Habitat adequado \u00e9 muitas vezes limitado e compartilhado por v\u00e1rios indiv\u00edduos de muitas esp\u00e9cies. \u00c9 somente por meio da diversifica\u00e7\u00e3o que todos conseguem sobreviver: utilizando diferentes maneiras de obter diferentes presas em diferentes micro-habitats. Al\u00e9m disso, as exig\u00eancias das aves lim\u00edcolas mudam ao longo de seu extraordin\u00e1rio ciclo de vida – o que os ma\u00e7aricos-de-papo-vermelho (Calidris canutus<\/em>) exigem nos locais de reprodu\u00e7\u00e3o no \u00c1rtico n\u00e3o \u00e9 necessariamente o que eles precisam nos locais de invernada no Chile. As aves s\u00e3o equipadas com as ferramentas certas no momento certo para seu uso espec\u00edfico, assim como um encanador precisa de um alicate, mas um carpinteiro precisa de uma chave de fenda.[\/vc_column_text][vc_column_text margin_bottom=”20″ css=”.vc_custom_1684956917277{margin-top: 0px !important;margin-bottom: 0px !important;padding-top: 0px !important;}”]\n

A vers\u00e3o curta e a longa<\/h4>\n[\/vc_column_text][vc_column_text margin_bottom=”20″ css=”.vc_custom_1684954933296{margin-top: 0px !important;margin-bottom: 0px !important;padding-top: 0px !important;}”]Quanto mais longas forem suas pernas, mais fundo elas podem ir. As aves lim\u00edcolas costumam habitar a zona lim\u00edtrofe e intermitente entre o \u00famido e o seco. Para usar esse habitat din\u00e2mico e vari\u00e1vel, essas aves t\u00eam pernas longas em compara\u00e7\u00e3o com a maioria dos outros grupos, assim elas podem usar habitats aqu\u00e1ticos para se alimentar sem molhar as penas. Essas varia\u00e7\u00f5es no comprimento das pernas das aves lim\u00edcolas fazem com que as diferentes esp\u00e9cies se espalhem pelas \u00e1reas \u00famidas, campos e litorais, evitando a competi\u00e7\u00e3o.[\/vc_column_text][\/vc_column][\/vc_row][mk_page_section min_height=”1″ padding_bottom=”0″ sidebar=”sidebar-1″][vc_column width=”1\/6″][\/vc_column][vc_column width=”2\/3″][mk_image src=”https:\/\/whsrn.org\/wp-content\/uploads\/2023\/05\/portugues_ok_03.jpg” image_size=”full”][\/vc_column][vc_column width=”1\/6″][\/vc_column][\/mk_page_section][vc_row][vc_column][mk_padding_divider size=”20″][vc_column_text margin_bottom=”20″ css=”.vc_custom_1684955066409{margin-top: 0px !important;margin-bottom: 0px !important;padding-top: 0px !important;}”]\n

Os bicos das aves lim\u00edcolas fornecem evid\u00eancias ainda mais convincentes da evolu\u00e7\u00e3o das adapta\u00e7\u00f5es e determinam onde, como e do que elas se alimentam. De fato, quanto mais longo for o bico de uma ave lim\u00edcola, mais fundo ela procurar\u00e1 por vermes; isso significa que o ma\u00e7arico-de-asa-branca (Tringa semipalmata<\/em>) pode se alimentar ao lado do ma\u00e7arico-de-bico-virado (Limosa haemastica<\/em>) sem competi\u00e7\u00e3o, pois o \u00faltimo tem um bico muito mais longo. Os ma\u00e7aricos (Calidris sp.<\/em>) normalmente t\u00eam um bico mais longo e estreito, o que lhes permite pegar anf\u00edpodes na superf\u00edcie da \u00e1gua e sondar a lama em diferentes profundidades em busca de vermes.<\/p>\n

