we estimated summer ranges based on annual samples of 22–44 caribou (40–229 locations / caribou), and winter ranges based on annual samples of 18–44 caribou (48–298 locations / caribou). we estimated 106 spring and 88 fall migration paths involving 52 individual caribou. we observed 64 instances (25 and 39 for spring and fall, respectively; table 1) where movements of a caribou during spring or fall did not fit our definition of migration; thus, we did not estimate migration paths for those caribou during those seasons. these caribou did not demonstrate a distinct migratory behavior pattern (i. e. , they had overlapping summer and winter ranges and their movements between seasonal ranges were irregular and less directed) .

from april 8 - september 8, 2003, filmmaker leanne allison and wildlife biologist karsten heuer migrated on foot with the caribou herd, to see for themselves if the calving grounds are important to the survival of the herd. being caribou was the name of the expedition. now it is the name of the intimate, funny, informative, compelling and award - winning film we are asking you to watch .
most cah caribou were migratory, and we found relatively little overlap between summer and winter ranges, especially considering that the 90% ud isopleths that we used to define ranges encompassed areas of relatively low use by caribou. caribou whose movements did not fit our strict definition of migration also used different ranges between seasons, although these ranges often overlapped more than those of migratory caribou .

very well written account of the migrating caribou. the calving grounds are in the arctic wildlife national refuge. the book and the message is as important now as when it was written. while canada has protection for caribou - in yukon, ivvavik np but hunting is allowed on the us side. with the proposed opening to oil and gas exploration under the current administration the caribou are in major danger of being the victims as their calving grounds will be right where the drilling will take place - and this could well be the end for them. read the book and become an activist for preserving wilderness .

in north america, many populations of caribou (rangifer tarandus) are known or suspected to make seasonal migrations [ 13 – 17 ]. caribou migration routes are often located in areas where shallow or hard snow or frozen rivers and lakes facilitate travel [ 18 – 21 ], and adverse snow conditions may delay migration by hindering caribou movements [ 22 ]. to accommodate spatial variability in environmental conditions, natural selection has likely favored caribou that follow migration routes that proved successful during previous years [ 22 ]. in such cases, young caribou may learn by following older, experienced animals [ 23 ]. such reliance on traditional migration routes might delay or reduce the ability of caribou to adapt to environmental changes .

manifesto point # 4: work closely with the community partner, but respect each other’s expertise and independence. some people have called my filmmaker - in - residence role as “embedded” in the hospital. i have serious concerns about the term “embedded, ” especially in the context of journalists working within the confines of the u. s. army in the war in iraq. but i can’t help but draw some parallel to the work of leanne allison and karsten heuer, who “embedded themselves” amongst a herd of migrating caribou in the film being caribou (2004), directed by leanne allison and diana wilson. in their efforts to understand the fragile yet resilient porcupine caribou, it’s pretty clear that all parties truly respected each other’s expertise and independence .

we defined winter as the period between the end of fall migration and the beginning of spring migration, and summer extended from the end of the calving period to the start of fall migration. we determined the calving season by observing collared caribou daily (weather permitting) during the first 2 weeks of june and determining when calves first were observed accompanying the collared animals [ 37 ]. caribou that produced calves confined their movements to areas < 1. 5 km 2 for periods of 10–14 days following the calf’s birth (this study, unpublished data). for most caribou, summer began when caribou moved beyond the small area used during calving. however, we observed 8 cases of collared caribou that did not produce calves or exhibit restricted movements during the calving period. for these animals, we modeled summer ranges beginning with the mean date of the end of calving by caribou that produced calves .

