The cryptonephridial/rectal complex: an evolutionary adaptation for water and ion conservation. [PDF]

open access: yesBiol Rev Camb Philos Soc
ABSTRACT Arthropods have integrated digestive and renal systems, which function to acquire and maintain homeostatically the substances they require for survival. The cryptonephridial complex (CNC) is an evolutionary novelty in which the renal organs and gut have been dramatically reorganised. Parts of the renal or Malpighian tubules (MpTs) form a close

Physicochemical drivers of managed river and agricultural drainage channel macroinvertebrate communities

open access: yesRiver Research and Applications, Volume 37, Issue 4, Page 675-680, May 2021., 2021
Abstract Artificial channels are common features in lowland agricultural catchments, and are a potentially significant habitat for aquatic species. Recent studies have suggested communities in managed rivers and artificial channels are broadly similar, but with some compositional differences.

From Hutchinsonian ratios to spatial scaling theory: the interplay among limiting similarity, body size and landscape structure

open access: yesEcography, Volume 43, Issue 2, Page 318-327, February 2020., 2020
Spatial scaling theory (SST) relates the physical structure of the environment to species coexistence and community assembly. Although SST is a recognized theory in ecology, few studies have evaluated its predictions, producing contradictory results and frequently failing to meet its assumptions.
