Relational knowing as method and practice

People and Nature, EarlyView.
Abstract This paper seeks to contribute to (re)building the capacity for embodied, place‐based relational knowing, transforming how we know and thus what we know. What is known, or sought to be known, is relations. How we know these relations is by already being in it: breathing, sensing, moving, listening, responding, affecting and being affected ...

Representation of Thermal Information in the Antennal Lobe of Leaf-Cutting Ants [PDF]

Frontiers in Behavioral Neuroscience, 2010
Insects are equipped with various types of antennal sensilla, which house thermosensitive neurons adapted to receive different parameters of the thermal environment for a variety of temperature-guided behaviors. In the leaf-cutting ant Atta vollenweideri, the physiology and the morphology of the thermosensitive sensillum coeloconicum (Sc) has been ...

Quantificação das perdas no desenvolvimento de Pinus taeda após o ataque de formigas cortadeiras

Ciência Florestal, 2008
In this study, the main purpose was to quantify the diameter, height and productivity index losses in initial development in Pinus taeda seedlings in stands in Argentine, after leaf cutting ants attack. The treatments were: T1 = control without attack;

Ethnobotanical and genetic assessments of Central American avocado landraces reveal novel sources of biodiversity and ancient migration patterns

PLANTS, PEOPLE, PLANET, EarlyView.
Avocados are a multibillion‐dollar global commodity, but their growing export market pressures local farmers to abandon local fruit tree diversity in favor of commercial cultivar production. Interviews with rural avocado farmers and households from the Southern Mexican Highlands, Pacific Coastal Honduras, and Western Nicaragua, as well as the genetic ...

An extinction‐emergency metacollection: Maximising future recovery options for Rhodomyrtus psidioides (Myrtaceae), threatened by Myrtle Rust

PLANTS, PEOPLE, PLANET, EarlyView.
A challenge for wild plant conservation is the rising incidence of plant pathogens that are difficult to interdict, contain and manage. Invasive, fast‐moving, broad‐spectrum pathogens impose societal costs through losses of intrinsically valuable wild biodiversity, ecosystem function, current and potential genetic and biological assets, culturally ...

Occurrence of polygyny in Acromyrmex subterraneus molestans Santschi 1925 (Hymenoptera: Formicidae) [PDF]

Ciência Rural, 2004
Polygyny denotes the coexistence of two or more mated and fertile queens in the colony. A colony of Acromyrmex subterraneus molestans Santschi containing 14 queens was collected on campus of the Universidade Federal de Viçosa, Brazil, aiming to verify if

Strong differentiation between source and ex situ populations of rare plant species revealed by next‐generation sequencing

PLANTS, PEOPLE, PLANET, EarlyView.
Biodiversity is being lost rapidly worldwide due to factors such as climate change and habitat loss. To help safeguard plant populations, conservation strategies include seed banks and conservation cultures. However, it remains unclear how cultivation affects genetic variation compared with wild populations.

Parasitism, sexual dimorphism and effect of host size on Apocephalus attophilus offspring, a parasitoid of the leaf-cutting ant Atta bisphaerica.

PLoS ONE, 2018
Atta bisphaerica (Forel) is a leaf-cutting ant that specializes on grass and causes productivity losses in sugar cane fields and pastures. Three phorid species, Apocephalus attophilus (Borgmeier), Myrmosicarius grandicornis (Borgmeier) and ...

Phorid Flies Parasitizing Leaf-Cutting Ants: Their Occurrence, Parasitism Rates, Biology and the First Account of Multiparasitism

Sociobiology, 2016
The leaf-cutting ants Atta sexdens (Linnaeus) and Atta laevigata (Smith) were parasitized by the following phorid flies: Apocephalus attophilus Borgmeier, Apocephalus vicosae Disney, Myrmosicarius grandicornis Borgmeier and species of Eibesfeldtphora ...

Mortality in an invasive ant does not scale linearly with fipronil exposure

Pest Management Science, EarlyView.
Increasing fipronil concentration did not linearly increase yellow crazy ant mortality when introduced via horizontal transfer; high doses may limit food sharing. Queen mortality was low, and surviving workers were averse to feeding. Abstract Background Controlling eusocial invasive and other pestiferous insects is difficult.