N\u00e3o \u00e9 apenas o comprimento do bico que conta, mas tamb\u00e9m o formato. Os bicos retos conferem for\u00e7a, permitindo que as aves lim\u00edcolas maiores, como os ma\u00e7aricos-de-costas-brancas (Limnodromus griseus<\/em>), sondem o solo firme. Os bicos curvos oferecem ajuda diferente e variada. Algumas tamb\u00e9m se beneficiam de uma peculiaridade morfol\u00f3gica inesperada: o bico do ma\u00e7arico-de-papo-vermelho (Calidris canutus<\/em>) pode parecer r\u00edgido e duro, mas na verdade \u00e9 um “bico flex\u00edvel”, com uma ponta male\u00e1vel que se abre apenas o suficiente para agarrar a presa sem ser inundado por \u00e1gua lamacenta.<\/p>\n<\/div>\n<\/div>\n[\/vc_column_text][\/vc_column][\/vc_row][mk_page_section min_height=”1″ padding_bottom=”0″ sidebar=”sidebar-1″][vc_column width=”1\/6″][\/vc_column][vc_column width=”2\/3″][mk_image src=”https:\/\/whsrn.org\/wp-content\/uploads\/2023\/05\/portugues_ok_04.jpg” image_size=”full”][\/vc_column][vc_column width=”1\/6″][\/vc_column][\/mk_page_section][vc_row][vc_column][vc_column_text margin_bottom=”20″ css=”.vc_custom_1685111582117{margin-bottom: 0px !important;}”]\n

  • Os bicos curvos oferecem estrat\u00e9gias diferentes de alimenta\u00e7\u00e3o. O bico curvado para baixo do ma\u00e7arico-galego (Numenius phaeopus<\/em>) \u00e9 um verdadeiro canivete su\u00ed\u00e7o. A curvatura facilita o acesso \u00e0s tocas arqueadas dos caranguejos Uca (conhecidos tamb\u00e9m como chama-mar\u00e9), mas tamb\u00e9m oferece uma grande “\u00e1rea de contato” com a presa e facilita a pegada.<\/li>\n
  • O piru-piru usa seu bico grosso e achatado como alavanca para abrir moluscos bivalves ou martel\u00e1-los contra rochas.<\/li>\n
  • O bico curvado para cima de lim\u00edcolas como o de Recurvirostra andina<\/em> traz ainda outra especializa\u00e7\u00e3o. Ao mover o bico de um lado para o outro embaixo d’\u00e1gua, a ave filtra as presas que est\u00e3o na \u00e1gua atrav\u00e9s de lamelas, estruturas semelhantes \u00e0 pelos – vers\u00f5es min\u00fasculas das barbatanas das baleias rorquais.<\/li>\n
  • O bico em forma de cinzel do vira-pedras (Arenaria interpres<\/em>) o ajuda a procurar alimento embaixo de algas marinhas e at\u00e9 mesmo a\u2026 virar pedras grandes.<\/li>\n
  • Os bicos curtos e atarracados das batu\u00edras s\u00e3o adaptados para que pegar, bicar e arrancar presas da areia na praia, da lama ou das rochas.<\/li>\n<\/ul>\n<\/div>\n[\/vc_column_text][mk_padding_divider size=”20″][vc_column_text margin_bottom=”20″ css=”.vc_custom_1684955620108{margin-top: 0px !important;margin-bottom: 0px !important;padding-top: 0px !important;}”]\n

    O ecologista Theunis Piersma descobriu que o ma\u00e7arico-de-papo-vermelho (Calidris canutus)<\/em>, o Calidris alpina<\/em>, o ma\u00e7ariquinho (Calidris minutilla<\/em>) e outras aves que sondam a linha costeira conseguem detectar “gradientes de press\u00e3o” causados por presas enterradas na lama. Piersma revelou que o v\u00e3o oco da ponta do bico das aves lim\u00edcolas cont\u00e9m “po\u00e7os sensoriais” repletos de termina\u00e7\u00f5es nervosas chamados “corp\u00fasculos de Herbst”. Esses corp\u00fasculos permitem que uma ave “veja” ao mergulhar o bico dentro da \u00e1gua turva: os ma\u00e7aricos-brancos (Calidris alba<\/em>)\u00a0 podem detectar vermes a at\u00e9 2 cm de dist\u00e2ncia – quase o comprimento total do bico.<\/p>\n<\/div>\n[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][mk_padding_divider size=”20″][vc_column_text margin_bottom=”20″ css=”.vc_custom_1684955652932{margin-top: 0px !important;margin-bottom: 0px !important;padding-top: 0px !important;}”]\n

