Ecology of reintroduced Rocky Mountain bighorn sheep in Dinosaur National Monument La Ecología de Borrego Cimarron de las Montañas Rocosas Reintroducido en el Monumento Nacional de Dinosaurio

Wildlife Monographs, Volume 223, Issue 1, August 2026.
We synthesized GPS telemetry, genetic, and pathogen data to evaluate metapopulation processes in a reintroduced Rocky Mountain bighorn sheep (Ovis canadensis canadensis) population in Dinosaur National Monument. We estimated subpopulation‐specific abundances and found 4 small subpopulations with high genetic diversity, partial connectivity, and ...

Stability and bifurcation analysis in a predator prey model involving additive Allee effect

Revista Integración
In this paper we study codimension 1 Hopf bifurcation for a two dimensional autonomous nonlinear ordinary differential equations system, modeling a predator-prey interaction with Holling type II functional response and additive Allee effect in the prey ...

Evaluating potential restoration strategies for vascular epiphytes with niche‐based community mechanistic models

Journal of Applied Ecology, Volume 63, Issue 8, August 2026.
Generally, delayed restoration of adult‐only epiphyte populations into older restored forests improves conservation outcomes. However, restoration can be optimised, initially introducing large populations of fast‐growing, light‐when‐mature species in younger forests followed by the later introduction of slow‐growing, heavy‐when‐mature species in ...

Analytical classification of dispersal effects on total biomass in the presence of a weak Allee effect

Biomath
We investigate the impact of the weak Allee effect on the total biomass of a single species inhabiting a two-patch environment connected by asymmetric dispersal.

Inferring alternative ecosystem states with field survey data

Methods in Ecology and Evolution, Volume 17, Issue 8, Page 2256-2276, August 2026.
Abstract Many ecosystems potentially exhibit alternative stable states, where distinct states can coexist under identical environmental conditions. While simulation models have generated key hypotheses in alternative stable states theory, they often rely on scale‐free parameters disconnected from real ecosystems.

Quantifying Colonisation Pressure as a Driver of Secondary Spread During the Dreissena polymorpha Invasion of German River Networks

Freshwater Biology, Volume 71, Issue 8, August 2026.
ABSTRACT Biological invasions have become a major component of global change, yet the processes governing secondary spread after initial introductions remain insufficiently resolved. A specific and central gap is the lack of a spatially explicit and temporally dynamic quantification of colonisation pressure, despite its presumed importance for ...

Firm‐Level Political Risk and Earnings Manipulation

Journal of Business Finance &Accounting, Volume 53, Issue 4, Page 1382-1408, August 2026.
ABSTRACT Using recently developed proxies for firm‐level political risk and earnings manipulation, we test the limited attention theory. Contrary to Hirshleifer and Teoh's core prediction that investor attention is associated with less managerial manipulation, we find that firm‐level political risk, serving as a proxy for investor attention, is ...
