Menos raíces cerca de la superficie puede significar que las plantas absorben peor el agua y los nutrientes, algo que pesa en un ecosistema frágil como el del norte. Para quien sigue el manejo de la fauna silvestre y de los bosques, es una señal de que el impacto del pastoreo va más allá de lo que se ve. El estudio observó los cambios, pero no mide todavía cuánto afectan la salud de los bosques a largo plazo.","quienFirma":"Universidad de Finlandia (publicado en la revista Oikos)","confianza":"revisado","consulta":{"pregunta":"¿Deberían limitarse los renos en los bosques?"}},"sello":{"hash":"4778df05429f3e95bb65c651f697fa6febbc6e9cfb95872a37906676262b3e15","sello":"03dfe64ae19e6646b52a076d407f81adf4de0b79f4b4142f1d43fc27abcf2aa4","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6572330,"aleatorio":"5b1e47f2c14c8b70e08ce276355fba24926ab620c06e2c9381c6c4a1172ef6c7","tiempo":"2026-10-21T16:42:00.000Z"},"nist":{"cadena":2,"pulso":1993370,"salida":"27FA7F4029C2F763ACF2AAA6D66ED304EEDF4D8188928B568EF06C4D4E828D611A1794B647AD5762DCAA64E2A1ED33F95607FB6379F35741A18182E3BC32A55E","tiempo":"2026-10-21T16:41:00.000Z"},"noAntes":"2026-10-21T16:42:00.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 21 16:42:22 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"Reindeer grazing changes plant roots in pine forests","descripcion":"Reindeer grazing changes the vegetation of northern pine forests below ground as well as above it. In a recent study in Finland, trees and understory vegetation in grazed forests had nearly 30% less shallow-root biomass than those in ungrazed areas. Root structure also changed, which may affect the ability of plants to take up water and nutrients. The research is published in the journal Oikos.","pubDate":"Wed, 21 Oct 2026 12:40:09 EDT","url":"https://phys.org/news/2026-10-reindeer-grazing-roots-forests.html"},"indexado":"2026-10-21T16:41:55.298Z"}}