because of the dynamic nature of caribou movements, identifying important areas or habitats used for particular behaviors is difficult and may be influenced by decisions regarding how to define specific movement patterns. for example, we found that caribou movements during migration were too variable to enable us to use a single model for identifying migratory movements of all individuals (e. g. , [ 78 ]). instead, we utilized multiple sources of information, including characteristics of the caribou movements themselves, to assign movements to different seasons [ 79, 80 ]. although defining migration based largely on movement patterns of the caribou being studied was useful for identifying geographic areas used for this activity, such subjective decisions might influence the results of studies that attempt to identify factors that influence migration behavior or compare movements among different populations. however, changes in patterns of space use by animals in response to external stimuli can reveal underlying habitat requirements, energetic constraints, or other ecological relationships. thus, studies that assess variation in movement patterns, rather than assuming consistency in range use and movements, can provide valuable insights into a species’ habitat relationships and management requirements .
long - term changes in climate are also likely to affect migratory patterns and create challenges to the management of migratory species [ 70, 71 ]. in the case of migratory caribou, the availability of highly - nutritious, new vegetation during spring coincides with the conclusion of spring migration, initiation of calving, and subsequent formation of large post - calving aggregations [ 72 ]. thus, changes in temperature, precipitation, and environmental productivity that affect the emergence of new vegetation are likely to induce major range shifts during spring [ 4, 71, 73 ]. the variability we found in caribou winter range use suggests that caribou might change their use of winter range in response to changing climatic conditions. such behavioral flexibility is likely to be a positive trait in the face of future energy development and potential climate - driven changes in caribou habitat and resources. therefore, management efforts intended to identify and protect important caribou habitats should be sufficiently flexible to accommodate such changes in behavior. additional studies are needed to assess the causes and significance of inter - annual changes in caribou distribution and to determine how much area is needed to enable caribou to select seasonal ranges based on varying environmental conditions (weather, forage abundance and quality, etc .) .

caribou movements during migration are likely influenced by the search for optimal forage or for conditions that favor travel, and availability of these conditions varies with snow conditions [ 74 ]. although empirical evidence indicating the demographic consequences of fragmenting migration routes or converting them to unusable habitat is limited [ 75 ], increased development along caribou migration routes could have negative energetic effects if migratory movements are impeded or deflected to less - optimal areas. effects of disturbance may be most important for female caribou, because increased energetic costs of migration may cause females to arrive in the calving areas in poor condition reducing the likelihood of survival of both the female and her offspring [ 56, 76 ] .

a great adventure: a husband and wife: biologist karsten heuer and filmmaker leanne allison follow the famed porcupine herd of caribou from its yukon winter range to its calving grounds in the arctic national wildlife refuge and back, thousands of miles. even more mosquitoes. grizzly bears. blizzards. months of walking. ultimately they tapped into the herd’s “infrasonic resonance on the edge of human hearing. ” a sort of oscillating song the collective caribou hummed to stay in touch, a group song
caribou began spring migration near the beginning of may during all years (table 3), and mean duration of migration was 14. 72 days (table 4). fall migration was initiated in mid - september and mean duration was 12. 54 days (table 4). migration routes estimated by averaging bbmms of individual caribou overall years and by overlaying routes from different years produced similar results, and both methods indicated several areas of concentrated use (figs 5 and 6) .
an unforgettable look into the world of northern caribou and the delicate ecosystems they inhabit. heuer does an amazing job of describing his (and his wife' s) journey as they attempt to travel with the porcupine caribou on their annual migration. the book will also resonate if you are an adventure or wilderness junkie. fording half frozen rivers, scaling mountains, grizzly bear encounters, and eating ground squirrels when on the brink of starvation are just a few of the activities they endure d

timing and distances moved by the cah during spring migration were similar to those reported for the porcupine herd [ 43, 44 ]. our data also support the observations of cameron and whitten [ 47 ], who described the movements of the cah during fall migration as more directed and rapid compared to spring migration. this difference might be partly due to differences in weather and environmental conditions, especially characteristics of the snowpack. during early spring, snow cover in northern alaska is extensive and deep snow may restrict or slow caribou movements [ 19, 22 ]. during spring migration, caribou are in the poorest physical condition of the year and pregnant females face high energetic demands of gestation [ 66 ], which may further reduce their ability to travel rapidly. conversely, fall migration typically occurs before deep snow has accumulated, and caribou movements are relatively unimpeded. bergerud et al. [ 67 ] observed similar differences in movement rates between spring and fall migrations of caribou in eastern canada, which they attributed to seasonal differences in food availability .
most visualization approaches in r (e. g. , base, rgooglevis, ggplot2, rgl) are not optimized for speed or modularity. rather, they are designed to build publication - quality or interactive figures that do not need to be redrawn hundreds or more times in rapid succession. plotting requirements for many other uses, including simulation modeling, are different. changes to data, maps, objects can happen rapidly and repeatedly. visualizing this can be critical, especially during the model building phase. furthermore, no plotting method has been designed for modularity – the ability to plot something without being aware of what is already there .

