Spatial scales of interactions among bacteria and between bacteria and the leaf surface. [PDF]

, 2015
Microbial life on plant leaves is characterized by a multitude of interactions between leaf colonizers and their environment. While the existence of many of these interactions has been confirmed, their spatial scale or reach often remained unknown.

House Sparrows Passer domesticus increase in body size and dorsal feather insulation along a Himalayan elevational gradient

Journal of Field Ornithology
Elevational gradients impact organisms in diverse ways because of lower temperatures and oxygen levels at higher elevations. Birds adapt to these constraints through changes in body size, plumage, metabolism, and behaviors such as elevational migration ...

Estimating above ground net biomass change in tropical and subtropical forests: refinement of IPCC default values using forest plot data [PDF]

, 2019
As countries advance in greenhouse gas (GHG) accounting for climate change mitigation, consistent estimates of above ground biomass (AGB) net change are needed for the tropics and subtropics.

Awakened oscillations in coupled consumer-resource pairs [PDF]

, 2014
The paper concerns two interacting consumer-resource pairs based on chemostat-like equations under the assumption that the dynamics of the resource is considerably slower than that of the consumer.

The Role of Crop, Livestock, and Farmed Aquatic Intraspecific Diversity in Maintaining Ecosystem Services

Diversity
Most of the attention given to intraspecific crop, livestock, and aquaculture diversity in agricultural production systems has been targeted at their roles in providing provisioning services, such as food and fibre or their cultural services, providing ...

Complex dynamics in coevolution models with ratio-dependent functional response

, 2009
We explore the complex dynamical behavior of two simple predator-prey models of biological coevolution that on the ecological level account for interspecific and intraspecific competition, as well as adaptive foraging behavior.

Endogenous and exogenous constraints in the population changes of wild boar (sus scrofa Linnaeus, 1758) [PDF]

, 2004
The population dynamics of wild boar (Sus scrofa) was studied in a time series over 26 years using data from the Regional Hunting Reserve of Somiedo (northern Spain).

Survival of the Scarcer in Space

, 2013
The dynamics leading to extinction or coexistence of competing species is of great interest in ecology and related fields. Recently a model of intra- and interspecific competition between two species was proposed by Gabel et al. [Phys. Rev.

Road mitigation is a demographic filter for grizzly bears

Wildlife Society Bulletin, 2017
Crossing structures (i.e., underpasses and overpasses) are becoming a widespread approach to promote movement of wildlife across roads. Studies have shown that species select for different crossing structure designs, yet little is known about ...
