Home range and habitat use by Kemp's Ridley turtles in West-Central Florida [PDF]

, 2003
The Kemp's ridley turtle (Lepidochelys kempii) is an endangered species whose recovery depends in part on the identification and protection of required habitats.

Complementarity in nutrient foraging strategies of absorptive fine roots and arbuscular mycorrhizal fungi across 14 coexisting subtropical tree species.

New Phytologist, 2015
In most cases, both roots and mycorrhizal fungi are needed for plant nutrient foraging. Frequently, the colonization of roots by arbuscular mycorrhizal (AM) fungi seems to be greater in species with thick and sparsely branched roots than in species with ...

Stochastic dynamics of social patch foraging decisions [PDF]

arXiv, 2022
Animals typically forage in groups. Social foraging can help animals avoid predation and decrease their uncertainty about the richness of food resources. Despite this, theoretical mechanistic models of patch foraging have overwhelmingly focused on the behavior of single foragers.

lrSVD: An efficient imputation algorithm for incomplete high‐throughput compositional data

Journal of Chemometrics, Volume 36, Issue 12, December 2022., 2022
Abstract Compositional methods have been successfully integrated into the chemometric toolkit to analyse and model different types of data generated by modern high‐throughput technologies. Within this compositional framework, the focus is put on the relative information conveyed in the data by using log‐ratio coordinate representations.

Are white storks addicted to junk food? Impacts of landfill use on the movement and behaviour of resident white storks (Ciconia ciconia) from a partially migratory population [PDF]

, 2016
Background: The migratory patterns of animals are changing in response to global environmental change with many species forming resident populations in areas where they were once migratory. The white stork (Ciconia ciconia) was wholly migratory in Europe

Adaptive patch foraging in deep reinforcement learning agents [PDF]

arXiv, 2022
Patch foraging is one of the most heavily studied behavioral optimization challenges in biology. However, despite its importance to biological intelligence, this behavioral optimization problem is understudied in artificial intelligence research. Patch foraging is especially amenable to study given that it has a known optimal solution, which may be ...

Impact of controlled neonicotinoid exposure on bumblebees in a realistic field setting [PDF]

, 2016
1. Pesticide exposure has been implicated as a contributor to insect pollinator declines. In social bees, which are crucial pollination service providers, the effect of low-level chronic exposure is typically non-lethal leading researchers to consider ...

Urban Foraging: A Ubiquitous Human Practice Overlooked by Urban Planners, Policy, and Research

, 2017
Although hardly noticed or formally recognised, urban foraging by humans probably occurs in all urban settings around the world. We draw from research in India, South Africa, Sweden, and the United States to demonstrate the ubiquity and varied nature of ...

Urban gardens promote bee foraging over natural habitats and plantations

Ecology and Evolution, 2016
Increasing human land use for agriculture and housing leads to the loss of natural habitat and to widespread declines in wild bees. Bee foraging dynamics and fitness depend on the availability of resources in the surrounding landscape, but how precisely ...

Functional diversity of farmland bees across rural–urban landscapes in a tropical megacity

Ecological Applications, Volume 32, Issue 8, December 2022., 2022
Abstract Urbanization poses a major threat to biodiversity and food security, as expanding cities, especially in the Global South, increasingly compete with natural and agricultural lands. However, the impact of urban expansion on agricultural biodiversity in tropical regions is overlooked.