it was hard to know it was happening at first, or maybe we just didn & apos; t want to admit it. the week and a half of rest at the calving grounds, followed by another week of leisurely roaming the alaskan foothills with caribou mothers and newborn calves, had been a welcome break from the intense travel of the spring migration. but now, with group after group racing past our camp in the egaksrak valley, there could be no question that the next phase of the caribou & apos; s migration was on. there was new urgency to their movements, the year & apos; s first mosquitoes and flies were about to hatch and when they did, the caribou would likely band together in huge groups and race for relief in the windy yukon mountains. deemed by many to be the most dramatic stage of the entire migration, the post - calving aggregation was something we didn & apos; t want to miss. packing up just an hour after pitching camp, leanne and i passed on sleep that night and followed the caribou east .
a true story written like fiction, very easy to read. lots of information about caribou and their habitat, but not at all in a textbook or preachy way. the landscape descriptions are good, but obviously cannot do the story justice. i really enjoyed reading about their trek, finding and following and losing (rinse, repeat) caribou. there is an excellent sense of ecology and of a world that is bigger than humans. it reminds me of what is out there, what we have lost, what we could protect .
we try to be caribou but are continually pulled back by our human needs
writes the author in one of his diary entries. what value does it have to follow the migration of a herd of caribou as they head toward calving grounds on the arctic ocean, something that the author and his wife do with great hardship and considerable personal danger? that is the question that this non - fiction book tries to answer, and it may be a kind of religious answer that is discovered. the caribou herd is completely unknown to most of humanity, but for those who study their amazing and instinctive behavior, what results is a kind of mindfulness and awareness. humanity is not at the center of the universe; it is only one small part and all the other parts should be approached with awe and respect .

why anwr must be preserved husband and wife team of karsten heuer and leanne allison decide to spend their honeymoon in just about the most off - the - beaten - track way possible: they' re going to migrate with caribou. not just any caribou, but the porcupine herd of northern canada and alaska, the herd whose calving ground is the 1002 section of the arctic national wildlife refuge, the place where exxon wants to drill to get what will likely be less than six months, maybe one year' s worth of u. s. needs
karsten heuer and his new wife, leanne allison, a filmmaker, spend months following and relating to caribou. they follow the porcupine caribou herd in the spring from their wintering areas to the birthing grounds and back out. they encounter natives on both sides of the oil / environmental refuge question, grizzly bears, birds of all types, wolves, mosquitos and other life. they almost starve, have trouble keeping up sometimes and have moving experiences. an amazing and moving book. they have a website: urltoken and the film has won many awards. definitely worthwhile .
these gp * parameters will specify plot parameters that are available with gpar (). gp will adjust plot parameters, gptext will adjust title and legend text, gpaxis will adjust the axes. size adjusts point size in a spatialpoints object. these will persist with the original plot call for each individual object. multiple entries can be used, but they must be named list elements and they must match the... items to plot. this is true for a rasterstack also, i. e. , the list of named elements must be the same length as the number of layers being plotted. the naming convention used is: rasterstackname $ layername, i. e, landscape $ dem .

sample sizes were the numbers of migration routes of individual caribou modeled during each season (88 and 106 for fall and spring, respectively). summer extended from the end of calving to the beginning of fall migration; winter extended from the end of fall migration to the beginning of spring migration .

