Gemini man : the art and making of the movie
\"Two-time Academy Award-winner Ang Lee, the director of Life of Pi and Brokeback Mountain, brings his unique talents to Gemini man, an innovative action thriller that implements ground-breaking visual effects to deliver a unique and compelling story. Gemini man follows the elite but aging assassin Henry Brogan (Will Smith) who finds himself suddenly targeted by a mysterious young operative--one who knows his every move. Now the focus of an international manhunt, Brogan must confront his past, his choices, and himself if he plans to survive. Gemini man: the art and making of the movie offers exclusive concept art, interviews, and behind-the-scenes glimpses of this extraordinary film. Discover Brogan's journey from page to screen, including the progressive VFX and cinematic technology that made the film possible\"--Back cover

Lethal trap created by adaptive evolutionary response to an exotic resource
Global transport of organisms by humans provides novel resources to wild species, which often respond maladaptively. Native herbivorous insects have been killed feeding on toxic exotic plants, which acted as ‘ecological traps’

. We document a novel ‘eco-evolutionary trap’ stemming from the opposite effect; that is, high fitness on an exotic resource despite lack of adaptation to it.
Plantago lanceolata
was introduced to western North America by cattle-ranching. Feeding on this exotic plant released a large, isolated population of the native butterfly
Euphydryas editha
from a longstanding trade-off between maternal fecundity and offspring mortality. Because of this release—and despite a reduced insect developmental rate when feeding on this exotic—
Plantago
immediately supported higher larval survival than did the insects’ traditional host,
Collinsia parviflora
5
. Previous work from the 1980s documented an evolving preference for
Plantago
by ovipositing adults
6
. We predicted that if this trend continued the insects could endanger themselves, because the availability of
Plantago
to butterflies is controlled by humans, who change land management practices faster than butterflies evolve
6
. Here we report the fulfilment of this prediction. The butterflies abandoned
Collinsia
and evolved total dependence on
Plantago
. The trap was set. In 2005, humans withdrew their cattle, springing the trap. Grasses grew around the
Plantago
, cooling the thermophilic insects, which then went extinct. This local extinction could have been prevented if the population had retained partial use of
Collinsia
, which occupied drier microhabitats unaffected by cattle removal. The flush of grasses abated quickly, rendering the meadow once again suitable for
Euphydryas
feeding on either host, but no butterflies were observed from 2008 to 2012. In 2013–2014, the site was naturally recolonized by
Euphydryas
feeding exclusively on
Collinsia
, returning the system to its starting point and setting the stage for a repeat of the anthropogenic evolutionary cycle.
Local extinction of the butterfly
Euphydryas editha
occurred after the population was caught in an eco-evolutionary trap set when the insects evolved unanimous preference for an exotic host,
Plantago lanceolata
, and sprung when that host became embedded in grasses after humans removed cattle.

Human–nature connectedness as a pathway to sustainability: A global meta‐analysis
Internationally agreed sustainability goals are being missed. Here, we conduct global meta‐analyses to assess how the extent to which humans see themselves as part of nature—known as human–nature connectedness (HNC)—can be used as a leverage point to reach sustainability. A meta‐analysis of 147 correlational studies shows that individuals with high HNC had more pronature behaviours and were significantly healthier than those with low HNC. A meta‐analysis of 59 experimental studies shows significant increases in HNC after manipulations involving contact with nature and mindfulness practices. Surprisingly, this same meta‐analysis finds no significant effect of environmental education on HNC. Thus, HNC is positively linked to mind‐sets that value sustainability and behaviours that enhance it. Further, we argue that HNC can be enhanced by targeted practices, and we identify those most likely to succeed. Our results suggest that enhancing HNC, via promotion of targeted practices, can improve sustainability and should be integrated into conservation policy.

Phenological asynchrony between herbivorous insects and their hosts: signal of climate change or pre-existing adaptive strategy?
Climate change alters phenological relations between interacting species. We might expect the historical baseline, or starting-point, for such effects to be precise synchrony between the season at which a consumer most requires food and the time when its resources are most available. We synthesize evidence that synchrony was not the historical condition in two insect–plant interactions involving Edith's checkerspot butterfly (Euphydryas editha), the winter moth (Operophtera brumata) and their host plants. Initial observations of phenological mismatch in both systems were made prior to the onset of anthropogenically driven climate change. Neither species can detect the phenology of its host plants with precision. In both species, evolution of life history has involved compromise between maximizing fecundity and minimizing mortality, with the outcome being superficially maladaptive strategies in which many, or even most, individuals die of starvation through poor synchrony with their host plants. Where phenological asynchrony or mismatch with resources forms the starting point for effects of anthropogenic global warming, consumers are particularly vulnerable to impacts that exacerbate the mismatch. This vulnerability likely contributed to extinction of a well-studied metapopulation of Edith's checkerspot, and to the skewed geographical pattern of population extinctions underlying a northward and upward range shift in this species.

On the nature of the generating series of walks in the quarter plane
In the present paper, we introduce a new approach, relying on the Galois theory of difference equations, to study the nature of the generating series of walks in the quarter plane. Using this approach, we are not only able to recover many of the recent results about these series, but also to go beyond them. For instance, we give for the first time hypertranscendency results, i.e., we prove that certain of these generating series do not satisfy any nontrivial nonlinear algebraic differential equation with rational function coefficients.
