Sequences Through The Mist

All animals are social, even if only to the extent of engaging in sexual reproduction and otherwise avoiding each other. Understanding the rules that govern social dynamics in general is a step to understanding our own lives (Axelrod 1984). Everything happens in context, so it is unsurprising that we advocate a contextual approach to studying society. Social relationships are the consequences of entwining sets of events and states, and our aim has been to explore how these may be disentangled through analyzing sequences of changes in time and space. Although some of these analytical approaches may seem daunting through their unfamiliarity, they concern a phenomenon— sequentiality—that not only is at the root of life in the patterning of nucleic acids, but also suffuses every aspect of our daily experience in strings of words and sentences and stories. One story can be told in different ways for different purposes, just as an individual butterfly is expressed differently as larva, pupa, and imago. A metamorphosis in storytelling shows how the perceptions of Robert Henryson, a fifteenth-century Scottish poet, might, for the purposes of measuring the dynamics of mammalian society, be stripped to their essentials. In his Moral Fables, Henryson penned these words:

This country mouse lay flattened on the ground, fearing every minute that she would be killed; for her heart was pounding with strokes of fear, and feverishly she trembled hand and foot. And when her sister found her in such straits, for the sake of pity first she grieved a bit, then comforted her with words as sweet as honey.

It is common for stories to be peppered with anthropomorphism, and one class of these, akin to mock anthropomorphism (Kennedy 1986), enriches prose with insight. Certainly, understanding is not the sole prerogative of those who wield the colorless pen of late-twentieth-century science. On the other hand, another class of anthropomorphism is blind to life's processes and, in its fancifulness, more often than not corrupts literature by diminishing understanding. Stripping out these distractions is a step toward understanding, and interpretation of the essence that remains hinges on the meaning of sequences, whether they be words or behaviors. In the contextual study of animal behavior the narration that precedes or succeeds a given action has equal weight to the action itself. As a step toward such contextual analysis, we might wonder whether Henryson had this in mind:

One rural female wood mouse (Apodemus sylvaticus) adopted a dorsoven-trally flattened posture, exhibiting, in an unspecified but seemingly fearful context, tachycardia and elevated body temperature, and associated tremulous movements of the fore- and hind-paws. These signs appeared to be stress-induced. A conspecific female approached and initiated prolonged nonreciprocal grooming, perhaps with the consequence of diminishing the signs of putative stress. Subsequent molecular analyses confirmed the hypothesis that these individuals were siblings.

The only merit of the aridity of this version is that it exposes the states and events that can usefully be defined in an ethogram and exposes the sequences of those that will become grist for analysis:

(I) ETHOGRAM: crouch: dorsoventral flattened posture with head close to the (i.e., modifier) ground; shake: tremulous movement of body (no modifier), or shaking fore-paw(s) (modifier 1) or shaking hind-paw (modifier 2); approach: one individual moves toward another; groom opposite: one individual grooms the other on the head, or neck, or back, or flank (modifier 1).

(II) SEQUENCE: BEHAVIOR: A-crouch ^ A-shake ^ B-approach-A ^ B-nose-to-nose-A ^ B-groom-A.

MODIFIER 1: ground paw

MODIFIER 2: foot

DURATION: (tj - t0) (t2 - tj) (t3 - t2) (t4 - t3) (tn - t4) SUBJECTS: 2 female wood mice (Apodemus sylvaticus)

Clearly, there are many ways of describing an observation. Henryson's original and our coded version may be quests for different sorts of understanding. The point is that having designed an ethogram and having chosen the correct method of observation, we can distill an observed set of events or states into a pattern that facilitates greater precision of interpretation and decreased risk of fanciful anthropomorphism.