this was an amazing movie and shows us the importance of making sure that we need to keep this conversation going and to let everyone know that bush still doesn' t know and understand the impact of the life of the caribou has on everyone of us. thanks so much for not giving up .
the land feels empty without them, the valleys vacant, as though the long history that has terraced every hillside and mountain has abruptly ended. when the caribou aren & apos; t around, one of this landscape & apos; s shaping elements is missing; something as powerful as wind and water .
north american caribou are commonly assigned to herds, based on the traditional use of seasonal ranges, particularly areas used during the calving season [ 24 – 26 ]. in northern alaska, 4 herds of barren - ground caribou (r. t. granti) have been identified. recent (2008–2011) estimates of abundance of these herds were 55, 000 for the teshekpuk lake herd, 67, 000 for the central arctic (cah), 169, 000 for the porcupine herd, and 348, 000 for the western arctic herd (alaska department of fish and game, fairbanks, ak, unpublished data) .
for the first time in three months, we have a sense of what this land might be like without the caribou; what it might be like if short - sighted human greed and the quest for more, faster, bigger modern conveniences lead to oil and gas development in the herd & apos; s alaskan calving grounds .
if new = true, a new plot will be generated, but only in the figure region that has the same name as the object being plotted. this is different than calling clearplot (); plot (object), i. e, . directly before creating a new plot. clearplot () will clear the entire plotting device. when new = false, any plot that already exists will be overplotted, while plots that have not already been plotted will be added. this function rearranges the plotting device to maximize the size of all the plots, minimizing white space. if using the rstudio ide, it is recommended to make and use a new device with dev (), because the built in device is not made for rapid redrawing. the function is based on the grid package .
this film really touched me - caribou are such persistent and beautiful sentient beings. it' s important to take a hard look at how humanity disrupts the fragile ecosystem around us and get the message out there that there are consequences to our irreparable actions. i thank the film makers for their journey and for creating such a captivating and essential documentary .
this film presents undeniable evidence that gives the lie to then sen. frank murkowski' s (r - alaska) disgenuous description of the refuge as
flat, unattractive, not pristine
as he held up a piece of blank white foam board. watching the caribou migrate suggests a more appropriate analogy. the arctic national wildlife refuge is america' s serengeti .
identifying the geographic areas used by the cah during different seasons is needed to determine effective conservation measures and guide planning for future development of roads and infrastructure related to extraction of oil, gas, minerals, and other resources in northern alaska. in addition, differences in areas used between seasons or among years may suggest environmental forces that affect caribou movements. conversely, consistency in use of a particular area, either across seasons or during the same season of different years, may indicate important habitats. thus, assessing fidelity in range use may indicate important habitats or suggest directions for future studies. our objectives were to develop models to estimate and quantify summer (post calving season) and winter ranges of the cah; identify geographic areas used during spring and fall migrations; and assess annual variation in seasonal ranges and migratory movements. we also estimated several metrics describing timing, distance, and rate of movement during migration, which may be useful as baseline data or for comparison with other populations. we restricted our study to movements of adult female caribou, because caribou herd designations are generally based on movements and selection of calving areas by females .
i loved it, honestly i' m not going to go in depth as i believe (cliche yes) that this book can stand on it' s own, and the title says enough. so if you want to read about the caribou and how fundamentally' human' we are then i would recommend this book. hopefully you will enjoy it as much as i did .

one of the main purposes of the plot function is modularity. the goal is to enable any spades module to be able to add a plot to the plotting device, without being aware of what is already in the plotting device. to do this, each open plotting device has a corresponding. quickplot object in the. quickplotenv, that gets created when a first plot function is called. this object keeps the layer names, their extents, and whether they were in a rasterstack (and a few other things). so, when a new plot is called, and new is used, then it will simply add the new layer. there may not be space on the plot device for this, in which case, everything will be replotted in a new arrangement, but taking the original r objects. this is different than the grid package engine for replotting. that engine was not designed for large numbers of plots to be added to a region; it slows down immensely as the number of plots increases.
