Sensitivity of Vegetation Indices for Estimating Vegetative N Status in Winter Wheat

Sensors, 2019
Precise sensor-based non-destructive estimation of crop nitrogen (N) status is essential for low-cost, objective optimization of N fertilization, as well as for early estimation of yield potential and N use efficiency.

Electric Eels Wield a Functional Venom Analogue

Toxins, 2021
In this paper, I draw an analogy between the use of electricity by electric eels (Electrophorus electricus) to paralyze prey muscles and the use of venoms that paralyze prey by disrupting the neuromuscular junction.

Tearing Out the Income Tax by the (Grass)Roots [PDF]

, 2011
Landscapes are increasingly fragmented, and conservation programs have started to look at network approaches for maintaining populations at a larger scale. We present an agent-based model of predator–prey dynamics where the agents (i.e.

Do Striped Hyenas Have a Sweet Tooth? First Evidence of Honey Consumption by a Hyaenid

Ecology and Evolution
Dietary flexibility in carnivores remains an underexplored aspect of their ecology, particularly the consumption of non‐meat foods. While striped hyenas (Hyaena hyaena) are primarily scavengers, they are known to occasionally consume plant material ...

Temporal and Spectral Optimization of Vegetation Indices for Estimating Grain Nitrogen Uptake and Late-Seasonal Nitrogen Traits in Wheat

Sensors, 2019
Grain nitrogen (N) uptake (GNup) in winter wheat (Triticum aestivum L.) is influenced by multiple components at the plant organ level and by pre- and post-flowering N uptake (Nup). Although spectral proximal high-throughput sensing is promising for field

Ethology and Overwintering of \u3ci\u3ePodalonia Luctuosa\u3c/i\u3e (Hymenoptera: Sphecidae) [PDF]

, 2017
The nesting and overwintering behavior of Podalonia luctuosa (Smith) was studied in New York and Colorado. Females provisioned shallow (ca. 2 cm deep), unicellular nests with a single cutworm (Noctuidae) during April, May, and July.
