Open AccessWhat’s in a resource gradient? Comparing alternative cues for foraging in dynamic environments via movement, perception, and memory
Consumers must track and acquire resources in complex landscapes. Much discussion has focused on the concept of a ‘resource gradient’ and the mechanisms by which consumers can take advantage of such gradients ...

Article
Open AccessDiverse perspectives from diverse scholars are vital for theoretical biology
Science is based on studying some aspects of the world while holding others constant. The assumptions of what can and cannot be ignored implicitly shape our understanding of the world around us. This truth is ...

Open AccessThe regulating effect of growth plasticity on the dynamics of structured populations
Plasticity is the extent to which life history processes such as growth and reproduction depend on the environment. Plasticity in individual growth varies widely between taxa. Nonetheless, little is known abou...

Open AccessEffects of predator novelty on intraguild predation communities with adaptive prey defense
Understanding coexistence within community modules such as intraguild predation (IGP), where an omnivore both preys on and competes with an intermediate consumer for a shared resource, has provided insight int...

Article
Open AccessEvolutionary rescue can prevent rate-induced tip**
The transformation of ecosystems proceeds at unprecedented rates. Recent studies suggest that high rates of environmental change can cause rate-induced tip**. In ecological models, the associated rate-induced c...

Open AccessCoexistence patterns and diversity in a trait-based metacommunity on an environmental gradient
The dynamics of trait-based metacommunities have attracted much attention, but not much is known about how dispersal and spatial environmental variability mutually interact with each other to drive coexistence...

Article
Open AccessBe different to be better: the effect of personality on optimal foraging with incomplete knowledge
Many animal populations include a diversity of personalities, and these personalities are often linked to foraging strategy. However, it is not always clear why populations should evolve to have this diversity...

Open AccessThe effect of colonization dynamics in competition for space in metacommunities
One of the main factors that determines habitat suitability for sessile and territorial organisms is the presence or absence of another competing individual in that habitat. This type of competition arises in ...

Open AccessFire mitigates bark beetle outbreaks in serotinous forests
Bark beetle outbreaks and forest fires have imposed severe ecological damage and caused billions of dollars in lost resources in recent decades. The impact of such combined disturbances is projected to become ...

Article
Open AccessTransient disease dynamics across ecological scales
Analyses of transient dynamics are critical to understanding infectious disease transmission and persistence. Identifying and predicting transients across scales, from within-host to community-level patterns, ...

Article
Open AccessShould we account for mesozooplankton reproduction and ontogenetic growth in biogeochemical modeling?
Mesozooplankton play a key role in marine ecosystems as they modulate the transfer of energy from phytoplankton to large marine organisms. In addition, they directly influence the oceanic cycles of carbon and ...

Article
Open AccessSpatial heterogeneity of mortality and diffusion rates determines larval delivery to adult habitats for coastal marine populations
Many benthic animals begin life with a planktonic larval stage during which coastal currents may move individuals far from shore. This trait is believed to allow individuals to develop away from nearshore pred...

Article
Open AccessPatch isolation and periodic environmental disturbances have idiosyncratic effects on local and regional population variabilities in meta-food chains
While habitat loss is a known key driver of biodiversity decline, the impact of other landscape properties, such as patch isolation, is far less clear. When patch isolation is low, species may benefit from a ...

Article
Open AccessDelayed maturity does not offset negative impact afflicted by ectoparasitism in salmon
The negative effects of parasitism on host population dynamics may be mediated by plastic compensatory life-history changes in hosts. Theory predicts that hosts should shift their life-history towards early re...

Article
Open AccessApplying symmetries of elasticities in matrix population models
Elasticity analysis is a key tool in the analysis of matrix population models, which describe the dynamics of stage-structured populations in ecology and evolution. Elasticities of the dominant eigenvalue of a...

Article
Open AccessCoherence in (meta)community networks
In a general sense, a metacommunity can be considered as a network of communities, the coherence of which is based on characteristics that are shared by members of different communities, whatever forces were r...

Open AccessDynamics of a discrete-time pioneer–climax model
We present a simple mathematical model for the dynamics of a successional pioneer–climax system using difference equations. Each population is subject to inter- and intraspecific competition; population growth...

Article
Open AccessBiphasic range expansions with short- and long-distance dispersal
Long-distance dispersal (LDD) has long been recognized as a key factor in determining rates of spread in biological invasions. Two approaches for incorporating LDD in mathematical models of spread are mixed di...

Article
Open AccessRobustness of life histories to environmental variability in complex versus simple life cycles
Most animal species have a complex life cycle (CLC) with metamorphosis. It is thus of interest to examine possible benefits of such life histories. The prevailing view is that CLC represents an adaptation for ...

Open AccessEco-evolutionary dynamics may show an irreversible regime shift, illustrated by salmonids facing climate change
The enhanced or reduced growth of juvenile masu salmon (Oncorhynchus masou masou) may result from climate changes to their environment and thus impact on the eco-evolutionary dynamics of their life-history choice...
