Object manipulation without hands

S Sugasawa, B Webb… - Proceedings of the …, 2021 - royalsocietypublishing.org
Our current understanding of manipulation is based on primate hands, resulting in a detailed
but narrow perspective of ways to handle objects. Although most other animals lack hands …

Chemical differences between seeds and elaiosomes indicate an adaptation to nutritional needs of ants

RC Fischer, A Richter, F Hadacek, V Mayer - Oecologia, 2008 - Springer
Ant-dispersed plants usually produce seeds with appendages (elaiosomes) as reward for
ants. Plants that produce high-quality elaiosomes benefit because ants preferentially …

Response of ants and their seed removal in rehabilitation areas and forests at El Cerrejon coal mine in Colombia

Y Dominguez‐Haydar, I Armbrecht - Restoration Ecology, 2011 - Wiley Online Library
Open‐pit coal mining causes strong negative impacts on biodiversity because this activity
completely removes thick layers of soil. Focusing on ants as functional agents responding to …

Savanna fires increase rates and distances of seed dispersal by ants

CL Parr, AN Andersen, C Chastagnol, C Duffaud - Oecologia, 2007 - Springer
Myrmecochory (seed dispersal by ants) is a prominent dispersal mechanism in many
environments, and can play a key role in local vegetation dynamics. Here we investigate its …

Are tortoises important seed dispersers in Amazonian forests?

A Jerozolimski, MBN Ribeiro, M Martins - Oecologia, 2009 - Springer
According to most studies on seed dispersal in tropical forests, mammals and birds are
considered the main dispersal agents and the role played by other animal groups remains …

Myrmecochorous plants use chemical mimicry to cheat seed‐dispersing ants

M Pfeiffer, H Huttenlocher, M Ayasse - Functional Ecology, 2010 - Wiley Online Library
Deceptive species are a characteristic trait of insect–plant mutualisms. Deception of
pollinators is essential for reproduction in diverse plant species; however, mimicry in seed …

Ant tunneling—a granular media perspective

DN Espinoza, JC Santamarina - Granular Matter, 2010 - Springer
Laboratory and field data show that the digging habits of ants and the resulting nest
architecture vary with soil conditions, yet, the geomechanical understanding of ant tunneling …

Redispersal of seeds by a keystone ant augments the spread of common wildflowers

JE Canner, RR Dunn, I Giladi, K Gross - Acta oecologica, 2012 - Elsevier
Myrmecochory (dispersal of seeds by ants) is an evolutionarily and ecologically common
mutualism. Most of the research on the costs and benefits of myrmecochory in North America …

Ant-seed interactions: combined effects of ant and plant species on seed removal patterns

P Servigne, C Detrain - Insectes Sociaux, 2008 - Springer
Seed dispersal by ants (ie myrmecochory) is usually considered as a mutualism: ants feed
on nutritive bodies, called elaiosomes, before rejecting and dispersing seeds in their nest …

Competition as a mechanism structuring mutualisms

RJ Warren, I Giladi, MA Bradford - Journal of Ecology, 2014 - Wiley Online Library
Hutchinsonian niche theory posits that organisms have fundamental abiotic resource
requirements from which they are limited by competition. Organisms also have fundamental …
