Actualización de la distribución de Boeckella gracilis (Daday, 1902) (Crustacea, Copepoda) en la Región de la Araucanía (38°s), Chile, y un modelo nulo para comprender sus asociaciones específicas en su hábitat [PDF]

open access: yes, 2012
The crustacean zooplankton of Chilean inland waters are characterized by abundant calanoid copepods, mainly from the genus Boeckella. The present study aims to update the distribution of Boeckella gracilis in the inland waters of the Araucania region (38-

Use of null models to explain crustacean zooplankton assemblages in waterbodies of alerce andino national park (41°S, Chile). [PDF]

open access: yes, 2012
Los ensambles zooplanctónicos en lagos del norte de la Patagonia se caracterizan por su bajo número de especies y marcada dominancia de copépodos calanoideos. En el presente trabajo se colectaron datos de seis cuerpos de agua del Parque Nacional Alerce

Bridging the Scotia Arc: Climate‐Driven Shifts in Connectivity of the Freshwater Crustacean Branchinecta gaini in Sub‐Antarctic and Antarctic Ecosystems

open access: yesDiversity and Distributions, Volume 31, Issue 7, July 2025.
ABSTRACT Aim To integrate the historical and contemporary connectivity of Branchinecta gaini (B. gaini), in order to better predict future distribution changes within its fragmented, dynamic and isolated habitat range. Location The study covers 20 locations of freshwater ecosystems across B.

Contrasting patterns of MAAs accumulation in two populations of the copepod Boeckella gracilipes

open access: yesPhotochemical & Photobiological Sciences, 2014
The bio-accumulation of mycosporine-like amino acids (MAAs) is common in planktonic copepods that inhabit environments exposed to high levels of solar radiation. MAAs accumulation in copepods can be affected both by extrinsic (environmental) and intrinsic factors (local adaptation, genotype, etc.). Laboratory experiments were performed to study the bio-

Weeding the Biodiversity Patch—A Mesocosm Study of Predation by Boeckella major (Copepoda: Calanoida) on Billabong Zooplankton

open access: yesFreshwater Biology, Volume 70, Issue 7, July 2025.
ABSTRACT We carried out short‐term field experiments (duration 1–3 days) to study the impact of predation by natural densities of Boeckella major on zooplankton in Australian ephemeral billabongs (oxbow lakes). Predation reduced total zooplankton densities by 33.6%–91.9%.

Hurdles in investigating UVB damage in the putative ancient asexual Darwinula stevensoni (Ostracoda, Crustacea) [PDF]

open access: yes, 2013
Ostracoda or mussel-shrimps are small, bivalved Crustacea. Because of their excellent fossil record and their broad variety of reproductive modes, ostracods are of great interest as a model group in ecological and evolutionary research.

Summer changes in the vertical distribution of chlorophyll-a in Boeckella Lake (Hope Bay, Antarctic Peninsula)

open access: yesAntarctic Record, 1996
Vertical distribution of phytoplanktonic chlorophyll-α in Boeckella Lake was studied during summer periods in 1992 and 1993. Two opposite sites subjected to different organic matter inputs from the adjacent penguin rookeries were periodically sampled at ...

Tracing the biogeographic history of the world's most isolated insular floras

open access: yesJournal of Systematics and Evolution, Volume 63, Issue 4, Page 952-973, July 2025.
We inferred the spatio–temporal colonization histories of seven vascular plant lineages (Acaena magellanica, Austroblechnum penna‐marina, Azorella selago, Colobanthus kerguelensis, Notogrammitis crassior, Polystichum marionense, Pringlea antiscorbutica) using phylogenetic, divergence time estimation, and Bayesian Island Biogeographic analyses.