    Para detectar presas min\u00fasculas a uma grande dist\u00e2ncia – v\u00e1rias vezes o comprimento do seu corpo – as batu\u00edras precisam de uma vis\u00e3o apurada o que explica os olhos notoriamente grandes.<\/p>\n<\/div>\n[\/vc_column_text][\/vc_column][\/vc_row][mk_page_section min_height=”1″ padding_bottom=”0″ sidebar=”sidebar-1″][vc_column width=”1\/6″][\/vc_column][vc_column width=”2\/3″][mk_image src=”https:\/\/whsrn.org\/wp-content\/uploads\/2023\/05\/portugues_ok_05.jpg” image_size=”full”][\/vc_column][vc_column width=”1\/6″][\/vc_column][\/mk_page_section][vc_row][vc_column][mk_padding_divider size=”20″][vc_column_text margin_bottom=”20″ css=”.vc_custom_1684955837372{margin-top: 0px !important;margin-bottom: 0px !important;padding-top: 0px !important;}”]\n

    Muito sal<\/h4>\n[\/vc_column_text][vc_column_text margin_bottom=”20″ css=”.vc_custom_1684956261564{margin-bottom: 0px !important;}”]\n
    \n

    A ingest\u00e3o de sal, seja por meio de presas marinhas ou da \u00e1gua do mar, poderia causar a desidrata\u00e7\u00e3o de uma ave. No geral, as aves n\u00e3o possuem mecanismos para lidar com essa situa\u00e7\u00e3o, mas as aves lim\u00edcolas possuem. Sua principal adapta\u00e7\u00e3o s\u00e3o as gl\u00e2ndulas de sal, que drenam o excesso de sal da corrente sangu\u00ednea de uma ave lim\u00edcola. O tamanho das gl\u00e2ndulas depende do quanto elas ser\u00e3o usadas. O tamanho das gl\u00e2ndulas tamb\u00e9m pode variar sazonalmente. Na esta\u00e7\u00e3o n\u00e3o reprodutiva, o ma\u00e7arico-de-papo-vermelho (Calidris canutus<\/em>) tem gl\u00e2ndulas muito grandes porque sempre ingere \u00e1gua salgada ao engolir bivalves nas praias. No entanto, enquanto fazem ninhos no interior do continente suas gl\u00e2ndulas diminuem pois n\u00e3o ingerem \u00e1gua salgada ao se alimentar.<\/p>\n<\/div>\n[\/vc_column_text][\/vc_column][\/vc_row][mk_page_section full_width=”true” padding_top=”25″ padding_bottom=”0″ sidebar=”sidebar-1″][vc_column width=”1\/2″ css=”.vc_custom_1536683611141{margin-right: 0px !important;margin-left: 0px !important;padding-right: 3px !important;padding-left: 3px !important;}”][mk_image src=”https:\/\/whsrn.org\/wp-content\/uploads\/2023\/05\/unique_4.jpg” image_size=”full”][\/vc_column][vc_column width=”1\/2″ css=”.vc_custom_1536683620659{margin-right: 0px !important;margin-left: 0px !important;padding-right: 3px !important;padding-left: 3px !important;}”][mk_image src=”https:\/\/whsrn.org\/wp-content\/uploads\/2023\/05\/unique_6.jpg” image_size=”full”][\/vc_column][\/mk_page_section][vc_row][vc_column][mk_fancy_title tag_name=”span” color=”#53565a” size=”12″ font_weight=”bold” margin_bottom=”0″ font_family=”none” align=”center”]\n

