momentum movement ecology

This was always a distortion of Darwin, first because evolution has to do with long-term survival of species, not individuals within a species, and second because there are many examples of organic “solidarity” both within and between species. Movement promotes diversity both directly through species’ own mobility patterns and indirectly through mobile-link functions of moving animals [13]. Organizations, affinity groups, and individuals whose work is in line with these or similar values – for the left we might call this “radical ideology” – are part of the Movement.

Despite its problems, however, the ecological lens brings into focus a prefigurative vision for the way social movement groups interact with one another within a broader Movement. 2020 It ... Naess has said that “The main driving force of the Deep Ecology movement, as compared with the rest of the ecological movement, is that of identification and solidarity with all life.” I think what is being said here, is that we humans are part of the natural world, not separate from it. [2] In the past few years, the popular Momentum Training program, which coaches activists in approaches to movement-building, has been promoting a concept of social movement ecology (SME) to describe why a particular organization does not have to “do it all,” but rather how each approach to change fits into an “ecosystem” of movement groups. Being launched as a declared discipline only about 10 years ago [ 17 ], movement ecology has developed much technology and analytical tools to decipher how animals integrate information about their environment, experience, and innate states to make movement decisions [ 5 , 9 ]. While movement HMMs typically rely solely on location data (e.g. Interestingly, this model suggests step lengths and directional persistence for the “encamped” state decreased as temperature increased, step lengths for both states tended to decrease in the late evening and early morning, and transition probabilities from the “encamped” to “exploratory” state decreased as temperature increased (Figure 3). Attempts to use SME should thoroughly consider which types of groups and people are part of the envisioned “ecology,” how each of them impacts that “environment,” and how they interact with one another to access resources. This connects to a deeper problem in adapting the ecological metaphor to social movements: the bird’s eye view of populations is a descriptive model. Both methods gave similar results for the tolerant species but not for the sensitive ones. Movement ecology provides a unifying framework, based on first principles, for studying the movement of organisms. Trends Ecol Evol. 2020. Authors: Steven J. Hromada, Todd C. Esque, Amy G.

These states are often considered as proxies for animal behaviour and characterized by area‐restricted‐search‐type movements (“encamped” or “foraging”) and migratory‐type movements (“exploratory” or “transit”). Estimated activity budgets for the 5 states of this multiple‐imputation HMM were 0.28 (0.28–0.29) for the “Abertay” haul‐out state, 0.12 (0.11–0.14) for the “Farne Islands” haul‐out state, 0.37 (0.35–0.38) for the “Dogger Bank” foraging state, 0.09 (0.04–0.18) for a low‐speed “exploratory” state, and 0.14 (0.09–0.22) for a high‐speed “exploratory” state. Animal movement: statistical models for telemetry data. At very least, the environmental conditions for a SME need to be envisioned so that “survival” incorporates the goal of the movement. Some common probability distributions for the step length data stream are the gamma or Weibull distributions, while the wrapped Cauchy or von Mises distributions are often employed for the turning angle (e.g. However, complex movement or observation process models often necessitate custom and computationally demanding HMM model‐fitting techniques that are impractical for most practitioners, and there is a paucity of generalized user‐friendly software available for implementing multivariate HMMs of animal movement. The two remaining contributions address evolutionary aspects. Second, alternative institutions attempt to prefigure organizing models based on radical principles (e.g., cooperative businesses, communes). Many felid species are of high conservation concern, and with increasing human disturbance the situation is worsening. Spatio-temporal patterns of foraging behaviour in a wide-ranging seabird reveal the role of primary productivity in locating prey. Disagreements between the three approaches to social change that Momentum theorizes (i.e. 2000. Ecology is concerned with the harmony of interacting species of organisms, not with the experience of any given organism in the ecosystem. (2014), with periods of “foraging” often followed by “resting” at sea (Figure 4).

How predators respond to this prey patchiness may have consequences on their foraging success, and thus physical condition. B.T.M. © 2020 BioMed Central Ltd unless otherwise stated. Because the seal repeatedly visited the same haul‐out and foraging locations, it provides an excellent example for demonstrating how biased movements relative to activity centres can be modelled using momentuHMM. As discussed and exemplified by Jeltsch et al. Momentum’s SME is based on there being three broad approaches to social change (dominant institutional change, alternative institutions, and personal transformation), so in order to qualify as one of them, a group or individual must desire change, and take action to achieve it. In the “natural world” there is no goal per se, there is only which species survive and which do not. The authors interpret these differences in terms of intergenerational plasticity rather than as an evolutionary response. Movement Ecology Machine learning for modeling animal movement. Mov Ecol 8, 19 (2020). Movement Ecology Movement Ecology Movement Ecology It also includes options for re‐optimization based on random perturbations of the parameters to help explore the likelihood surface and diagnose convergence to local maxima. Whether or not we like it, in a capitalist economy social movement organizations require financial resources. Momentum is the single most valuable training you can go to to advance your understanding of how social movements build power to win. 8:33.

Above all, in order to use SME responsibly, practitioners must ground it in a vision of a common goal for the Movement, and an understanding of the liberatory values that connect activists and movements to the movement ecology. Movement ecology aims to provide common terminology and an integrative framework of movement research across all groups of organisms. Authors: J. The estimated wrapped Cauchy distribution for turning angle had mean angles (μt) biased towards the direction of ocean surface currents for each time step, with concentration parameter ρ = 0.86 (95% CI: 0.8–0.92) indicating turning angles were highly concentrated around μt.
