However, from an ecological perspective, this is a falsehood, for several reasons, including: a ) Removing most of the trees in a given area is usually done using large machines which disrupt the soil greatly, and the dramatic diminution of ground cover permits large-scale erosion and avalanches, which further damage the habitat and sometimes endangers infrastructure, roads, and communities.

However, others disagree, arguing that a more radical transformation of agriculture is needed, one guided by the notion that ecological change in agriculture cannot be promoted without comparable changes in the social, political, cultural and economic arenas that conform and determine agriculture.

However, in the technical, ecological sense, the constraints are more demanding.

However, because they occur as a result of poorly-constrained ecological interactions usually at depth, the processes that form the biological pump are difficult to measure.

However most progress has been made in the analysis of spatial memory ; some of this work has sought to clarify the physiological basis of spatial memory and the role of the hippocampus ; other work has explored the spatial memory of scatter-hoarder animals such as Clark's Nutcracker, certain jays, tits and certain squirrels, whose ecological niches require them to remember the locations of thousands of caches., often following radical changes in the environment.

However, there have been several detailed ecological studies that showed negligible environmental and health impacts.

However, cavalry saw a role as part of screening forces and in foraging and scouting.

However, conflicts over food are rarely followed by post conflict reunions, even though they are the most frequent type in foraging primates.

However, he was most active throughout the final year of hostilities in much smaller actions focused on harassing British foraging parties near Charleston.

However, the flocks of the species are not stable social units but rather groups that ensure greater safety in numbers and collectively draw each other's attention to ideal foraging and roosting sites.

However, while foraging, if dense vegetation stands between it and humans, this wader can be fairly tame.

However, during migration it was also observed foraging in the tops of trees.

However a fleet of thirteen British ships sailed into Cherry Harbor and began a process of foraging the island and its manor house at will and were to turn it into a private hunting preserve.

However, recent use of animal-born video imaging, temperature / depth recorders, and satellite telemetry has shown that monk seals actually spend much more time foraging in deeper water outside the reefs at subphotic depths of or more.

However, during these periods, the female ’ s foraging ability would be greatly hindered because of constraints placed upon her by the pregnancy itself or the amount of time tending to or minding the offspring.

However, Gray Bats are believed to discriminate somewhat between insects when foraging in their natural habitat, consuming higher numbers of Lepidoptera, Coleoptera, Diptera, and in some populations Trichoptera, than their proportional prevalence would have otherwise indicated without selective foraging .< ref > Best, T. L., B. A. Milam, T. D.

However, the foraging mode of production still exists, and often typified in contemporary hunter-gatherer societies.

However, when the British later withdrew to their ships in the Patuxent, discipline was less effective ( partly because of fatigue ) and there was considerable looting by foraging parties and stragglers and deserters.