    De todas as aves lim\u00edcolas, nenhuma \u00e9 mais ligada ao sal do que os pisa-n\u2019\u00e1gua. Os pisa-n’\u00e1gua-de-pesco\u00e7o-vermelho (Phalaropus lobatus<\/em>) podem passar nove meses por ano no mar, enquanto os pisa-n’\u00e1gua-de-bico-grosso (P. fulicarius<\/em>) podem passar onze. At\u00e9 mesmo o pisa-d’\u00e1gua (P. tricolor<\/em>), que vive no interior do continente, utiliza lagos salgados como s\u00edtio de parada e alimenta\u00e7\u00e3o ao longo da rota migrat\u00f3ria e como s\u00edtio n\u00e3o-reprodutivo. O especialista em aves lim\u00edcolas Joseph Jehl ficou surpreso ao constatar que o pisa-n\u2019\u00e1gua n\u00e3o acumula sal no corpo, ainda mais ao descobrir que isso n\u00e3o se devia ao uso de gl\u00e2ndulas de sal, cujo tamanho relativo n\u00e3o era maior do que o de outras aves lim\u00edcolas. Jehl descobriu que os pisa-n\u2019\u00e1gua usam a tens\u00e3o superficial da \u00e1gua salgada, que sobe pelo bico quando eles se alimentam, para espirra a \u00e1gua salgada para fora antes de engolir a presa.<\/p>\n<\/div>\n[\/vc_column_text][\/vc_column][\/vc_row][mk_page_section full_width=”true” padding_top=”25″ padding_bottom=”0″ sidebar=”sidebar-1″][vc_column width=”1\/2″ css=”.vc_custom_1536683611141{margin-right: 0px !important;margin-left: 0px !important;padding-right: 3px !important;padding-left: 3px !important;}”][mk_image src=”https:\/\/whsrn.org\/wp-content\/uploads\/2023\/05\/unique_1.jpg” image_size=”full”][\/vc_column][vc_column width=”1\/2″ css=”.vc_custom_1536683620659{margin-right: 0px !important;margin-left: 0px !important;padding-right: 3px !important;padding-left: 3px !important;}”][mk_image src=”https:\/\/whsrn.org\/wp-content\/uploads\/2023\/05\/unique_5.jpg” image_size=”full”][\/vc_column][\/mk_page_section][vc_row][vc_column][mk_fancy_title tag_name=”span” color=”#53565a” size=”12″ font_weight=”bold” margin_bottom=”0″ font_family=”none” align=”center”]\n

    Sem d\u00favida, o truque mais elaborado das aves lim\u00edcolas migrat\u00f3rias \u00e9 a capacidade que algumas esp\u00e9cies t\u00eam de encolher \u00f3rg\u00e3os do corpo, dando espa\u00e7o para m\u00fasculos e reservas de gordura necess\u00e1rios a suas longas viagens. Sabe-se que tanto o pisa-n\u2019\u00e1gua quanto o ma\u00e7arico-rasteirinho dobram de peso rapidamente antes de migrar (de fato, alguns pisa-d\u2019\u00e1gua examinados por Joseph Jehl ficaram temporariamente gordos demais para voar)! Estudos com ma\u00e7aricos-de-papo-vermelho durante a migra\u00e7\u00e3o mostraram que, \u00e0 medida que o peso total aumentava, o mesmo acontecia com os m\u00fasculos peitorais e card\u00edacos – mas isso era compensado pelo encolhimento dos intestinos, f\u00edgado, moela, est\u00f4mago e m\u00fasculo da perna. Assim, conseguiam reduzir a carga carregada durante o voo. Ao chegarem aos locais de reprodu\u00e7\u00e3o, depois de finalizada a migra\u00e7\u00e3o, os tamanhos dos \u00f3rg\u00e3os voltavam ao normal.<\/p>\n<\/div>\n[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][mk_fancy_title tag_name=”span” color=”#3d4045″ size=”12″ font_weight=”400″ font_family=”none”]Foto de capa: Aves lim\u00edcolas com pernas e bicos de diferentes tamanhos e formas podem compartilhar um mesmo habitat sem competir por presas.
