the climate zone data ...
C New research has found that two similar species of birds-both capable of showing self control through delayed gratification-behave very differently around their favourite food when they have company.Published in the journal PLOS ONE, the study was led by researchers from Angli a Ruskin University...
Two species of deer have been prevalent in the Puget Sound area of Washington State in the Pacific Northwest of the United States. The black-tailed deer, lowland, west-side cousin of the mule deer of eastern Washington, is now the most common. The other species, the Columbian white-tailed...
A native of the Northwestern Hawaiian Islands, the Hawaiian Monk Seal is one of the earless seals that live on warm beaches, unlike other seals. This endangered marine mammal is one of the two remaining seal species—along with the Mediterranean monk seal. The third species from this family,...

It is likely that plant invasions result from complex interactions between species traits, community traits, and abiotic conditions. Despite this, there have been few experimental studies that directly examine these interactions. Two morphologically similar perennial grass species in the genus Cortaderia ...
