Food Subsidy Effects on Host Foraging Behavior Shape Host–Macroparasite Infection Dynamics

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
Wildlife behavioral responses to different distributions of food subsidies could shape encounter and infection intensity of environmentally transmitted parasites. Using a mathematical model, we show that the way in which food subsidy changes transmission rate and variation in parasite burdens (e.g., through changes in time spent foraging and variation ...

Circular 59 [PDF]

open access: yes, 1987
This list of recommended annual flower varieties includes information on several hundred annual flower cultivars. The recommended varieties were selected from flowers grown in 1985 and 1986 at the Agricultural and Forestry Experiment Station Farm ...

Consequences of toxic secondary compounds in nectar for mutualist bees and antagonist butterflies [PDF]

open access: yes, 2016
Attraction of mutualists and defense against antagonists are critical challenges for most organisms and can be especially acute for plants with pollinating and non?pollinating flower visitors.

Returning neighbors: eastern wild turkey (Meleagris gallopavo silvestris) occupancy in an urban landscape

open access: yesThe Journal of Wildlife Management, Volume 90, Issue 1, January 2026.
We found that urban wild turkey had a higher probability of occupying a site if it was farther from roads and trails, closer to water, had more available habitat at finer spatial scales, or had lower mean tree height at larger spatial scales Abstract Once extirpated from most of its range because of overharvest and habitat loss in the early 1900s, the ...

Reduction in common milkweed (Asclepias syriaca) occurrence in Iowa cropland from 1999 to 2009 [PDF]

open access: yes, 2010
The role of common milkweed in the lifecycle of the monarch butterfly has increased interest in the presence of this weed in the north central United States.

Mixed-Species Gardens Increase Monarch Oviposition without Increasing Top-Down Predation

open access: yesInsects, 2020
Monarch butterfly populations have declined by over 80% in the last 20 years. Conservation efforts focus on the creation of milkweed habitats to mitigate this decline.

A Spectral‐Spatial Dual Encoder With Bio‐Inspired Swarm Adaptation for Cognitive Spectrum Sensing Using Real‐World RF Signal Data

open access: yesIET Communications, Volume 20, Issue 1, January/December 2026.
The proposed model includes a dual‐stream deep learning architecture which has a 1D convolutional neural network (CNN)‐based spectral encoder and a graph convolutional network (GCN)‐based spatial encoder for extracting the frequency‐domain and node‐topology features. Experimental analysis of the proposed model is performed using the Real‐World Wireless

Wetland location and captive breeding influence trans‐Mediterranean movements in the endangered Marbled Duck (Marmaronetta angustirostris)

open access: yesIbis, Volume 168, Issue 1, Page 245-258, January 2026.
Waterbirds distributed in semi‐arid and arid regions seem to have adapted their behaviour to the availability and seasonality of wetlands, increasing their mobility range. The Marbled Duck Marmaronetta angustirostris is a threatened waterbird that shows trans‐Mediterranean movements but these are poorly known.

Hierarchy-based Image Embeddings for Semantic Image Retrieval

open access: yes, 2019
Deep neural networks trained for classification have been found to learn powerful image representations, which are also often used for other tasks such as comparing images w.r.t. their visual similarity. However, visual similarity does not imply semantic
